44 Throughput measurement with the QUANTIMETER. By recording the deflection of the upper rear precompression roller, together with the intake width and intake speed parameters, the volume flow is measured continuously. Counterweighing is recommended in order to ensure the highest possible degree of accuracy (tonnes per hectare). Retrospective adjustment of the yield data obtained at the start of the job is possible. Retrospective calibration using a new calibration value allows counterweighing to be delayed until any point between the start and finish of the harvesting process.
