[0002] Electromagnetic flowmeter is a new type of flow measurement instrument that developed rapidly in the 1950s and 1960s with the development of electronic technology. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. The structure of the electromagnetic flowmeter is mainly composed of magnetic circuit system, measuring conduit, electrode, shell, lining and converter. Electromagnetic flowmeter is widely used in sewage, fluorine chemical industry, production water, tap water industry, medicine, steel and many other aspects. It is much better than other types of flowmeters in terms of reliability and stability.
