Electromagnetic Flowmeter of the New Type for the Liquid Metal

The magnetic flowmeter in which inductor represents an electromagnet creating a pulse variable low-frequency magnetic field in the channel of a pipe is described. As a result of the alternating magnetic field is completely excluded the influence of external noise power frequency, significantly reduced the influence of thermo-emf, virtually eliminated the influence of eddy currents, etc.

Keywords: electromagnetic flowmeter, the liquid metal, pulsed magnetic field.
