With the increase usage of pipeline in industrial process, especially within the gas transmission and distribution systems, it has become very crucial to develop the reliable method for predicting gas release and dispersion in the pipeline due to many reasons such a safety, security and economic reasons, ecological reasons and etc. The predicting should have fast and accurate detection of the leaks. The primary objective of this project is to design a leak detection system in order to test the method and gather experimental data with using method of pressure analysis to detect, as early as possible, the exact location and magnitude of such faults with minimal instrumentation and should have fast and accurate detection of the leaks. The system will combine the use of instrumentation that normally available in the pipeline such as Differential Pressure (DP) Transmitter and orifice. The DP transmitter will indicate the pressure different between inlet and outlet flow which is before and after the leak location. The fluid used is the instrumentation air and the leaks are controlled with variable operating condition. This project will combine all the skill from Instrumentation, Control System and Fluid Mechanics.
