Some dust, Ore varies in lump size, repose angles vary.
Level Technology Choice:
Since we are measuring large ore lump material, as well as other materials, like wood etc. that have been removed from the process, a non-intrusive level technology is recommended. Both Radar and Acoustic will work fine in this application. Because the repose angle can vary greatly within the bin, a 15 kHz acoustic transmitter is recommended. Positioning of the transducer, should be one third in from the outer wall, aimed at the draw point of the vessel.
The 15 kHz transmitter can also be supplied in 2 wire configurations as well as Foundation FieldBus, ProfiBus PA.
