Sewerin releases new products for professional water leak detection The SeCorr ® C 200 and SeCo r rPhon AC 200 wo r k i n conjunction for the perfect water leak detection: easy-to- read measurement value display and au t oma t ed f i l t e r selection H e r m a n n S e w e r i n GmbH has developed two new devices for professional water leak detection: the SeCorr ® C 200 and the SeCorrPhon AC 200. The portable high-performance SeCorr ® C 200 correlator enables leaks in underground pipelines to be pinpointed reliably, quickly and accurately and with a high degree of automation so as to excavate in exactly the right location. The SeCorrPhon AC 200 combines the characteristics of the correlator with acoustic water leak detection: prelocation, pinpointing and correlation in one single system. Bo t h n ew p r o d u c t s a r e based on the tried and tested housing and hardware concept of the AQUAPHON ® A 200 by SEWERIN. Each 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. SeCorr ® C 200: leak detection without the need for close listening The SeCorr ® C 200 correlator measures the noise caused by a leak in a pipeline simultaneously through A glance onto the display of SeCorr ® C 200 two separate fittings. The highly- sensitive UM 200 microphones detect the noise at the hydrant or slide gate, and the RT 200 radio transmitter then sends the signals to the correlator, which calculates the run time difference between the two measuring points, thereby pinpointing the exact location of the leak based on data on the pipe such as the length, material and diameter, that the operator can programme in advance. The calculation of measurement values with the help of correlation eliminates the need for close listening from the user and is practically unaffected by external sound interference.
