Field Intelligent Device – Premium Value 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. Combined with a multi-functional converter
LF620 (combined type) or LF622 (separate type)
equipped with its original patented noise-suppression
circuit and advanced algorithms. The GF630 has a very
high tolerance to noise, giving the unit a very stable
output even for slurry fluid measurement. IR (Infrared)
switches enable the 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 terminal block in LCD side make easy to wire in
case of the combined type.
The AF900 hand-held terminal (HART*
communicator) can be used to communicate with the
flowmeter from a remote place. PROFIBUS-PA*

Modbus*
interface is available as an option.
*1:
HART protocol (Highway Addressable Remote Transducer) is a communication
protocol for industrial sensors recommended by the HCF (HARTCommunication
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 fieldbus which digitizes all signals.
Flowmeters support PROFIBUS-PA.
*3:Modbus is the communication protocol that Modicon Inc. developed. Physical
layer is RS485.
