EFM01 is a series of Intelligent Electromagnetic Flow Meter that comprises of sensor and a smart signal transducer. It can be classified into two structures, integral type and remote type, according to set-up form of the sensor and transducer. For integral type electromagnetic flow meter, transducer and sensor are assembled as a whole and cannot be separated. Likewise, for remote type electromagnetic flow meter, the transducer and sensor can be separated and will be connected via an electric cable.
