Abstract

A multi-product fuel dispensing system is provided for dispensing a plurality of fuels stored in a plurality of reservoir tanks. A fuel delivery conduit delivers a specific grade of fuel from one or more of the reservoir tanks. The conduit includes at least two flow channels, one for conveying a first grade of fuel and another for conveying a second grade of fuel. A nozzle connected to the conduit includes a blend valve for each flow channel. The nozzle can deliver the first grade of fuel, the second grade of fuel or a third grade of fuel comprising a blend of the first and second grades of fuel. An ultrasonic flow meter is mounted in the nozzle to measure the flow of fuel.
