Analysis Of The Problem Of Continuous Measurement Of Powder Level in The Petrochemical And Coal Industries

Compared with other fields, there are a lot of powder in the petrochemical and coal industries, and the continuous measurement and control of the powder level is crucial to the subsequent process. In order to choose the right radar level meter model, it is important to understand the challenges of radar type continuous level meter in powder measurement.

Containers for storing liquids are usually tanks or tanks, while containers for storing powder are mostly silos. Silos are generally slender and narrow. Whether it is a radar type continuous level meter or an ultrasonic level meter, in such a narrow space, the silo wall may generate interference signals, affecting the actual echo signal. Therefore, these interference factors must be taken into account when continuous measurement of powder material level.

Interference signals may affect the radar level meter, and the dust in the silo will also cause the radar wave signal to attenuate, and in severe cases, the echo signal may not even be received. In this case, when choosing a radar type continuous level meter, you should consult the salesperson to ensure that you choose the right radar level meter model.

Powders are usually measured using non-contact radar level meters, but this measurement method may cause powder to adhere to the antenna surface. Especially when dry materials generate static electricity, the powder will adhere to the antenna faster. To solve this problem, some companies use protective covers, while others add purge devices.

Although the problem of powder adhesion on the antenna can be dealt with, powder with low dielectric constant is difficult to solve. Low dielectric constant will cause the echo signal of the radar type continuous level meter to be unstable, or even unable to measure. Therefore, when measuring powder, you need to first understand the dielectric constant of the powder and consult sales staff for professional advice.
