Correlators

Fuji LC-5000 is a high-precision professional multicorrelator designed for water network diagnostics, developed in Japan with a strong focus on measurement accuracy. The device is capable of simultaneously analyzing up to 6 correlation routes, displaying the results on a single screen, which significantly speeds up the leak detection process. 4-sensor correlation allows leak analysis from multiple directions, significantly improving localization accuracy compared to traditional 2-point correlators. The built-in logger function enables data recording even in situations where radio communication between the main unit and sensors is limited. The data can be analyzed on-site or later using recalculation. Additionally, the timer function allows analysis of data collected at different times, which is particularly useful for night-time measurements. The system also supports recalculation of data after changes in pipe parameters, allowing results to be refined without repeating measurements.

Touch Pro is a next-generation digital leak noise correlator, engineered for demanding detection environments — including plastic pipelines and large-diameter mains where traditional equipment struggles. Combining precision engineering with intuitive operation, it enables field teams to pinpoint leaks quickly, accurately, and efficiently.

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.
