ABSTRACT:
A low power, reliable velocity transducer is particularly adapted to measure the flow of a fluid in a metallic pipe. A pair of U-shaped cores of high magnetic permeability are arranged side-by-side and surrounded by an energizing coil to provide an electromagnet of high electromagnetic energy conversion efficiency and low susceptibility to stray and shunt fields. A triad of electrodes is mounted thereon to detect a resultant electric field from the interaction of the velocity of the flow with the imposed magnetic field. Conductors engaged to the measuring electrodes effect a generally S-shaped geometry so that the signals applied to a differential amplifier to derive the E field waveforms are unencumbered by induced currents unrelated to the cross product of B and V.
