1. A multiproduct fuel dispensing system for dispensing a plurality of grades of fuel comprising:
- a plurality of reservoir tanks;
a fuel dispenser;
each reservoir tank having a fuel reservoir line connected to deliver a specific grade of fuel from a specific one of the reservoir tanks to the fuel dispenser;
a single fuel delivery conduit connected at a first end to an intersection of each of the fuel reservoir lines, and connected at a second end sequentially to a single ultrasonic flow meter, an outlet casting and a delivery hose; and
the single ultrasonic flow meter connected immediately adjacent to the outlet casting for measuring the amount of any of the grades of fuel flowing to the delivery hose.

Abstract
A multiproduct fuel dispensing system for dispensing a plurality of fuels stored in a plurality of reservoir tanks. A single fuel delivery conduit delivers a specific grade of fuel from the reservoir tanks. An ultrasonic meter is in the conduit and uses sing-around measurement to measure flow through the meter. The meter has a volume of about 10 cubic centimeters and a flow rate of about 10 gallons per minute. The meter may stand alone in the conduit or may be integrally formed with an outlet casting in the conduit.

19. A system for dispensing a plurality of fuels stored in a plurality of sources, respectively, the system comprising a conduit extending from each source, a valve associated with each conduit for controlling the flow of fluid through the conduit, a single fuel delivery line connected to a convergence of all of the conduits for receiving fluid from one or more of the conduits, a control device for selectively controlling each valve so that fluid flows from a selected one of the sources, through its corresponding conduit and to the single fuel delivery line, and sequentially to an ultrasonic flow meter, an outlet casting, a single fuel delivery hose, and a dispensing nozzle, the flow meter including a pair of transducers for transmitting ultrasonic pulses through the fluid in the meter and for receiving the pulses to enable the velocity of the fluid passing through the meter, and therefore the amount of dispensed fluid through the nozzle, to be determined.
