Quartz tube level gauge
产品介绍
The quartz tube liquid level gauge is a direct reading instrument that monitors the liquid level of industrial boilers, heaters and other pressure vessels and liquid storage tanks as a visual window. The device combines optical and mechanical technology, allowing the monitor to visually observe the liquid level. It has the characteristics of simple structure, convenient installation and maintenance, clear display, corrosion resistance, etc. It is mainly suitable for liquid level monitoring of liquid storage tanks and other devices in petrochemical, metallurgy, electric power, food and other industries.
  
Working principle
Quartz tube liquid level gauge is divided into two kinds of indication forms: single color and double color. Quartz tube double color liquid level gauge is based on the principle of light transmission and reflection, through the optical principle, the gas phase is red, and the liquid phase is green to display the liquid level. Because of the large contrast between red and green, the liquid level indication is clear and obvious, full liquid is green, no liquid is full red, it is easy to determine whether there is liquid or no liquid, avoid accidents of full liquid and no liquid, and ensure the reliability of the monitored device.

 

Technical advantages
Quartz tube two-color liquid level gauge is a product developed by our company in the 1980s. The product has won the national patent and passed the provincial technical appraisal in 1990. After nearly 40 years of improvement in technology and process, the quartz tube two-color liquid level gauge has the advantages of safe and reliable operation, clear display and easy observation, and has formed a standardized and serialized product.
  
Quartz tube two-color liquid level gauge is divided into two structures with blind area and no blind area. The structure without blind area is the same as the center distance and the visual range, which has a larger observation range and is easy to observe. The quartz tube two-color liquid level gauge uses a quartz tube with a silica content of more than 99.99% as the liquid level measurement body. Compared with the ordinary glass tube liquid level gauge, it has high temperature resistance, low temperature resistance, high pressure resistance, and the liquid level is clear and obvious. advantage.
  
The quartz tube two-color liquid level gauge breaks through the previous structure display form, adopts the LED light source structure to display the liquid level, and changes the position of the red and green filter plates from the same side of the liquid level gauge to three directions of the liquid level gauge. A power supply adjustment device that can adjust the brightness of the light source is added, so that the red and green display of the liquid level gauge can achieve a very clear effect, making it easier to observe the liquid level.
  
For the measurement of high viscosity and low boiling point liquids, a jacket device is added to the level gauge. High viscosity liquid is easy to solidify, steam or high temperature liquid is introduced into the jacket to make the temperature in the liquid level gauge consistent with the temperature in the measured device to ensure the accuracy of liquid level measurement; low boiling point liquid is easy to boil, resulting in inaccurate measurement The liquid level is fixed in the jacket and cooling water is introduced to stabilize the liquid level to obtain an accurate liquid level. Quartz tube two-color liquid level gauge is equipped with automatic protection function of safety ball on the steam and liquid valves. Once the quartz tube leaks, the safety ball can immediately cut off the vapor-liquid passage under the pressure of more than 0.2MPa to prevent liquid leakage. , to avoid the occurrence of safety accidents.
