ABSTRACT:
A sensing element for measuring fluid flow comprising an elongated cylindrically-shaped support on which is disposed two resistive films having high TCR values. The support is symmetrical about a plane parallel with the direction of flow, and one of the resistive films is disposed on each side of that plane. The films are less than 10,000 A thick, thereby possessing a high ratio of surface area to thermal mass. These films are quickly cooled by pressure variations accompanying the generation of vortices in the fluid stream, and they are therefore capable of operating at high frequencies.
