Archon Transparent & Reflex Flat Glass Liquid Level Gauges

Other Recommended Products:
Additional Information

Archon Transparent and Reflex Flat Glass Liquid Level Gauges, available on BoilerSupplies.com, are designed to offer high visibility and accuracy for monitoring liquid levels in industrial applications. Here’s an overview of their key features and specifications:

Key Features:

  1. Construction and Durability:

    • Made from solid bar stock of cold-rolled carbon steel, stress-relieved, and assembled with drop-forged steel covers.
    • Equipped with tempered borosilicate glasses that resist thermal shock, heat, corrosion, and abrasion​​​​.
    • Available in other special metals like stainless steel and Monel for specific applications​​​​.

  2. Types of Gauges:

    • Transparent Gauges: Feature two pieces of glass on opposite sides of the chamber. These are useful for observing the actual liquid characteristics and for liquid-liquid interface applications. Mica shields can be used to protect the glass in steam environments, while Kel-F shields are recommended for corrosive environments​​.
    • Reflex Gauges: Use flat Reflex Glass with reflecting prisms, causing the liquid to appear black and the space above it silvery, providing a distinct reading of the liquid level. These are suitable for high-pressure applications and ensure clear visibility of the liquid level​​.

  3. Pressure and Temperature Ratings:

    • High-pressure models are designed to handle rigorous conditions with precise pressure and temperature ratings detailed in their specifications.
    • Models are available in various sizes and configurations to fit specific industrial needs, with sections ranging from 1 x 1 to 10 x 9, accommodating different visible lengths and overall dimensions​​​​.

  4. Installation and Maintenance:

    • The liquid chambers are recessed for each individual glass, ensuring the gasket fits snugly and cannot be forced out by internal pressure. This design enhances durability and reliability.
    • Standard gaskets are made from compressed non-asbestos material, but can be furnished in other materials suitable for specific liquids​​​​.

In-stock orders eligible for small-pack shipments placed before 2:00 PM EST, Monday through Friday, will ship the same day. If ordered after 2:00PM EST, it will ship the following business day.
