ABSTRACT:
A fluidic oscillator flowmeter in which a two-dimensional fluid jet oscillating transfersely relative to a plane of symmetry, P, sweeps over the bottom of a cavity, and in which the flow rate is determined by electronic means from a signal, S, corresponding to a differential pressure resulting from the difference between a pressure tapped off at a point, P.sub.3, located on the axis of intersection between the plane of symmetry, S, and the bottom of the cavity and a pressure resulting from tapping off the pressure at two points, P.sub.1 and P.sub.2, which are located symmetrically on respective sides of the plane of symmetry, S.
