Fuel blending using blend component octane levels
First Claim
1. A fuel dispensing installation comprisinga) first and second fuel tanks containing first and second fuels of different octane levels,b) first and second octane level sensors mounted in the first and second fuel tanks respectively for measuring fuel octane levels and generating output signals indicative of the octane levels of the first and second fuels;
- c) conduits from the first and second tanks to at least one fuel dispenser, the at least one fuel dispenser including a blending system for blending the first and second fuels to form at least one blended fuel having an intermediate octane, andd) a site controller in electronic communication with the blending system for receiving the output signals and controlling the blending system to permit the dispensing of the at least one blended fuel based on the measured octane levels of the first and second fuels.

Abstract
A fuel dispensing installation that includes first and second fuel tanks containing first and second fuels of different octane levels. The tanks are provided with first and second octane level sensors mounted in the first and second fuel tanks respectively for measuring fuel octane levels and generating output signals indicative of the octane levels of the first and second fuels. Conduits from the first and second tanks transport the fuel to one or more fuel dispensers. The fuel dispensers include a blending system for blending the first and second fuels to form at least one blended fuel having an intermediate octane. A site controller in electronic communication with the blending system receives the output signals and controls the blending system to permit the dispensing of one or more blended fuels based on the measured octane levels of the first and second fuels.

11. A method for controlling the blending of a low octane fuel and a high octane fuel to create at least one blended fuel grade or at least one non-blended fuel grade comprising:
-
a) determining inside a first tank the actual octane level of the low octane fuel source therein; b) determining inside a second tank the actual octane level of the high octane fuel source therein; c) comparing the actual octane levels determined in steps a) and b) to predetermined levels for each fuel source to determine if the difference between the actual levels and predetermined levels are within predetermined limits; d) determining the amount of each said high and low fuel source required to create at least one blended or at least one non-blended fuel grade based on the results of the comparison of step c); and e) permitting the dispensing of each blended fuel grade and non-blended fuel grade that the result of comparison of step c) indicates may be created. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for controlling the blending of a low octane fuel and a high octane fuel by a fuel dispenser blending system to create at least one blended fuel grade comprising:
-
a) determining inside a first tank the actual octane level of the low octane fuel therein; b) determining inside a second tank the actual octane level of the high octane fuel therein; c) comparing the actual octane levels determined in steps a) and b) to predetermined levels for each fuel source to determine if the difference between the actual levels and predetermined levels are within set limits; d) providing the results of comparison of step c) to the fuel dispenser blending system; and e) modifying the operation of the blending system as needed depending on the results of step d).
