Abstract

Appareil de mesure de débit, comportant un conduit d'écoulement 20 avec barre transversale de rejet de tourbillons 22 et moyens ultrasonores 23, 25 pour déceler le passage des tourbillons de Karman rejetés par la barre lorsque le fluide passe au niveau de cette barre, le signal de sortie alternatif des moyens de détection étant transformé en signal d'onde rectangulaire apte à la commande d'un compteur numérique. Un ou plusieurs organes transversaux supplémentaires 30 sont placés en aval des moyens de détection, perpendiculairement à la barre de rejet de tourbillons; ils presentent une section cylindrique, ou en forme d'aile, ou rectangulaire, ou de toute autre forme avec face plate aval parallèle à la barre. Application notamment à la mesure de la vitesse d'un écoulement d'air.
