Transmitter Overview  
2.1  
2.2  
Introduction to the transmitters  
The Mobrey MSP400RH and Mobrey MSP900GH are 4–20 mA loop-powered transmitters, and  
are designed for liquid level measurement applications.  
Theory of operation  
The Mobrey MSP400RH and MSP900GH ultrasonic liquid level transmitters are mounted above  
a liquid and use ultrasonic pulses to continuously measure the distance to the liquid surface. The  
electronics calculate the distance to the liquid level using the time delay between transmitting  
and receiving signals (Figure 2-1).  
When programmed with the bottom reference of the application – usually the bottom of a tank  
– the transmitter calculates the liquid depth (level), and outputs the result as a 4–20 mA signal  
and a digital HART® signal.  
The MSP400RH and MSP900GH can also calculate contents volume or open channel flow, when  
programmed with further application information, and then outputs the result as a  
4–20 mA signal and a digital HART signal.

Components of the transmitter  
The transmitter has a housing containing advanced electronics to generate ultrasonic pulses,  
process the resultant signals, and provide a 4–20mA and HART output.  
Removing the lid reveals terminals to connect a cable (not supplied) for the signal output and  
an external power supply. An LCD inside the enclosure displays the selected measurement.  
Programming is achieved using integral buttons or by remote communication using HART.

System architecture  
The Mobrey MSP400RH and MSP900GH are two-wire, 24 Vdc loop-powered transmitters and  
can be connected to a direct current (dc) power source using two-core, shielded cable.  
The output can be a 4–20 mA analog signal and a digital HART signal.  
Note  
It is possible to use the multi-drop function with the HART protocol. In this case,  
communication is restricted to digital since the current is fixed to 4 mA.  
Each transmitter can be configured locally using the membrane-buttons which are revealed  
after removing the housing cover. The transmitters can be configured remotely by using a  
Mobrey MCU900 Series control unit  
A comprehensive specification for the Mobrey MSP400RH and MSP900GH is in the section

3.2  
Considerations before installation  
The Mobrey MSP400RH and MSP900GH transmitters can be used for level and contents volume  
measurements in open or closed tanks, or for open channel flow measurements.  
The transmitter must be installed in a location where it is protected from ultraviolet radiation to  
prevent long term degradation of the plastics used e.g. shrouded from direct sunlight.  
It is important to correctly position the transmitter for reliable ultrasonic level measurement.  
For maximum accuracy and stability of the level measurement reading, the transmitter should  
always be shrouded from direct sunlight and radiated heat.  
The transmitter may be site-tuned to deal with most application conditions, but it is  
recommended that the following guidelines be adopted where relevant.  
3.2.1  
Safety considerations  
Guidelines  
1.  
Installation must be carried out by suitably trained personnel in accordance with the  
applicable code of practice.  
2.  
If the equipment is likely to come into contact with aggressive substances, it is the  
responsibility of the user to take suitable precautions that prevent it from being  
adversely affected, thus ensuring that the type of protection is not compromised.  
Aggressive substances are acidic liquids or gases that may attack metals or solvents  
that may affect polymeric materials.  
Suitable precautions are regular checks as part of routine inspections, or establishing,  
from the material's datasheet, that it is resistant to specific chemicals.  
3.  
4.  
The equipment must only be cleaned with a damp cloth.  
The equipment is not intended to be repaired by the user and is to be replaced by an  
equivalent certified unit. Repairs should only be carried out by the manufacturer or  
approved repairer.  
5.  
The transmitter is double insulated, and therefore Protective Earthing is not required.  
However, the cable shield/screen should be connected to a suitable ground (earth) at  
6.  
7.  
Note that if the equipment is used in a manner not specified by the manufacturer, the  
protection afforded by the equipment may be impaired.  
To ensure electro-magnetic compatibility in any European member state, it should not  
be installed in a residential area.  
Note  
It is not advisable to mount the transmitter in close proximity to a source of electrical  
noise such as a variable-speed drive, or other high-powered electrical device.

3.3  
Mechanical installation  
Guidelines  
1.  
Mount the transmitter above the liquid surface using the 2-inch thread provided, but  
not closer than 12 in. (0,3 m) to the surface. The transmitter does not detect any liquid  
surface closer than 12 in. (0,3 m) to the transmitter face. (See “Mounting the  
Optional flanges and bracket kits are available to help mounting. (See Rosemount  
Measurement product data sheet IP2045 for accessory part numbers.)  
2.  
3.  
4.  
5.  
The transmitter should be mounted vertically to ensure a good echo from the liquid  
surface. The transmitter beam half angle of the is 6 degrees. (See Figure 3-1 on  
page 10).  
Obstructions in the tank, or well, may generate echoes which can be confused with the  
real liquid surface echo. Obstructions within the beam angle generate strong false  
echoes. Wherever possible, the transmitter should be positioned to avoid false echoes.  
To avoid detecting unwanted objects in the tank or well, it is advisable to maintain a  
distance of at least 1.3 in. from the center line of the transmitter for every foot (11 cm  
per meter) range to the obstruction.  
No false echoes are generated if the transmitter is located near the side of the tank or  
well, and the wall is smooth and free of protrusions. However, there will still be a  
reduction in the echo size. It is recommended that the transmitter be mounted no  
closer than 12 in. (0,3 m) to the wall to avoid a large reduction in the echo size.  
6.  
If the transmitter is mounted in an enclosed tank with a domed top, avoid mounting  
the transmitter in the center of the tank roof because this could act as a parabolic  
reflector and create unwanted echoes.  
7.  
8.  
Avoid applications where heavy condensation could form on the transmitter face.  
If the transmitter is mounted in a stand-off or nozzle, the transmitter face should  
protrude at least 0.2 in. (5 mm) into the tank. If this is not possible, see “Mounting the  
9.  
If the transmitter is used in environments where direct sunlight can cause high surface  
temperatures on exposed surfaces, a sun-shade is recommended.  
10.  
Check that the maximum liquid level will not enter the 12-in. (0,3 m) blanking zone of  
the transmitter.

