Abstract: A very promising alternative to the state-of-the-art static volume measurements for Liquid Natural Gas (LNG) custody transfer processes is the dynamic principle of flow metering. In the frame of the Joint Project Research METROLOGY for LNG, CESAME EXADEBIT explored a novel cryogenic flow metering technology using Laser Doppler Velocimetry (LDV), as alternative to ultrasonic and Coriolis flow metering. The study focused on the technological challenges and solutions for extending the LDV method to cryogenic temperatures, and on the estimation of the uncertainty that can be realistically achieved with such a measurement system to measure the LNG flowrate
