Abstract
A method of determining the presence and temperature compensated volumetric flow rate of leaks in fluid pressurized pipelines. The pipeline is maintained at a first pressure and the fluid volume change per unit time is calculated. The pressure is then maintained at a second different pressure and a second fluid volume change per unit time is calculated. The system is then maintained at the first pressure while a third fluid volume change per unit time is calculated. The first and third rates are combined with the second rate to obtain a temperature compensated leak volumetric flow rate.
