Level Gauge Glass Types

Choose between reflex and transparent gauge glass depending on your process requirements and visibility needs.

📊 Reflex Gauge Glass

Reflex gauge glass has prismatic grooves molded into the process side. When light passes through, the liquid-filled area appears dark and the vapor space appears bright, providing a sharp, high-contrast level indication without any moving parts.

MaterialBorosilicate 3.3 / Aluminosilicate
Max PressureUp to 40 bar (580 psi)
Max TemperatureUp to 400°C (752°F)
Standard Width30mm / 34mm / 40mm
LengthCustomized (50mm – 2000mm)
Typical ApplicationsBoilers, storage tanks, liquid level indicators

🔎 Transparent Gauge Glass

Transparent gauge glass offers a clear, unobstructed view through the glass, allowing operators to observe fluid color, clarity, interface levels, and the presence of contaminants. Often used in conjunction with a protective shield or mica shield for high-pressure applications.

MaterialBorosilicate 3.3 / Quartz
Max PressureUp to 100 bar (1450 psi)
Max TemperatureUp to 500°C (932°F)
Standard Width20mm / 30mm / 40mm / 50mm
LengthCustomized (50mm – 3000mm)
Typical ApplicationsProcess vessels, sight flow indicators, high-pressure systems

Frequently Asked Questions

Common questions about level gauge glass selection, customization, and applications.

What is the difference between reflex and transparent gauge glass? +
Reflex gauge glass has prismatic grooves on the process side that create a high-contrast level indication (dark for liquid, bright for vapor). Transparent gauge glass is flat and clear, allowing a full view of the fluid, color, and interface. Reflex is typically used for clean liquids where contrast is sufficient, while transparent is preferred for observing fluid properties or when two liquids are present.
Can you manufacture custom lengths and widths? +
Yes, we specialize in custom-cut gauge glass. Provide the required length, width, thickness, and edge finish, and we will manufacture to your exact specifications. We can also match existing glass from your gauge assembly if you provide a sample or drawing.
What materials are available for level gauge glass? +
We offer borosilicate 3.3 (standard), aluminosilicate (for higher thermal shock resistance), and quartz (for extreme temperatures and chemical environments). The material choice depends on your pressure, temperature, and chemical compatibility requirements.
What is the maximum pressure and temperature rating? +
Depending on the type and dimensions, reflex gauge glass can typically handle up to 40 bar and 400°C, while transparent gauge glass (with borosilicate or quartz) can handle up to 100 bar and 500°C. Quartz can go up to 800°C in low-pressure applications. Please share your process conditions for a specific recommendation.
Do you provide OEM gauge glass manufacturing? +
Yes, we provide OEM manufacturing services including custom dimensions, edge treatments, polishing, and special packaging. We work with equipment manufacturers and distributors worldwide.
How do you package gauge glass for shipment? +
Gauge glass is carefully wrapped with protective foam and placed in reinforced wooden crates or sturdy export cartons. We ensure that each piece is separated to prevent scratching or breakage during international transit.