3.3.1  
Consider the liquid surface conditions  
Guidelines  
1.  
Foaming liquids can reduce the size of the returned echo because foam is a poor  
ultrasonic reflector.  
Mount an ultrasonic transmitter over an area of clear liquid, such as near the inlet to a  
tank or well. In extreme conditions, or where this is not possible, the transmitter may  
be mounted in a vented stilling tube provided that the inside measurement of the  
stilling tube is at least 4 in. (100 mm) and is smooth and free from joints or protrusions.  
It is important that the bottom of the stilling tube stays covered to prevent the ingress  
of foams.  
2.  
Avoid mounting the transmitter directly over any inlet stream.  
3.3.2  
In-tank effects  
Guidelines  
1.  
Stirrers or agitators can cause a vortex. Mount the transmitter off-center of any vortex  
to maximize the return echo.  
2.  
If stirrer blades become uncovered, they create echoes as they pass through the  
ultrasonic beam. The transmitter can learn to ignore these false echoes (see page 56 or  
page 93 for further information).  
10  
     
Reference Manual  
IP2048/RM, Rev AA  
February 2015  
3.  
4.  
In tanks with rounded or conical bottoms, mount the transmitter off-center. If needed,  
a perforated reflector plate can be installed on the tank bottom directly under the  
transmitter center line to ensure a satisfactory return echo.  
Avoid detecting pump casings, as the liquid falls away, by not mounting the transmitter  
directly above pumps. If this is not possible, fine-tuning of the transmitter on-site may  
be required.  
3.3.3  
Mounting the transmitter above the liquid surface  
A 2-in. thread is provided to mount the transmitter. The thread form is either BSPT or NPT, and is  
clearly marked on the hexagon of the transmitter body.  
Note  
The Mobrey MSP400RH and MSP900GH are designed to be mounted in a non-metallic  
fitting or flange. The use of metallic fittings/flanges is not recommended.  
To help installation, flange accessories and bracket kits are available from Emerson Process  
Management (see Product Data Sheet IP2045 for accessory part numbers). The accessory  
flanges supplied are manufactured from PVC and are a full face design. Care must be taken  
when installing to raised face mating flanges on the tank or vessel to prevent distortion of the  
PVC flange by over-tightening the bolts.  
Bracket mounting  
The bracket kit contains a stainless steel angle bracket and PVC threaded disc, which may be  
used to mount the transmitter on a support over the liquid surface. See Product Data Sheet  
IP2045 for accessory part numbers.  
The bracket and disc dimensions are in Figure A-4 on page 69. The combined weight of bracket  
and disc is 16 oz (0,5 kg). For transmitter weight, see “Specifications” on page 63.  
Bracket installation procedure  
1.  
2.  
Attach bracket to the disc using the three screws provided.  
Attach the assembled bracket and disc to a rigid support over the liquid surface. The  
bracket may be bolted to a suitable crossmember (structural section of steel).  
3.  
4.  
5.  
Use PTFE tape on the screw thread (Figure 3-3 on page 13).  
Insert the transmitter into the disc.  
Tighten to a torque of 1.5 lbf.ft. (2 Nm) using the hexagon. Do not use the transmitter  
housing to tighten.

If the tank has a flanged nozzle or stand-off:  
a. Attach the transmitter to a non-metal instrument flange using the threaded  
connection. Tighten to a torque of 1.5 lb-ft (2 N-m) using the transmitter’s hexagon.  
b. The instrument (accessory) flanges supplied by Emerson Process Management are  
manufactured from PVC and are a full face design. Care must be taken when installing  
to a raised face mating flange on the tank or vessel to prevent distortion of the PVC  
flange by over-tightening the bolts.  
c. Ensure the gasket is sitting correctly on the tank flange.  
d. Lower the assembled transmitter and instrument flange onto the tank flange, and  
secure with appropriate bolting to a suitable torque for the flanges.  
If mating to a raised face flange (RF) on the tank nozzle or stand-off, tighten to a  
maximum torque of 10 lb-ft (13.6 N-m).  
3.  
If the tank has a threaded nozzle or stand-off:  
a. Attach the transmitter to the nozzle/stand-off using the threaded connection.  
b. Tighten to a torque of 1.5 lb-ft (2 N-m) using the transmitter’s hexagon.  
Note  
If the transmitter face does not protrude into the vessel, note the dimensions in  
Table 3-1 on page 3-13 for Figure 3-3, and ensure that the nozzle/vessel weld is smooth  
and free from internal weld beads or other projections.

