Product Description

Liquid Tank Level Indicator Boiler Sight Glass Level Gauge

Product Description

Glass plate level gauge is divided into three kinds: Transparent type, reflection type and sight glass type. The level gauge is mainly composed by level gauge’s body, upper valve (gas valve), lower valve (liquid valve), drain valve, insurance steel ball and so on. When the glass plate have some cracks or be damaged, the insurance steel ball will automatically stop the side valve of gas and liquid to avoid or reduce flowing. So the worker can cut off the bottom valve to handle it. This series product is stable, sealed and reliable, simple installation, which is ideal instrument for detecting for liquid level in all kinds of containers with middle or low pressure.Connecting the upper and lower flanges of this level gauge with the upper and lower flanges of the container to form a permeator, then the height of liquid can be directly seen.

The glass plate type liquid level meter is designed based on the principle of the communicator. The liquid passage formed by the glass plate and the liquid level gauge body is connected to the measured container through a flange or a taper pipe thread to form a communicator, which is observed through the glass plate. The liquid level is the same as the liquid level in the container, that is, the liquid level.

The needle valve at both ends of the level gauge not only functions as a stop valve, but also has the function of a check valve in the internal steel ball. When the liquid level gauge accidentally breaks and leaks, the steel ball can automatically close the liquid passage under the action of the medium pressure. To prevent the large outflow of liquid for safety protection. The level gauge can change the material of the part or add some ancillary parts to achieve anti-corrosion, thermal insulation, anti-frost, lighting and other functions. Widely used in petroleum, chemical industry, electric power, metallurgy, medicine and other fields.

Tips for installation

1. During installation, in order to ensure the function of automatic sealing, the liquid in the container must have a certain pressure, at least more than 0.2MPa. When the upper and lower valves are opened, the valve stem quitting cannot be less than four turns. When the steel ball seals the door, it does not hit the top of the valve stem to avoid damage.

2. In the process of transportation and unpacking, we must be careful not to encounter something harder to avoid breaking the glass plate.

3. Also pay attention to the specifications and models, cannot install the wrong gauge level gauge, some media on the leveler is limited, such as some of the glass or steel plate corrosive media cannot be used.

4. Other maintenance clean, wash and install with the glass tube level gauge is similar


Instructions for use of two-color quartz tube level gauge:
●When using the water level gauge, first slowly open the valve to enter the liquid, and then the special glass tube is preheated for 20-30 minutes. After a certain temperature, the valves at both ends can be opened to enter the water or other media.
● Frequent draining is required during use to avoid clogging of channels and false water levels.
●When the quartz tube is accidentally damaged, turn the plug of the upper and lower cock 90 by the upper and lower handles of the instrument to prevent the medium in the container from flowing out. At this time, the damaged parts can be replaced.
●The packaged water level gauge can be transported by conventional means of transportation, but severe vibration and direct erosion by rain and snow should be avoided.
●The water level gauge should be placed in a dry and ventilated room with a temperature of 0-40°C and a relative humidity of no more than 80%. The outdoor air should not contain any corrosive media.
●The water level gauge must be installed vertically, and its vertical deviation should be less than 3.
● There should be a shut-off valve between the water level gauge and the container to isolate it from the medium during cleaning and maintenance.
