The invention relates to a method for determining a volume of carbonated beverage being included in a collapsible beverage container, said method comprising the step of providing a beverage dispensing system, including a pressure chamber in which said collapsible container is included, said pressure chamber defining an inner volume being equal to the sum of said volume of beverage and a residual gas volume, a pressurizarion system for supplying a volume of gas of atmospheric pressure from the outside of the pressure chamber to said residual gas volume, and a pressure sensor for detecting a low pressure value and a high pressure value, respectively, in said inner volume, the low pressure value being higher than atmospheric pressure, and the high pressure value being higher than said low pressure value, said method further comprising the steps of supplying said volume of gas to the residual gas volume by using the pressurization system in response to detecting the low pressure value of the inner volume and raising the pressure in the inner volume from said low pressure value to said high pressure value, determining the volume of gas supplied by the pressurization system from the outside of the pressure chamber to the residual gas volume in between detecting the low pressure value in the inner volume and detecting the high pressure value in the inner volume, and establishing a measure of the volume of beverage included in the collapsible beverage container, said measure being based on said gas volume, said inner volume, said low pressure value and said high pressure value. Furthermore, the invention relates to a corresponding beverage dispensing system wherein the volume of beverage is defined by the method stated above. |
