The USGS series dual color quartz glass tube level gauge is the most common and commonly used type of quartz glass tube level gauge. When measuring, it displays the liquid phase in green and the gas phase in red. Due to the large contrast between the liquid and gas phases, the indication is vivid, clear, and intuitive, and can be observed from a distance. The viewing direction and center distance can be adjusted. This series of products is widely used in industrial fields such as petroleum, chemical, power, metallurgy, military, and food.

The USG S series dual color quartz glass tube level gauge mainly consists of a quartz glass tube, a color filter red and green glass sheet, a body, upper and lower valves, and a drain valve. The upper and lower valves are eccentric right angle needle valves, which are easy to clean. The flange of the liquid level gauge is connected to the flange on the container to form a connector. Using the principle of the connector and the optical principle of natural light breaking and reflecting in the liquid, the gas phase appears red and the liquid phase appears green with the help of red and green glass sheets. The red and green displays are clear and can be observed from a distance and inspected at night.

The USGS dual color quartz glass tube level gauge is used to measure the liquid level of colorless transparent liquids or lighter colored liquids.

The U G S J type jacketed dual color quartz glass tube level gauge is used to measure the liquid level of colorless transparent liquids or lighter colored, viscous, and easily condensable media.
