Abstract
A sensor for use in a vortex flow meter which is capable of measuring various physical characteristics of a flow in a single process penetration from a common source. A shedder bar in the vortex meter generates alternating vortices. The sensor is located in the shedder bar within the stream of the fluid flow. The shedder bar serves as a composite vortex-generating plate and sensing unit. The shedder bar is structured such that it is either removable from the flow pipe for calibration, replacement, cleaning and the like or is permanently welded into the flow pipe with smooth or rigid contact surfaces. The sensor comprises one or more sensing diaphragms containing piezoresistor elements arranged in a Wheatstone bridge configuration. The sensor produces electric signals indicative of flow velocity, fluid pressure, and temperature. These signals are transmitted to a processing element which computes additional flow parameters.
