Abstract
A liquefied gas metering apparatus for use with liquefied gas dispensing equipment which conveys liquefied gas from a supply to a dispensing point and metering means (17). The metering apparatus has sensing means (50) to sense a measurable parameter of the liquefied gas related to the density of the liquefied gas particularly an electrical parameter such as the dielectric constant and to generate a sensing signal (77) indicative of the sensed parameter. The sensing means (50) includes a capacitive device (56) comprising spaced capacitor plates (71, 72) arranged to be immersed in the liquefied gas. Calculating means (76) is responsive to the sensing signal. The calculating means (76) being operative to control operation of the metering means (17) by compensating the determination by the metering means (17) of the metered liquefied gas dispensed during a dispensing operation for changes in gas composition.
