Noise logger for leak monitoring in the drinking water network

Whether used individually or as a networked system - noise loggers make the invisible visible. They provide crucial data for the sustainable, economical and safe operation of drinking water networks. With innovative solutions such as SmartEAR® and the POSEYEDON® cloud, SebaKMT® is setting standards in intelligent leak monitoring.

What is a noise logger?

A noise logger is a digital measuring device for the acoustic monitoring of drinking water pipes. It detects and documents characteristic noises caused by leaks in pipelines – the so-called leakage noise. The loggers are mounted directly on fittings such as gate valves, hydrants or service connection valves and record the sound activity in the network over defined periods.

How does a noise logger work?

A noise logger records the sound waves that propagate through the pipeline system. If water escapes from a leak, a continuous leak noise is created, which is transmitted along the pipe walls over greater distances. The logger records and evaluates these noises.

Modern devices – such as SmartEAR® – use intelligent algorithms to differentiate between ambient noises (e.g. traffic noise, pump noise) and typical leak signals. This allows actual leaks to be reliably detected and specifically located – even in complex network structures or in noisy environments.

Why are noise loggers important for the drinking water supply?

Noise loggers enable early detection of such weak points before serious damage such as burst pipes occurs. Thanks to their continuous monitoring, they make a decisive contribution to minimizing water losses, increasing network stability and protecting water resources in the long term.

Areas of application for noise loggers

Noise logger with cloud connection

The latest generation of noise loggers – such as SmartEAR® from SebaKMT® – elevates leak monitoring to a new level. These devices transmit the recorded noise data directly to the POSEYEDON® Cloud via mobile communication standards such as NB-IoT or LTE-M.

There, they are available to water masters and technical managers – including visual and acoustic analysis. This allows leakage suspicion points to be conveniently analyzed and evaluated – regardless of location, whether in the office or on the move.

Noise logger compared to other leak detection systems

While devices such as leak noise correlators or ground microphones are used specifically for pinpoint leak detection, noise loggers are used for comprehensive monitoring of the pipe network.

They detect conspicuous noise patterns and automatically sound the alarm if there is potential damage. This creates an effective early warning system that enables targeted and efficient tracking with other detection methods - before major damage occurs.

Method	Advantages	Time of use
Noise Logger	Area control, long-term monitoring	Early phase, permanent
Leak Noise Correlator	Precise localization	After notification / logger alarm
Ground Microphone	Pinpointing	Final step towards repair
