Measuring the mass flow of wood chips or bark

The main advantage compared to conventional weighing systems is that the radiometric belt weigher does not need to be recalibrated and provides reliable results during many years of operation. The system can be installed on belt conveyors, drag chain conveyors, screw conveyors, hence on all known conveyor types. Installations on existing boiler feeding lines are easily feasible.
