ABSTRACT:
A gas leak meter is directly attached to a valve box having a leaking valve therein. Based upon the rate of gas leakage, a decision can be made to delay or replace the leaking valve. The gas leak meter has a stopper that is placed into the valve box. The stopper has a rubber tube attached thereon and this tube leads to a gas collector which operates at atmospheric pressure. In a given period of time, the rate of gas leakage can be determined based upon the amount of gas collected.
