Abstract

L'invention concerne un capteur de pression active pour débitmètre, qui est particulièrement adapté aux tuyaux de grand diamètre. Ce capteur comprend un corps (1) que l'on branche sur une conduite et auquel est intégré un élément (8) générateur de pression active. Ce dernier consiste en au moins un canal étroit (9), circulaire et de type fente à travers lequel s'écoule un flux réduit prélevé sur le courant général. On mesure la chute de pression dudit flux afin de déterminer le débit total. La section transversale du canal (ou des canaux) circulaires peut être constante ou variable.