Open channel flow installations  
There are normally two distinct parts to an open channel flow measurement system; the  
primary element (flow structure) and the secondary element (Head measurement instrumenta-  
tion). For accurate open channel flow measurement, both parts of the system must be correctly  
installed.  
This section explains the important parts of installing the transmitter (secondary element). The  
flow structure (primary element) installation can be referenced in the British (BS3680) or ISO  
International standards.  
Positioning of the transmitter is critical, and should be the correct distance upstream from the  
flow structure as stated in the relevant standard for your country. For example, in the ISO  
standards, the distance should be four to five times the maximum height of the water (H ) for  
max  
a thin plate weir, or three to four times H  
for a flume. For optimum accuracy, the  
max  
transmitter’s front face should be positioned at a height equal to the maximum flow depth plus  
14 in. (0,35 m).

Note  
The transmitter should be free from a situation where it is likely to 'drown' (refer to  
relevant Standard for further information).  
The MSP400RH and MSP900GH have the option of a Remote Temperature Sensor for  
temperature compensation (see “Remote temperature sensor” on page 19).  
The temperature sensor should be mounted in a location where it can get an accurate  
air temperature measurement and is protected from sunlight.  
If the flow structure permits, mount the transmitter within the flow channel or  
chamber. Shroud the transmitter from direct sunlight for maximum accuracy and  
stability.

Electrical installation  
3.4.1  
Connecting the cable(s) to the transmitter  
The Mobrey MSP400RH and MSP900GH are two-wire loop-powered transmitters accepting  
power supplies as follows:  
MSP400RH:12 to 40 Vdc (non-hazardous area only)  
MSP900GH:12 to 40 Vdc (non-hazardous area) or 12 to 30 Vdc (hazardous area)  
Note  
To comply with the CSA approval, a transmitter must be powered from a Mobrey  
MCU900 Series control unit, or a class 2 or separate extra-low voltage (SELV) source.  
Other devices may reset if connecting the transmitter to a multi-drop system while the  
loop is powered. De-energize the loop to avoid devices being reset  
Each transmitter is supplied with two cable entries. A suitable conduit system or cable gland  
must be used to maintain the weather-proof rating and hazardous area protection. Any unused  
entry must be sealed with a suitably rated blanking plug.  
A two-core, shielded/screened cable is required for external power supply and output signal  
connections. The cable is not supplied.  
Connect the cable(s) to the transmitter  
1.  
2.  
3.  
4.  
Make sure that the power supply is disconnected.  
Undo the three cover screws and then lift the transmitter housing cover.  
Pass the cable through the cable gland/conduit.  
Connect the cable wires:  
5.  
6.  
Connect the cable shield/screen to a suitable ground (earth) at one end only.  
Replace the cover, tighten the cable gland, and connect the power supply.  
What to do after completing the cabling  
To maintain the weather-proof rating and hazardous area protection of the transmitter, ensure  
all cable glands, blanking plugs, and seals are in good condition.  
Check that the cover seal is in good condition, and not twisted or misaligned in the seal location  
groove. When replacing the cover, tighten the three cover screws evenly to exert uniform  
pressure on the cover seal.

Relays  
The MSP400RH has two integral relays which may be used for fault indication or control  
purposes. These relays are for light duty and should be used as signal relays only, with control  
functions being performed by external control relays.  
Relay 2 is defaulted as a 'fault' relay - normally energized - but may be re-configured  
on-site as a set-point relay if required.  
Relay status indicators are on the LCD inside the housing (see “Display and  
3.4.3  
Connecting the cable wires to the MSP900GH  
The MSP900GH is for intrinsically safe installations.  
Note  
Make sure the power supply is off when connecting the transmitter.  
Installation in a non-hazardous (ordinary location) area  
Connect the cable wires to the transmitter as shown in Figure 3-8 on page 19. See also “Wiring  
to allow HART communications” on page 19 if HART digital communications is required.  
Installation in a hazardous area  
Connect the cable wires to the transmitter as shown in Figure 3-8 on page 19. See also “Wiring  
to allow HART communications” on page 19 if HART digital communications is required.  
When the MSP900GH is powered by a Mobrey MCU900 Series control unit, no safety barriers are  
required as the output from the control unit is Intrinsically Safe.  
If powering the transmitter from any other power supply, ensure a suitable intrinsically safe  
barrier is fitted in the non-hazardous (safe) area. The barrier must be chosen such that its output  
parameters Uo, Io and Po are less than Ui, Ii and Pi of the transmitter (see Appendix B: Product  
Certifications). The sum of the capacitance and the inductance of the transmitter and the  
connecting cable fitted must not exceed the maximum specified for the barrier chosen.  
Note  
Make sure that the instruments in the loop are installed according to intrinsically-safe  
field wiring practices and control drawings, when applicable.

