Abstract
A method for determining a volume of beverage, preferably a carbonated beverage in a collapsible beverage container, comprises a beverage dispensing system including a pressure chamber with the collapsible container, the pressure chamber defining an inner volume equal to the sum of the volume of beverage and a residual gas volume. The method also comprises a pressurization system for supplying a volume of gas of atmospheric pressure from the outside of the pressure chamber to the residual gas volume, and a pressure sensor for detecting a low pressure value and a high pressure value, respectively. The method further comprises the steps of supplying the volume of gas to the residual gas volume by using the pressurization system, determining the volume of gas supplied by the pressurization system from the outside of the pressure chamber to the residual gas volume, and establishing a measure of the volume of beverage included in the collapsible beverage container.
