Multi-point correlation system for leak location

Enigma is a state-of-the-art digital correlation logging system for determining the location of leaks in buried water pipes. Enigma combines noise logging and noise correlation into one operation to provide improved operational efficiency.

Enigma offers the following features

  • Leak detection and location in one operation
  • Optimum performance in difficult leak detection situations
  • Avoids costly night-time working
  • Three sound samples separate genuine usage from leakage
  • Latest 24-bit technology
  • Finds multiple leaks
  • Powerful analysis software

Enigma loggers are deployed at multiple positions, typically on valves or hydrants, during normal working hours. They maybe programmed for either daytime or night-time operation. The 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.

Programming and data readback utilises optical and USB communications to ensure rapid operation.

Two systems available

  • Enigma (8 logger system – as shown above)
  • Enigma-Compact (3 logger system)