Remote temperature sensor  
The MSP400RH and MSP900GH accept input from a Mobrey Remote Temperature Sensor  
(see Product Data Sheet IP2045 for accessory part numbers).  
This is a thermistor-based temperature sensor designed for use with the MSP400RH and  
MSP900GH.  
Full installation instructions are supplied with the temperature sensor, but it should be mounted  
out of direct sunlight in a position so that it can give a representative reading of the air  
temperature between the liquid surface and the transmitter.  
Note  
Do not connect any other temperature sensor to the MSP400RH or the MSP900GH.  
3.4.5  
Wiring to allow HART communications  
If HART communications is required, a 250 Ohms (minimum), 0.25 W load resistor must be  
installed in the loop. (See “Dimension drawings” on page 68).  
Note  
When the transmitter is used with a Mobrey MCU900 Series control unit, there is no  
need to install an external load resistor in the loop because a suitable resistor is built in  
to the control unit.  
19  
       
Reference Manual  
February 2015  
IP2048/RM, Rev AA  
If the transmitter is being supplied through a safety barrier, ensure the type chosen will pass  
HART information.  
After the load resistor is installed, a Field Communicator can be connected across the load  
resistor. It is the responsibility of the installer to ensure that any Field Communicator used in the  
hazardous area is suitably certified.  
Note  
Make sure that the instruments in the loop are installed according to intrinsically-safe  
field wiring practices and control drawings, when applicable.  
3.4.6  
Lightning / Surge protection and other loop devices  
If the area is prone to lightning strikes or voltage surges, a suppressor device may be installed  
between the transmitter and the control unit.  
If an additional loop-powered device or separately powered device is included in the two-wire  
loop, ensure the transmitter receives a minimum voltage of

Starting up  
4.1  
Overview  
Mobrey MSP400RH and MSP900GH ultrasonic liquid level transmitters are operated from a  
menu of parameters, each held in a specific memory location within the transmitter. The  
memory locations may be pictured as a matrix, and navigated for programming the instrument  
using and steps.  
The Integral Display Menu structure is shown in Appendix C: Integrated Display Menus.  
The transmitter is pre-programmed at the factory with a value in each parameter location so  
that when the power is first applied, the transmitter gives a sensible reading. Default values are  
The MSP400RH and MSP900GH are HART-enabled, allowing remote communications with the  
instrument. The transmitter can be programmed using a suitable HART-compatible master, or  
locally using the push-buttons provided inside the transmitter.  
Note  
This section details the local programming. Refer to Appendix F: Configuring Using  
HART if using a Mobrey MCU900 Series control unit or a Field Communicator.  
4.1.1  
Display and push-buttons  
The integral display allows up to five characters. In running mode, the Primary Value (PV)  
measurement is displayed. In programming mode, data is displayed to assist with  
programming.  
To the left of the main display are four arrow icons; one will be illuminated to indicate the  
selected duty.  
To the right of the PV display on The MSP400RH are two arrow icons that indicate the status of  
the transmitter relays. When illuminated, they indicate the relay contact is closed.  
Under the PV display is a text string indicating the units of measurement. The transmitter will  
illuminate only those characters applicable to the units of measurement chosen.  
To the right of the text string is an echo received icon. It is made up of three arc segments that  
continuously indicate the strength of the echo received (minimum, average, and good).

Power up  
When the power is turned on, the transmitter takes several seconds to initialize. The display will  
run a set-up routine, first illuminating all display characters, and then showing the software  
revision number. Finally, a full set of zeros is displayed while the microprocessor identifies the  
correct return echo. After these checks are complete, the display indicates the live  
measurement based upon the factory default values in memory.  
On a new instrument aimed at a good target, the transmitter calculates a level reading based  
upon the default value for the bottom reference.  
The duty icon against the letter L on the top plate, and the RL2 icon on The MSP400RH, will be  
illuminated. The RL1 icon on the MSP400RH may be illuminated, depending on the level  
calculated by the transmitter at this time.  
The transmitter is now ready to be set-up with details of the application.  
The transmitter may be programmed prior to, or after, installation. All programmed data is  
retained in the transmitter memory after the power is turned off.

Before programming  
Important notes to help you program the transmitter  
Do not allow rain, or water, to enter the transmitter during programming or the circuit  
boards may be damaged.  
See the instructions below on how to use the push-buttons to navigate through the  
programming menu and select or enter application data.  
Push the buttons firmly, but not too hard, to avoid damaging the circuit boards. Also, to  
avoid entering incorrect data, do not push the buttons too fast.  
Holding down the green button scrolls through any option list.  
Pressing the red button at any time will return you to the previous level in the menu.  
If the red button is pressed after new data has been entered, the new data will  
automatically be saved.  
The transmitter has a “re-set default values” routine that reloads the transmitter  
memory with the factory default values. This will clear the memory of any previous data  
entered on site.  
4.2  
Programming  
Menu structures for this section are in Appendix C: Integrated Display Menus (page 75).  
If using a HART Master Device for programming the MSP400RH or the MSP900GH, refer to the  
following sections for menu structures and parameters:  
4.2.1  
Overview  
Transmitter programming is most easily accomplished by first selecting the duty that the  
transmitter is to perform. After a duty is selected (see below), a “mini-wizard” programming  
assistant is invoked that asks only for information relevant to the selected duty. Entered data  
allows the mini-wizard to populate relevant parameters with application specific data and select  
the next step required to configure the transmitter.  
Note  
It is advised to enter the “dutY” menu when programming the transmitter, initiating  
the mini-wizard to assist with programming.  
After programming is complete, the data entered or calculated by the transmitter can be  
reviewed by going through the menu using the green button This is a manual navigation of  
the menus, and all menus are shown regardless of the duty selected; the mini-wizard is only  
initiated when a duty is selected. Ignore menus that do not relate to your application.

