Specification: The correlator is used for leak location on pipes for potable water. Water escaping a leak under pressure, creates a noise which travels into both directions of the pipe. This noise is recorded by two sensors attached to the pipe (e.g. valves, hydrants), amplified and transmitted to the correlator. The correlator compares both signals (correlation) and calculates the exact distance to the leak from the signal delay, the sensor distance and the sound velocity.
Features:
Simultaneous display of the correlation trace and the coherence spectrum (FFT analysis).
Automatic and manual filter adjustment.
Automatic correlation for locating leaks on dead ends.
Possibility of measurements on mixed pipe materials with up to 6 pipe sections.
Velocity mesurement for unknown pipe materials.
Optimised display of the correlation trace to safely analyse leaks. Continuous measurement and averaging.
Active piezo ceramic accelerometers, best suited for plastic pipes.
Internal trace memory and PC software for hardcopy and archiving.
Software updates via RS 232 interface.
