ABSTRACT:
Apparatus for controlling the rate of flow of a powdered solid material such as flour, comprising a load cell supporting an inclined plate onto which the flour particles impinge after falling through an inclined gate valve. The output of the load cell is fed to a control circuit including a direct proportional control section and an integrated error section with a monitor circuit sensitive to excessive integrated errors. The control circuit acts on an electric motor controlling the opening of the gate valve to maintain a predetermined rate of flow.
