The UGS (UNS) series color quartz tube level gauge (hereinafter referred to as the color level gauge) is developed using the latest technology at home and abroad. It utilizes the principle of natural light refraction and reflection in liquids, with the help of red and green plates, to make the liquid phase display green and the gas phase display red during measurement. Due to the large contrast and clear indication of liquid and gas phases, it is more advantageous for remote operation and night patrols. Therefore, it is widely used in various transparent liquid containers and boilers in industries such as petroleum, chemical, power, metallurgy, etc., for liquid level measurement of oil products and chemical raw materials such as water, gasoline, liquefied gas, liquid ammonia, propane, propylene, aromatic hydrocarbons, acids, etc. For interface measurements of two different medium densities, a three color interface quartz tube level gauge can be used. The three color interface quartz tube liquid level gauge is designed based on the principle of buoyancy and specific gravity difference. The small float in the quartz tube is suspended at the boundary between the two media. Due to the black color of the float, the liquid color in the upper and lower parts is different, making the display eye-catching. Thus solving the problem of unclear interface between two mixed media that has been troubling in the petrochemical production process. It is currently the most ideal direct reading liquid level gauge both domestically and internationally.

UGS (UNS) series color quartz tube level gauge features:

Direct reading, accurate reading, reliable
Simple structure and easy maintenance
Safe and durable to use
Instructions for Use:
To ensure self sealing, the pressure of the medium inside the container should be greater than 0.2 MPa. When opening the upper and lower valves, the number of rotations of the valve stem should not be less than 4 to prevent the steel ball from touching the top of the valve stem during self sealing. Structure and characteristics:
The UGS (UNS) series color quartz tube level gauge utilizes the principle of natural light refraction and reflection in liquids.
By using red and green chips, the liquid phase is displayed in green and the gas phase is displayed in red during measurement. Due to the liquid gas phase
The display has a large contrast and clear instructions, making it more advantageous for remote operation and night patrols.

Clear liquid and gas phase display, no blind spots, good sealing performance, high temperature and high pressure resistance, anti viscosity, light weight
Ordered to be long and leak free.
Simple structure, easy installation and maintenance, corrosion-resistant, no need for power supply, explosion-proof.
