Reflex glass for level gauges have proved themselves universally where visual process control is essential. A high safety level is secured through the use of borosilicate glass, which has a high chemical resistance and a low thermal expansion. The borosilicate glass is thermal pressured (tempered) so that it can resist to the high pressure and temperature. Reflex glass features a set of V-shaped refractive grooves which when in contact with the liquid and steam in the level gauge work to show the liquid level. The light that enters through the glass is absorbed by the liquid and reflected by the steam (air or gas), which is due to the difference in refractive index of the two medias. The liquid filled portion of the glass will appear black, whilst the space occupied by the steam (air or gas) will appear a silvery-white colour.
