A fluidic oscillator flowmeter employs a fluidic oscillator wherein the frequency is proportional to flow through the oscillator. The oscillating flow is divided into two discrete paths, facilitating the counting of the frequency and the transduction of the frequency into a flow measurement indication. In one embodiment the flowmeter may be inserted into a large flow stream, wherein it utilizes only a small portion of the measured flow and presents a streamlined profile to the flow to minimize pressure losses. Alternatively, the entire measured flow may be passed through the flowmeter.