This menu is offered if the selected duty is Flow and a profile (e.g. “SPEC.C”) requires the  
manual editing of a power factor in the formula:  
Flow Q = kh* (where * = the power factor)  
The transmitter is pre-programmed with appropriate power factors for many standard flow  
profiles, and will automatically select the appropriate factor (See Table 4-1 on page 4-30).  
Alternatively, the power factor may be edited to suit a specific flow structure.

K-factor for the flow law  
Screen display:  
SCALE  
Factory default value:  
1.000  
Note  
If a flow duty has been selected, the value entered into this parameter is in effect the  
K-factor in a flow law of the form Flow Q = kh*.  
If a Distance, Level or Contents (Volume) duty has been selected, the value entered into this  
parameter is a factor used to scale the measured distance, level, or volume.  
For a Level or Distance duty, the scaling factor is normally left at the value calculated by the  
transmitter (depending upon previously entered data and duty selected), or the default value of  
1.000.  
For a linear Contents duty, enter a scaling factor to convert the level measurement to a volume  
measurement. If the measurement units are “m”, enter the volume contained in 1 m of liquid  
height in the tank. If the units of measurements are “ft”, then enter the volume contained in 1  
ft. of liquid height in the tank.

Setting the output damping  
Screen display:  
d
Factory default value:

The damping value is a time constant in seconds, and is applied as smoothing to the displayed  
PV and the output current.  
A new value may be entered up to 999 seconds. A large value will have the effect of smoothing  
out rapid changes to the PV value, and smooth out the effects of turbulence and ripples on the  
liquid surface. (It would be unusual to select a value greater than 30 seconds.)  
A value of zero may be edited, in which case no smoothing is applied to the Current Output and  
transmitter readings immediately change the output.  
Note  
A damping time of zero will not necessarily give an immediate response because the  
MSP400RH and MSP900GH transmits nominally at once per second.

Setting the relay on and off points (MSP400RH)  
The MSP400RH has two integral signal relays. Both relays are the SPST (Single Pole, Single  
Throw) type.  
RL1 is factory-set to be a control relay. It may be set to energise at any value of PV, and de-  
energise at any other value of PV. Setting the on and off points to a common PV will turn the  
relay off. The on value may be greater or smaller than the off value, and vice-versa.  
RL2 is factory-set to be a fault relay. In this mode, it de-energizes under Lost Echo (LE) or fault  
conditions. The relay de-energizes if the power fails.  
The mode of RL2 may be changed to control mode by entering on and off values (use RL1

Learn about echoes from false targets  
Screen display:  
Lrn  
The MSP400RH and MSP900GH has an easy-to-use “Lrn” (Learn) routine that allows the  
instrument to learn up to four false echoes, which can then be ignored in future operations.  
If the application is simple and there are no false echoes, press the green button to exit the  
menu and return to the PV display.  
After the transmitter is in operational, if an echo other than the true liquid surface echo is  
detected and an incorrect level reading is indicated, the instrument can learn to ignore this false  
echo. The “Lrn” routine may be used at any time, either during or after setting-up or if a  
problem occurs later.  
Note  
This menu option is in the engineering menu “Eng”. See “Accessing the engineering  
menu” on page 49 or see Figure C-3 on page 79 for a map of the menu structure.  
To store a false target echo  
1.  
After entering the “Eng” menu (see the note above), press the green button   
repeatedly until “Lrn” is indicated.  
2.  
Press the blue button to enter the “Lrn” menu. The display indicates “LrnX” where  
“X” (0 to 4) is the number of stored false target echoes.  
3.  
4.  
To store a new false echo, press and hold the blue button for five seconds.  
The display alternately flashes “Lrn” and the false target position. After four seconds,  
the false target position is stored and the display re-indicates “LrnX”.  
5.  
Press the red button to save this false echo and exit to the menu. If this false echo  
shouldn't be saved, press the blue button to exit the menu.  
6.  
7.  
To store another false target echo, re-start at step (2).  
To get to the next menu option, press the green button .  
Note  
If there are four false echoes stored (“Lrn4”), the transmitter will not allow another  
echo to be stored until the memory is cleared (see procedure below).  
When a false echo is stored, the transmitter sets up a 'window' around the false target  
and ignores any echo from that window, unless the echo received from the liquid  
surface is larger than the stored false echo. There may be no change in the transmitter  
output current while the liquid level moves through this window, which is equivalent to  
a distance of 20 cm.

Setting the ambient temperature  
Screen display:  
t
Factory default value:  
Auto  
The transmitter has an integral temperature sensor to measure the temperature of the air space  
surrounding it so that the speed of sound can be correctly computed for sending pulses. The dis-  
tance-to-target is then calculated using the formula:  
Distance to target = Speed of Sound in air * (Time for echo to return / 2)  
Auto indicates the transmitter is set to continuously measure the temperature using the integral  
temperature sensor. It may, occasionally, be necessary to over-ride this automatic monitoring  
and fix the temperature to be used in speed-of-sound calculations, for example if the air  
temperature is not uniform and the temperature being recorded is not the true air temperature.

