An explosion-proof radar level gauge is a liquid level measurement instrument used in flammable and explosive environments.

Similar to a regular radar level gauge, the explosion-proof radar level gauge measures liquid level by emitting and receiving radar waves and utilizing the reflection principle of radar waves on the medium surface. The emitted electromagnetic waves are reflected by the medium surface and then received. By calculating the time difference, phase difference, and other parameters between the emitted and received signals, the distance between the radar installation position and the material surface is obtained, and thus the liquid level height is determined.

• Reliable explosion-proof performance: Complies with relevant explosion-proof standards such as ATEX, IECEx, CNEx, etc. The explosion-proof grade is usually Ex ia IIC T6 (intrinsically safe type), Ex d IIC T6 (explosion-proof type), etc. For example, the RAE GUL15 intrinsically safe explosion-proof radar level gauge complies with the Ex ib I Mb explosion-proof grade and is suitable for explosive environments containing methane and coal dust, such as underground coal mines.
• High measurement accuracy: Utilizes high-frequency radar technology, such as 80GHz, 120GHz, etc. high-frequency electromagnetic waves, with a small beam angle and strong focusing ability. The measurement accuracy can reach ±1mm to ±3mm.
• Strong anti-interference ability: High-frequency signals have stronger anti-interference performance in complex industrial electromagnetic environments. Some products also have advanced signal processing technology that can automatically suppress false echoes and effectively resist interference caused by surrounding obstacles, agitators, foam, steam, dust, etc.
• Wide application range: Can be used to measure the liquid level of various liquids, slurries or solid particles. Suitable for flammable and explosive hazardous areas in industries such as petroleum, chemical, pharmaceutical, food, energy, metallurgy, and environmental protection, such as crude oil storage tanks, liquefied gas storage tanks, reactors, alcohol storage tanks, coal powder silos, etc.

Installation: During installation, avoid interference sources such as feed inlets and agitators to ensure that the radar wave propagation path is unobstructed. The antenna should be vertically aligned with the liquid surface. For special installation requirements, such as inclined installation, angle compensation can be achieved through software adjustments.

Maintenance: Regularly clean the antenna surface to prevent scaling, dust accumulation, and other factors that may affect signal transmission and reception. Additionally, verify and calibrate the data every 6 months to 1 year based on actual usage to ensure measurement stability and accuracy.
