A flow meter having a fluidic oscillator in which a two-dimensional fluid jet oscillating transversely relative to a plane of symmetry (P) impinges on the back of a cavity (24). The flow rate of said jet is subtracted by electronic means (42, 44) from a signal (S) which corresponds to a differential pressure resulting from the difference between a pressure sensed at a point (P3) on the axis of intersection of the plane of symmetry with the back of the cavity (24), and a differential pressure resulting from pressure sensing at two points (P1, P2) symmetrically located on either side of the plane of symmetry.
