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. The system can be configured to store gas usage data and, in one embodiment, transmit the data to another location through the use of a modem or other communication means.