False echoes under certain ambient operating  
conditions  
In applications where elevated ambient temperatures of around 122 to 140 °F (50 to 60 °C) are  
experienced, together with poor liquid surface conditions (excessive surface agitation, foam,  
etc.), the transmitter may see a false echo and report a false high level measurement.  
To overcome this issue, the near zone threshold (Threshold 1 Size P048) was changed from  
software version V4.02 onwards to provide the following duty:  
Threshold 1 Size P048  
The factory default value of this parameter is 6% (prior to V4.02 software this had a  
default value of 4%).  
If Threshold 1 Size P048 is equal to 6.0 (default), the transmitter automatically adjusts  
the value of the initial threshold in use at elevated temperatures to eliminate false high  
level readings.  
If Threshold 1 Size P048 is set to 6.0 and Threshold 1 Time P043 is equal to 2.9 (default),  
the transmitter simultaneously adjusts the value of the initial threshold time in use at  
higher temperatures.  
If Threshold 1 Size P048 is not equal to 6.0, the unit uses that value and Threshold 1  
Time P043 will be as programmed.  
Note that operating at elevated ambient temperatures over 140 °F (50 °C) may have an  
impact on the accuracy of the liquid level reading when the liquid level is within  
approximately 0.5 m of the transducer face. The accuracy may be reduced from  
2.5 mm to +2.5/-5.5 mm or, in extreme conditions, +2.5/-8.5 mm.  
Note  
Parameters P048 and P043 are accessible only when using a Field Communicator or a  
Mobrey MCU900 Series Control Unit. The main descriptions for these parameters are

Configuring Using HART  
F.1  
Overview  
The MSP400RH and MSP900GH support HART communications, which may be used to program  
or interrogate the transmitters from any point on the two-wire loop. This section contains  
information on configuring the transmitters using a Field Communicator or a Mobrey MCU900  
Series Control Unit.  
Mobrey MCU900 Series Control Unit  
The product reference manual (IP2030/RM) provides full instructions on installation and  
operation of the control unit. There is also a quick installation guide (IP2030/QS). Both of these  
product documents are available in the Adobe PDF format, and can be downloaded from the  
Mobrey brand pages at www.emersonprocess.com.  
A full menu map showing how to access transmitter parameters using the control unit’s menu  
system is in Appendix D: Mobrey MCU900 Series. For convenience, the parameter identification  
numbers (P*** and D***) are used in parameter headings and descriptions in this appendix.  
When using the control unit, use the Enter ( ) key to start editing a configuration parameter  
and then use the arrow keys to change the setting. Changes are confirmed by pressing the Enter  
key, or abandoned by pressing the Esc key. Commands e.g. Set As Empty are run using the  
Enter ( ) key.  
Field communicator  
For convenience, Field Communicator fast key sequences are labeled “Fast Keys” for each  
software function below the appropriate headings. A full menu map showing how to access  
transmitter parameters using the Field Communicator is in Appendix E: Field Communicator.  
Example software function  
Fast Keys  
1, 2, 3, etc.  
When using a Field Communicator, some configuration changes are sent to the transmitter by  
pressing “SEND”.  
Connect the Field Communicator leads to the transmitter, and turn on the Field Communicator  
by pressing the ON/OFF key. The Field Communicator will search for a HART-compatible device  
and indicate when the connection is made. If the Field Communicator fails to connect, it  
indicates that no device was found. If this occurs, check the lead connections and re-try.

Simulation of PV  
Fast Keys

The transmitter simulations automatically cycle the PV between the bottom of the tank and the  
nearest measurable distance. The cycle direction is given by the name of the simulation mode  
selected. Simulation modes are:  
Run up” – cycles up, and then down, repeatedly until stopped.  
Run down” – cycles down, and then up, repeatedly until stopped.  
Run from Zero” – as “Run up” except the PV initially starts from 0.  
A single cycle takes 100 seconds to complete. The Current Output responds according to the PV.  
The cycling may be paused with the “pause” mode, and then re-started by selecting another  
simulation mode. To stop the cycling, select the “normal” mode.

This selects the shape of a tank or an open channel, and establishes the linear or non-linear  
relationship between the live liquid level (height) and the process value (PV) derived from that  
level.  
Note  
The display (reported) measurement units for the output process value (PV) are set using  
the Primary Variable Units parameter (page 120). However, this does not automatically  
re-scale the PV. Use parameter PV Scale Factor (page 121) to manually re-scale the value.  
The transmitter is pre-programmed with popular profiles that are mathematical formulas to  
convert a linear level reading to a flow or volumetric process value (PV). The Current Output is  
then driven by the flow or volumetric PV. The profile options are described in the following

Contents (volume) measurement  
There are five shape options available to select, including:  
Tank Shape/NLP (P011) = “Linear”  
This default setting is for level or volume (content) measurements involving a tank with a  
constant cross-section. When “Linear” is selected, the level or volume is the liquid height  
above the zero level multiplied by a scaling factor. If volume is not required, the Scale Factor  
parameter (page 121) is set to 1.0 unless requiring other measurement units for the output PV.  
The volume of the contents is calculated by entering the volume-per-meter of height into the  
Scale Factor parameter (page 121). If the liquid level is being measured in feet or inches, enter  
the volume-per-feet or volume-per-inch respectively.  
Tank Shape/NLP (P011) = “Special Plot”  
When selecting “Special Plot”, parameters Profile Point 1 to 10 (page 124) can be edited  
to plot the unique profile of an irregular shaped tank or open channel (see Figure F-2).

