An automated filling system to conduct a filling operation in which a bulk liquid transport vehicle is filled with a bulk liquid and quality assurance tests are performed by a gas analyzer. A programmable logic controller, employed to control the filling operation, is responsive to pressure within a fill line connected to the vehicle and is programmed to determine that there exists sufficient pressure within the vehicle to conduct an initial quality assurance test and that the fill line is properly connected to the fill line, without breaks in its flow integrity. The programmable logic controller also initiates and controls a pressurization process if there is not sufficient pressure to conduct the initial quality assurance test.
