Abstract
A void fraction sensor according to the present disclosure includes an insulating pipe having a through hole through which a cryogenic liquid flows, and a pair of planar electrodes mounted on an outer wall surface of the insulating pipe. The insulating pipe has electrode mounting portions at which a distance D1 between inner wall surfaces in a direction perpendicular to electrode surfaces of the pair of planar electrodes is shorter than a distance D2 between inner wall surfaces in a direction parallel to the electrode surfaces of the pair of planar electrodes.
