Abstract

L'invention concerne un appareil exécutant des mesures dans un circuit dérivé d'une conduite 2. Elle est caractérisée par la combinaison : a) d'une dérivation permanente 3, 8, 6, 10, 25, 27, 4 provoquée par un étranglement 5, b) d'un appareillage 7, 9 pouvant interrompre les circulations du fluide dans l'appareillage et provoquer la chute d'un piston 13 déterminant le passage d'un volume donné de fluide dans un tube calibré 25, c) l'appréciation du temps d'écoulement de ce liquide par des capteurs 20, 21 entre deux passages du piston 13 agissant en liaison avec la minuterie 24. Application à la mesure de viscosité d'une conduite d'alimentation d'un brûleur notamment.
