Abstract:
An automatically actuated regulation system for gas and other fluids flowing in a pipeline comprising:a microprocessor configured to control said regulation system; a flow control unit coupled to said microprocessor, said flow control unit configured to regulate the flow through said pipeline when activated; a vibration sensor coupled to said microprocessor, said sensor configured to determine seismic activity of the earth in the vicinity of said system, and generate a vibration indication signal corresponding to the amplitude of said seismic activity; a mechanical gas flow meter configured to provide a mechanical indication of the measure of gas flow through said pipeline; a conversion means converting said mechanical indication to an electrical output signal, said means coupled to said microprocessor; a trigger unit, said trigger unit coupled to said flow control unit and configured to activate said flow control unit; and said trigger unit activating said flow control unit when said vibration indication signal is larger than a first predetermined threshold value, and said measure of flow signal is larger than a second threshold value.
