Reflex vs Transparent Level Gauges

When it comes to monitoring the level of liquids in tanks and other containers, there are two main types of gauge glasses to consider: reflex and transparent.

Reflex level gauges utilize a prismatic groove to reflect light off the surface of the liquid, which is then viewed by the observer to determine the level. These gauges are best suited for use with colorless liquids, as the light will not be reflected back to the viewer and the chamber will become dark. However, reflex gauges may not be as effective for use in interface applications, as they cannot clearly distinguish between two different liquids and may simply appear dark when the chamber is filled with liquid.

Transparent level gauges, on the other hand, allow the observer to directly view the level of the liquid through a window made of glass. These gauges are well-suited for use in interface applications and with liquids that are not colorless. They are also generally more resistant to corrosion and can withstand higher temperatures and pressures than reflex gauges.

In general, transparent level gauges are considered the default choice for most applications, as they are able to perform all the functions of reflex gauges and more. However, it is important to carefully evaluate the specific needs of your application before making a decision, as both types of gauges have their own strengths and limitations.
