ELECTROMAGNETIC FLOW METER OF LIQUID METALS Russian patent published in 2011 - IPC G01F1/58 

FIELD: instrument making.

SUBSTANCE: invention refers to flow measuring devices of liquid metals with the help of the method based on interaction of moving liquid with magnetic field. This interaction is subject to electromagnetic induction law according to which e.m.f. proportional to liquid movement velocity crossing magnetic field is induced in liquid. Electromagnetic flow metre of liquid metals has tube made from non-magnetic material, two electrodes welded to external tube surface, magnetic conductor with two poles, induction coil and device for attachment of magnetic conductor to tube. Poles have holes and device has racks located in holes of poles and connected to the tube on the generatrix of the tube, which crosses the axis of poles.

EFFECT: improving measurement accuracy of liquid metals flow.
