Abstract
La présente invention concerne des systèmes et procédés de pompage de fluides au moyen d'une pompe. La pompe comprend une chambre de pompe (PPN) qui réagit à l'application de pression par un entraînement du fluide. Les systèmes et les procédés assurent la mise en oeuvre de mesures de régulation par le régulateur (16) de façon à surveiller l'écoulement de fluide dans la pompe, soit par détection gravimétrique (246), soit par détection de champs électriques.
