MEASURING DEVICE, CLEANING DEVICE, AND RADIOACTIVE WASTE SOLIDIFYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a measuring device capable of stably measuring a liquid level in a liquid tank.SOLUTION: A measuring device measures a liquid level in an internal space of a liquid tank. The measuring device includes: a measuring member that connects with the internal space via a flow channel and forms a measuring space into which a liquid in the internal space flows; a liquid sensor capable of detecting the surface of the liquid in a measuring space in a non-contact manner; and an air flow generating device that generates the flow of air in a space so that a liquid in the space between the liquid sensor and the surface of the liquid in a measuring space recedes from the space.
