METHOD AND DEVICE OF DETECTING THE OPERATIONAL MODE OF A BEVERAGE SYSTEM

摘要

The present invention relates to a method of detecting the operational mode of a beverage dispensing system, which comprises a sealable pressure chamber (10) to be shifted between a first open position and a second closed position, a collapsible keg (168) to be received within the sealable pressure chamber, a tapping line (68), at least during use connected to the collapsible keg, and a fluid pressure source (112) connected to the pressure chamber for pressurising the pressure chamber. The beverage dispensing system further comprises a first detector having a pressure input and a control pressure output and a second detector having a pressure input and a control pressure output. The method comprises evaluating as a logical AND the control pressures from the control pressure outputs of the detectors and determining the operational mode of the beverage dispensing system.
