ABSTRACT:
The invention utilizes a conduit, having an input, an output, and a central region therebetween, in conjunction with a nozzle having an inlet, a restricted outlet and a thin-wall throughput region, to measure fluid flow. The nozzle inlet sealingly cooperates with the conduit, and the nozzle throughput region and restricted outlet project into the conduit central region, thereby allowing fluid in the conduit central region to surround the nozzle. The nozzle throughput region elastically deforms circumaxially and longitudinally proportional to varying fluid flow. Sensor means are provided to measure and evaluate the elastic deformation caused by fluid flow and to provide a pressure deformation signal from which fluid flow may be determined. The nozzle is interchangeable to allow nozzles of specified construction and characteristics to be utilized as needed.
