Correlation features
Save results – enables download of data to Enigma software for further analysis
Zoom in/out - magnifies correlation
display
Noise suppress function – suppresses non-leak
correlation allowing leak noise correlation to be
displayed
Velocity correction – overcomes largest error for accurate leak position
Correlation at leak position
Velocity correction mode ‘greys-out’ leak correlation
Then open hydrant and second
correlation peak formed
Distance to hydrant entered
Velocity value confirmed
Measured velocity value used on initial correlation to give
accurate leak position

Reporting + transfer to Enigma®
Eureka3 correlation report
Digital leak noise sound files may be transferred to Enigma
software for further analysis
Enigma® - advanced features
e.g. narrow band filtering
· Automatic ‘filter sweeps’ produce correlations in multiple narrow bands
· Can produce out-of-bracket correlations at low frequencies to determine
velocity
Enigma® mapping software
Eureka3 has GPS facility to store sensor positions
and display leak position on Google Maps
Street-working friendly
Transmitters have integral sensor which connects directly
to pipe such that chamber cover can often close - resulting
in less disruption to traffic
Alternatively use conventional accelerometer or
hydrophone sensors
In-case battery charging
Transmitters and PrimeTouch batteries charged whilst in-
case
Charge from mains electrical supply
Charge from vehicle – whilst driving between sites!
Correlator processor (PrimeTouchTM)
Radio transmitters (pair) with integral accelerometers
Headphones
Transport case (with in-case battery charger)
Mains power supply
Vehicle charge cable
System components
External accelerometer sensors
Hydrophone sensors (typical use on plastic and large diameter pipes)
Sensor extension cable
Accelerometer grip attachment
Magnetic vehicle mount aerials
(for increased radio range)
Optional components
Fast, simple operation - reduced operator training
Velocity correction function - reduces incidence of dry holes
Powerful post-processing via Enigma® software
- for very difficult leaks
- GPS location on Google Maps
Ideal tool for non-specialist and experienced users
Low-cost-of-ownership
- enables use in larger numbers
- cost effective for smaller companies
Innovative correlation technology
for reducing leakage
