ABSTRACT OF THE DISCLOSURE FLOW METERING DEVICE In a combine harvester having a clean grain conveyor, a clean grain weight rate metering device is provided generally at the discharge end of said conveyor. The weight rate metering device incluedes a sensor member disposed to be acted upon by the clean grain flow as it issues from the clean grain conveyor, and a transducer operatively associated with the sensor member to continuously generate a signal proportional to the clean grain weight rate. The sensor member is curved in shape and is operatively disposed generally in the path of the clean grain flow issuing from the conveyor for deflecting the direction of movement of the clean grain flow and for guiding said flow therealong while subjecting the sensor member to a centrifugal force. The inventive concept also may be used in a flow metering device for metering the weight rate of any type of materials flow and generally always comprises conditioning means forwardly of the sensor member for concentrating, in a coherent stream, all the material of the materials flow and for transferring said coherent stream to the sensor member for guiding said coherent stream in permanent contact with the sensor surface as it is moved through the sensor member.
