A liquid level gauging system and sensor device for installation in the aperture of a wall of a liquid-con- taining vessel, including a metal fitting having a through bore and a substantially cylindrical body por- tion with external threads by which it can be secured in the aperture in the vessel wall, a cup-like enclosure disposed in the bore, the enclosure having a bottom wall containing a prism disposed adjacent the inner end of the bore, and a light source and a light-responsive de- vice mounted in the enclosure. The prism has a substan- tially conical forward end portion for immersion in the liquid to be monitored. The conical forward end portion of the prism is characterized by an axis, and the prism has a light-admitting and light-transmitting conical recess coaxial with the conical end portion of the prism. Light rays from the source that pass into the surface of the conical recess are bent, by refraction, toward the conical end portion. Reflected rays from the conical end portion passing outwardly through the surface of the conical recess are similarly bent, by refraction, toward the light-responsive means. The advantage of the present invention is that especially high resolution and accuracy are possible, while maintaining good reliability and repeatability.
