Electromagnetic Flowmeter GF630/LF620 GF632/LF622

GF630/LF620 (Combined type) image. LF622 & GF632 (Separate type) image. FM(C US) APPROVED image. Certification No. Z01207 image. NSF Certification No.PM09896 For PU lined flowmeter image.

General Specificaition

Combined with a multi-functional converter LF620 (Combined type) or LF622 (Separate type) equipped with its original Noise-suppression Circuit & Advanced Algorithms, The GF630 has a very high tolerance to noise, giving the unit a very stable output even for slurry fluid measurement.

The AF900 Hand-held terminal (HART(*1) Communicator) can be used for remote control. PROFIBUS-PA(*2) or Modbus(*3) 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 automation and process automation that the PROFIBUS Organization recommends.
Instead of analog control with a conventional analog signal (4-20mA), it is one kind of the fieldbus which digitizes all signals.
Flowmeters support PROFIBUS-PA.
*3
Modbus is the communication protocol that Modicon Inc. developed. Physical layer is RS485.
