I kegged a beer on Saturday and my CO2 tank was reading in the green area on the gauge. I checked all connections with Star San from a spray bottle and no leaks. My pressure was set at 11 psi for the newly kegged beer and 1 other connected to the CO2 but that was fully carbonated before.
Last night I check the tank and the gauge is in the red zone stating it is almost empty. I checked again for leaks and didn't find any. I turned the pressure up a little and can still hear gas flowing, then turned it back down to 11 psi. My tank sits in my kegerator with the kegs at 40F.
Do the gauges read incorrectly if they are in the kegerator because of the cold? I can't believe this tank went from green to red in 4 days when I can't find a leak.
Also, is there a good way to tell if a tank is empty? It is a 5lb, aluminum tank.
