Abstract

PURPOSE: To measure instantaneous weight flow rates by controlling a weight corrector by the use of the pulse signals from a powder feeding machine.
CONSTITUTION: A feeder 1 is rotated by a motor 2 to supply powder. The volume flow rate V of thd powder is proportional to the rotating speeds of the motor 2. A pulse transmitter is mounted to the feeder shaft to generate the pulse signals of frequency F1 proportional to the flow rate V. The signal F1 is converted 5 to analog voltage, which is then converted 7 to a frequency F2 via weight corrector 6. This signal is then supplied to a comparing counter 8. On the other hand, the feeder 1 is placed on a balance 4. The balance 4 generates signals at weight W + G and weight W respectively. The time interval thereof is converted to the signal for controlling the motor 61 by a time difference detector 9. The output voltage of the corrector 6 is indicated in an analog indicator 10 and the pulse signal of the converter 7 by a digital indicator 11.
