LIQUID LEVEL DETECTOR OF CRYOGENIC LIQUID STORAGE CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a liquid level detector in a cryogenic liquid storage container permitting long-term stable level detection. SOLUTION: The liquid level indicator is composed of capacitance type water gauge 2 to be irruptively-located into an adiabatic storage container 1 storing cryogenic liquid, making a gas vent hole 12 of this capacitance type water gauge 2 on a gas phase section 14 inside the container.
