摘要

PROBLEM TO BE SOLVED: To inexpensively and accurately measure liquefied natural gas in a liquid state. SOLUTION: A liquefied gas metering device 14 vaporizes a liquefied gas into a vaporized gas, a liquefied gas temperature of the liquefied gas flowing into the vaporizer, and a vaporized gas of the vaporized gas flowing out from the vaporizer. The measuring means 44 for measuring the liquefied gas amount of the liquefied gas based on the temperature and the amount of heat supplied from the heat medium for vaporizing the liquefied gas in the vaporizer.
