Detecção de fugas em tubulações atraves do metodo de resposta em frequencia e reflexões de pulsos de alta frequencia

TL;DRAbstract

In liquid fluid transport systems, there is a concern about avoiding leaks. Thus, this work has as objective to improve the leak detection method in pipes by frequency and time domains response method, being used as mathematical tools the method of Transfer-Matrix / by frequency response and the Method of Characteristics / the Fast Fourier Transform, being demonstrated the advantages and disadvantages of each method. And, as new contribution, propose a leak detection method through the analysis of high frequency pulse, detecting the leaks through determination of time that a pulse produced by the valve takes to go through all pipe and come back, is denominated as a reflected pulse.
