GF642/LF622
Electromagnetic Flowmeter GF642/LF622
General Specificaition
Combined with a multi-functional converter LF622 (Separate type) equipped with its original Noise-suppression Circuit & Advanced Algorithms,The GF642 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*1Communicator) 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. - *3 Modbus is the communication protocol that Modicon Inc. developed.
Physical layer is RS485.
