This Isn't Just Leak Detection.
It's Continuous Infrastructure Insight.

Kamstrup Acoustic Leak Detection (ALD) isn't a feature. It's a fundamentally different way to run a water system - one where every meter is equipped with ALD turning a routine water installation into a system-wide leak detection network.

Kamstrup ALD is Different

Kamstrup's Acoustic Leak Detection redefines the way utilities tackle water loss. Every flowIQ® meter up to 2” is equipped with built-in acoustic sensors, working 24/7 to detect leak noise. Advanced machine learning then analyzes the sound patterns to distinguish normal flow noises from the tell-tale signs of hidden leaks, no matter where they occur.  All this in addition to the downstream ‘constant- consumption’ leak detection features you expect in a smart meter. 

ALD is integrated into every flowIQ® meter (2" and below) using the same ultrasonic sensor that measures flow, with no additional hardware, no separate installation, and without compromising the core promise of 20-year accuracy and reliability.

A single meter installation delivers over 7,300 automated leak surveys across its 20-year life and regardless of pipe material. It's the only way to turn your meter program into a system-wide leak detection network. 

Unlike standalone acoustic loggers that require replacement every 3-5 years, ALD is built to last the full meter life, with no recurring hardware costs or maintenance cycles.

Kamstrup ALD gives your utility something it's never had before: complete, continuous confidence in what's happening across your entire distribution system. Tapping into your existing infrastructure, ALD provides 10x the sensor density per mile compared to traditional acoustic loggers, eliminating coverage gaps and giving crews a starting point.

“The way the [ALD] software works, you can watch it and prioritize it. Because it's also daily information, constant daily information, the constant flow of data is important to compare the window of resolution that makes sense for us as operators. I need to know on a day-to-day basis what's going on in the system. Twice a year doesn't cut it.”

If You're Meter Doesn't Detect Leaks, It's Obsolete.

The flowIQ® 2200 & 3200 Meters

The flowIQ® 2200 and flowIQ® 3200 ultrasonic water meters (2" and below) are the foundation of Kamstrup’s Acoustic Leak Detection (ALD) solution. Built with integrated acoustic sensors, these meters do more than measure consumption—they continuously listen for leak activity across the distribution system. By leveraging existing ultrasonic measurement technology, flowIQ meters deliver persistent infrastructure insight without additional hardware, batteries, or complexity. The result is a permanent, system-wide leak detection network that helps utilities reduce non-revenue water, prioritize repairs, and build confidence in what their distribution system is telling them.

Software That Locates Leaks

Leak Detector

Leak Detector is a cloud-based platform with integrated GIS mapping that displays leak locations of your meters equipped with Acoustic Leak Detection technology. Leak Detector enables you to locate leaks in service connections and distribution mains based on acoustic noise levels registered by flowIQ 2200 water meters. With the system's advanced algorithm and map-based overview, you can easily identify installations where elevated noise levels indicate possible leaks or bursts.

Service Line Leak Detected in PVC

ONEIDA, TN

A single flowIQ® 2200 meter detected a 4 GPM leak in a PVC service line that had been running for 4.5 months. Located 50 feet from the meter, this non-surfacing leak was losing 111,600 gallons daily at a monthly cost of just under $2,000. With ALD's continuous monitoring, Oneida identified and repaired the leak before it escalated. 

Daily Leak Detection Across 23,000 Meters

BEAVERTON, OR

Beaverton deployed Kamstrup's compact ultrasonic meters with embedded ALD across 23,000 residential connections. With built-in daily acoustic leak detection, the utility shifted from outsourcing to survey 20% of its system annually to continuous, network-wide monitoring, enabling early leak detection and prioritizing repairs with actionable data. 

Faster Leak Detection in Aging Infrastructure

ROW RIVER VALLEY, OR

Facing 100-year-old mains and rising costs, Medford upgraded to Kamstrup ultrasonic smart meters with built-in Acoustic Leak Detection. With technology that detects leaks before and after the meter, Medford is enjoying faster response times and more accurate billing, benefiting this residential community north of Boston.
