Noise loggers

Next-Generation Correlating Logger System for Large-Scale Leak Detection EnigmaREACH is Ovarro’s latest-generation correlating acoustic logger system designed for large-scale water network leak detection. It combines mass logger deployment with advanced cloud analytics to automatically identify leak locations — without the need for manual data processing. The system uploads data to the Atrium analytics platform, where correlations are performed automatically and Points of Interest (PoIs) are generated. These can be assigned directly to field technicians via the intuitive mobile app, significantly reducing analyst workload and accelerating DMA investigations. A single 64-logger EnigmaREACH kit can monitor up to 14 km of pipeline (depending on logger spacing), delivering more than double the coverage of traditional lift-and-shift approaches with fewer loggers. EnigmaREACH is built for professional leakage teams who require speed, precision and scalability.

PCorr+ is a compact and advanced leak detection device that combines noise logging and correlation in one integrated system.

PermaNET SU – Smart Correlating Noise Logger for Continuous Network Monitoring

The Phocus3 is a high-sensitivity acoustic noise logger designed for detecting and localising water leaks in potable water distribution networks. It offers reliable long-term monitoring, secure data storage and convenient data collection via IR or radio communication.

Enigma5M Correlating Leak Logger with GSM Data Transmission (SIM, data transmission and software included for 3 years – Baltic market only) The Enigma5M is a next-generation acoustic correlating leak logger that combines high accuracy, ease of use and advanced data analytics. It is designed for water utilities to efficiently and rapidly detect leaks, even in challenging environments. The device features a user-replaceable battery, enabling quick on-site replacement without downtime, significantly reducing maintenance costs. Its compact and lightweight design ensures easy installation in underground chambers while maintaining the robust quality of the Enigma series. Enigma5M uses a highly sensitive acoustic sensor capable of detecting even very small leaks over long distances, reducing the number of loggers required per kilometre of network. Integrated data transmission and analysis via the Atrium platform ensures precise leak localisation using patented signal synchronisation technology. With Bluetooth configuration, a mobile app (iOS / Android), and secure data transmission (MQTT), Enigma5M enables fast deployment and reliable operation in real-world conditions.

PermaNET+ is an award-winning leak detection system that combines an advanced acoustic sensor with reliable telemetry technology to create a permanent, connected network for continuous leakage monitoring. As the next evolution in noise logging and leak detection, PermaNET+ offers a practical and scalable solution designed for utilities that need to monitor large and complex water networks efficiently. Fully compatible with Google Maps, the system provides real-time visualisation of logger locations, helping leakage teams to quickly identify and prioritise leak events across their network.
