 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.
Benefits
- Easy to use
- Optimised for plastic pipes
- Long operating time
- Sensor can be connected to the central unit
- Sturdy housing
 All advantages at one glance
- Easy handling with rotary encoder
- Rugged and compact design
- Simultaneous display of the correlation chart and the coherence spectrum (FFT- analysis)
- Quick fi lter 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 fi lter adjustment 0 … 4000 Hz
