accurate remote leak location

ADVANCED | MARKET-LEADING | INNOVATIVE

A correlating acoustic leak logger for pinpointing leaks remotely in plastic and metal pipes, in large diameter pipes and over long distances, installed as part of a network of loggers either permanently or as "lift and shift".

Correlation analytics

Leak noise signals are transmitted accurately to the cloud analytics platform, PrimeWeb. 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.

Enigma3HYQ accurate leak detection technology
Enigma3HYQ has an advanced Antenna for accurate leak detection
Antenna below ground

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.

Hydrophone sensor

The highly sensitive hydrophone sensor in the Enigma3hyQ 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 Enigma3hyQs 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.

Data platform

The Enigma3hyQ is supported by the Ovarro data platform, PrimeWeb. 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.
