Acoustic Leak Detection

Today, leak detection, especially in service connections, is often a time-consuming, inefficient and expensive task. With limited knowledge of what goes on in your distribution network, it is usually based on a combination of trial and error, theoretic models or simply gut feelings. 

With water resources getting more and more scarce, we need reliable and innovative solutions that protect your water and resources. Therefore, we don’t just talk about fighting water loss, we think forward to raise the bar for it. The result is the next level solution for smart metering with acoustic leak detection. Get full transparency of your distribution network, the tools you need for efficient leak detection and a proactive approach to fighting water loss. Identify and verify potential leaks before they develop into bursts, and target your resources where they deliver the most value.

The state-of-the-art flowIQ® 2200 ultrasonic water meter introduces integrated acoustic leak detection that enables you to monitor your service connections for possible leaks. With its best-in-class low start flow of 2 l/hour, it measures even the smallest consumption. The meter is highly stable throughout the entire dynamic range with a very low error margin – and as a static meter without moving parts, it maintains the same high accuracy throughout its lifetime of up to 16 years.

Like a fine-meshed network of noise-loggers, all your meters monitor the noise in the distribution lines and service connections to detect possible leaks – 24/7. In other words, you don’t require separate noise loggers around your supply area as your meter work for you. Learn more about the new solution in our video.

In one residential area from the 70´s with high leakage levels, VandCenter Syd suspected leaks in the service connections, but lacked the tools to tackle the problems effectively. After installing Kamstrup’s new flowIQ® 2200 water meters with integrated acoustic leak detection and using the Leak Detector analytics app, they quickly were able to pinpoint high-risk areas and identified six leaks that otherwise would have never been found.

Söderhamn Nära went from a costly and time-consuming hit-and-miss approach to leak detection to a targeted effort with their new acoustic leak detection solution. While part of a 4-year plan towards hourly values and analytics, the new solution literally delivered from day one and learnings increase steadily.

A development project in close collaboration with Skanderborg Utility has provided new knowledge on the sound and noise generated by leaks in the distribution network. This has formed the basis for new and innovative leak detection in Kamstrup’s newest water meter, which Skanderborg Utility expects will create considerable value.
