Working principle and structure
The glass tube level gauge is based on the principle of connectedness and a liquid passage made of glass tube. The connection between the flanges or the taper pipe threads is connected with the tested containers, and the liquid level observed through the glass tube is the same as the liquid level in the container, that is, the height of the liquid level.
The tube level gauge is mainly composed of glass tube, protective sleeve, upper and lower valves and connecting flange (or thread). The liquid level gauge can change the material of the part or add some accessory parts to achieve the function of anticorrosion or thermal insulation.
Application scope and characteristics
This product is made of quartz glass tube with excellent properties, such as high temperature resistance and high pressure. Besides, the utility model has the advantages of simple structure, economy and practicality, convenient installation, reliable operation and long service life.
As the basic level indicator liquid level gauge, this product is widely used in liquid level measurement and monitoring in large scale engineering projects with simple liquid level measurement and low automation degree.
