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
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

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
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.
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).

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).

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

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
to allow HART communications” on page 19 if HART digital communications is required.
Installation in a hazardous area
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
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.

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 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
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.

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

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
instructions below). In control mode, RL2 ceases to be a fault relay until the On and Off values
are reset to zero.

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

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
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
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.

“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.

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
The volume of the contents is calculated by entering the volume-per-meter of height into the

To derive the 10 profile points, it is necessary to have tabulated or graphical data to relate the

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).

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

towards the surface is sometimes not returned, deflected away from the transmitter, or

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
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.

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.

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.

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
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.
