Abstract

L'invention concerne la mesure du débit des fluides. Elle a pour objet un débitmètre comportant deux chambres, pour l'arrivée et la sortie du fluide, séparées par une membrane élastique, celle-ci étant percée d'un orifice qui fait communiquer les deux chambres et dont la section peut être réglée par un pointeau, la déformation de la membrane sous l'action du débit de fluide, se transmettant à un appareil de lecture par des moyens électriques, électromécaniques ou purement mécaniques. Ce débitmètre peut être utilisé avantageusement pour la mesure de la consommation en carburant des véhicules, pendant la marche de ces derniers.
