Abstract
The air-to-liquid (A/L) ratio in vacuum assist vapor recovery dispensers of fueling systems is controlled by utilizing an in-station diagnostics (ISD) system interfaced with the dispenser or a dispenser diagnostics system. Diagnostics systems monitor the performance of the vapor recovery system according to a number of variables. In one embodiment, a diagnostics system is configured to monitor the A/L ratio of each dispensing event using a flow meter placed in the vapor line and a fluid meter placed in the fuel supply line.
