Does the radar level gauge used to measure the coal tower require purging? If purging is required, are there any purging methods that do not require disassembly?
If you use a guided-wave radar, there’s no need for purging. . . If there’s a lot of dust in the coal bin, it’s definitely a good idea to clean it out!
Radar units can be equipped with a purge device; as for whether to connect air or not, it’s up to you to decide!
The coal dust issue of yours is probably not as severe as that in the cement silo; a protective cover should suffice. Still, it needs to be cleaned regularly. Radar systems, on the other hand, require a lot of maintenance and present many problems
It needs to be purged regularly; the radar in our unit keeps having problems – even a little dirt is not acceptable
Ordinary instruments require instrument air, but with the advancement of technology, the old radars are about to be phased out. A three-dimensional level gauge has been developed; it uses static electricity to remove dust and requires virtually no maintenance. But the price is relatively high.
Radar units can be equipped with a purging device; just inform the manufacturer to add it when placing the order
No matter how well something is described, practical use is what matters most. No one can guarantee accuracy and reliability; what’s important is stable performance over time. Can you ensure that there is barely any need for maintenance twice a year?
The purge function and the dust cover cannot be used simultaneously. Usually, the dust cover is sufficient to solve the problem, but if there are deviations in the measurement results after some time of use, it is necessary to clean the dust cover.
