The main purpose of this study is to verify experimentally the method proposed by the authors for estimating the position of a detected leak by applying a fluid transient model to a real-time pipeline leak detection system. The method considers the flow rate and pressure profiles changing along a pipeline in a transient manner. Experiments were carried out on a pipeline of 115m length and 3/4 inch diameter using dry air. Pressure and Reynolds number examined are from 0.098 to 0.127MPa and from 3000 to 12000, respectively. The result shows that, in both steady and transient conditions, the proposed method gives a more accurate estimation of a leak position than do conventional methods which do not consider flow rate or pressure profiles along a pipeline. Additionally, the influence of pipe roughness on the estimation is discussed.
