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.
Product Features:
▲The reading is clear, intuitive and reliable.
▲ simple structure, easy maintenance.
▲Durable, it is an ideal instrument for observation of the liquid level in various medium and low pressure vessels.

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.
