Abstract

Flow of paint colour bases is automatically controlled to ensure correct measure. An electronic comparator circuit compares actual quantity against a demanded quantity and employs the difference signal to control opening of a valve. Contents in a recipient are weighed using an electronic weighing machine whose output signals are applied to counters to give actual weight and flow rate. A digital comparator operates a switch when the required measure is obtained or exceeded. A comparator compares the actual and demanded measures and the difference signal is amplified to drive a motor controlling a valve in a reservoir outlet.
