Abstract
The principle of operation of a system based on correlation of noise arising at locations of the loss of tightness of a pipeline is described. Acoustic noise received by transducers mounted at the end-points of the controlled section of the pipeline are amplified, filtered by band-pass filters, and coded. The digital data is transmitted to a PC and the measurement results are displayed on a screen in the form of the correlation curves with coordinates of the leakage location of the gas in the pipeline.
