A fast and easy way to determine if a CO2 gas leak is present. Ideal when dispensing multiple kegs.
How it works
There is a chamber that contains a small plastic float. If gas flows through the chamber the float lifts up. The larger the gas flow the higher the float lifts up. If no beer is being poured the float should remain at the bottom of the chamber. If it is floating, with no beer being poured a leak is present.
