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 Eureka5 is a next-generation correlation-based water leak detection system, designed for high-precision leak location even under challenging conditions and on plastic pipes. Rugged, portable, and field-ready, it’s built for daily use by utilities, contractors, and leak detection professionals who need reliable results on-site. Key Features In-case battery charging – Batteries can be charged directly inside the rugged transport case, from either mains power or a vehicle, ensuring the system is always ready to use. Intuitive software and touchscreen control – Easy-to-use interface with auto filter selection based on pipe material for fast and accurate operation.
