The correlating acoustic leak logger is designed for precise remote leak detection in large-diameter, long-distance pipeline networks made up of either plastic and metal pipes. It can be permanently installed for continuous monitoring or used in a flexible 'lift and shift' approach as part of a wider logger network.
Highly sensitive hydrophone sensor
Covers entire network, regardless of pipe material or diameter.
Innovative correlation analytics enables water companies to meet regulatory targets
Long distance between fittings means fewer loggers deployed, so reducing costs
Lighter compact design
The Enigma5hyQ enhances leak detection with a user-replaceable battery that allows for swift on-site changes, minimizing downtime and maintenance expenses. Its new lightweight, compact design facilitates easier deployment in underground chambers while maintaining the durability and an increased IP68 rating compared to previous models. These improvements offer increased convenience and versatility, continuing the high performance of the Ovarro Enigma series for water companies.
Leak noise signals are transmitted accurately to the cloud analytics platform, Atrium. Just 0.1 second fluctuation in the time synchronisation of two sound samples can cause 100m error in the location. To calculate accurately the location of the leak, synchronising acoustic sample signals is critical to pinpointing the position of the leak. Ovarro uses its original patented technique to ensure signals are synchronised and leaks are located with very high accuracy.British patent number 2555053.
The Enigma5hyQ simplifies deployment with Bluetooth connectivity, enabling quick setup through the Enigma5 app and removing the need for a communications module. Its advanced MQTT security enhances encryption, ensuring real-time data protection, improved reliability, and seamless interoperability for modern network environments.
The antenna transmits the acoustic signals from the logger coupled to the pipe below ground. Being underground means no planning permission is needed to install transmitters or repeaters, and vulnerable hardware is protected from damage or theft, which can occur on the street.
The highly sensitive hydrophone sensor in the Enigma5hyQ was developed by the US Navy. This sensor, whether integrated into the body of the logger or separate, is inserted directly into the pipe, and detects leaks which other leak detection techniques miss. A network of Enigma5hyQs can cover the whole network, because they can detect leaks in plastic, as well as metal pipes, and in large diameter pipes. Such is its sensitivity, this logger can detect leaks over long distances, so reducing the number of loggers deployed.
The Enigma5hyQ is supported by the Ovarro data platform, Atrium. This provides a database, analysis and online viewing facility for remote leaks in the network, as well as for flow and pressure. It is accessible on any desktop or laptop and displays live and historical data. Indicating accurate leak positions, together with ‘street view’ visualisation of the leak position, helps leakage teams manage their networks.
