What type of level gauge is suitable for coal powder silos?

What are the requirements on site? If using radar, is guided-wave radar or horn-shaped radar better? Which brand offers reliable measurements? Are domestic ones okay?
The performance of the director’s radar is likely to be slightly better than that of the funnel-shaped radar; the funnel-shaped radar is vulnerable to reflected radar waves caused by suspended particles inside the powder container, while the director’s radar is mainly concerned about the director’s rod sticking to the walls.
Use Kelon’s spherical radar! These problems can be solved! It works great! You can give it a try!
I recommend gamma-ray level gauges, as they provide accurate measurements.
It’s best not to use those flared types; our company is using them currently, and accuracy is compromised whenever there are suspended particles. We’re considering switching to other types
Reply to 1# Visitor: Radar or nuclear radiation, either works. Nuclear radiation measurement is more accurate, but it requires many approval procedures.
Reply to 1# Visitor: The original poster can use a level gauge with an air-blown nozzle; when the instrument is in use, a certain flow rate of nitrogen should be used to purge the probe, thereby preventing coal ash from sticking to it – this approach works well
Reply to 3# jun7203: The strength of the flexible cable is a concern for using guided wave radar
Reply to 5# Aixue*2011: It’s too troublesome
The Emerson 5600 series parabolic radar level gauges are used, and Shenzhen Wanxun’s high-frequency pulse radars also perform well in coal silos and cement silos.
Reply to 9# Visitor: This means that it’s necessary to add more weight beneath the cable. Generally, the level of material in the powder bin isn’t uniform, especially during the discharge process; therefore, it’s important to choose the right installation location.
