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*1 communicator) can be used to communicate with the flowmeter from a remote place. PROFIBUS-PA*2  or Modbus*3 interface is available as an option.
