Abstract
A method and apparatus for removal of free gas (e.g., air) from liquid flowing under pressure through piping. The invention is particularly useful when the flow is being measured by a meter of the turbine or positive displacement types. A closed pressure tank is connected in the flow piping and is provided with means for controlled venting of air from the upper tank portion. Preferably the flow of liquid is interrupted when the volume of air in the tank becomes excessive, and the flow is restored after sufficient gas has been vented from the tank to ensure normal operation.
