ULG Series Glass Tube Liquid Level Gauges
Summery
The ULG series of glass tube level gauges are in-place level measuring instruments that can be used for level measurement in a variety of containers. According to the principle of the connector, the liquid level in the container is introduced into the liquid level gauge tube, and the liquid level height is directly read on the front surface of the gauge. Using the principle of light refraction, the liquid portion of the gauge is green and the air portion is red. This kind of gauges has been widely used in petroleum refining, chemical, electric power, metallurgy, pharmaceutical, light industry and other industries.
Structure
The shell of the ULG series glass tube level gauge adopts a special solid structure. The quartz glass tube with high strength is used as the main component. The special level gauge valve for easily cleaning is used. The special valve of the level gauge is equipped with a steel ball, when the glass tube is accidentally broken, the steel ball closes the medium passage under the pressure inside the container to prevent the liquid in the container from leaking.
Features
Level gauge can be cleaned online
360°free rotation in visible direction
Safe and reliable with special valves for liquid level gauge
Gas-liquid two-color display, intuitive observation
