Farmer, E

A system is described for monitoring fluid pipelines or pressure vessels to determine the probability of a break, leak or rupture therein using a procedure in which two or more different sets of pressure or velocity measurements, each of the different sets containing a different number of readings, are compared statistically to detect a trend in the readings that would be indicative of a break, leak or rupture. The system comprises: (a) a fluid characteristic measuring means for monitoring a characteristic of a fluid in the pipeline, and which measuring means provides an output signal that is proportional to the characteristic being monitored; (b) statistical analyzer means receiving the output signal from a measuring means and providing a statistical analysis of the data from a transducer means to determine by a statistical analysis the probability of a break, leak, or rupture in the pipeline, the probability being expressed as an output signal to a display device.
