Electromagnetic flowmeter is based on Faraday's law of electromagnetic induction made of a flow measurement instrument, used to measure the flow of conductive liquid volume in the pipeline. Since the components of the electromagnetic flowmeter do not have a rotating part and there is no component that obstructs the flow of the fluid, there is little pressure loss. The measured liquid is only in contact with the pipe lining and the electrode of the electromagnetic flowmeter. Therefore, as long as the electrode and lining material are selected, With good corrosion resistance, wear resistance [2]; easy installation level, vertical, tilt can be installed; high precision, can reach 0.5%; range than large, generally 1:20.
