Field Intelligent Device Series
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 4–20mAdc current signal or
communication signal. Thanks to the unique patented
magnetic field distribution technology, the meter is
highly immune for upstream flow disturbances.
Combined with multi-functional converter LF600
(combined type) or LF602 (separate type) equipped
with its original noise-suppression circuit and
arithmetic operation capability, LF410 has high
tolerance to noise, giving 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 128 x 128 dot matrix LCD display allows the LCD
rotated to 90, 180 and 270 degrees with a software.
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 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 the
factory automation and process automation that
PROFIBUS Organization recommends. Instead of
analog control with a conventional analog signal
(4-20mA), it is one kind of the fieldbus which digitized
all signals. Flowmeters support PROFIBUS-PA.

Wiring Precautions (PROFIBUS)
(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.
(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.
10
(7) Only one PROFIBUS-PA cable goes through a
cable gland of the Electromagnetic Flowmeter.
Please use the junction box at system
configuration.
Allowable cable length (m)
Wiring Precautions
(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 (100Ω 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.
(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 12 below.
(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.

Piping Precautions
(1) Design piping so that the flowmeter detector pipe
is always filled with the fluid being measured,
whether the fluid is flowing or not.
(2)The detector has no adjustable piping mechanism.
Install an adjustable short pipe where needed.
(3) The required straight pipe length should comply
with the requirements as follows.
(4) Be sure to grounding the flowmeter according to
below figure.

Meter Size
To select the meter size:
See Figure 13 and find meter sizes within the
velocity of 0.1 to 10m/s for a specified full-scale
(measuring range high limit) flow. Select one that
has its full-scale velocity between 1 and 3m/s.
Note: Make sure the full-scale flow rate used for the
final planning stage stays within 10m/s in terms
of flow velocity.

About establishment environment
Do not store or install the flowmeter in:
• Places where there is direct sunlight.
• Places where excessive vibration or mechanical
shock occurs.
• Places where high temperature or high humidity
conditions obtain.
• Places where corrosive atmospheres obtain.
• Places submerged under water.
• Place where there is slop floor. To put the
flowmeter temporarily on the floor, place it
carefully with something, such as stopper, to
support it so that the flowmeter will not topple over.
In places like the following places, there is the case
that infrared switches do not function correctly. (If
this is unavoidable, use an appropriate cover.
•Places where gets very bright light onto operation
panel. (direct sunlight, reflection light of sunlight
by windowpanes, diffused reflection light of
strength etc.)
•Places where smoke and steam occur near.
•Places where a snow, ice or mud that may attached.
