SeCorrPhon AC 200
— Correlator, Ground Microphone & Valve listening microphone combined
Three tools in one instrument - Maximum productivity for water leak location
The AC200 offers high-quality piezo electronic microphones with optimised frequency response.
An integrated audio recorder allows the user to record & listen to leak noises on site - Compare sounds from one position to the next
Intelligent frequency filters allow the user to hear & concentrate on likely leak noises & not interfering sounds
SeCorrPhon AC 200 Correlator - Versatility and convenience
- Reliably locate leaks using high-quality piezo microphones with specially optimised frequency responses
- Suitable for all pipe materials, diameters and pipe lengths
- Automated measurement process thanks to intelligent firmware
- Fast and precise leak detection thanks to optimised filter settings
- GNSS module (Global Navigation Satellite System) for precise position documentation
- Suppression of interfering correlation peaks
- Integrated sound velocity measurement
- Clear display of the leak position in metres from each microphone
- Compare leakage sounds on site with integrated audio player
- Fast and reliable user guidance

Locate water leaks with the Sewerin AC200 Correlator which combines Valve & Ground microphones
The SeCorrPhon AC 200 offers the best of all acoustic water leak location technologies combined in one instrument
Confident excavation of water leaks
The SeCorrPhon AC 200 determines the leak's position by simultaneously "listening" at two points on a pipe - If it can "hear" leak sounds at both points & can identify it is the "same" sound it will indicate the leak's position. Use the Ground microphone to confirm
One device - 3 functions
Correlator, Valve listening mic & Ground microphone all combined in one system- Cost effective water leak location
Precise leak positioning
With the integrated GNSS module (Geo location), you can record the leak's position & report it to the repair team

What is correlation? Precise water leak location with Digital Signal Processing
A water leak in a pipe under pressure creates noise that travels along the pipe, its contents, and through the surrounding ground.
When two highly sensitive microphones are attached to a water pipe with a leak between them the sound from the water leak takes longer to travel to the microphone furthest from the water leak; this is called the “time delay” or ∆t.
Utilising this and other known information (water pipe diameter, material and length), the exact water leak position can be automatically calculated by the water leak correlator SeCorrPhon® AC200
Two highly sensitive microphones are attached by magnet, or valve adaptors, to suitable listening positions such as hydrants, valves, the water pipe walls or even directly into the water column using hydrophone sensors. The water leak must be between the two microphones. As long as the water leak noise can be “heard” and recognised by both microphones (correlated) the SeCorrPhon AC200 can process and analyse the resulting information.
The water leak sounds picked up by the microphones are transmitted via two powerful radio transmitters to the lightweight central processing unit, SeCorrPhon AC200 Digital Signal Processor, where the noise information is quickly analysed & the resulting water leak position is displayed both graphically and numerically, as metres to the leak from each sensor.
