A computer (28) controlled metering pump. The displacement of a metering pump (10) is accurately monitored using a position sensor (13) connected to a piston. A control computer (28) receives the sensor signal as well as a desired pumping volume rate (119). The pumped volume is continuously monitored by the computer as a function of the piston displacement, and compared with the desired rate (119). The metering pump (10) is controlled to bring the pumped volume rate into agreement with the desired volumetric pumping rate.

Pompe de dosage commandée par ordinateur (28). Le déplacement d'une pompe de dosage (10) est contrôlée avec précision au moyen d'un palpeur de position (13) connecté à un piston. Un ordinateur de commande (28) reçoit le signal du palpeur ainsi qu'un débit de volume pompé souhaité (119). Le volume pompé est contrôlé en continu par l'ordinateur en tant que fonction du déplacement du piston, et comparé au débit souhaité (119). La pompe de dosage (10) est commandée de manière à faire correspondre le débit du volume pompé avec le débit de pompage volumétrique souhaité.
