Abstract
A robust pipeline leak detection system allows the operator to take timely corrective action to the problem, minimizing leakage of the fluids contained in the pipeline to the environment. The wireless sensor network system disclosed in this invention detects the presence of a leak by various sensors including acoustic sensors distributed along a pipeline system. The sensors are connected to the wireless sensor network. An advantage of this system is that it is possible to deploy the leak detection system on existing buried pipelines without significant excavation.
