Water leak detection by correlation: professional – flexible – intelligent

Reliably and accurately pinpoint leaks

Professional: The SeCorr® C 200 is a state-of-the-art, portable high-performance correlator, which enables leaks in underground pipelines to be located reliably, quickly and accurately to allow excavation to begin. Its user interface is clearly and logically laid out. There are many extra functions available for complex location scenarios. 

Flexible: The SeCorr® C 200 is recommended for all users undertaking professional leak detection because it can handle any everyday location scenario. It can easily measure different pipe sections, pipe materials, diameters and pipe lengths. 

Intelligent: The sophisticated firmware of the SeCorr® C 200 means that the measurement sequence is almost fully automatic. Once the pipeline data has been entered and the measurement started, all other steps are performed without the intervention of the operator. The measured noises are constantly analyzed in the background and the optimal filter settings selected. 

Now with enhanced functions

Suppression of interfering peaks

The feature of peak suppression helps with optimization in situations where one area of the correlation function is selected and then suppressed. The graph is then normalized in accordance with the next smallest peak, making it much easier to identify. If more than one leak is detected within the correlation line, peak suppression can be used to separate the visible peaks from each other.

Measuring sound velocity

When measuring sound velocity, a second source of noise at a known location is created in addition to the real leak. Two measurements are then taken (one with the second source of noise and one without), and they are used to calculate the sound velocity on the measuring section. The measurements displayed on the receiver focus clearly on the second measurement, paying special attention to the position of the additional sound source. The result is rapid measurement of the sound velocity in just a few steps.

Documentation with WaterCom software

Measurements saved in an A 200, C 200 or AC 200​​​​​​​ receiver can be transferred quickly and easily to a computer via USB. Just connect the receiver to the computer via cable and the measuring data will be transferred automatically. It is possible to set up different user and customer data sets in the software. The position of the location for each measurement is shown on an online map (e.g. Google Maps). The locations on the map can be edited, meaning the exact position of the radio transmitter or damage detected by the ground microphone can be pinpointed exactly. It is also possible to add notes to any measurement or point of damage. The software can generate PDFs to produce paper documentation of any measurements. Noises which have been recorded can be played back using the player integrated into WaterCom. If the software is used regularly to save measurements, it will start to build up a useful noise database. This can then be used, for example, to train new starters in leak detection in what to listen out for.

    Leak Noise Correlator

    Most leak correlators use microphone type sensors to pick up leak sound traveling down the wall of the pipe or tubing. Sound does not travel the same speed or distance on different materials. Sound on Plastic pipe travels only around 200' limiting the usefulness of most leak correlators in plastic pipe systems. The HYDROPHONES  are designed to listen for the leak sound in the water column rather than the pipe wall. Sound travels many times faster in water than on metal or plastic, so hydrophones can increase the performance on plastic pipe greatly. On the C200 and AC200 correlators, the correlation distance can be extended up to 1000' or more plastic pipe with using hydrophones. Hydrophones are connected to two hydrant hose nozzles to correlate for leaks between them. The hydrants do need to be flushed and pressurized with water to correlate. 

    Hydrophone Kit for SeCorr C 200 and SeCorrPhon AC 200:

    • 2 Hydrophones
    • 2 Fire Hydrant Hose Nozzle Adapters (National Standard Thread)
      (you may need thread adapters for custom thread specs)
    • 2 Cables to attach to correlator sensors
    • 2 Flushing hoses
    • Storage box custom cut foam insert

    Large Carry Case Option:

    A larger carry case with in-case charging is available as an upgrade. The larger case will accommodate A200 or AC200 carry rod and microphones if you upgrade  your device in the future to one of those devices.
