ABSTRACT:
A magnetic induction flowmeter has a time-varying magnetic field imposed across the flow passage, and a first and second pairs of electrodes disposed respectively on a first plane dividing the cross section of the flow passage into two equal opposite halves and a second plane offset from the first plane wherein the two electrodes belonging to each pair of electrodes are respectively affixed to the two diametrically opposite sides of the wall of the flow passage, wherein the flow rate of electrically conductive media moving through the flow passage is determined as a function of a differential combination of the electromotive force between the first pair of electrodes and the electromotive force between the second pair of electrodes.
