Abstract
An apparatus and method for notifying a user of a pending empty gas supply tank. The user can input the initial volume of the gas supply tank, a gas monitor can monitor the amount of gas that was injected into the chamber and an indicator can notify the user when the gas volume of the supply tank is at or below a predetermined level so that the user can take the appropriate action. Additionally, a gas volume converter can be included to convert from one volume unit to another.
