An octane sensitive blending dispenser for fluids, particularly for fuel dispensers. The dispenser controls component pumps according to octane data measured by octane meters. In one form of the invention octane measurements are taken within the input lines connected to the dispenser from fluid storage tanks. Control of the component pumps is accomplished by determining the difference between the desired blend octane and the observed blend octane and adjusting the pumps so as to more closely blend the desired fluid.

[ What is claimed is:] [1.] A dispenser for blending component fluids to achieve a desired octane for the blended product, said dispenser comprising:a plurality of fluid conduits, each said fluid conduit coupled to one of at least two supplies of component fluid to be dispensed therefrom;a pump means coupled to each said fluid conduit for controlling the flow rate at which each said component fluid flows through said respective fluid conduits;octane sensors operatively associated with said fluid conduits for measuring the octane of said component fluid flowing through each said fluid conduit and for providing an octane signal representative of said octane;an output means coupled to each said fluid conduit for mixing and dispensing said component fluids; andcontrol means for controlling the blending and dispensing of said component fluids, said control means coupled to said octane sensors means and said pump means, said control means including selecting means for selection of said desired octane blend and comparison means for comparing a calculated octane with said desired octane and for determining a corrected blend ratio, said control means further including adjustment means for adjusting said pump means in accordance with said corrected blend ratio such that the actual octane of dispensed blended fluids is substantially equal to said desired octane.
