Abstract

Le système (8) a pour objet de peser des liquides provenant de plusieurs sources (76) et de réguler leur flux dans un circuit d'écoulement (10). Selon ce système, le liquide admis est recueilli dans une poche de pesée (80) associée à un dispositif permettant de contrôler la quantité de liquide qui traverse cette poche (80) et empêchant toute entrée d'air dans le circuit (10). Une alarme, associée à la poche (80), signale quand celle-ci est sur le point d'être vide, de manière qu'elle puisse être à nouveau remplie depuis la source (76) avant que son contenu ne soit totalement épuisé. Si la poche (80) n'est pas réalimentée, le système s'arrête automatiquement. La pompe à liquide (72) peut être étalonnée de manière absolue par régulation du débit de quantités connues de liquides dans la poche (80), de manière à pouvoir calculer automatiquement la quantité de liquide introduite dans le circuit d'écoulement (10).
