Abstract
A method and improved apparatus for detecting leaks in pressurized pipeline 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 mean temperature of the liquid and the pressure-induced perturbations of the temperature of the liquid.
