Abstract: A fluid velocity meter having an elongate body defining a flow opening therein bounded by an inner top wall, inner bottom wall, and a pair of side walls with the flow opening extending completely through the elongate body to allow a stream of fluid to pass through the flow opening. A vortex-generating element is provided within the flow opening to direct vortices to impinge on the inner top and bottom walls in an alternate fashion. First and second sensors are disposed within the elongate body and positioned adjacent to the inner top and bottom walls. Output means are provided for generating a signal indicative of the force supplied to each sensor, and thus the velocity of the flowing fluid can be determined.

Abstract: A vortex-shedding flowmeter having two independent force sensors disposed on opposite sides of a tailpiece downstream from the vortex generating element for detecting fluid pressures. The signals derived from the two sensors are merged to form a composite output signal so as to cancel spurious signals caused by fluid pulsations or noise. One or both sensors may be provided with an adjustable gain element to compensate for differences in sensitivity.
