SeCorr® AC200 Correlator & Leak Listener

The SeCorrPhon AC200 system from Sewerin is a multifunctional ultimate leak tool combining in a single tough carry case an Aquaphon A200 acoustical water leak detector & SeCorr C200 water leak correlator. The SeCorrPhon AC200 platform offers a large 5.7' high-resolution VGA display, a touchscreen that can be reliably operated with gloves and an operating system that is clearly laid out and easy to operate.

Key Benefits

System components


  • Display 320 x 240 pixels with background LED illumination

  • PC connection for information download

  • Socket for direct connection of a variety of microphones

  • BNC connector for antenna input with 90 deg rod aerial (rotary)

  • 1 or 2 radio channels

  • Built in NiMH rechargeable batteries and 12V socket for direct power or charging from vehicle

  • Operating by 12 V= from a vehicle is possible

  • Operating/storage temperature: -10° … +40 °C / -20° … +60 °C

  • Weight: approx. 1.3 kg

  • Dimensions (W x H x D): approx. 12.5 x 18 x 6.5 cm

  • Operating time: approx. 8 hours



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® AC200.

Both pieces of information are analyzed and processed by the SeCorrPhon® AC200. 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® AC200.

  • Automatic microphone recognition when attached

  • Automatically on when microphone connected

  • Selectable low-pass filter to increase performance on non-metallic pipes

  • Automatic signal control

  • 500 mW output power level with optimal selectivity

  • Operating/storage temperature: -10° … +40 °C / -20° … +60 °C

  • Weight: approx. 1.3 kg

  • Dimensions (W x H x D): approx. 12.5 x 19 x 7.3 cm

  • Operating time: approx. 10 hours


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 BM-200 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 is Easy to Use w/ Simple Screens


Leak Listening

Using the ground microphone at regular intervals enables the leak to be located with sufficient accuracy for confident excavation. The SeCorrPhon AC200 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.
