Abstract: The purpose of this study was to illustrate the relationship between methods that utilize the damping of fluid transients and approaches based on frequency response diagrams and to discuss the two methods for both leak and burst detection. Although both methods are based on the Fourier transform of the signal, they have different signal processing approaches. This study revealed the mathematical relationship between the two methods for both leak and burst problems. The mathematical relationship between the two methods was verified numerically and experimentally. In addition, the two methods were compared from the perspectives of input signal bandwidth, problem type, low sampling rate capability, robustness, and real-time data monitoring capability. The applicability of the two methods with regard to these aspects is discussed herein.
