ABSTRACT:
The present invention provides a fuel dispenser system capable of receiving a signal from a vehicle transponder. Upon receiving the transponder's signal, the dispenser determines the proximity of the vehicle relative to the dispenser, and preferably, a particular fueling position associated with that dispenser. Proximity is determined by measuring one or more characteristics of the signal received at an antenna associated with the dispenser. Generally, the strength or magnitude of the signal received at the antenna is the characteristic used to determine vehicle proximity. Multiple directionally sensitive antennas are used to correlate a vehicle at a unique fueling position. The controller is configured to receive a signal from the transponder indicative of the presence of an ORVR system on the vehicle. Depending on the sophistication of the communication link between the transponder and dispenser, the dispenser will control its vapor recovery system accordingly. If an ORVR equipped vehicle is detected, the dispenser may deactivate the dispenser's vapor recovery system or modify the vapor recovery system performance to maximize vapor recovery or retrieve a sufficient amount of air to reduce breathing of the underground storage tank.
