The key to digital network monitoring

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 acoustic monitoring of drinking water pipes. It detects and documents characteristic noises caused by leaks in pipes - the so-called leakage noise. The loggers are mounted directly on fittings such as gate valves, hydrants or house connection valves and record the sound activity in the network over defined periods of time.

Functionalities

How does a noise logger work?

A noise logger records the sound waves that propagate through the pipe system. If water escapes at a leak, a continuous leakage noise is generated that is transmitted along the pipe walls over long distances. The logger records these noises and evaluates them.

Modern devices - such as SmartEAR® - use intelligent algorithms to differentiate between ambient noise (e.g. traffic noise, pump noise) and typical leakage signals. This allows actual leaks to be reliably detected and localized - even in complex network structures or 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.

Your advantages at a glance:

  • Early leakage detection.
  • Efficient grid monitoring: Particularly suitable for night-time measurements.
  • Automated evaluation: time savings for your team.
  • Reduction of operating costs: fewer losses, less effort.
  • Updateable and cloud-based.

Areas of application for noise loggers

  • Monitoring of main and feeder lines.
  • Control of problematic network sections.
  • Network analyses in water protection areas.
  • Prevention of burst pipes.
  • Follow-up of leak reports from the public.

Noise logger with cloud connection

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

There they are available to water masters and technical managers - including visual and acoustic evaluation. This makes it easy to analyze and evaluate suspected leakage points - regardless of location, whether in the office or on the road.

Noise logger compared to other leak detection systems

While devices such as 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.
