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