Reflex Level Gauge Glass: Tempered Borosilicate Glass for Liquid Level Measurement

Clear Level Indication for Industrial Equipment

Reflex level gauge glass is a type of sight glass used in level gauges to observe the liquid level inside tanks, boilers, pressure vessels, and other industrial equipment.

It is made from tempered borosilicate glass, offering good thermal shock resistance, mechanical strength, and chemical durability. The glass surface is specially processed with a prismatic or grooved pattern that helps create a clear contrast between the liquid and gas phases.

What Is Reflex Level Gauge Glass Also Called?

Depending on the industry or equipment supplier, it may also be called:

· reflex gauge glass

· reflex sight glass

· reflex level gauge glass

· reflex level gauge sight glass

· tempered borosilicate level gauge glass

· prismatic level gauge glass

These terms generally refer to glass designed for use in reflex-type liquid level gauges.

How Does Reflex Gauge Glass Work?

The working principle is relatively simple.

The grooved surface of the glass reflects light differently depending on whether the area is in contact with liquid or vapor. This creates a visible contrast, allowing operators to identify the liquid level quickly.

Compared with a plain transparent sight glass, the reflex design provides a more obvious level indication in many industrial applications.

Why Use Tempered Borosilicate Glass?

Borosilicate glass is widely used for level gauge applications because of its low thermal expansion and good resistance to sudden temperature changes.

After tempering, the glass has improved mechanical strength, which is useful when the gauge is exposed to pressure, vibration, or other demanding operating conditions.

Typical applications include:

· Boilers and steam equipment

· Storage tanks

· Pressure vessels

· Chemical processing equipment

· Oil and gas equipment

· Industrial liquid level gauges
