Abstract

L'INVENTION CONCERNE UN APPAREIL MESUREUR D'ECOULEMENT DESTINE A UN SYSTEME D'INJECTION DE FLUIDES. IL COMPORTE UN DISPOSITIF DE COMMANDE QUI PERMET DE PREREGLER LE VOLUME ET LE DEBIT DU FLUIDE A INJECTER ET D'ASSURER UNE FONCTION D'ALARME EN CAS DE MAUVAIS FONCTIONNEMENT DE LA POMPE OU D'OCCLUSION DE LA TUBULURE DU NECESSAIRE A INJECTION, UN CIRCUIT ELECTRONIQUE D'ALIMENTATION MONTE DANS LE DISPOSITIF DE COMMANDE LE RENDANT INSENSIBLE AUX TRANSITOIRES DU RESEAU D'ALIMENTATION, TANDIS QU'UN DETECTEUR DE BULLES ASSURE UNE DETECTION PLUS SURE DES BULLES D'AIR DANS LA TUBULURE. PAR AILLEURS UNE TRINGLERIE MECANIQUE ENTRE LA PLAQUE PRESSEUSE ET UN PLONGEUR DE RETENUE DE L'ECOULEMENT EN AVAL DANS L'APPAREIL DE MESURE ASSURE LA CHARGE APPROPRIEE DU NECESSAIRE A INJECTION ET LA FERMETURE AUTOMATIQUE DU PLONGEUR AVANT L'EMPLOI. APPLICATION NOTAMMENT AUX APPAREILS D'INJECTION DU TYPE A POMPE PERISTALTIQUE.THE INVENTION RELATES TO A FLOW MEASURING APPARATUS INTENDED FOR A FLUID INJECTION SYSTEM. IT INCLUDES A CONTROL DEVICE THAT ALLOWS THE VOLUME AND FLOW OF THE FLUID TO BE INJECTED TO BE PRE-SETTED AND TO PROVIDE AN ALARM FUNCTION IN THE EVENT OF MALFUNCTIONING OF THE PUMP OR OF THE TUBING OF THE INJECTION NECESSARY, A CIRCUIT POWER SUPPLY ELECTRONICS MOUNTED IN THE CONTROL UNIT MAKING IT INSENSITIVE TO THE TRANSITORIES OF THE POWER SUPPLY NETWORK, WHILE A BUBBLE DETECTOR PROVIDES A SAFER DETECTION OF AIR BUBBLES IN THE TUBING. ALSO A MECHANICAL LINKAGE BETWEEN THE PRESSER PLATE AND A DOWNSTREAM FLOW RETAINING PLUNGER IN THE MEASURING DEVICE ENSURES THE APPROPRIATE LOAD OF THE INJECTION KIT AND THE AUTOMATIC CLOSING OF THE PLUNGER BEFORE USE. APPLICATION ESPECIALLY TO INJECTION DEVICES OF THE PERISTALTIC PUMP TYPE.
