Correlux P-2: Digital correlator for leak location on water pipelines

The correlator Correlux P-2 is used for leak location on pipes for portable water. Water, escaping from a leak under pressure creates a noise which travels into both directions of the pipe. This noise is recorded by two sensors (piezo-microphones, hydrophones) attached to the pipe (e. g.: valves, hydrants), amplifi ed and transmitted to the correlator. The Correlux P-2 compares both signals (correlation) and calculates the exact distance to the leak by use of the signal delay, the sensor distance and the sound velocity.

Key benefits:

• Easy handling with rotary encoder
• Rugged and compact design
• Simultaneous display of the correlation chart and the coherence spectrum (FFT- analysis)
• Quick filter optimisation without using menus
• Fast and easy leak identifi cation by using the overview measurement with unknown pipe parameters
• High radio output for broad reach
• Transmitter and correlator with direct headphones plug-in to listen live to the leak noise
• Recharging the complete system in the closed case – direct charging is possible, too
• Up to 6 pipe sections measurable
• Active piezo ceramics accelerometers, best suited for plastic pipes
• Automatic and manual filter adjustment 0 … 4000 Hz
