Product Features:

The Enigma is a multipoint “Lift and Shift” system of correlating leak noise loggers that are designed to be used as a temporary or semi-permanent water network survey tool. 

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 nighttime 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.

Separating Genuine Water Usage

Each logger records during three sample periods, typically spaced one hour apart. A characteristic of leak noise is that it is always constant and so if the correlation peak is not present during all three samples then it is due to water use and not leakage.

Highlights:

• Logger programming/readback via PC or one button press in the Communications Case
• Loggers powered for 5 years
• Advanced filtering and coherence functions
• Unwanted noise suppression
• Auto-velocity determination
• Pipe schematic with correlation ‘thumbnails’ display
