ELECTROMAGNETIC METHOD OF MEASURING FLOW RATE OF LIQUID METAL Russian patent published in 2020 - IPC G01F1/58 

FIELD: machine building.

SUBSTANCE: proposed invention relates to instrument-making, namely to measurement technique of liquid metals consumption by means of electromagnetic method, that is method based on interaction of a moving electroconductive liquid with a magnetic field. Electromagnetic method of measuring flow rate of liquid metals in a pipe consists in creation of a low-frequency pulse bipolar magnetic field in a pipe channel, in conversion by a moving liquid flow on the basis of Faraday law of this magnetic field into an electric signal between two electrodes welded to external surface of the pipe, and calculation of flow rate. At that, on the pipe there is a coil containing at least one coil covering the pipe central cross-section, with the help of the coil the magnetic field component is measured, which is directed along the pipe axis in the channel central cross-section, and as a result of its measurement, calculation and correction of flow meter reading eliminating effect of magnetic field deformation on measurement result of liquid metal consumption.

EFFECT: technical result is higher accuracy of measuring flow rate of liquid metals.
