Abstract
The present invention relates to a fuel dispensing apparatus and method for blending at least one blended fuel using a single meter both the blended fuel and the blend components. The invention includes an apparatus for dispensing a blended fuel that includes first and second valves in fluid communication with a low octane blend component and a high octane blend component respectively. A meter is in fluid communication with the first and second valves for generating a signal indicative of the volume of the blended fuel dispensed from the apparatus. The invention further includes a real time octane sensor in fluid communication with the blended fuel for generating an output signal indicative of the octane level of the blended fuel. A blend controller receives the octane sensor output signal and generates output control signals to the first and second control valves to maintain the blended product octane level at a predetermined level or within a predetermined range.
