“…In these experiments, different sizes of valves were tested in order to achieve the relationship between the leakage rate and the valve size. The leakage was generated by three ways: the artificial destruction of the valves [26], incomplete closure [27], or simulated leakage source [28].…”

“…Noipitak et al presented a relative calibration method for an internal valve leakage rate measurement system based on the microcontroller and AE methods. It reduced the recalibration time and the cost, which laid a foundation for the application of AE technique in valves [28]. Prateepasen et al developed a smart portable noninvasive instrument for detection of internal air leakage of a valve using AE signals.…”

The applications of acoustic emission (AE) technique in detection of valves are presented in this review, and the theoretical models and experimental results of nondestructive detection of valves using AE are provided. The generation of AE signals and the basic composition of AE detection system are briefly explained. The applications of AE technique in valves are focused on condition monitoring, failure, cavitation detection, and the development of portable measuring devices. All results prove that the AE technique works well in the detection of valves.

“…Moreover, an air-jet (an artificial AE continuous source) was applied to calibrate AE sensor mounting and to transfer the correlated information between the AE sensors. Details of this study, described in term of transfer function between these cases and the precision of the instrument, are given in [17].…”
