Abstract:
1. A fuel dispensing system for dispensing fuel from a plurality of dispensing nozzles into vehicles, the plurality of dispensing nozzles being associated with a fuel dispenser having a first dispensing nozzle with a first fuel sensor monitoring fuel dispensed by the first dispensing nozzle and a second dispensing nozzle with a second fuel sensor monitoring fuel dispensed by the second dispensing nozzle, the fuel dispensing system including a vapor recovery system, the vapor recovery system comprising: a return flow sensor providing a return flow signal of an amount of vapor returned by the first dispensing nozzle and the second dispensing nozzle; and a controller, wherein the controller monitors the first fuel sensor, the second fuel sensor, and the return flow sensor and determines A/L ratios for each of the first dispensing nozzle and the second dispensing nozzle, wherein if both the first dispensing nozzle and the second dispensing nozzle are active the controller ignores the return flow signal of the return flow sensor.
