Flow Metrix´s Digital Correlating Loggers

give breakthrough price / performance in detecting and pinpointing leaks over several miles of water distribution system pipe. Their patented technology makes highly synchronized sound recordings overnight from valves. After daytime retrieval of the loggers, Flow Metrix´s advanced signal processing software automatically pinpoints any leak(s) present. ZCorr technology is patent-protected (U.S. Patent No. 6,567,006).

DLD is the first true digital leak detector

in the industry. It is light-weight and easy to use. Using dynamic range compression and digital precision, DLD easily identifies leaks that are undetectable with other leak detectors.

MLOG is a network of intelligent, water leak detecting

sensors which monitors the entire water distribution system 365 days a year. MLOG is the first affordable and comprehensive solution to minimizing water losses in a distribution system. Leak detection data is collected automatically by radio from throughout the distribution system (optionally as part of the meter reading process). With many advanced software features, the patented MLOG system can detect and localize leaks and direct pinpointing, repair and remediation efforts (U.S. Patent No. 6,957,157)

The third generation of the DigiCorr -

the original true digital correlator.

DigiCorr III uses state-of-the-art sound processing and high resolution digital radio links to find leaks other correlators miss. DigiCorr technology is patent-protected (U.S. Patent No. 5,974,862).

These light-activated digital sound loggers economically survey

a wide area of a distribution system for leakage. They rule out leakage in most areas, allowing leak pinpointing efforts to be productively concentrated in areas where leaks are probable.
