Abstract (en)
[origin: CA2927878A1] The invention relates to a flowmeter for liquid/gas two-phase cryogenic fluids, including: a separator (1) of the liquid/gas phases, preferably made up of a vessel, the cryogenic fluid being admitted into the top portion of said vessel; a liquid flow sensor (3), located on a liquid pipe (2) in fluid communication with the bottom portion of the vessel, the vessel being placed in the top position in the space relative to the liquid flow sensor; a gas pipe (4), in fluid communication with the upper portion of the vessel, provided with a flow sensor (5) of the gas phase circulating in said gas pipe; a three-way valve (6) capable of recovering, in two of the channels thereof (A/B), the downstream end of said gas pipe and the downstream end of said liquid pipe; and a device for measuring the level of liquid in the vessel (7), preferably comprising two level sensors: a bottom level sensor and a top level sensor.
