Abstract

L'invention concerne une unité formant sonde pour un appareil de mesure d'un débit de fluide, comprenant un corps générateur de tourbillons se trouvant à travers le courant du fluide, sensiblement à angle droit par rapport à sa direction d'écoulement, ce corps comportant une fente le traversant sensiblement perpendiculairement à la direction d'écoulement du fluide, et un moyen transducteur sensible à des variations des conditions hydrodynamiques dans la fente pour convertir ces variations hydrodynamiques en variations d'un paramètre électrique du moyen transducteur quand le corps est placé dans le courant du fluide. Selon l'invention, la section médiane 38 de la fente 36 est plus étroite que d'autres sections de cette fente. L'invention s'applique notamment à la mesure du débit d'air, entre autres pour un moteur à combustion interne.
