Flowmeter for two-phase gas/liquid cryogenic fluids

摘要

The invention relates to a flowmeter for two-phase gas/liquid cryogenic fluids, comprising: a liquid/gas phase separator, preferably consisting of a tank (1), into the top part of which the cryogenic liquid is admitted; a liquid flow-rate sensor (21), located in a liquid duct in fluid communication with the bottom part of the tank, the tank being placed in a high position (H) in space relative to the liquid flow-rate sensor (21); a gas duct, in fluid communication with the top part of the tank, equipped with a gas valve (12); and a device for measuring the level of liquid in the tank, preferably comprising two level sensors: a lower level sensor (3) and an upper level sensor (2).