To derive the 10 profile points, it is necessary to have tabulated or graphical data to relate the  
process value (PV) to the live liquid height. Figure F-3 on page 114 shows an example graph of  
PV versus Liquid Height. In the example, 60% of the maximum height on the X-axis relates to a  
112  
       
Reference Manual  
IP2048/RM, Rev AA  
February 2015  
percentage of the maximum PV on the Y-axis. The related percentage, say 55%, is entered into  
parameter Profile Point 6.  
The transmitter will interpolate linearly between the plotted points to give an accurate curve fit,  
which will determine the output PV from the live level (height) measurement.  
Each live level measurement is converted into a percentage (0 to 100%), which is proportional to  
the maximum height. In graph terms, the converted percentage corresponds to an X ordinate  
on the X-axis. Using this X ordinate, the Y ordinate is then calculated to get a percentage  
proportional to the maximum PV. This percentage is multiplied by the maximum height to get  
the output process value (PV).  
Setting-up procedure for “Special Plot” option:  
1.  
2.  
3.  
4.  
5.  
Select the displayed (reported) units for the output PV (see page 120).  
Draw the graph of PV versus Liquid Height, and note the maximum points.  
Enter the maximum liquid height into Profile Height (page 122).  
Enter the maximum volume or flow into PV Scale Factor (page 121).  
Enter the distance from the transmitter face to the zero point (Y=0) into the  
Bottom Reference parameter (page 105).  
6.  
Use parameters Profile Point 1 (P030) to Profile Point 10 (P039) to enter the  
percentage values that relate to the X-axis fixed percentages.  
Note  
The origin (0,0) is always used as the start point. It is not a parameter.  
It is possible the process value (PV) at the maximum height is less than 100% of the  
maximum volume or flow. (See Figure F-4 on page 114).

converts (scales) the level measurement into alternative units before being output. Enter a value  
of 1.0 if alternative units are not required.  
Volume measurement  
When the PV is a volume measurement from a standard non-linear-shaped tank e.g. cylinder or  
sphere, use this parameter to enter the volume of the ideal shaped tank (see Figure F-5 on  
When the PV is a volume measurement from a regular-shaped tank  
e.g. square or rectangular, use this parameter to enter the volume change per unit of the base  
unit.  
When the PV is a volume measurement from an irregular-shaped tank, use this parameter to  
enter the maximum volume. See also the Special Plot section on page 112 for defining the irreg-  
ular-shaped tank.  
Open channel measurement  
When the PV is the flow rate in a standard open channel, use this parameter to enter the scale  
factor (‘k’ term) in a flow rate calculation. See “Flow measurement” on page 116 for selecting a  
standard flow profile.  
When the PV is the flow rate in an irregular-shaped open channel, use this parameter to enter the

Upper range value (P015)  
Fast Keys  
2, 2, 1, 3  
This defines the process value (PV) represented by a 20 mA output from the transmitter.  
The span of the 4–20 mA current output is defined by the Upper Range Value parameter and  
the Lower Range Value parameter (page 126).  
Consider a tank with a 120 gallons capacity. When full, a 20 mA output current is required from  
the transmitter. Therefore, the upper range value is set to 120 if the PV is in gallon units. The  
lower range value is typically set to 0 (gallons) for the 4 mA output to indicate an empty tank.  
The upper range value can be less than the lower range value, in which case the current output  
will decrease for an increasing process value (PV).  
Note  
The upper range value is automatically overwritten when the Tank Shape/NLP parameter is  
used to select a flume flow profile, but the populated value can still be edited if required.  
See Table F-1 on page 119 for the 20 mA point values.  
The displayed units are selected using the parameter Primary Variable Units

The damping value is a time constant in seconds, and is applied as smoothing to the level  
reading and the output current.  
A larger value will have the effect of smoothing out rapid changes of level, and smooth out the  
effects of turbulence and ripples on the liquid surface.  
A value of zero can be edited, in which case no smoothing is applied and transmitter readings  
immediately change the output.

The pulse repetition frequency of the transmitter is one pulse per second, which means that  
the system response time cannot be faster than this.

On the MSP400RH, RL2 is factory-set to be a fault relay. In this mode, it de-energises under Lost  
Echo (LE) or fault conditions. The relay de- energises if the power fails.  
The mode of RL2 may be changed to control mode by entering on and off values (use RL1  
instructions below). In control mode, RL2 ceases to be a fault relay until the On and Off values  
are reset to zero.  
All relay set-point values must be entered in the units chosen for the PV.

