ABSTRACT:
Each guide member of a fluidic oscillator has a diverter which acts to split the flow from the power nozzle into a control stream that is diverted toward the inlet of an associated feedback path and an output stream that is directed toward an output duct. The resultant fluidic forces exerted alternately on the diverters are sensed, and the sensor outputs are processed to generate a sinusoidal wave from which volumetric flow or mass flow output signals are derived.
