What is electromagnetic water flow meter? Electromagnetic water flow meter is an instrument used to measure fluid flow. It works based on Faraday's law of electromagnetic induction, which is that when a fluid passes through an electromagnetic field, the conductive particles in the fluid will generat

Magnetic circuit systems: Mainly used to generate DC and AC magnetic fields. Electrodes: Electrode are used primarily to measure the flow signal generated by the flow of a conductive liquid. In fact, most of the electromagnetic flowmeters made in China are two measuring electrodes.
