Made of borosilicate glass, Transparent Gauge Glass is used in numerous applications where both chemical resistance and low thermal expansion coefficient are required. For FLAT level indicators, a two-sided observation system is used, as direct observation through the glasses is allowed as the fluid rises or falls. These are mainly used in processes where the color of the liquid is of high importance for the process or applications that require a protective mica.
High-pressure transparent level gauge glasses serve as an indispensable tool in environments where monitoring the exact level of fluids under high pressure is critical.
Unlike their reflex counterparts, these gauges employ two pieces of flat, transparent glass mounted on opposite sides of a tank or vessel, allowing operators to observe the fluid level directly. This design is particularly advantageous in applications where it is essential to view the characteristics of the fluid itself, such as color, clarity, and the presence of any sediments or separations.
The straightforward, yet effective, visibility provided by these gauges makes them a key component in maintaining operational safety and efficiency, ensuring precise fluid management in even the most demanding industrial settings.

For transparent level indicators, a two-sided observation system is used; direct observation through the crystals is allowed as the fluid rises or falls. These are mainly used in processes where the color of the liquid is of high importance for the process, or applications which require a protective mica.
In order to achieve the standardization of this type of sight glass across industries, the German regulatory institute DIN established standard parameters for manufacture. Among the main characteristics of this regulation are the dimensional parameters, pressure resistance, chemical composition, characteristics of the glass and viewing surfaces, tolerance parameters regarding parallelism, and the necessary acceptance tests.
