[0002] The rotor scale is composed of a powder quantitative feeder, a ring-shaped balance rotor scale, a wind lock device and a microcomputer control part. The powder material is fed into the ring-shaped balance rotor scale by the powder quantitative feeder. The rotor scale impeller rotates to make the material flow evenly within a semicircle from the feed port to the discharge port. At the same time, the detected speed signal is sent to the instrument. After processing, the instantaneous flow rate and cumulative amount are obtained. The flow rate can be adjusted by controlling the feeding speed.
