Abstract:
A vapor recovery-equipped fuel dispenser that dispenses fuel from a storage tank to a vehicle and recovers vapor from the vehicle during refueling, comprising:a fuel conduit that carries the fuel from the storage tank; a vapor return line that carries the vapor from the vehicle back to the storage tank; a hose and nozzle combination fluidly coupled to said fuel conduit and said vapor return line wherein said hose and nozzle receives the fuel and delivers the fuel to the vehicle, and wherein said hose and nozzle receives the vapor recovered from the vehicle to return to said vapor return line; a fuel flow control valve located inline to said fuel conduit, wherein a control system controls the opening and closing of said fuel flow control valve to control fuel flow through said fuel conduit; a fuel meter located inline to said fuel conduit that measures the amount of fuel received from the storage tank, and communicates a fuel flow signal to said control system; and a turbine vapor flow meter located inline to said vapor return line that measures the amount of recovered vapor, and communicates a vapor flow signal to said control system; said control system adapted to ignore said vapor flow signal when said fuel is no longer being dispensed to the vehicle.
