This level indicator is designed to be able to adapt to high temperature, high pressure environment level measurement work, so the liquid level meter body, gland, Cock is made of 20 # mild steel,and the width of the body and the width of the gland is the same, to ensure that the high temperature, high pressure environment this level meter can be used in the production of long-term use of temperature up to 450 ° C. The glass plate is made of borosilicate material, which has the characteristics of high temperature and high pressure resistance. The long-term use temperature is 450 ℃, and the bending strength reaches 300Mpa, The gaskets used are of high quality, uniform thickness, and precise die-cutting. The standard gasket material is compressed non-asbestos, but other materials that are most suitable for the application can also be provided. This liquid level gauge is suitable for long-term liquid level measurement in most high-temperature and high-pressure environments.

High-pressure glass plate level gauge also has a self-closing (self-locking) function, the level indicator on the cock has a self-locking steel ball, when the level indicator on the glass plate because of accidental breakage, the pressure inside the container and the level indicator in the pressure difference of 0.2Mpa, the steel ball in the pressure difference under the action of the blocking of the inlet and outlet, the container will not be from the level indicator  of the medium of the observational surface of the occurrence of a large number of leaks, so as to avoid the user’s This can avoid the economic loss of the user and the occurrence of staff injury.

Product Features

• Simple installation and maintenance.
• Does not require electricity to operate. Still works in the event of a power outage.
• Directly observe the liquid level position-no calibration is necessary.
• Capable of long-term stable level measurement in high temperature and high pressure environments.
• Reasonable sealing structure, no leakage; Low maintenance costs;

There are two types of High-pressure glass plate level gauge: High-pressure transparent glass level gauge and High-pressure reflex glass level gauge.

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 measured medium, such as: water, gasoline, kerosene and so on. Medium density, if you do not know the density, you can tell us the name of the medium, mixed liquids to know which liquids are composed of;
3. Measuring range of the instrument: the center distance of the two flanges;
4. Operating pressure: the highest withstand pressure;
5. Operating temperature: the minimum and maximum temperature of the measuring liquid;
6. Material requirements: such as: SS304, 316L, carbon steel, if you do not know which material, you can ask us (we will choose different materials according to different media);
7. Whether supporting the supply of flanges, bolts, nuts, valves, sealing washers and other accessories;
8. Flange standard: the nominal diameter of the flange, the more widely used flange is DN20 or DN25;
9. Special requirements: please specify in detail before ordering, such as whether to take the remote transmission, thermal insulation jacket and so on.
