In a coal-fired power plant, the coal is transported from the yard to the silos on a conveyor system.
The process of dumping coal from the conveyed buckets into the silo creates a lot of dust.

A couple years ago, Siemens published a great handbook on using radar to measure solids levels, but the $60 price tag limited its readership.
You can now download the book for free as an electronic epub file formatted for electronic readers, which in my case, is the Firefox browser on my laptop. It could be any browser (Internet Explorer or Chrome), or presumably any electronic book reader.
In order to understand level readings, you must first comprehend how the instrument works. Three of the most common level-measuring techniques involve using a displacer, float, or differential pressure instrument.
Here’s the catch.
While each of these instruments can be used to report a level reading, none of them actually measure level.
I know what you’re thinking…
If none of these instruments measure level, how do we end up with a level reading? Read the rest of this entry »
Recently, we’ve run into a few radar level applications that had some startup challenges, mostly because the person installing the transmitter didn’t consider how radar wave transmission would affect the level transmitter’s performance.
One trick to any installation is to reduce the number of obstructions encountered by the transmitter. But you have to take into consideration that radar waves don’t transmit in a concentric circle around the transmitter. And this can create a problem of its own.
