IMPROVED METHODS FOR MEASURING THE FLOW RATE DUE TO A LEAK IN A PRESSURIZED PIPE SYSTEM

摘要

A method and improved apparatus for detecting leaks in pressurized pipeli ne systems, which compensate for the thermally induced volume changes of the liquid in the line during a test that are produced by both the nonlinear changes in the me an temperature of the liquid and the pressure-induced perturbations of the temperature of t he liquid.
