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.

SoundSens is a portable multi-sensor leak detection system designed for fast and accurate pinpointing of hidden leaks in water distribution networks. It uses multiple Bluetooth®-enabled acoustic sensors to capture synchronised recordings at different points on the pipe network and applies correlation analysis to identify the likely leak location. The sensors are configured, time-synchronised and deployed on accessible pipe assets, while setup and data retrieval are handled through the MicroStream App. This removes the need for a laptop or specialist on-site software and makes the system suitable for efficient field surveys in real-world network conditions. SoundSens is suitable for both continuous and diagnostic survey work across complex and interconnected pipe networks. Scheduled recordings can also be carried out during quieter periods, such as at night, helping improve the quality of leak noise detection. SoundSens helps reduce the time required to locate leaks, supports more targeted repair work and improves the efficiency of water network maintenance. Its multi-point correlation capability allows several sensors to be used together, helping operators identify hidden leaks more quickly and with greater confidence.
