The dosing units of the type BUCsmartflow are used in situations, where bulks (powder or granular products) with poor flow characteristics have to be dosed down to a gramm and high requirements on the cleaning process have to be fulfilled. Those can be installed directly at the bottom of a silo or somewhere in the bulk down-stream. Typically, those are used in combination with the intelligent Dosing Controller BUDos and the flexible connection system BUClamp Compensator.
