Structural principle:
The upper and lower ends of the instrument are equipped with flanges connected to the flanges of the boiler or container, and the actual height of the liquid vapor inside the container can be directly observed through a water level gauge

Instructions for Use:
When using the water level gauge, it should be preheated for 20-30 minutes first. After the glass plate has reached a certain temperature, the valves at both ends can be opened to allow water or other media to enter.
During use, it is required to regularly discharge pollutants to avoid blockage of channels due to erosion and false water levels.
