Summary Water leakage is a common problem that often results in water waste, damages, and hazards to public health. Existing leak detection tools and methods typically rely only on one sensor to detect and pinpoint leaks, therefore the leakage is not identified until the water has risen above the surface. This thesis addresses this shortcoming by developing a fuzzy logic algorithm that is fed with multi-sensor fusion data from flow rate and pressure sensors and accelerometers. Results show that the algorithm can detect leaks and categorize the leak size as small, medium, and large. Future development will focus on testing the algorithm with various parameters such as pipe diameter and materials and using wireless networks to transfer data between sensors and central processing station.
