What are they?
Leak noise loggers help to reduce leakage levels and operating costs simultaneously by monitoring large areas of the water network quickly and effectively. They have become a standard piece of equipment for leak detection, and enables water suppliers to reduce leakage cost effectively, and to maintain these low levels at a minimal cost. Noise loggers are considerably more sensitive than the human ear and are usually active during the night when background noise is at a minimum.
Leak loggers take leak detection and locating to the next step by being able to log leak sound without a utility worker present, which could be at night, on weekends. Logging can also be used to take repeated leak noise recordings over time to determine if a leak is growing, developing, or to rule out short term usage that could be falsely detected as a leak. Leak loggers can record leak sound at a single location like a simple leak detector. Leak correlators that can be set to log and correlate at the same time can also be used.
