Title:
METHOD FOR CONTROLLING DISCHARGE FLOW RATE IN A LOSS-IN-WEIGHT SCALE
Document Type and Number:
WIPO Patent Application WO/2021/190486
Kind Code:
A1
Abstract:
A method for controlling a discharge flow rate of a loss-in-weight scale is provided, wherein control outputs are continuously changed to save the time necessary for data stabilization, and a curve of relationship between the discharge flow rate and the control output is obtained by using the functional relationship between the control output and time and the functional relationship between the material weight and time. The discharge flow rate can be precisely controlled by directly selecting or inputting a value of the control output, to achieve the objectives of direct controlling and of avoiding the time for data stabilization.
