Japanese Patent JP3276373
Kind Code:
B2
Abstract:
A fluidic oscillator and a flow meter comprising a means (10, 14, 16) for forming an oscillating two-dimensional fluid jet, and an obstacle (22) having a main cavity (26) on which the oscillating jet impinges, and secondary cavities (34, 36) on either side of the main cavity (26) for making radial extension of the main vortices accompanying the oscillation of the jet dependent on the flow rate, enabling the speed or flow rate of a fluid flow to be measured.
