- Enigma-hyQ is a variant of the standard Enigma multi-point correlation logger that has been further optimised for leak location in large diameter pipes and over longer distances. A high sensitivity hydrophone is used (directly detects the pressure wave in the water) coupled with the application of narrow band filtering.
- Enigma-hyQ loggers are deployed during normal working hours at multiple insertion points along the pipe. Enigma-hyQ gives an optimum performance by recording the leak sound at night – when background acoustic noise is lowest and water pressure is usually highest.
- Enigma loggers record the actual leak sound. When retrieved the leak sound is transferred to the host software where it is processed to display all leak positions between loggers.
- The Enigma has a proven track record of finding leaks that competing products cannot find. It provides the optimum in correlation technologies available.
