High Temperature 1750mm Boiler Level Gauge Glass For Tank Level
Working principle:
The glass plate type liquid level gauge is designed based on the principle of the connecting device. The liquid path composed of the glass plate and the main body of the liquid level gauge is connected to the container to be measured through the flange or taper pipe thread of the connecting pipe to form the communicating device. The liquid level is the same as the liquid level in the container, ie the liquid level height.
The needle valves at both ends of the liquid level gauge not only function as a shut-off valve, but the internal steel ball has the function of a check valve. When the liquid level gauge accidentally breaks and leaks, the steel ball can automatically close the liquid channel under the action of the medium pressure. Prevent large amounts of liquid from flowing out and play a role in safety protection. The liquid level gauge can achieve the functions of anti-corrosion, thermal insulation, anti-frost, and lighting by changing the material of the parts or adding some auxiliary components. Widely used in petroleum, chemical industry, electric power, gold, medicine and other fields
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.

Production Workshop
Certificate
| 1. | 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. |
| 2. | Frequent draining is required during use to avoid clogging of channels and false water levels. |
| 3. | 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. |
| 4 | 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. |
| 5. | 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. |
| 6. | The water level gauge must be installed vertically, and its vertical deviation should be less than 3. |
| 7. | 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. |
