Abstract
A fluidic oscillator and a flowmeter comprising means (10, 14, 16) for forming a two-dimensional fluid jet and an obstacle (22) having a main cavity (26) swept by the oscillating jet, and secondary cavities (34, 36) on either side of the main cavity (26) enabling the radial extension of main vortices accompanying the oscillation of the jet to be made dependent on flow conditions. Applicable to the measurement of the velocity or flow rate of flowing fluid.
