ELECTROMAGNETIC FLOWMETER Russian patent published in 2008 - IPC G01F1/58 

FIELD: physics; electricity.

SUBSTANCE: electromagnetic flowmeter contains: exciter with iron cored field coil to form magnetic field, perpendicular to external wall of tubular channel; and pair of electrodes for measurement of voltage formed as conducting fluid medium passes through magnetic field. Pair of electrodes and two magnetic poles of exciter are jointly mounted on external wall on side of tubular channel. Electrodes are symmetrically established by sides of one magnetic pole.

EFFECT: higher accuracy of flow rate measurement in tubular channel with ring cross section.
