A device that measures the rate of flow of a conducting liquid. The liquid is made to flow through a tube, length L, placed in a magnetic field of flux density B (see diagram). Electrodes are placed on a diameter of the tube and the induced e.m.f., E, across this diameter depends on the rate of flow, v, of the liquid:
