Transparent glass level gauge is also known as transparent liquid level indicator, transparent liquid level meter. Transparent liquid level gauge is equipped with two transparent glass panels, between which there is liquid. When the upper chamber is filled with gas and the lower chamber with liquid, the level is indicated by the different transparency of the two media. At the back of the transparent glass level gauge is a light source with rays reflecting down to the observer making it possible to read or estimate the measurement.

Transparent glass level gauges are suitable for most applications. Compared to reflex glass level gauges, transparent glass level gauges can be used at higher working pressures and in certain corrosive fluid environments.

To avoid leakage in the event of glass breakage, a safety ball check device is usually fitted to the cross-connector or shut-off valve. To protect the glass surface from the corrosive effects of process fluids, transparent glass level gauges can be fitted with mica shields or PTFE shields.

Product Features

Simple installationand 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.

It has a quick shut-off device for vapor and liquid leakage;

Low maintenance costs;

Suitable for vapor media up to 100 bar and process media up to 400 bar

One-section transparent level gauge                                                     Multiple-section transparent level gauge

Why use flat glass gauge 

Transparent 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.  Transparent 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.
