METHOD AND SYSTEM FOR DETECTING A LEAK OF FLUID FROM A FLUID-CARRYING DUCT

摘要

A method and a system for the detection of leaked fluid that leaked out of a fluid-carrying duct associated with at least one optical conductor. The method and the system monitor an aboveground portion of the duct along which the optical conductor runs. The mechanical mechanism includes a leaked-fluid collector configured to collect the leaked fluid, a leak-operated device configured to respond to the leaked fluid, and a strain application structure configured to use the leak-operated device to apply a strain deformation on the at least one optical conductor. The monitored leaks include leaks of liquid and leaks of pressurized gas. The leak-operated device is buoyant on the leaked fluid, or is a substance that expands in liquid, or is a hermetically sealed chamber.

1. A method for detecting a leak of fluid out of a fluid-carrying duct operating in association with at least one optical conductor, the method comprising the steps of:
providing a leaked-fluid collector for collecting fluid leaking out of the duct, providing a leak-operated device responding to fluid that leaked out of the duct, and providing a strain application structure using the leak-operated device for applying strain deformation on the at least one optical conductor.
