Abstract
L'invention concerne un débitmètre, en particulier un débitmètre destiné à être raccordé à un conduit de fluide. Selon l'invention, le débitmètre (1) possède une entrée (2) et une sortie (3) lui permettant d'être raccordé à un conduit et comprenant des cylindres reliés entre eux (10, 20, 30). Chaque cylindre comporte une pluralité d'orifices (11-17, 21-27, 31-37) commandés par un piston (100, 200, 300) se déplaçant axialement à l'intérieur de chaque cylindre de telle sorte qu'à n'importe quel moment, l'entrée et la sortie soient en communication fluidique grâce à un passage de fluide défini par deux cylindres. L'invention est caractérisée en ce que trois cylindres (10, 20, 30) sont reliés entre eux.
