Abstract
A void fraction sensor for measuring a void fraction of a cryogenic liquid includes a pipe having a conduit in which the cryogenic liquid flows, and an electrode provided on the outer peripheral surface of the pipe to measure capacitance of the cryogenic liquid flowing in the conduit. The pipe is composed of an even number of dividable ceramic members, and among the even number of ceramic members, at least two ceramic members facing each other are each provided with the electrode.

A void fraction sensor for measuring a void fraction of a cryogenic liquid, comprising:
- a pipe having a conduit in which the cryogenic liquid flows;
- and
- an electrode provided on an outer peripheral side of the pipe to measure capacitance of the cryogenic liquid flowing in the pipe, wherein
- the pipe is composed of an even number of ceramic members that are dividable, and among the even number of ceramic members, at least two ceramic members facing each other are each provided with the electrode.
A void fraction sensor for measuring a void fraction of a cryogenic liquid, comprising:
- an inner pipe having a conduit in which the cryogenic liquid flows;
- an outer pipe covering an outer periphery of the inner pipe;
- and
- an electrode disposed outside the inner pipe for measuring the void fraction of the cryogenic liquid flowing in the conduit, wherein
- the inner pipe is composed of an even number of dividable ceramic members, and among the even number of ceramic members, at least two ceramic members facing each other are each provided with the electrode.
