1/2" to 18" (15 to 450 mm)  
Field Intelligent Device – Mount Anywhere Series - Flanged  
Electromagnetic Flowmeter  
Introduction  
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 4–20 mAdc current signal or communication  
signal. The meter features a Mount-Anywhere  
magnetic field distribution technology, the meter is  
highly immune to upstream flow disturbances.  
Combined with a multi-functional converter LF620  
(combined type) or LF622 (separate type) equipped  
with its patented Noise-Sentry original noise-  
suppression circuit and advanced algorithms. The  
LF654 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.

Specifications  
*
HART protocol (Highway Addressable Remote Transducer) is  
a communication protocol for industrial sensors recommended  
by the HCF (HART Communication Foundation).  
Overall Specifications  
** DevComm2000 Smart Device Communicator available  
through TIC for performing HART device configurations on  
PC or laptop.  
Measurement range in terms of flow velocity:  
0 –1.0 ft/s to 0 – 39.4ft/s (0 – 0.3 m/s to 0 –12 m/s).  
0 – 0.3 ft/s to 0 – 1.0 ft/s (0 – 0.1 m/s to 0 – 0.3 m/s)  
range is available optionally.  
*
PROFIBUS is the communications protocol for factory and  
process automation that the PROFIBUS Organization  
recommends. Instead of analog control with a conventional  
analog signal (4-20 mA), it is fieldbus which digitizes all  
signals. Flowmeters support PROFIBUS-PA.  
Accuracy:  
< 1/2" to 18" ( 15mm to 450mm) >  
±0.2 % of Rate*  
*
Modbus is the communication protocol that Modicon Inc.  
developed. Physical layer is RS485.  
*
*
This pulse output error result is established under standard  
operating conditions at Toshiba admitted flow calibration  
facility. (NIST Traceable)  
Individual meter measurement error may vary up to ±0.5% of  
Rate at 1.64 ft/s (0.5m/s) or more and ±0.3% of rate ±0.039  
inch/s (1mm/s) at 1.64 ft/s or less.  
*
*
Current output: plus ± 8µA (0.05% of span.)  
Refer to individual calibration data for each individual meter's  
measurement error.

(6) The electromagnetic flowmeter is not equipped with  
terminating resistors. Use the terminating resistor  
unit for PROFIBUS-PA or junction box, if  
necessary.  
Wiring Precautions  
(1)Explosion proof type flowmeters are not provided  
with cable glands.  
Refer to the part Cable connection port at detector  
and converter.  
(7) Only one PROFIBUS-PA cable goes through a  
cable gland of the Electromagnetic Flowmeter.  
Please use the junction box at system configuration.  
(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.  
(8) Install a terminator to flowmeter that connected to  
end of Modbus network.  
300  
200  
100  
(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 10.  
50  
30  
20  
10  
(4) DO1, DO2 and DI use the same common terminal  
(COM). This COM can not be connected to other  
equipment which have their own ground terminal.  
(Power supply for connecting to DI or DO, etc…)  
Need to wire separately.

Wiring Precautions (PROFIBUS or

Meter Size  
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).  
See Table 2 and 3 to find meter sizes within the velocity  
of 0.3 to 39.4 ft/s (0.1 to12m/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 39.4ft/s (12m/s) in terms of  
flow velocity.  
(2) Use a PROFIBUS-PA cable or a RS485 twisted-pair  
cable for signal cable.  
In addition, make sure to use a shielded cable to  
improve noise resistance. Installation of signal cable  
in metal conduit is recommended.  
Table 2. Flow Rate and Flow velocity  
(English unit)  
(3) General 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, use a  
dedicated cable stripper to avoid the core wire of the  
cable being nicked or damaged. In addition, for  
cables, be careful of allowable maximum bend  
diameter. (Do not allow excessive twisting or  
bending of cables).  
(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.

Consult a Toshiba representative when choosing

Toshiba International Corp. (Houston) stocks  
Hazardous location certification type  
flowmeters as standard inventory.  
About establishment environment  
Do not store or install the flowmeter:  
• Where there is direct sunlight.  
• Where excessive vibration or mechanical shock  
occurs.  
• Where high temperature or high humidity  
conditions exist.  
• Where corrosive atmospheres exist.  
• Places that can be submerged under water.  
• When placing the flowmeter temporarily on the  
floor, support it, i.e., with a block so that the  
flowmeter does not topple over.  
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.
