ABSTRACT:
An automatically actuated regulation system for a natural gas pipeline having flow control unit, a vibration sensor, a gas flow meter, a trigger unit, and a microprocessor. The microprocessor actuates the flow control unit when two conditions are met. First, there must be a vibration which surpasses a predetermined threshold. Second, flow in the natural gas pipeline must have increased over the flow rate before the vibration.
