Correlation processing noise water leaks from the pipeline is used to detect leaks in pipelines with excess internal pressure leak detection fluid. Movement of fluid leakage pressure change generates fast around the site of the leak, resulting in place of diversion occurs a noise source. Such noise is distributed with constant speed along the pipes in both directions from the leak and is used to determine the location of the leak.
