Abstract

L'invention se rapporte à un capteur de pression active pour débitmètre, destiné en particulier aux tuyaux de grand diamètre et comprenant un corps (1) branché sur un pipeline et auquel est intégré un élément (8) générateur de pression active; ce dernier comporte une cannelure (9) en forme de fente de profondeur variable, qui passe par la génératrice. En son point le plus profond, la cannelure communique avec un raccord (7) pour permettre la prise de la pression maximale. On calcule le débit du flux par unité de temps sur la base de la différence entre la valeur de pression relevée audit point et celle relevée en un point situé sur un deuxième raccord, installé en aval.
