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.
