ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual CHAPTER 1 Introduction The ADS® Enigma® is a compact, easy-to-deploy leak detection and location system designed for use with buried water pipes. Using the latest advances in digital acoustic technology, it combines noise logging (leak detection) and leak noise correlation (location) into a single, simple operation. Actual sound is recorded by a network of Enigma loggers, typically deployed on valves or hydrants overnight.

ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Leak analysis with the thumbnail results sorted based on the peaks Confidence Checkbox Selecting this checkbox colors the background of the correlation thumbnails based on the degree of confidence that the correlation peak represents a leak. The software indicates confidence based on the presence of the peak in all epochs, the consistency in the approximate shape of the peaks, and the peaks sharing the same position on all epochs.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Sort and confidence display Instances may occur where sort and confidence processing indicates a lack of consistency in the ordering of thumbnails with red and yellow backgrounds. When this occurs, examine the three epochs of the correlations to identify a potential reason that the colors may be out of order.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Disable Correlations may be disabled and excluded from the analysis. To disable a correlation, right-click on the correlation and then select the Disable option. The software moves disabled correlations to the end of the main display and excludes them from the calculations.

Therefore, when using the hydrophones, ADS does not recommend using Auto Filter. The Analysis Options and Filter Settings dialog allows you to select various filters and options to manage the leak detection process. The filters are band pass filters. You can select up to three.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Filters 1 to 3 This feature allows you to select up to 3 filter bands manually. This can be done either by clicking the filter box and manually entering the filter frequency required or by dragging and dropping on the frequency spectrum display. Restore Default Filters Selecting this button restores the default settings.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Advanced Options on Filters tab Advanced Options This section includes several advanced filtering options. Equalize Auto Filter Selecting this option applies the Spectral Equalizer while the Auto filter is processing data (rather than afterwards). Occasionally, this filter can improve the correlation result. Using this option may increase the operational time. Refine Auto Filter Selecting this employs the refined auto filter.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Center Correlation Suppression Width Center correlation peaks occur due to unwanted noise that is common to both loggers. Designate the number of milliseconds of correlation data to remove from the center of the correlation. Display Coherence Selecting this option adds a third green trace to the frequency display. The coherence shows the similarity between the two logger recordings at each frequency.

ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Auto Velocity at Out of Bracket If, during the analysis, a peak displays close to a logger position, but should display at the end, use the Out-of-Bracket function to compensate for the inaccurate velocity of sound in the pipe. Note: Use this function only when a known out-of-bracket condition exists. To obtain an accurate result using this function, the value entered for the distance between the sensors must be correct.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Once re-correlation is complete, the peak moves to the end of the pipe and the calculation changes the default value to a calculated value.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Leaks (Leak Markers) Selecting this button allows you to mark leaks or points of interest found on the pipe model. Leak markers will display automatically in Network Mode. However, please note that leak markers that are out of bracket will display on the analysis screen, but not in Network Mode.

ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual CHAPTER 7 Principles of Leak Noise Correlation Note: ADS strongly recommends that all users read this section, even those with prior experience in correlation techniques. Leak Noise The loss of water through a leak in a pipe creates a source of noise. This noise, which travels from the leak in both directions (upstream and downstream), is used to determine the location (or source) of the leak.
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual between the arrival of the noise at A and at B. Assume the velocity of sound is V, and the distance between the loggers is D. If the distance from X to B = V * t, then D = (2 * L) + (V * t).
ADS Enigma/Enigma-Compact/Enigma-hyQ User Manual Noise Sources Close to Loggers Loggers located directly over or very close to a leak may not be able to accurately locate the source of the leak noise. When this occurs, move the affected logger further away from the source of noise. Problems with Trunk Mains and Plastic Pipes It may be difficult to obtain satisfactory correlation when examining trunk mains or long lengths of plastic pipe.
