Study and application of directional technology of mass method flow measurement system for cryogenic liquid
The physical property of cryogenic liquid caused it easy to evaporation.Measuring the mass flow of cryogenic liq-uid was a technical problem.This paper focused on the application of cryogenic liquid flow measurement system,and presented a test method in the case of the reduction of flow measurement system evaporation as far as possible.The using high pressure gas directional device for cryogenic liquid was designed.Liquid nitrogen was used as test medium of to verify the availability of the method and the directional device.The improvement measures for accurate measurement were obtained.Those datas and im-provement measures are technical means for the research of the measurement performance of various types of flow meters for ap-plying to cryogenic liquid.
