Title: An Acoustic Method of Leak Flow Measurement
Abstract: Acoustic emission techniques have been used for a number of years to locate leaks, but there is still a lack of knowledge of measuring leakage flow rate by using acoustic emission techniques in factory environments. In order to develop a new method with acoustic emission techniques for measuring the leakage flow rate, an experimental program of leakage flow rate testing has been carried out for artificial circular leak holes in piping under different pressure condition and pipe materials. Results show no differences in A-weight sound pressure level (SPL) for the same diameter leak holes on six pipes tested. The expressions hold for a gauge pressure from 200kPa to 900kPa, with a range of 2 dB(A). The standard curves plotted from circular holes can be used to determine other unpredicted leaks, and the differences between experimental results and readings from reference curves are within 5%.
