N3 Noise Loggers
Water escaping a leak under pressure causes the pipe wall to vibrate. These vibrations can be sensed acoustically on valves using the latest noise level logger technology. Sebalog N3 noise level loggers not only detect the noise level of a water leak, but also the frequency. Using both these factors, the leak probability can be determined, as well as the relative leak position in relation to adjacent loggers. User-friendly computer software as well as the established SebaKMT “easyGO” principle help the user to locate leaks efficiently.
- Audible and visual leak detection
- Stores noise level and frequency
- Audio data recorded directly in the logger
- History function and comparison of measured data Real-time measurements
- TNC version with external antenna available
Audio data recorded by the loggers can be played using the Commander-3 evaluating unit. This helps the user to analyse the data and differentiate interfering noise from real leak noise.
Sebalog N-3 loggers can transmit noise level, frequency and audio data in real-time to a Commander-3 reading unit. In this way the readings can be confirmed directly on the spot without any additional measuring equipment.
Permanent pipe network monitoring is becoming an integral part of drinking water supply. In addition to proven technology such as Lift&Shift or patrol, the Sebalog N-3 system is able to transmit measurement data by GSM directly to the control centre using a newly developed network mode.
The combination of remote data transmission and professional user software enables the user to search for the leak exactly in the places where there is a high probability of a leak. This effective pre-location method saves valuable time and money.
