A flowmeter measuring chamber having a generally cylindrical outer wall, a generally cylindrical inner wall, and a piston, having a tubular wall disposed between the inner and outer walls and arranged to oscillate within the outer wall, is provided with a mechanism for controlling movement of the tubular wall. That movement is controlled so that a capillary space is maintained between the tubular wall and the inner wall and between the tubular wall and the outer wall at all positions of the piston and contact between the tubular wall and the inner and outer walls is prevented.
La présente invention porte sur un jaugeur de débitmètre comportant une paroi externe généralement cylindrique, une paroi interne généralement cylindrique ainsi qu'un piston présentant une paroi tubulaire placée entre les parois interne et externe et configurée de manière à osciller à l'intérieur de la paroi externe. Le dispositif comprend un mécanisme destiné à contrôler le mouvement de la paroi tubulaire de manière à maintenir un espace capillaire entre la paroi tubulaire et la paroi interne ainsi qu'entre la paroi tubulaire et la paroi externe, peu importe la position du piston, et ainsi empêcher que la paroi tubulaire ne vienne en contact avec les parois interne et externe.
