Patent

CA 2439493

The invention concerns bubble level meter having a pneumatic tube (2) connected to a gas generator (12) and to a pressure sensor (14). A deflecting valve (16) is interposed along the pneumatic tube, for deflecting the air outlet at a predetermined height from the usual lower outlet (8) of the tube. A control circuit (20) controls the deflecting valve and the gas generator based on predetermined set values, processes the pressure measurements obtained from the pressure sensor, checks the calibration of the sensor on the basis of the measurements and the difference in height between the tube outlets, and generates level data based on the processed pressure measurements and a calibrating coefficient. Another valve (28) interposed between the sensor (14) and the tube (2) and monitored by the circuit control (20), enables to take into account the possible drift of the sensor. FIG. 1: 52 KEYBOARD 46 DISPLAY 20 CONTROL CIRCUIT 12 GAS GENERATOR 14 PRESSURE SENSOR

Un limnimètre à bulles ayant un tube pneumatique (2) relié à un générateur de gaz (12) et à un capteur de pression (14). Une valve de déviation (16) est interposée le long du tube pneumatique, permettant de dévier la sortie d'air à une hauteur prédéterminée de la sortie inférieure habituelle (8) du tube. Un circuit de contrôle (20) commande la valve de déviation et le générateur de gaz en fonction de consignes préréglées, traite les mesures de pression obtenues du capteur de pression, vérifie l'étalonnage du capteur en fonction des mesures et de la différence de hauteur entre les sorties du tube, et génère des données de niveau en fonction des mesures de pression traitées et du coefficient d'étalonage. Une autre valve (28) interposée entre le capteur (14) et le tube (2) et sous contrôle du circuit de contrôle (20), permet de considérer la dérive possible du capteur.
