The Phocus3M from Ovarro combines specialist leak noise detection and versatile communications technology to create a fixed network of loggers to monitor leakage in your water network, complete with market-leading antenna technology that reduces Opex by limiting downtime. The logger samples pipeline noise at one-second intervals during each of three sample epochs during the night when background acoustic noise is lowest.
Potential leak areas are quickly determined using PrimeWeb, which interprets the acoustic leakage data and performs advanced data analytics to identify the location of leaks.

The logger samples pipeline noise at one-second intervals during each of the three sample epochs during the night when background noise is lowest. Statistical analysis is performed on each of the three epochs to determine the Leakage Confidence Factor LCF. The minimum leak noise is also measured, termed the Critical Noise Value. CNV is important as a measure of how close to the leak the logger is situated.
