The principle and characteristics of quartz tube level gauge


Quartz tube liquid level gauge is a commonly used human instrument, widely used in various transparent liquid containers and boilers in industries such as petroleum, chemical, power, metallurgy, etc., such as water, gasoline, liquefied gas, liquid ammonia, propane, propylene, aromatics, acids, and other oil products and chemical raw materials for liquid level measurement. The editor will mainly introduce the principle and characteristics of quartz tube level gauges, hoping to be helpful to everyone.

Principle of Pipe Level Gauge

The UGS (UNS) series color quartz tube level gauge utilizes the principle of natural light refraction and reflection in liquids.

With the help of red and green chips, the liquid phase is displayed in green and the gas phase is displayed in red during measurement. Due to the large contrast in liquid and gas phase display and clear and distinct indications, it is more advantageous for long-distance and night patrols.

Characteristics of quartz tube level gauge

Clear liquid and gas phase display, no blind spots, good sealing performance, high temperature and high pressure resistance, anti viscosity, light weight, and no leakage.

Simple structure, easy installation and maintenance, corrosion resistance, no need for power supply, explosion-proof.

Main technical specifications of UGS series color quartz tube liquid level gauge

A specially made 99.99% SiO2 transparent quartz tube with a deformation point of 1077 ℃ and a softening point of 1730 ℃.

The compressive strength is 1170Kg/cm3, and the number of expansion systems is 5.5 × 10-7。 After special processing, it has high temperature resistance, high pressure, and excellent mechanical properties.

Measurement range L: The measurement range is determined by the mid range: 300, 500, 800, 1100, 1400, 1700, 2000mm. Please indicate the dimensions for special specifications.

Heat tracing steam jacket: working pressure 0.6MPa, nozzle size G1/2 ″ external thread.

Interface flange: The HG20592-20635-97 flange standard newly issued by the Ministry of Chemical Industry in 1997 is adopted. The flange diameters are DN20 and DN25. If users need to use other standards (such as GB, ANSI, etc.), they can be designed according to their needs. Automatic sealing pressure of steel ball: greater than 0.2MPa, weighing 15-30kg.

What are the advantages and characteristics of quartz glass

For laymen, the types of glass may be limited, as most glass is "the same" in appearance. But for glass professionals, there are so many types of glass that I am not sure if I can list them completely.


The Formation and Application of Quartz Tubes

The formation of quartz glass is due to the high temperature and viscosity of its melt. It is widely used in the production of semiconductors, electro-optic sources, semiconducting communication devices, lasers, optical instrument, laboratory instruments, electrical equipment, medical equipment, high-temperature and corrosion resistant chemical instruments, chemical industry, electronics, metallurgy, building materials, national defense and other industries.
