A turbine flow meter used as a vapor flow meter in a vapor recovery-equipped fuel dispenser. The turbine flow meter measures the vapor recovered by the fuel dispenser during a fueling operation that is returned back to the underground storage tank. The turbine flow meter measurements may be ignored when fuel is no longer flowing through the fuel dispenser since the turbine rotors in the turbine flow meter may continue to rotate even after vapor is no longer being recovered.
