[0002] Electromagnetic flowmeter is also called electromagnetic flowmeter. Flow measurement is the science of studying the change of mass of matter. The law of mutual change of mass is the basic law of the connection and development of things. Therefore, its measurement object is no longer limited to the traditional pipeline liquid. Wherever the change of mass is required, there is the problem of flow measurement. Flow, pressure and temperature are listed as the three major detection parameters.
