UGS/UNS series two-color quartz tube level gauge is a liquid level product that uses optical principles and high-quality quartz tube materials. It is an updated product of ordinary glass tube level gauges and is widely used in petroleum, chemical, electric power, metallurgy, etc. The level measurement of various transparent liquid containers and boilers in the industry, such as: water, gasoline, liquefied gas, liquid ammonia, propane, propylene, aromatic hydrocarbons, acids and other oils and chemical raw materials. It is also suitable for the boundary of two different medium densities. Position measurement. The two-color liquid level gauge is installed on various measuring containers, and the liquid level changes can be directly observed. The liquid phase display is green, the gas phase display is red, and the interface measurement is a three-color interface. The contrast between liquid and gas display is very clear, and it is clear and clear in long-distance observation and night patrol. It successfully overcomes the shortcomings of ordinary plate level gauges such as bulkiness, large sealing area, easy leakage, unclear display and difficult color observation at close range. There are standard type, heat preservation type (stainless steel sheath with heat preservation pipe), anti-corrosion type (teflon sprayed in the wetted part), full range type without blind zone, and also can choose to install lighting equipment at night or Use in poorly lit places.
In the display of the level gauge, it makes full use of the principle of light reflection and refraction, and uses a special structure and process to design and manufacture. The level gauge displays the liquid phase is green, the gas phase is red, and the level display is more intuitive and clear, far better than ordinary Glass tube level gauge, which can directly read the actual liquid level height of the liquid level in the container.

① High temperature and high pressure resistance:
The raw material of this product's quartz tube is made of transparent quartz tube with a purity of up to 99.99% silica. It is treated with a special process and has strong high temperature resistance, high pressure resistance and excellent mechanical properties. Its deformation point temperature is as high as 1077 ℃, and the softening point temperature is 1730. ℃, compressive strength 10MPa. Expansion coefficient 5.5X10-7. Compared with the glass tube, the glass tube has stronger corrosion resistance and pressure resistance, and has the characteristics of uniform thickness, high transparency, clear indication, corrosion resistance, high temperature resistance, and high pressure resistance.
②Two-color color display liquid level or interface level:
The quartz tube of this product adopts a special structure. At the same time, the level gauge shield is processed by a special process, making full use of the principle of natural light refraction and reflection in the air and liquid, so that the gas phase is displayed in red, the liquid phase is displayed in green, and the red and green phases are Measure the liquid level to make the liquid level display more intuitive and clear.
③Self-sealing design:
The cork (valve) part of this product adopts a safe self-sealing structure design. When the glass tube is broken due to external force, it can effectively prevent the continuous flow of the medium in the measuring container and the tank from causing accidents or economic losses. The self-sealing structure It provides a very effective safety guarantee for the safety measurement of the glass tube.
④Low temperature can be equipped with temperature heating or cooling device:
The heat tracing or cooling device can be customized according to the customer's measurement requirements. The connection port has various forms and can be customized according to the customer's on-site interface form or size. It is easy to install and does not require the customer to change the interface form or size. When heating, it can be heated by steam or hot water to prevent freezing or crystallization of the medium due to low temperature. During cooling: When the temperature of the measuring medium is too high and vaporization is easy to occur, cold water can be used for cooling to slow down the vaporization of the medium and make the liquid level display more accurate and stable.
⑤ Display scale ruler:
The panel display scale material of this product is made of high-quality aluminum alloy. The panel display scale is clear and accurate, and it can be used for a long time and is not easy to fade.
⑥Lighting device:
In order to improve the visibility of this product, this product can add a lighting device in the passport, which can be conveniently used in a dark environment, the display value is clear, accurate, and the reading is convenient.
⑦ No blind zone design:
In order to meet the customer's requirements for no blind zone measurement, this product can be designed with a special process structure to achieve the product's no blind zone measurement requirements.
