Permanent magnet type electromagnetic flowmeter introduction

The electromagnetic flowmeter sensor made by the permanent magnet excitation method not only maintains the advantages of the conventional coil excitation electromagnetic flowmeter, but also simplifies the structure of the electromagnetic flow sensor, reduces the manufacturing cost, and can fully exert the eternal effect. The magnet excitation method has the advantages of low power consumption and fast response speed. At the same time, a dynamic feedback control method is introduced to eliminate the polarization voltage in the electrode signal, so that the permanent magnet excited electromagnetic flowmeter is applied to the measurement of general conductive fluid. become possible.
