  • Propane gas leak detection
    Patent number: 5269171
    Abstract: A propane gas leak detection method includes permanently installing a test adapter unit in a line between a propane gas service valve unit and a first regulator and an adapter fitting in a pressure gauge receptacle of the service valve unit, temporarily connecting a flowmeter to the adapters, closing the service valve unit to bypass gas through the flowmeter, observing the rate of gas flow on the flowmeter, and disconnecting the flowmeter from the adapters after the gas leak test. The invention provides variations in the test adapters for use with service valve units having differing types of fittings and receptacles available.
