Enigma® – Digital Multi-Point Correlation System for Leak Detection Enigma® is a next-generation digital correlation system designed for highly accurate leak detection in buried water pipelines. The loggers are installed at multiple locations — typically on valves or hydrants — and can be programmed to operate during either day or night. The system combines noise logging and correlation analysis into a single process, significantly improving detection efficiency and reducing the need for costly night-time operations. Each logger records in three sample periods, allowing clear distinction between continuous leak noise and normal water usage. Key Features: Exceptional accuracy even in challenging environments Advanced 24-bit digital correlation with noise filtering Simple setup and fast data retrieval (USB or optical) Long operational life — up to 5 years without battery replacement Automatic velocity detection and unwanted noise suppression Enigma® enables fast, reliable, and precise identification of leak locations between multiple deployed units — helping reduce water loss and maintain efficient network performance without unnecessary excavation work.

PrimeTrace is an advanced gas detection system designed for pinpointing water leaks in all types of pipe materials — including metal, plastic, and composite. It uses hydrogen gas detection, one of the most sensitive and reliable methods available, capable of identifying even the smallest leaks that traditional acoustic methods may miss. The system operates with a safe 5% hydrogen and 95% nitrogen gas mixture, which is non-flammable, non-toxic, and environmentally safe. The tracer gas is injected into the water pipe through a hydrant or service connection, travels with the water flow, and escapes at the leak point. Because hydrogen is the lightest element, it rises through soil and flooring to the surface, where it can be easily detected by the PrimeTrace sensors.

The logger is fully compatible with the PrimeWeb analytics platform, allowing seamless data processing, analysis and long-term performance tracking. Phocus3m can be used for: permanent leak monitoring on distribution mains, semi-permanent installations, or diagnostic “Lift and Shift” surveys, where the logger is periodically relocated between different network zones.

ST20 LISTENING STICK High-performance mechanical acoustic tool for leak detection The ST20 Listening Stick is a robust, high-sensitivity mechanical listening instrument designed for fast and accurate water leak detection on external water distribution networks. It uses pure mechanical amplification through an acoustic resonant chamber, significantly improving leak sound detection on valves, hydrants, service connections, and other pipe fittings. The stick consists of two chromium-plated steel sections that screw together, forming a standard 1.5-meter length. A compact 1-meter version is also available. Leak vibration signals are transmitted through the steel rod to a brass diaphragm inside the resonant cavity, where the noise is mechanically amplified, allowing the operator to clearly distinguish leak noise from ambient system noise—without any electronics. Constructed from chrome-plated mild steel, the ST20 is durable, easy to use, and ideal for both professional leak technicians and users who may find electronic listening devices difficult to interpret. Added benefit A perfect solution for quick valve sound checks — simple, rugged, and practically eternal. An essential instrument for any leak detection technician working on external water mains.
