Full bore electromagnetic flowmeter is a flow measurement instrument made by the principle of electromagnetic induction, which can be used to measure the volume flow (flow) of conductive liquid. The magnetic flow sensor has almost no pressure loss, no moving parts inside, and the electrodes and lining is easy to solve the flow measurement of corrosive media. It is not affected by the temperature, pressure, density and flow state of the measured medium during the detection process, and there is no measurement hysteresis.
