Network Monitoring Noise Loggers are used for early detection of leaks in water supply networks.The longer it takes to identify that a network is leaking the more revenue is lost and the greater the loss of precious water resources.
In addition to the more conventional methods of leak detection the installation of permanent noise loggers has proved to be a cost effective tool in early identification of water loss. By permanently monitoring sections of the system, which have previously been proven leak free, it will alert you when a potential leak does develop. Using a network of Noise Loggers, digital Correlating Loggers (DCLs), Leak Detection Specialists Ltd can pinpoint the exact locations of any leaks in one overnight surveillance. Our engineers will plan the placement of the DCLs and analyze and review the overnight results.
Noise loggers are considerably more sensitive than the human ear and are usually active during the night, when background noise is at a minimum. Noise amplitude will vary due to random effects, but there will always be a consistent minimum due to any noise that is always present i.e. leakage. Noise generated by a leak tends to have reasonably consistent amplitude. The small devices are deployed at points around the water network, where we will monitor the noise levels on the pipes themselves. Changes and distinctive patterns in sound indicate the presence of leaks, often including ones that would otherwise go completely undetected. Data is collected from all DCLs pinpointing the map locations of any leak sounds present. Our LDS engineers will identify the recorded noise at different locations to determine the location of the leak.
Leak noise loggers help to reduce leakage levels and operating costs simultaneously by monitoring large areas of the water network quickly and effectively. The results will enable water suppliers to reduce leakage cost effectively and to maintain these low levels at minimal cost.
LDS engineers have successfully used Noise Loggers at Holiday Parks, Aviation sites, Parks, Schools, Prisons and other commercial and industrial premises.
