徴とする液面計。 A device that reflects light from a light source on a flat plate and receives it on a light receiving element is installed longer above the liquid surface than in the liquid, and takes advantage of the difference between the refractive index of light in the air and the refractive index of light in the liquid. A liquid level gauge that measures the height of a liquid level by converting changes in the resistance of a light-receiving element into optical or electrical signals.
