Abstract
The invention relates to a method and apparatus for dispensing and metering a fluid, particularly fuel, from a plurality of fluid sources to a single or a plurality of fluid outlets. The invention uses a single meter for measuring the amount of fluid dispensed from each of the fluid outlets. Valves are used at the inlet to and outlet from the meter to control the flow of fluid from a single source to a single outlet intended to dispensing fluid from the selected source. The invention is particularly useful in a multiple grade or octane-level fuel pump or dispenser. The meter can advantageously be located near the dispensing nozzles, so that the contamination caused by using a single meter is purged after a small amount of fuel is dispensed. The invention preferably uses a small-volume meter with valves located near the meter, to thereby limit the amount of octane variation caused by use of a single meter.
