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.

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 (100 or 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.

(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.

(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…)

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.

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.
