Abstract
A cryogenic liquid sampler is provided. The sampler includes an inner volume and a useful internal length, a cryogenic liquid inlet conduit in fluid connection with an inlet valve, a weir tube in fluid connection with the inlet valve, wherein the weir tube comprises at least one weir hole, wherein the weir tube extends a predetermined distance into the inner volume, a cryogenic liquid outlet conduit in fluid connection with inner volume and in fluid connection with an outlet valve, and a purge tube in fluid connection with the outlet valve.
Claims10
A cryogenic liquid sampler comprising:
- a sampler vessel comprising an inner volume and a useful internal length,
- a cryogenic liquid inlet conduit in fluid connection with an inlet valve,
- a weir tube in fluid connection with the inlet valve and the inner volume, wherein the weir tube comprises a distal end within the inner volume, at least one weir hole through a circumferential surface of the weir tube and proximate the distal end, and a weir tube top plug which seals a distal opening of the weir tube, wherein the weir tube extends a predetermined distance into the inner volume,
- a cryogenic liquid outlet conduit in fluid connection with the inner volume and in fluid connection with an outlet valve, and
- a purge tube in fluid connection with the outlet valve,
- wherein the weir tube has an outside diameter of Dwt wherein the at least one weir hole has a generally circular shape and a diameter of Dwh, and wherein Dwh/Dwt is between ¼ and ½.
