Abstract

Pompe permettant de régler le débit en fonction des caractéristiques du liquide et des canalisations. Elle comporte un tube calibré délimité par deux capteurs optoélectroniques et dont le temps de remplissage variable permet d'étalonner le débit d'une façon automatique en agissant sur la fréquence d'une horloge électronique. Application de la technique des impulsions aux pompes notamment aux pompes à usage médical.
