Abstract

A method for determining a mass flow composed of bulk material, in particular grain, which is conveyed by means of a continuous, circulating conveyor, having planar conveyor elements, from a lower bulk material receiving area to a higher bulk material delivery area, in which the bulk material delivered by the conveyor is deflected by a guide surface disposed in the bulk material delivery area toward a measuring device, wherein the mass flow is determined by the measurement of a resulting force (F_G) exerted on a sensor surface of the measuring device, wherein at least two parameters having an effect on the force measurement, in particular parameters independent of bulk material properties, are compensated for. A control and regulating device for executing the method for determining a mass flow composed of bulk material is also provided.
