<p>A grain handling system comprises a valve device for controlling a flow rate discharged from a downstream end of at least one flow passage. A volumetric weight measuring device measures the weight per unit volume of the grain delivered toward the valve device to generate a volumetric weight signal. A computer generates a control signal on the basis of the volumetric weight signal. A drive device drivingly connected to the valve device is operative in response to the control signal to drive the valve device so as to allow the grain discharged from the valve device to be controlled in terms of weight unit.</p> |
