How to Detect so2 leakage pdf

4.3 Correlator Leak Detection Leak correlators (Fig. 4) identify the acoustic frequency made by water escaping from a pipe. The correlator uses two sensors placed over the pipe length which detect the noise of the water escaping from the leak and calculates the leak's location by comparing the delay in the signal reaching each sensor. There ...
