An arrangement for conveying product material to a weighing system includes an infeed for product material to be weighed and at least one dosing mechanism for controlled conveying of product material portions from the infeed to a weighing system. The dosing mechanism includes a motor-driven transport screw formed as a helically-shaped rod positioned in an open trough for conveying the product material from the infeed to the weighing system, and a control unit for controlling the motor in order to deliver a desired portion of product material to the weighing system. This arrangement provides a gentle, well-defined conveyance of product materials that are not suited for vibrational conveyance or conveyance by a screw conveyor in a tubular housing.
