Abstract

Selon cette invention, un dispositif de surveillance de flux de fluide comprend un cylindre (4) possédant une entrée (1) et plusieurs sorties (16, 17, 18, 19); un piston (8) coulissant à l'intérieur du cylindre (4), en contact sensiblement étanche avec la surface interne de celui-ci; un système de sollicitation (10) pour solliciter le piston (8) et le mettre en position fermée, ce qui prévient l'écoulement des fluides vers les sorties (16, 17, 18, 19) lorsque la différence de pression dans le fluide entre l'entrée (1) et les sorties (16, 17, 18, 19) est sensiblement nulle tout en permettant au piston (8) de se mettre dans des positions différentes à l'intérieur du cylindre (4) pour que le fluide puisse s'écouler à travers un nombre croissant de sorties (16, 17, 18, 19) lorsque la pression aux sorties tombe de façon croissante en dessous de celle à la sortie; et un détecteur (12, 13, 14) destiné à détecter la position du piston (8) à l'intérieur du cylindre et, partant, l'existence d'un flux de fluide à travers le dispositif.
