Liquid level detecting device, refrigeration cycle device having the same, and liquid level detecting method

摘要

A liquid level detection device according to the present invention is a liquid level detection device that detects the liquid level of a container in which a fluid is stored, and is positioned at different heights on the outer surface of the container in a state where the fluid flows into the container A temperature measurement unit that measures temperatures at a plurality of locations, and a liquid level detection unit that detects a liquid level according to the flow velocity distribution.
