Abstract
A system for monitoring and testing the operation of a vapor recovery system within a fuel dispensing device. The system utilizes strategically placed sensors within the fuel dispensing device to gather data pertaining to each pump and hose combination for that fuel dispensing device. The gathered data is forwarded to an internal digital controller processing device where calculations are performed and results are compared to baseline results stored in memory within the digital controller. Anomalous results are displayed and/or printed. The system operates in both automatic and manual diagnostic modes. The automatic diagnostic mode runs continuously without interfering with the normal operation of the fuel dispensing device.
