Abstract: An implementation is for a two-phase shutoff of a device having a sensor coupled to an integral shutoff system. One example includes a metering system with a sensor coupled to an integral shutoff system, wherein the sensor is used to perform a measurement which indicates that a first threshold has been met, a first response system configured to perform at least one action with respect to receiving the indication that the first threshold was met, the at least one action occurring while the integral shutoff system remains inactivated, a second response system configured to receive an indication from the metering system, wherein the sensor is used to perform a second measurement which indicates that a second threshold has been met, and a second response system configured to perform at least one additional action.

Abstract: A method includes attaching a gas capture device to a bypass system adjacent to a gas meter. The method also includes rotating an internal cartridge near the gas meter to a bypass mode. The rotation of the internal cartridge enables gas to be diverted through a bypass system and away from the gas meter into an outlet. Remaining gas is captured from the gas meter to prevent the gas from releasing externally. The gas meter is removed from its original position. The internal cartridge is rotated from the bypass mode to a purge mode.
