Abstract
A system for measuring an amount of liquid in an elastic bag, where there is formed in the lower area of the elastic bag a liquid opening for retrieving liquid from the elastic bag. The system includes push elements, which abut at opposite walls of the elastic bag and which are spaced apart from one another, a drive unit, which is configured to drive at least one push element, sensors, and a control unit. The sensors are configured to measure a liquid level of the liquid in the elastic bag. The control unit is configured to calculate an amount of liquid in the elastic bag on the basis of the liquid level and the distance between the push elements. The liquid level of the liquid in the elastic bag is changeable by reducing the distance between the push elements by means of the at least one drive unit.
