The SeCorrPhon AC 200 combines the characteristics of a correlator with acoustic water leak detection. This makes it an all-in-one device for leak detection, which brings together the three important functions of prelocation, pinpointing and correlation in one single, functional system. Users can react to any location scenario, even in the most challenging of conditions. Switching between the different functions or processes is simple and fast.
How it works
The SeCorrPhon AC 200 makes structure-borne and ground-borne noises caused by leaks from water pipes audible to the human ear. The frequency spectrum is traced and made visible on the device, and the current acoustic intensity is shown as both a graph and numeric readout. The user can also see the precalculated volume settings and the current frequency analysis of the device on the display at all times.
To then carry out the pinpointing of the leak, the user uses the TS 200 carrying rod and BM 200 (for paved surfaces) or BM 230 (for unpaved surfaces) ground microphone on the section found during the preliminary detection stage. The SeCorrPhon AC 200 transmits the acoustic signals and shows the intensity as a graph on the screen, pinpointing the leak with sufficient accuracy to allow confident excavation.
The acoustic features of the piezo microphone are outstanding — even the faintest of leaks or leaks occurring in noisy environments can be identified and detected, according to the manufacturer. At the touch of a button, the SeCorrPhon AC 200 will apply tailored filters to the current noises and will automatically select the appropriate frequency ranges. Filter limits can also be adjusted to accentuate the leak noise and to permit improved comparability between recordings (e.g. for use in databases or teaching/presentation purposes).
The SeCorrPhon AC 200 is ideal for use for leak detection across all sections, materials, diameters and lengths of pipelines. Numerous additional functions are also available for complex location scenarios.
