Abstract
The aim of the invention is to reduce the complexity of installing and placing into operation a device for effecting continuous gravimetric dosing and determining the mass flow rate of free-flowing products with a dosing device (4) and with the determination of the instantaneous mass flow rate before a delivery location (8) by means of a dosing controller (10), whereby the discharge is controlled by varying the rotational speed of a drive (6) of the dosing device (4) by means of a motor controller. The aim of the invention is achieved by virtue of the fact that the dosing device (10) and the motor controller (20) are combined to form a subassembly (G).
