(FR) DISPOSITIF ET PROCEDE DESTINES A LA DETECTION PAR VOIE ELECTROMAGNETIQUE D'UN DEBIT DE LIQUIDE
Abstract
(EN)
An apparatus for sensing liquid flow rate comprises a conduit (50) for conducting a flow of liquid through it and a flow sensor. The flow sensor includes a fixed portion (56) attached to a sidewall of the conduit. The fixed portion has a pair of stationary electrodes (68 and 70) positioned in spaced apart relation and adapted to contact the liquid conducted through the conduit. The flow sensor further includes a cartridge portion (82) adapted for removable engagement with the fixed portion. The cartridge portion has sensor terminals (104, 106) adapted to electrically engage the stationary electrodes. In addition, the flow sensor includes an electromagnetic coil (122) operative to generate a magnetic field within the fluid flow.

L'invention concerne un dispositif destiné à la détection d'un débit de liquide, comprenant un conduit par lequel peut s'écouler un liquide et un détecteur de débit. Le détecteur de débit comporte une partie fixe rattachée à une paroi latérale du conduit. Cette partie fixe comprend une paire d'électrodes fixes, espacées l'une par rapport à l'autre, conçues pour entrer en contact avec le liquide traversant le conduit. Le détecteur de débit comprend également une cartouche conçue pour entrer en prise de manière amovible avec la partie fixe. Cette cartouche comporte des bornes de capteur conçues pour être connectées aux électrodes fixes. De plus, le détecteur de débit comprend une bobine électromagnétique pouvant produire un champ magnétique dans le débit de liquide.
