    Product Instruction
    B49H series bicolour quartz tube level gauge is kind of liquid level product based on optical principle,which consists of high purity quartz glass tube.
    There is a great contrast between liquid and gas, and it is clear in long-distance observation and night.
    It successfully overcomes the shortcomings of ordinary plate level meter, such as bulky, large sealing area, easy leakage, unclear display and difficult color observation at close range.
    There are standard type, insulation type (insulation tube installed in stainless steel jacket), anti-corrosion type (sprayed PTFE film), full range type without blind area, and lighting equipment can be installed at the same time to facilitate use at night or in places with poor light.


    Operating Principle
    In the aspect of liquid level meter display, it use of the principle of reflection and refraction of light, and adopt special structure and technology to design and manufacture.When the two-color liquid level meter is installed on various measuring containers, the change of liquid level can be observed directly, the liquid phase display is green, the gas phase display is red, and the interface measurement is trichromatic interface.

    Structure diagram of dual color quartz tube

    1. Clear indication, good sealing.
    2. High working temperature and pressure: <= 500℃,<=10MPa
    3. Quartz tube level gauge has long lifetime, simple structure, easy cleaning and maintenance
    4. Self-enclosed design.
    There are two steel ball in the valve at the both sides. When quartz tube happened to explosion, Steel balls can automatically block channel to avoid liquid flow away if the pressure difference between inside and outside is above 0.3Mpa.
