ABSTRACT:
An apparatus measures the flow rate of a fluid. The apparatus comprises a fluidic oscillator provided with an elongate slot in a direction Oz and suitable for forming a jet of fluid that oscillates in a plane Oxy perpendicular to the Oz direction, and an obstacle located upstream from the slot to modify the distribution of speeds in the flow. The obstacle is in the flow at least in the central portion thereof and is implemented in the form of a substantially plane plate.
