Compare the difference in application between Reflex gauge glass and Transparent gauge glass

AOHONG Company through the development of reflex and transparent gauge glasses with its innovative approach, manufactures both types to cater to a wide range of industrial needs.

Reflex gauge glasses are favored for their easy readability in moderate conditions, transparent gauge glasses offer direct observation and are preferred in more extreme environments.

Each type serves different applications based on the unique advantages they offer.

Reflex Gauge Glass: The primary feature of reflex gauge glass is the presence of grooves on the side of the glass that faces the medium being measured. These grooves refract light, giving the liquid level a distinctive, highly visible appearance. In the presence of a liquid, the glass appears to be solid due to the refracted light, while in the absence of a liquid, the glass appears to be clear. This provides a stark contrast, making it easier for operators to read the liquid level. Reflex gauge glasses are commonly used in applications where the visibility of the liquid level is crucial, and the pressure and temperature conditions are relatively moderate.

Transparent Gauge Glass: Unlike reflex gauge glasses, transparent gauge glasses are simply clear, high-strength glass panels. They allow the operator to visually inspect the interior of the vessel or boiler, providing a more direct observation of the liquid level. To enhance visibility, transparent gauge glasses are often used with mica shields or protective coatings to prevent damage from the hot, corrosive environment. These gauge glasses are ideally suited for high-pressure, high-temperature applications where direct visual inspection of the boiler or vessel interior is necessary.
