With the vigorous development of the cement industry and the continuous improvement of the automation level, it is more and more urgent to continuously monitor the level of powder silo. All kinds of powder silos in a cement plant are important parts of the production process.
However, how to accurately and reliably measure the level of powder silo has always been a difficult problem faced by cement plants. The most important reason is that a large amount of dust will be produced when the silo is discharged and the level of dust is very fluffy. The instrument is often in the state of loss of wave, but the instrument can still increase the level value according to the input rate, thus causing errors. Is there a better way to measure the bin position?
The customer has used the cable level gauge, indicating that it is not allowed. Ultrasound level indicator is also inaccurate, and the ultrasonic transmitting antenna is often pasted by limestone powder, resulting in the inaccurate level indicator. It is equipped with instrument air blowback, but the effect is not obvious, but it increases the maintenance cost.
If you want to save costs with guided wave radar level meter HBRD703 can, such as budget adequately with high-frequency radar level meter HBRD904 will be better, both types of radar have been used in the presence of limestone powder, cement powder, pulverized coal occasions.
After compare, the customer chooses HBRD904. It uses a non-contact measurement with the medium, generally used in solid materials, process containers or strong dust easy to crystallize, dew occasions. It is the best choice for measuring solid powder and low dielectric constant dielectric because its emission angle is only 4 degrees and energy is concentrated, which enhances the echo ability and avoids interference.
