While there are many ways available for water leak detection of buried water pipes, Acoustic leak detection method remains the first choice for detecting and locating pipeline leaks. In Acoustic Leak Detection Method, the underground water leak detector identifies the leakage sound with the help of listening equipment & pinpoint the exact locations of water leaks in buried water pipes laid in cities, towns, industrial & residential areas.
The leakage sound consists of four sounds: water flow sound, impact sound, friction sound & vibration sound. The closer an operator gets to the leak point, the intensity/strength of the signal will increase. The underground leak detection system detects the leakage sound & by figuring out the highest sound intensity & pinpoints the exact damaged location.
Stanlay offers latest generation PERIJA PLUS smart acoustic water pipe leak detection equipment, based on a piezo electric ground microphone coupled with an advanced controller for identifying leaks in all types of pressurized buried water pipe networks, metallic and non-metallic water pipe networks, in both the main lines and branches of metro, industrial and irrigation environment for pipe sizes upto 750mm.
