DEBITMETRE ELECTROMAGNETIQUE

摘要

An electromagnetic flowmeter designed to use a smaller excitation device and applicable to measurement on tubular channels of various sectional shapes. The electromagnetic flowmeter includes an excitation device for forming a magnetic field perpendicular to an outer wall of a tubular channel, and a pair of electrodes for measuring an electromotive force generated by the movement of the electroconductive fluid across the magnetic field. The electrodes and two magnetic poles of the excitation device are collectively placed on the outer wall at one side of the tubular channel.
