Abstract:
A method for providing data to a plurality of authorized users which comprises:maintaining a database of premises having automated shut-off actuator systems; receiving shut-off indication signals from said premises having automated shut-off actuator systems, wherein said shut-off indication signal is initiated by measuring gas flow in a pipeline; measuring vibration in the vicinity of said pipeline, and providing a vibration indication signal; measuring gas flow after it is determined that value of said vibration indication signal exceeds a first predetermined threshold; comparing gas flow, before value of said vibration indication signal exceeds said first predetermined threshold, to gas flow, after value of said vibration indication signal exceeds said first predetermined threshold; and stopping the flow of gas when the gas flow, after value of said vibration indication signal exceeds said first predetermined threshold, exceeds a second threshold; updating said database with information that a shut-off indication has been received by said automated shut-off actuator system; and providing said information to authorized users.
