Abstract
Disclosed is a cryogenic liquid storage apparatus including a storage container configured to accommodate a cryogenic liquid, a housing member provided in the storage container and configured to define a vacuum space spatially separated from an internal space of the storage container, and a temperature sensor provided in the vacuum space so as to be in contact with an inner surface of the housing member and sense a signal to detect a liquid level of the cryogenic liquid.
Claims18
A cryogenic liquid storage apparatus including:
- a storage container configured to accommodate a cryogenic liquid;
- a housing member provided in the storage container and configured to define a vacuum space separated from an internal space of the storage container;
- and
- a temperature sensor provided in the vacuum space so as to be in contact with an inner surface of the housing member and configured to sense a signal to detect a liquid level of the cryogenic liquid,
- wherein the storage container comprises:
- an inner container configured to accommodate the cryogenic liquid;
- an outer container that surrounds the inner container;
- and
- a vacuum thermal insulation layer defined between the inner container and the outer container, and
- wherein the vacuum space communicates with the vacuum thermal insulation layer.
A liquid level measurement device for measuring a liquid level of a cryogenic liquid accommodated in a storage container, the liquid level measurement device comprising:
- a housing member provided in the storage container and configured to define a vacuum space separated from an internal space of the storage container;
- and
- a temperature sensor provided in the vacuum space so as to be in contact with an inner surface of the housing member and configured to sense a signal to detect a liquid level of the cryogenic liquid,
- wherein the storage container comprises:
- an inner container configured to accommodate the cryogenic liquid;
- an outer container that surrounds the inner container;
- and
- a vacuum thermal insulation layer defined between the inner container and the outer container and communicating with the vacuum space.
