In the logger lists, any unusual measurement results are highlighted by colour.
The display of measurement data provides detailed information about noise level and frequency, as well as the date and time

Leak detection – seeing and hearing
See leaks – thanks to frequency analysis
Sebalog N-3 loggers measure the noise level (db) and the frequency of a leak simultaneously. High noise levels are
an indication for a leak, but only the combined analysis of noise level and frequency can help identify the approximate distance of the leak in relation to the deployed noise loggers. The user receives visual assistance from a colour scale of blue (low frequency) to yellow (high frequency).
Hear leaks – this is what they sound like
Audio data recorded by the loggers can be played using the Commander-3 evaluating unit or the PC software. This helps the user to analyse the data and differentiate interfering noise from real leak noise.
Real-time measurement – completely
up to date
Sebalog N-3 loggers can transmit noise level, frequency
and audio data in real-time to a reading unit, such as Commander-3. In this way the readings can be confirmed directly on the spot without any additional measuring equipment.
Professional evaluation – the ESA value
ESA stands for “Enhanced Spectrum Analysis” and means that noise level and frequency are combined in one reading. This results in a completely new view of the measured data, which makes the leak probability and position visible in relation to other loggers.
The network mode – all measurement data available anytime!
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.
Efficient work – easy to operate
SebaKMT has pursued the philosophy of “EasyGo” for years, which enables the user to easily operate all the equipment, make all the settings and evaluate all the data.
What was yesterday?
Thanks to the history administration in Commander-3 and
PC software, data already recorded can be retrieved anytime. Have a look in the history for a direct comparison of two loggers or two measurement readings from one logger.
