Abstract
Appareil pour déterminer la caractéristique d'un débitmètre. L'appareil comporte un cylindre 17 destiné à être monté dans un circuit fluidique en série avec le débitmètre dont la caractéristique doit être déterminée, ce cylindre contenant un piston 30, 31 traversé par un passage 52 obturé par une soupape 37 raccordée par une tige 38 à un piston auxlilaire 64 dont le déplacement est commandé par un circuit pneumatique 75-81. Au début d'une mesure, le piston 30, 31 est en amont du cylindre 17 et la soupape 37 est ouverte. On actionne le circuit pneumatique 75-81 pour déplacer le piston auxiliaire vers l'aval de façon qu'il ferme la soupape puis suive le piston 30, 31 entraîné par le fluide jusqu'à l'extrémité aval du cylindre où le piston auxiliaire rouvre la soupape. On actionne ensuite le circuit pneumatique pour ramener les organes à leur position initiale. Des détecteurs 65, 66 mesurent la vitesse du piston 64 et, de ce fait, le débit volumique du circuit fluidique. Application notamment aux contrôleurs de débitmètre montés à demeure.
