ABSTRACT:
A weight-operated filling system of rotary type is disclosed which is adapted to detect the weight of a vessel and content thereof by means of Roberval weigher. In such system, the centrifugal force which is applied to the vessel and the content thereof causes a metering error, and accordingly the invention provides a rotation detector which detects the rotation of a rotatable member in which Roberval weigher is mounted. A detection signal from the detector is used to correct for the error to derive a true weight. A filling valve is closed to terminate the filling operation when the true weight reaches a given value.
