摘要：
A method for measuring thermally corrected leak rates in a pressurized pipeline system. The pipeline system is pressurized to at least two different pressures, and changes of volume of product required to maintain approximately constant pressure are measurized at each pressure. A temperature-compensated volume rate is computed.
