A multiproduct fuel dispensing system (26) for dispensing different grade fuels stored in several reservoir tanks (32a, 33b). Several fuel delivery conduits (44a, 44b) deliver a specific grade of fuel from one or more of the reservoir tanks (32a, 33b). Plural ultrasonic metering orifices (18a, 18b) are mounted in a single housing (30a) with shared electronic circuitry, and use sing-around measurement to measure flow. Each of the meters (30a, 30b) has volume of about 50 cubic centimeters and a flow rate of about 10 gallons per minute. The housing (30a, 30b) is connected to the conduits (34, 35) to permit measurement of fuel flow through each meter (18a, 18b, 20a, 20b). |
