Fuel nozzle dispenser using ultrasonic metering
First Claim
1. A multi-product fuel dispensing system comprising:
- a plurality of reservoir tanks, each tank having a specific grade of fuel stored therein, each grade being different from each other grade;
each reservoir tank having a fuel delivery line connected thereto;
a fuel delivery conduit having at least two flow channels, one flow channel connected to receive a first grade of fuel from one fuel delivery line, and another flow channel connected to receive a second grade of fuel, of a lower grade than the first grade of fuel, from another fuel delivery line;
a nozzle having a connection to receive the first and second grades of fuel from the fuel delivery conduit;
a first proportional flow control and blend valve connected in the system for receiving the first grade of fuel;
a second proportional flow control and blend valve connected in the system for receiving the second grade of fuel;
a first meter connected in the system for receiving the second grade of fuel; and
an ultrasonic flow meter mounted adjacent the nozzle and fuel delivery conduit connection for measuring the flow of the fuel through the nozzle.

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.
