SeCorr®Phon06 Correlator & Leak listener
A Leak Noise Correlator (LNC) with the latest DSP-techniques for the calculated detection of water leakage, incorporating all the functionality of the Aquaphon A100 Leak Listener!
Key Benefits
Correlator
- Digital Signal Processor (DSP) – Fast accurate calculations allowing quicker leak location
- Direct microphone and headphone sockets – Allows SeCorrPhon® 06 to be used as a basic electro-acoustic leak detector
- High resolution pixel display – High definition of display
- All system components contained in one robust case – All parts can be recharged whilst remaining in the case
- Lightweight ergonomic design – Comfortable to use over a full working day
- Application specific menu structure – Intuitive operator sequences
- Fast Fourier Transformation (FFT) correlation – precise location even with the most challenging leaks
- Radio transmission of over 6667 ft (2,000 m) – Correlation possible over long distances
- Wide selection of components available – Select optimal configuration for the prevailing conditions
- Two levels of software, standard and professional – Chose the version most suited to your requirements.
- Input via jog dial and / or water resistant film pad – Users can select best or both methods according to their personal preference e.g. with gloves on or off
- “Coherence analysis” – Allows automatic or direct settings of frequency filters for optimal performance and easier location of the most difficult leaks noises
Leak Listener
-
Automatic microphone recognition - appropriate frequency settings automatically selected
-
Digital signal processor - for significant reduction of hissing
-
Hearing-protection function - operator’s hearing no longer in danger
-
Filter-optimization function - makes even difficult to distinguish sounds easier to hear
-
Delayed-action display function - displays the lowest level of noise. More useful than the loudest!

Transmitter
As soon as the microphones receive the noise from a leak the signal is automatically amplified to the optimum level and transmitted digitally along with the amplification details to the SeCorrPhon® 06.
Both pieces of information are analyzed and processed by the SeCorrPhon® 06. Utilizing 500mW transmitters signal transmission is clear and strong. Correlation of up to 4km is possible; local conditions may affect the range. Even if the radio transmitter is located within buildings or behind cars or trees correlation can be carried out successfully.
Since correlation requires two microphones, these can either be connected to both radio transmitters or if using only one radio channel, directly to the SeCorrPhon® 06.

Sensors

Highly sensitive Piezo accelerometers record noises in the frequency ranges of approx. 1 to 10,000 Hz. A range of adapters enables connection to a wide variety of measuring points.
Hydrophones do not pick up the sound from the pipe material, but directly out of the water column. This offers a considerable improvement of the location range, especially with correlations on plastic pipes. Locating leaks over several hundred meters is possible.
The Ground microphone BO-4 is especially suitable for paved surfaces. The outside housing of the microphone is acoustically insulated from the internal microphone. The microphone body is mounted in a flexible rubber membrane which can move freely within the housing and it is therefore unaffected by rugged surfaces.
Software
- Software "Professional" for all location demands
- Software "Standard" for the less experienced operators
- Includes fully functional Aquaphon leak listening software
Leak Listening
Using the ground microphone at regular intervals enables the leak to be located with sufficient accuracy for confident excavation. The SeCorrPhon AC 06 displays a precise optical comparison of the noise intensities.Is the noise getting louder or quieter, what is the trend? The noise gets louder as you get closer to the leak and the measured value increases. The optical display is particularly helpful for beginners or those who do not use the system regularly.
