METHOD AND INSTALLATION FOR DETECTING FLUID LEAKAGE FROM A PIPELINE

摘要

A pipeline leakage detection method and installation including measuring fluid flow rates in the pipeline at spaced points and obtaining summated and differentiated electrical current values corresponding to differences in the measured rates. Increases in current rates corresponding to a pipeline break are instantaneously relayed to means for sounding an alarm and to means for preventing further leakage flow of liquid product in the pipeline.
