No blind area two color quartz glass tube level gauge is suitable for high temperature and high pressure environment of a two-color display of the level indicator, this level indicator in the display of gas, liquid into a significant red and green two-color, the level indicator through the two ends of the upper and lower flange of the Cauchy and the vessel being measured connected to the measurement of the different colors of the gas, liquid, you can intuitively observe the position of the liquid level, there will be no vapour in the glass tube to affect the observation of results of the phenomenon. 

 No blind area two color quartz glass tube level gauge after adding the elbow his centre distance = visual range, to achieve the detection of no blind spot, can be more effective observation of the liquid level in the container, to avoid economic losses and accidents caused by the water level gauge is too high or too low and can not be observed.

Product Features

• Able to carry out long-term stable level measurement under the high temperature environment of 600℃.
• Can be in the 10Mpa high-pressure environment for long-term stability of the liquid level measurement work.
• Red and green dual-colour display, can be more convenient to distinguish between liquid level and vapour level.
• With self-closing function, when the liquid level meter is broken due to accident, it can effectively avoid economic loss and personnel injury.
• The quartz glass tube of the liquid level meter is surrounded by a protective shell, which can effectively protect the glass tube from being damaged by external forces.
• Simple installation and easy maintenance.

Why use glass level gauge

Glass level gauges have been in use for over 100 years. They give you the ability to directly view the process fluid under temperature/pressure conditions that would render most other level technologies useless.Their construction is very robust, and reliable. They define the term “simple to use”.  After installation, the only tool you will need is your eyes. Glass level gauges are relatively inexpensive as compared to most other level technologies.

Please provide the following parameters when ordering:

1. Model specification;
2. The name of the medium to be measured, such as: water, petrol, paraffin, etc..
3. Material requirements: e.g. SS304, 316L, carbon steel;
4. Connection: flange or thread;
5. Flange standard: nominal diameter of the flange, currently used more DN20 or DN25 flange;
6. Measuring range of the instrument: the centre distance of two flanges;
7. Material of glass tube, diameter, length, wall thickness;
8. Working pressure: the highest withstand pressure;
9. Working temperature: minimum and maximum temperature of the measuring liquid;
10. Special requirements: please explain in detail before ordering, such as whether to take the remote transmission, thermal insulation jacket and so on.
