The present invention relates to an apparatus for dispensing a blended fuel including first and second real time octane sensors in fluid communication with sources of low and high octane blend components. The sensors generate an output signal indicative of the octane level of each component. The apparatus also includes first and second flow control valves in fluid communication with the first and second octane sensors respectively for independently controlling the flow rates of the low level and high level blend components. The invention further includes first and second meters in fluid communication with first and second flow control valves respectively for generating a signal indicative of the flow rates of the first and second blend components. The meters discharge to a blend manifold for mixing the blending components. A controller is provided for receiving outputs from the first and second octane sensors, first and second meters, the blended product octane sensor and generating output control signals to first and second flow control valves so as to maintain the blended fuel octane level at a predetermined level or within a predetermined range. In an alternative embodiment, only a blended product octane sensor is provided downstream of the point at which the blend components are mixed.

[ I claim:] [1.] A fuel dispensing installation comprisinga) first and second fuel tanks containing first and second fuels of differing octane levels,b) conduits from said first and second tanks to a fuel dispenser, said fuel dispenser having a blending system for blending the first and second fuels to form at least one mixture having an intermediate octane, andc) first and second real time octane sensors mounted in the fuel dispenser so as to be in fluid communication with the first and second fuels respectively to sense the octane levels of said first and second fuels and to output signals representative of the octane levels of said first and second fuels to said blending system,wherein the blending system receives the octane sensor output signals and generates output signals to maintain the octane level of the at least one mixture at a predetermined level or within a predetermined range.
