Insertion type electromagnetic flow meter

Product Details

The measuring principle of electromagnetic flow meter is based on the electromagnetic induction law of Farady. The sensor is mainly composed of measuring tube with isolate lining, a

pair of electrodes installed by penetration of the measuring tube wall, a pair of coils and iron core to produce working magnetic field. When the conductive fluid flows through the measuring tube of the sensor, the voltage signal in direct proportion to the average flow velocity of the fluid will be inducted on the electrodes. The signal is amplified and treated by the transmitter to realize various display functions.

The converters supplies a stable exciting current to the coil in the sensor of electronetic flow meters to get B constant and amplifies the electromotive force and convert it into standard signals of current or frequency so that the signals can be used for displaying, controlling and processing
