Method and device for measuring a flow rate of powdered or granular solid materials transported continuously

摘要

The subject of the invention is a method and device for measuring a flow rate of powdered or granular solid materials transported continuously. In order to reduce the investment and maintenance costs, a screw conveyor (14) is used to transport the materials over at least part of the path which is imposed on them, the power taken up by the drive motor (18) of the screw is measured and the flow rate of the solid materials transported is determined using a calibration curve. <IMAGE>
