Filling device for simultaneous filling of several containers has residual weight difference values for all containers used for calculating valve openings for corresponding filling valves

摘要

The filling device has a number of filling locations (A,B,C), each with a weighing device (2) supporting a filled container (3) and a continuously controlled filling valve (5) supplied from a common liquid feed line (6). A control (9) operates each filling valve in dependence on the difference between the actual and required weight of the corresponding container, with the residual weight difference values for all containers used for calculating valve openings for all filling valves so that the containers reach the required filling weight simultaneously.
