Abstract
An apparatus for measuring the flow rate of electrically conductive liquids includes two coils disposed in succession as seen in the flow direction of a liquid. The coils are switched in alternation as a primary and a secondary coil. One of the coils is excited with an alternating current as the primary coil, and voltage induced by the excitation in the other of the coils as the secondary coil is measured.
