Abstract

L'invention concerne l'industrie des appareils de mesure de debit. Détecteur d'écoulement massique comportant une conduite 26 dans laquelle circule l'écoulement massique de fluide qui doit être détecté; un corps 28, formant obstacle disposé dans ladite conduite pour produire des tourbillons périodiques, ledit corps et ladite conduite définissant entre eux une section d'écoulement A, ledit corps possédant une dimension caractéristique d suivant une direction sensiblement perpendiculaire à la direction de l'écoulement massique dans la conduite et la fréquence des tourbillons étant fonction du produit A x d; des moyens 50 pour régler le produit A x d en fonction de la densité de l'écoulement massique, ladite fréquence étant de ce fait représentative de l'écoulement massique; et des moyens 30, 32 pour détecter ladite fréquence. Application notamment à la détermination du débit massique d'un liquide ou d'un gaz.
