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
