The bulk material, the amount o which is to be determined through second-integration or time-integration, passes over a top chute onto a bottom chute which is disposed at a tilt angle and defines the velocity of the bulk material. The bottom chute channels the bulk material to a slide which has the same angle of tilt as the bottom chute. The weight components of the amounts of bulk material on the slide acting orthogonally along the direction of the slide are determined by a load- sensing device. After passing down the slide the bulk material impacts a vertically arranged deflector plate which is rigidly connected to a connecting plate, with the deflector plate at that point generating a force through its change in its pulse action which is determined by a second load-sensing device. The second load-sensing device only measures the horizontal components of this change in pulse action, and, like the initial load-sensing device, is either parallel channelled or provided with parallel channelling. Both load-sensing devices are connected via lines to a computer which contains the evaluation formula and all relevant correction parameters stored in its memory. Both of the chutes and the load-sensing devices are supported by a frame. Once having been weighed, the bulk material falls into a funnel.
