1. A two-phase shutoff system, comprising:
a metering system with a sensor coupled to an integral shutoff system, wherein the sensor is used to perform a measurement which indicates a first threshold has been met;
a first response system configured to perform at least one action with respect to receiving the indication the first threshold was met, the first threshold indicates a lower of two thresholds, the at least one action occurring while the integral shutoff system remains inactivated to allow the two-phase shutoff system to correct any abnormality without shutting off the line;
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 a second threshold has been met, the second threshold indicates a higher threshold of the two thresholds; and
the second response system configured to perform at least one additional action, wherein the at least one additional action includes activating the integral shutoff system.
