Abstract
Methods of determining if it is safe to restore service to a gas meter remotely are provided. The method includes determining if any pre-existing conditions are present in the gas meter responsive to issuance of a restore command to restore service from a remote location. The pre-existing conditions indicates that safety test results are unreliable. If it is determined that no pre-existing conditions are present, a valve on the gas meter is opened to fill the gas meter with gas until the gas meter reaches a predefined fill state. It is determined if pressure in the gas meter is stable at the predefined fill state and the valve on the gas meter is closed if the pressure is stabilized. A pressure decay test is performed after the valve on the gas meter is closed. The valve to restore gas flow is opened if the pressure decay test passes.
