Advanced digital and electro-acoustic technology for Water Leak Technicians, Plumbers and Damage Restoration Engineers to locate water leaks. Correlators, Ground mics, Tracer gas, Noise loggers.
Locating and tracing plastic & non-metallic pipes using electro-acoustics. Locating metallic pipes and cables using electromagnetic fields (signal generators-Genny). Pipe and cable locators & tracers. Finding lost manhole covers and spindles with Sewerin metal detectors.
Instruments for locating, tracing, warning of gas leaks in distribution networks, houses and the work place.
Portable and fixed systems to monitor Biogas, Anaerobic Digesters, CHP plants and landfill gas composition.
Techniques for finding water leaks:
Correlators: Two microphones are attached to a water pipe with a leak and both “listen” for the noise from the water leak. If they can both “hear” the water leak, the correlator (combined with other data entered by the user) calculates the position of the water leak. Correlation is best suited to larger pipe networks such as network distribution pipes.
Ground microphones: Leaking pressurised water pipes produce noise. Using electroacoustic ground microphones, or listening sticks, the resulting water leak noise can be heard and the water leak location identified. This technique works well both indoors and outdoors.
Hydrogen Tracer Gas: A tracer gas containing hydrogen and nitrogen is introduced into the water pipe with the suspected leak. The gas escapes from the leak point and is detected by the Variotec 460 Tracer gas instrument. Very successful leak detection method inside buildings, on customer supply pipes & swimming pool water leaks.
Pipe Location: To locate a water leak you first need to know where the pipe is. Using Sewerin pipe Location Tools you can find & trace both metallic pipes & cables and locate plastic pipes outdoors.
