Abstract
A fluidic oscillator symmetrical with respect to a longitudinal plane of symmetry (P) in which the longitudinal direction of a fluid flow lies. Said oscillator includes a component (26b) for generating a two-dimensional fluid jet oscillating transversely to said longitudinal plane of symmetry (P); two ultrasonic transducers (52, 54); components (62-72) for outputting an ultrasonic signal from one transducer through the fluid flow towards the other transducer, and receiving the ultrasonic signal modulated by the oscillation of the fluid jet; and components (100) for processing the received signal to determine the volume of fluid that has flowed through said fluidic oscillator, said ultrasonic transducers (52, 54) being substantially in alignment along the longitudinal plane of symmetry (P).
