Fluid Conservation Systems has released an Automated Filter Intelligence System (AFIS) for its TriCorr Touch correlator. The new feature further increases the correlator’s ability to accurately pinpoint leaks. TriCorr Touch uses information gathered from acoustic leak noise sensors placed at intervals along a pipeline to identify and locate leaks in a water distribution system. Due to the number of unknown variables that can change the frequency of leak noise, accurate results depend upon using the correct noise filter setting. While most correlators include default filter settings for different pipe materials and sizes, TriCorr Touch’s AFIS automatically runs 55 different filter combinations on the correlation data. This allows TriCorr to check the quality of the results and optimize filter settings as required, until the clearest and most accurate result is presented.
