Permanent Network Monitoring
Permanent Network Monitoring technologies allow utilities to identify and pinpoint leaks in their monitored pipe network moments after occurrence and initiate appropriate actions. Permanently installed intelligent sensors provide daily information (noise level histograms, frequency spectrum, correlation data, actual sound recordings) and therefore provide the operator with the best possible solution in terms of acoustic leak detection capabilities.
Acoustic Microphones
Providing superior sensors and greater amplification than most other acoustic leak detectors in the market, the Aquascope product range will help leakage operators find more leaks.
Leak Noise Correlators
Our high-performance leak locating correlators are appreciated by customers for their physical robustness, their elegant design, their long-term reliability and their ease-of-use. Lab tests have also shown that the performance and accuracy of our correlators are among the highest in the industry. Choose between various levels of correlators that can be used in standard situations or more difficult environments (including trunk main leak detection).
Correlating Leak Noise Loggers
GUTERMANN`s Zonescan 820 product range is cutting-edge and outperforms all other loggers available on the market. They are extremely small and robust, have the highest sensitivity, the strongest radio (proprietary radio), smart firmware, and nonetheless an impressively long battery-life. But most importantly, our loggers do not only provide noise-level data and advanced spectrum analysis, but they can also correlate and are therefore able to pinpoint leaks with high accuracy.
Pipe & Valve Locators
Our pipe and valve locators complete the range of acoustic leak detection equipment. Our equipment is designed to be effective and easy to use.
