LD-7

Compact, easy-to-use Water Leak Detector that fits in the palm of your hand.

Enigma® pinpoints leaks others miss—smart, powerful, and built to listen where it matters most.

Enigma® is an advanced digital correlation logger designed to accurately locate leaks in buried water pipes. By combining noise logging and noise correlation in a single operation, it streamlines the leak detection process and boosts operational efficiency. Ideal for both temporary and semi-permanent deployments, this “Lift and Shift” solution is a versatile tool for water network surveys. Enigma® features powerful 24-bit data processing and analysis, giving it a proven edge in detecting difficult leaks that other systems often miss. Its ability to take and analyze three distinct sound samples allows it to differentiate between regular consumer usage and non-revenue water loss, delivering highly reliable leak detection results.

Trouble free deployment

Enigma correlating leak noise loggers are deployed at multiple positions, typically on valves or hydrants, during normal working hours. They may be programmed for either daytime or night-time operation.

MULTI-POINT NETWORK CORRELATION

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.

OPTIMUM LEAK SENSING

Overnight use provides ideal conditions for leak detection. This is because background acoustic noise from traffic, water usage and other sources, is lowest and, at the same time, water system pressure can be higher which greatly aids leak sound propagation.
