Abstract
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.
