。 An impermeable container that forms a liquid hoistway, a floating body that floats on the liquid surface with a light shielding plate and moves within the container depending on the position of the liquid surface, and detection boxes installed at the upper and lower limit positions of the liquid level. A reflecting plate that receives light that has passed through the container, which is transparent only inside, and reflects the incident light; a light emitting means that irradiates light onto the surface of the reflecting plate through the transparent container; and a light emitting means to the reflecting plate. A light receiving means for receiving a light reception signal by receiving the reflected light irradiated on the surface, and a light detection means for monitoring the light reception signal and detecting the liquid level when the light reception signal is not inputted from the light reception means. Characteristic liquid level meter.
