特徴と゛する光液面計測装置。The shape of the container for storing a transparent liquid is such that a transparent circular tube installed along the outer surface of the container is joined to a hole penetrating inside and outside from the bottom side of the container, and the liquid contained in the container is formed into a transparent circular tube. In a container structure formed as if connected to a pipe and equipped with a general visible liquid level gauge, a transmission-type photoelectric switch is disposed at any vertical position of the transparent circular pipe, The photoelectric switch emits parallel light from the side of the transparent circular tube from the light emitting section, and blocks the amount of light that has passed through the transparent circular tube.□ A small pinhole-shaped hole drilled in the light plate is passed through the light receiving section. It is configured to be exposed to light, and light is received by increasing or decreasing the amount of light within the small hole of the light shielding plate, which is caused by the refraction state of the light beam in the transparent circular tube section, which changes depending on the presence or absence of liquid in the transparent circular tube at the light emitting position of the photoelectric switch. An optical liquid level measuring device characterized in that the liquid level position in the container is measured by a switch function activated in response to a part.
