The wetting pressure of a carbonation stone is the PSI required for gas to come through the very small pores of the stone. This number is usually added to the PSI that you can want to carbonate your beer to. Oxygen flow meters such as the one blichmann offers has a dial at the end of the meter where one sets the flow rate (1 liter/min as an example). Has anyone found that wetting pressure correlates with the allowance of oxygen to even flow through the stone? For example: if one were to dial the flow meter back to 0.2 l/min would gas even flow out as wetting pressure is impeding this? If its 0.4 l/min setting that counteracts the wetting pressure should this be added to what you dial your flow rate to? Example: if i choose to want 1l/min flow I know dial my flow meter to 1.4 L/min to account wetting pressure?
