Product description

Advanced monitoring for real-time leak and intrusion detection in pipelines

Detect leaks and intrusions in pipelines carrying drinking water or other liquids using Distributed Acoustic Sensing (DAS) and fiber optic technology. With advanced 24/7 monitoring, DALI helps utility companies and industrial facilities reduce Non-Revenue Water (NRW) losses, minimize waste, and prevent costly incidents. The system provides real-time alerts with 5-meter accuracy over long distances and is compatible with pipelines of any size or material, including plastic.

Unlock the full potential of fiber

DALI requires only one optical fiber for monitoring while enabling other fibers to connect and remotely control network assets such as valves and sensors. This setup supports robust data communication networks, transforming water pipelines into fiber backbones in partnership with telecom operators. With a capacity of up to 144 fibers, DALI ensures secure connections to network infrastructure and opens opportunities for leasing fiber capacity to telecom providers.

How it works

From monitoring to actionable insights

DALI leverages advanced fiber optic technology with Distributed Acoustic Sensing (DAS) to detect leaks and intrusions in real-time, enabling cost-effective decision-making.

Fiber optic cables

1. Hassle-free installation

A project-specific fiber optic cable is installed within the pipeline, serving as a continuous array of thousands of acoustic sensors that span the entire lenght of the pipeline.

2. Smart pipeline monitoring

The Distributed Acoustic Sensor (DAS) is connected to one end of the fiber and utilizes a laser to send short pulses of light along the fiber. This process generates a unique pattern of reflections. Environmental vibrations create disturbances that alter this reflection pattern within the pipeline. The Distributed Acoustic Sensing (DAS) device analyzes these modified optical signals to detect potential leaks and intrusions.

DALI Dashboard

3. Real-time monitoring and automatic alerts

DALI leverages advanced signal processing and machine learning software to accurately detect events such as leaks and intrusions. Users can monitor pipeline status in real time through an online dashboard, which displays alarms and sends notifications via email, SMS, or SCADA systems.

4. Make smart and informed decisions

The DALI monitoring system offers a long service life and typically costs less than 1% of a complete pipeline replacement. In return, you gain an extended pipeline lifespan, reduced Non-Revenue Water (NRW) losses, and peace of mind regarding your pipeline infrastructure.

FAQ

The DALI team is just a message away.

What kind of sounds can you detect with DALI?

The DAS (Distributed Acoustic Sensor) that is at the heart of DALI detects any sounds or acoustic vibrations on the cable, from sub-Hz to several kHz (kilohertz). It registers any sound, including leaks, pumps, nearby digging activity, or unauthorized intrusions on the pipe. Advanced AI-based signal processing algorithms then filter out any irrelevant signals and raise an alarm in case of a leak or other important anomaly.

How long is the pipeline service interrupted to install the DALI system?

None. The entire DALI system can be installed on a live pipeline, without service interruptions. Thanks to our unique installation system, the fiber optic cable can be inserted, pulled, and extracted from the pipeline while the pipeline remains operational.

What is the maximum distance that can be covered by DALI?

A single DAS can cover up to 70 km of pipeline. If you place the DAS in a central location and use an optical switch, you can even monitor several times that distance. This makes DALI ideally suited for monitoring long, critical trunk mains. The fiber optic cable is installed in shorter reel lengths (facilitating installation and maintenance) and then spliced together into one continuous fiber link.

Can I use the fiber optic cable to communicate with other assets such as valves or sensors?

Yes. The DALI cable contains 12 or even 144 fibers, of which only 1 is needed for the monitoring. The other fibers can be used to create an internal communication network, or even be leased to telecom companies that are developing a fiber backbone.
