METHOD OF MEASUREMENT OF LIQUID METAL FLOW VIA CIRCULATION CIRCUIT FLOW SECTION Russian patent published in 2013 - IPC G01F1/00

Abstract RU 2490597 C2

FIELD: instrument making.

SUBSTANCE: proposed method comprises measurement of working channel electric resistance between current feed buses at liquid metal zero flow rate and working temperature, forcing liquid metal by electromagnetic pump through said working channel, measuring electromagnetic pump supply current and voltage drop at its working channel between current feed buses to calculate the flow by the formula. Said formula allows for liquid metal flow rate, pump feed current, voltage drop at pump working channel, electric resistance between current feed buses at liquid metal zero flow rate and constant defined by graduation at pump working temperature.

EFFECT: simplified design.
