We identify leak through advanced acoustic listening techniques. As liquid escapes from a pressurized pipeline, an acoustic leak noise is generated, which travels along the entire length of the pipe. This noise can be efficiently captured by using an electronic listening stick, geophone or acoustic leak noise accelerometer.
Using correlators at different points along the pipeline to detects sound or vibrations caused by the leaks. Audio post processing (gain & filtration) is performed on the detected signal audio file. This process involved the measurement and comparison of the audio files captured simultaneously at different points. Hence, we can accurately identify the location of the leak.
For non-metallic pipe or leak confirmation, we utilize in-line CCTV and/or hydrophone. These tools introduced into the pressurized pipeline without disrupting service, allowing us to visually inspect and acoustically detect the exact location of the leak.
