Enigma®-3hyQ has been optimized for leak location in large diameter pipes. Designed to operate over longer distances. Enigma 3hyQ is an improvement on the standard Enigma multi-point correlation logger. It uses a high sensitivity hydrophone which directly detects the pressure wave in the water, coupled with narrow band filtering.
Enigma-3hyQ loggers are deployed during normal working hours at multiple insertion points along a main. Enigma-3hyQ gives optimum performance by recording the leak sound at night – when background acoustic noise is lowest and water pressure is usually highest. When retrieved the leak sound is transferred to the host software where it is processed to display leak positions.
Programming and data read back uses optical and USB communications to ensure rapid operation.
