ABSTRACT:
A plurality of vessel receptacles and load cells are mounted along the outer periphery of a revolving body at an equal circumferential spacing. A filling device is disposed above each of the vessel receptacles. In a first operational mode for filling the receptacles, the tare of each vessel which is supplied onto one of the vessel receptacles is measured and such data is fed to a controller which determines and stores a mean value of measured tares. Subsequently, the operation is switched to a second operational mode for a filling operation. In the second operational mode, no measurement of the tare is made, and the mean value is regarded as representing the tare of supplied vessels for purposes of a filling operation. After a given time interval or after a given number of vessels have been filled, the operation is again switched to the first operational mode where the mean value is again measured. If the new mean value is different from the previous mean value, the stored mean value is rewritten. By using the stored value, the filling operation is initiated at an earlier time than when the tare is measured.
