Abstract
A system for continuously charging containers with a flowable substance including solid material, has a first pipe, a flow sensor for detecting substance flow in the first pipe; a plurality of valved second pipes each communicating with the first pipe and extending into a respective container; a level sensor associated with each second pipe for directly responding to a predetermined height level of the solid material accumulating in each respective container; and a control arrangement connected to the flow sensor, the level sensors and the valves of the second pipes for shutting off the valve of that second pipe through which charging was in progress and simultaneously opening the valve of another second pipe which is associated with an empty, standby container, at the moment when the level sensor associated with the container undergoing charging indicates that the solids reached the "full" level, while, at the same time, the flow sensor continues to indicate substance flow.
