A method of detecting a leak in a pressurized pipeline system, in which a measurement is performed to determine the difference in the rate of change of pressure due to a leak between one pressure level and at least one other pressure level, after compensation has been made for thermally induced changes in the pressure.

Methods for detecting leaks in pressurized piping with a pressure measurement system

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.
