Measuring the mass flow of recycled paper

This system has no moving parts and measures the bulk flow contact-free and non-intrusive. Installations are possible on all conveyor types, e.g. belt conveyors, drag chain conveyors, bucket conveyors or screw conveyors. The measurement is highly accurate and repeatable, so that there is no need for recalibrations.
