Introduction
Level gauge glasses are essential components for monitoring liquid levels in industrial tanks, boilers, and pressure vessels. Choosing the right level gauge glass ensures accurate readings, durability, and chemical resistance.
In this guide, we’ll explore the 6 best level gauge glasses for tanks, including Aukimica Industrial-Grade Mica Sight Glass Level Gauges, known for their exceptional thermal resistance and longevity.
What Is a Level Gauge Glass?
A level gauge glass is a transparent or semi-transparent glass panel used in industrial equipment to monitor liquid levels inside tanks, boilers, or processing systems. It provides real-time visibility of liquid levels, ensuring safety and process efficiency.
These glasses must withstand high temperatures, pressure, and chemical exposure, making material selection crucial.
Types of Level Gauge Glasses
There are several types of level gauge glasses, each suited for different applications:
- Reflex Glass – Features grooves for enhanced visibility of liquid levels.
- Transparent Glass – Clear glass used with external illumination for visibility.
- Mica Glass – High-temperature and corrosion-resistant, ideal for steam applications.
- Borosilicate Glass – A heat-resistant, chemically stable glass for general industrial use.
- Quartz Glass – High-purity glass for extreme temperature applications.
- Tubular Sight Glass – A cylindrical tube used for direct liquid level monitoring.
Key Considerations When Choosing a Level Gauge Glass
To select the best level gauge glass for your application, consider:
- Temperature Resistance – Ensure it can withstand extreme heat (e.g., mica glass up to 1000°C).
- Pressure Rating – Choose glass designed for your system’s maximum operating pressure.
- Chemical Compatibility – Select materials resistant to the liquids and chemicals in your tank.
- Durability – Look for materials with high impact and thermal shock resistance.
- Visibility Requirements – Reflex vs. transparent glass depends on how you want to view the liquid level.
