1. Multiport Bicolor Gauges: Advanced Visibility & Reliable Performance
Key Features:

• Rugged & Robust Design – Built to withstand extreme boiler conditions, ideal for high-pressure applications with extended durability.
• Dual-Color Display – Red for steam, green for water enable quick differentiation and unmistakable level indication
• Enhanced Visibility – Equipped with LED illumination for easy reading even in low-light conditions.
• Superior Protection – Mica sheet protection prevents glass erosion from steam and water.
• Easy Maintenance – Individual port assembly allows quick installation and hassle-free glass replacement.
• Customization & Compliance – Available in customized center-to-center distances with IBR certification.

Applications:

Widely used in boiler drum applications, Multiport Bicolor Level Gauges are best suited for medium- to high-pressure boilers, offering direct and precise liquid level indication.

Advantages:

• Superior visibility from any distance and location.
• Minimal human error with intuitive dual-color indication.
• Enhanced safety & compliance with industry standards.

Limitations: 

• Level between ports is not directly visible. 
• Visibility may be affected by steam condensation or contamination.

2. Transparent Gauges: Clarity & Versatility

Key Features:

• Dual flat glasses on either side provide direct liquid visualization.
• High-Pressure Resistance – Ideal for monitoring water/steam at high temperatures and pressures.
• Mica Sheet Protection – Prevents glass erosion from steam and water.
  Optional Illuminator – Improves visibility in low-light environments.

Applications:

Commonly used in boiler drum applications, transparent gauges are suitable for medium-pressure boilers that require direct liquid level indication.

Advantages:

• Durable and rugged for high-temperature and pressure applications.
• Direct liquid visualization enhances monitoring accuracy.
• Suitable for colored, colorless, and interface liquid level measurement.

Limitations:

• Visibility may be affected by steam condensation or contamination.

 3. Reflex Gauges: Simplicity & Cost-Effectiveness

Key Features:

• Prismatic Glass Design – Uses light reflection to differentiate liquid and vapor phases.
• Distinct Level Indication – Liquid appears dark, while vapor/steam appears silvery white.

Applications:

Widely used in low- to medium-pressure applications, reflex gauges offer a cost-effective solution for liquid level indication.

Advantages:

• Robust and durable for industrial use.
• Direct and clear liquid indication.
• Economical compared to transparent and multiport bicolor gauges.

Limitations:

• Not suitable for colored or interface liquids.
• Not recommended for high-pressure applications.
