LF494/LF610  
LF494/LF612  
Field Intelligent Device Series  
Sanitary Electromagnetic Flowmeter  
1S to 4S (25 to 100 mm)  
Introduction  
Sanitary electromagnetic flowmeters LF490 series are  
designed for applications handling food and beverages.  
Sanitary flowmeters must be structured in such a way  
that operation and handling is simple, easy and  
thorough for the purpose of sanitary control such as  
cleaning (CIP/SIP), sterilization and drying. The  
sanitary flowmeter has features provided with normal  
electromagnetic flowmeters and by using sanitary  
fittings for pipeline connections fluid does not remain  
in any place along the detector pipeline. Therefore, it is  
fit for flowrate measurement for food and beverages.  
The electromagnetic flowmeter uses Faraday’s Law of  
electromagnetic induction to measure the process flow.  
The device consists of two units: a detector, through  
which the fluid to be measured flows and in which  
low-level signals proportional to flow rates are  
obtained; and a converter, which supplies excitation  
current to the detector, and amplifies the signals from  
the detector and then processes and converts the  
signals into the 4–20mAdc current signal or

number  
communication signal. With the unique patented  
Mount-Anywhere magnetic field distribution  
Z01207  
technology, the meter is highly immune to upstream  
flow disturbances. Combined with a multi-functional  
converter LF610 (combined type) or LF612 (separate  
type) equipped with its patented Noise-Sentry original  
noise-suppression circuit and advanced algorithms.  
The LF490 has a very high tolerance to noise, giving  
the unit a very stable output even for slurry fluid  
measurement. IR (Infrared) switches enable parameter  
setting of the converter without removing the cover.  
Flow direction can be set in either way, and its unique  
128 x 128 dot matrix LCD display allows the LCD to  
be rotated electronically to 90, 180 and 270 degrees  
without opening the cover.  
The AF900 hand-held terminal (HART*1  
communicator) can be used to communicate with the  
flowmeter from a remote place. PROFIBUS-PA*2  
interface is available as an option.  
*1: HART protocol (Highway Addressable Remote  
Transducer) is a communication protocol for industrial  
sensors recommended by the HCF (HART  
Communication Foundation).  
*2: PROFIBUS is the communication protocol for factory  
and process automation that the PROFIBUS  
Organization recommends. Instead of analog control  
with a conventional analog signal (4-20mA), it is the  
fieldbus which digitizes all signals. Flowmeters support  
PROFIBUS-PA.

Wiring Precautions  
(7) Only one PROFIBUS-PA cable goes through a  
cable gland of the Electromagnetic Flowmeter.  
Please use the junction box at system  
configuration.  
(1) Explosion proof type flowmeters are not  
provided cable glands.  
Refer to the part Cable connection port at  
detector and converter.  
(2) Connect the grounding wire (IV wire 5.5mm² or  
more) to a good earth ground (100or less  
ground resistance). Make the wire as short as  
possible. Do not use a common ground shared  
with other equipment where earth current may  
flow. An independent earth ground is  
recommended.  
(3) The allowable cable lengths between the  
detector and converter for the separate type  
flowmeter depend on the electrical conductivity  
of the object fluid. See Figure 11.

(4) DO1, DO2 (opt.), and DI (opt.) use the same  
common terminal (COM). This COM can not  
connect to other equipments which have their  
own ground terminal. (Power supply for  
connecting to DI or DO, etc…) Need to wire  
separately.

Meter Size  
Wiring Precautions (PROFIBUS)  
To select the meter size:  
(1) For wiring path, avoid places near electrical  
equipment that may cause electromagnetic  
induction or electrostatic induction interference  
(such as a motor, transformer and wireless  
transmitter).  
(2) Use a PROFIBUS-PA cable for signal cable. In  
addition, make sure to use a shielded cable to  
improve noise resistance. Furthermore,  
installation of signal cable in metal conduit is  
recommended.  
See Table 2 to 3 and find meter sizes within the  
velocity of 0.3 to 32.8 ft/s (0.1 to 10m/s ) for a  
specified full-scale (measuring range high limit)  
flow. Select one that has its full-scale velocity  
between 3.0 and 10 ft/s (1 and 3m/s).  
Note: Make sure the full-scale flow rate used for the final  
planning stage stays within 32.8 ft/s (10m/s) in  
terms of flow velocity.  
(3) General PROFIBUS-PA cables are designed for  
indoor use where cables are not exposed to  
humidity, rain, etc. When you install cables,  
make sure to check the operating conditions such  
as the operating temperature range of the cable  
by contacting its manufacturer.  
(4) When you carry out cable end treatment of  
PROFIBUS-PA cable, use a dedicated cable  
stripper etc. so that the core wire of the cable will  
not be nicked or damaged. In addition, for cables,  
be careful of allowable maximum bend diameter  
etc. (Basically, do not install cables in a way  
cables are twisted or bent.).  
(5) Consider installing a PROFIBUS-PA arrester in  
the communication path of PROFBUS-PA so  
that the electromagnetic flowmeter will not be  
affected by lightning etc.  
(6) The electromagnetic flowmeter is not equipped  
with terminating resistors.Use the terminating  
resistor unit for PROFIBUS-PA or junction box,  
if necessary.

Calibration Range  
If the calibration range is not specified, the standard  
range as shown below will be used. If the range is  
specified, we will use the specified range for  
calibration.  
Do not store or install the flowmeter :  
• Where there is direct sunlight.  
• Where excessive vibration or mechanical shock  
occurs.  
Table 4. Standard Flow Range  
• Where high temperature or high humidity  
conditions exist.

• Places that can be submerged under water.  
• Where there is a sloped floor. To put the flowmeter  
temporarily on the floor, place it carefully with  
something, such as a block, to support it so that the  
flowmeter will not topple over.  
Note: The unit of "gal/min" is not exchanged  
(converted) by "m3/h".  
In areas like the following, there may be the case that  
infrared switches do not function correctly. (If these  
are unavoidable, use an appropriate cover.)  
(1) Where unit (operation panel) is exposed to direct  
sunlight, reflection of light onto window pane and  
diffused light reflection.  
(2) Where smoke and steam may occur.  
(3) Where exposed to direct snow, ice or mud.
