Title:
VOID FRACTION SENSOR, FLOWMETER EMPLOYING SAME, AND CRYOGENIC LIQUID TRANSFER TUBE
Document Type and Number:
WIPO Patent Application WO/2022/163779
Kind Code:
A1
Abstract:
A void fraction sensor according to the present disclosure is provided with an insulated tube having a through hole for allowing a cryogenic liquid to flow, and a pair of planar electrodes mounted on an outer wall surface of the insulated tube. The insulated tube has an electrode mounting portion of which a distance D1 between inner wall surfaces in a direction perpendicular to the electrode surface of the electrodes is less than a distance D2 between the inner wall surfaces in a direction parallel to the electrode surface of the electrodes.
