Abstract
A multi-product fuel dispensing system includes a plurality of reservoir tanks. Each tank has a specific grade of fuel stored therein. Each reservoir tank has a fuel delivery line connected thereto. A fuel delivery conduit has at least two flow channels. One flow channel is connected to receive a first grade of fuel from one of the fuel delivery lines, and another flow channel is connected to receive a second grade of fuel, of a lower grade than the first grade, from another of the fuel delivery lines. A nozzle has a connection to receive fuel from the fuel delivery conduit. A first proportional flow control and blend valve is connected in the system for receiving the first grade of fuel. A second proportional flow control and blend valve is connected in the system for receiving the second grade of fuel. A meter is connected in the system for receiving the second grade of fuel. An ultrasonic flow meter is mounted adjacent the nozzle and fuel delivery conduit connection for measuring the flow of fuel through the nozzle.
