METHOD FOR LOCALIZING A LEAKAGE IN A PIPELINE SYSTEM

摘要

The method comprises measuring the operating pressure at a plurality of measuring positions in a pipeline system and detecting the presence of a leak in any convenient manner. The pressure measurements from each location are stored in such a way that at any given time the pressures measured at each location during a previous time interval of a certain length is in storage. When a leak is detected, the stored pressure measurements are analysed in order to localize the leak. By storing the pressure measurements, preferably locally at the measuring positions, it is possible to have the necessary information in storage for the analyses whenever a leak is detected and the analyses may be performed off-line with ample time for performing the analyses and the pipeline system can be shut down as soon as the leak is detected.
