Reflex gauges have a single vision slot in which light can enter the gauge chamber to determine liquid level. Above the liquid level, glass prisms reflect the surrounding light. Below the liquid level the liquid fills the prisms causing the glass to become relatively transparent. 

Light striking the area of glass covered by transparent liquid is allowed to pass through to the interior of the gauge along the entire length of the covered prism. The light is reflected from the back of the chamber to the observer. Typically the chamber appears dark. An opaque liquid such as milk would directly reflect the light at the surface of the prisms, where it appears as a solid column of white. 

Light striking the area of the glass above the liquid level experiences internal reflection. Internal reflection will occur when light attempts to move from a medium having a given index of refraction to one having a lower index of refraction. 

When the light attempts to move from a higher index of refraction (glass – 1.47 index of refraction) to a lower index of refraction (air – 1.00 index of refraction through the prism angle), it reflects rather than passes through to the back of the chamber. Except for a focused line of light along the apex of the prism, the surrounding light reflects back to the observer appearing silvery. 

The interface between the liquid and gas occurs where the silvery and dark/opaque area intersect.