Lost echo delay (P021)  
Fast Keys  
2, 2, 5 [or 6], 1  
In pulse echo level measurement systems, ultrasonic pulse echoes are sometimes lost due to  
adverse liquid surface conditions such as turbulence or foam. The ultrasonic pulse transmitted  
towards the surface is sometimes not returned, deflected away from the transmitter, or  
128  
             
Reference Manual  
IP2048/RM, Rev AA  
February 2015  
attenuated significantly. In these conditions, the transmitter holds the last valid data and  
transmits another pulse to see if the echo is returned.  
Lost Echo Delay (P021) defines the period that the transmitter will hold and display the present  
valid surface measurement, waiting to update the measurement when the echo is recovered.  
A “lost echo” fault condition is signalled if the Lost Echo Delay period ends with no valid echoes  
returned.  
A valid returned echo occurs inside a 'window' on either side of the liquid level. The 'window'  
increases as the range to the target increases. All echoes within the ‘window’ are monitored and  
averaged to smooth of the liquid level output under turbulent conditions.  
Any returned echo from closer than the liquid surface is considered valid if a minimum required  
number of echoes (page 136) have been received. The output then changes to this new value.  
Any echo returned further than the liquid surface and outside the 'window' is ignored. However,  
if a lost echo condition is developing and a period (Lost Echo Delay divided by two(1)) has  
elapsed, any echoes received from further away targets are treated as valid. The liquid level  
measured changes to the new value after receiving four such echoes.

This defines what happens to the process value (PV) and output current when a “lost echo”  
condition exists (see page 128).  
“MINIMUM” action  
The PV is forced to zero while a “lost echo” condition exists.  
In addition, the two-wire loop current changes to indicate a low or high alarm as specified by the  
model code (see “” on page 70). The current remains at that level until the correct target echo is  
recovered.  
“MAXIMUM” action  
The PV is forced to the maximum while a “lost echo” condition exists. The maximum PV is the  
value that occurs when an echo is received from the transmitter face.  
In addition, the two-wire loop current changes to indicate a low or high alarm as specified by the  
model code (see “” on page 70). The current remains at that level until the correct target echo is  
recovered.  
“HOLD” action  
The current output is held at the last good PV value.

Speed of sound (P024)  
Fast Keys  
2, 2, 5 [or 6], 4  
This is for entering the speed of sound of the gas above the liquid surface (ullage gas) in a closed  
tank at 32 F (0 C) (see Table F-2).  
A new speed of sound is then calculated for the ullage gas at the temperature and humidity level  
in the tank (see calculated Speed of Sound on page 158). The correction for temperature  
effects is made using the parameter Temperature (page 132) and assumes the entered Speed  
of Sound (P024) value is valid at 32 F (0 C).  
For systems monitoring aqueous liquids with air (or nitrogen) as the primary gas in the ullage  
space, the entered Speed of Sound (P024) value should be 1088.6 ft/s (331.80 m/s). This is the  
most accurate setting for temperatures in the range of 32 to 104 F (0 to 40 C).  
If the tank vapor space is filled with a different gas, a revised Speed of Sound (P024) value should  
be entered. Gas mixtures have speed of sound values calculated as an average according to the  
proportion of the gases present.

percentage defining the minimum signal level, above which an echo is detected and treated as a  
potentially valid surface or target.  
When the threshold is set to “Auto”, the sensitivity is automatically adjusted over a range of  
values, depending on the echo strengths being received. The threshold is adjusted to one  
quarter of the peak value of the largest signal detected to give best overall performance. The  
live value is indicated in the read-only Threshold In Use parameter (page 160).  
The threshold can be a constant value, which may be needed to overcome on-site difficulties or  
special conditions.

Pulse repeat (P041)  
Fast Keys  
The nominal rate of repetition for ultrasonic pulses from the transmitter is one pulse per second.  
If two transmitters were located within the same tank, it is possible this would allow ultrasonic  
pulses from one unit to be received by the other. This can be prevented by having both  
transmitters operate with different rates of pulse repetition, which means this interference is  
rejected as not consistent (pulse-to-pulse). Pulse Repeat allows the pulse repetition interval to  
be adjusted by increments of 0.1 seconds.  
This parameter is not available in the MSP Series DD (Device Descriptor) file.

Target frequency (P045)  
Fast Keys  
2, 2, 7 [or 8], 6, 1  
This sets the frequency used for transmitting an ultrasonic pulse. The optimum frequency  
depends on the characteristics of the transmitter’s piezoelectric crystals, which are affected by  
temperature.  
The transmitter has a look-up table to select a frequency value to give the highest echo strength  
from the prevailing conditions at the site. This look-up function operates when Target  
Frequency (P045) is set to “Auto”.  
Site conditions sometimes require a fixed frequency. Target Frequency (P045) is used to set a  
fixed frequency, but the actual frequency value used is selected from the look-up table and the

The size of the echo returned from a surface depends on the surface range, gas composition and

foam, and draughts), and other factors.  
The received echo strength may vary from pulse-to-pulse but monitoring the read-only

Echo success (D912)  
Fast Keys  
3, 1, 2, 1, 3  
This is a measure of the quality of the echo returned. It is a percentage indicating the success  
rate achieved from the last ten pulse transmissions.  
The success rate may fall below 100% due to the effect of extreme surface turbulence or stirrers,  
which might return a surface echo that is then rejected by the transmitter.  
A surface echo might be rejected because it is outside the allowed 'window', set-up to establish  
the true liquid level. This rejects invalid readings on the principle that liquid levels do not change  
very quickly (see “Lost Echo Delay” on page 128).  
One rejected surface echo causes Echo Success to decrease by 10%, but a subsequent valid  
surface echo increases the percentage by 10%. The transmitter is biased to ignore sudden liquid  
level changes.
