ABSTRACT:
An electrical flowmeter having signal electrodes laterally spaced along a line perpendicular to fluid flow and sensitive to a voltage field set up in the fluid by a magnetic field is provided with helically coiled conductive windings disposed in a laminar arrangement in a plane parallel to the direction of fluid flow and wound in a helical spiral and connected to receive alternating current. The signal electrodes are spaced proximate to the outer coil windings, and a neutral electrode is provided at the helical vertex of the windings. The electrical field set up in the fluid impresses a voltage field across the signal electrodes proportional to relative fluid velocity and immune from quandrature and hydrodynamic effects. The laminar arrangement of the flowmeter electrode and electromagnetic conductive windings allows a flowmeter to be affixed to the exterior of the hull of a marine vessel, to be molded into the structure of the hull of a marine vessel, or to be positioned on the floor or wall of fluid conduit without creating turbulence in fluid flow.
