LNG Bunkering 적산 기술에 대한 기초 비교 연구

Abstract

An increase in the trade of LNG also means an increase in the custody transfer and fiscal metering points for gas in cryogenic conditions. Tank gauging has been a popular measurement method for LNG, but it has its limitations and increased demand for very accurate flow measurements can be observed. The development, construction and calibration of an ultrasonic flowmeter for custody transfer of LNG is, however, not simple taking into account the very low temperatures and the limitations regarding the calibration under reference conditions.demand for very accurate flow measurements can be observed.
