With the rapid development of LNG vehicles in China, LNG stations are increasing in such great numbers that LNG dispensers are more and more widely used. Hereby this paper first introduces the structure compositions, working principles, and flow process of an LNG dispenser. Then, through an analysis of the market and technical status of LNG dispensers in China, it is pointed out that the Coriolis mass flowmeter is high in price and single and double flowmeters coexist in the present market, and the developing trend of LNG dispensers in China is also predicted as follows: (1) Coriolis mass flowmeters will be hopefully made in China; (2) Single flowmeters will be developed for LNG dispensers; (3) Compulsory verification will be done on the LNG dispensers; (4) LNG dispensers will be put into industrial production. This developing direction will help this industry in China promote the technical level of LNG dispensers and occupy more shares in both domestic and foreign markets.
