ABSTRACT:
The gravimetric control of a mass flow from or into a container located on a balance using a pulsating dosing pump, the output signal of the balance is digitally filtered in such a manner that the course in time of the mass flow is cyclically estimated from the filtered wighing signal. This estimated value of the course in time of the mass flow is used to calculate the course in time of an auxiliary mass flow which compensates the pulsation of the mass flow of the pulsating dosing pump and a speed course is calculated from the course in time of the auxiliary mass flow for driving an auxiliary dosing pump.
