Abstract :
This paper presents an educational experiment designed for enabling students to interact with a domain of great interest - leakage detection and monitoring. Students will create LabVIEW/MATLAB programs and will use already existing applications in order to get familiar with signal processing concepts like Cross Correlation, Time Delay Estimation and Signal Whitening. Their activity is supported by a real experimental installation which simulates a water transportation system with liquid loss. In addition to the educational component, a professional leak detection device (the Correlux P200) is used for experimental results validation. Consequently, the students benefit from understanding how such an instrument works.
