The control computer, feeding facility with 2 pneumatic gates, weighing sensor, and pressing bag structure comprise the scale. It is used for good flowability powder and granular. For the bad flowability powder, the scale is equipped with belt or screw feeding. 
The packaging scale is controled by SCM, and the mechanical and electric device work together with cooperation. The characteristics are high precision, easy operation, and reliable performance.

Advantages:
1．The height is 2.0 meters, and is convenient for any user.
2．Connected with the hopper by plug-in mounting style.
3．The packaging bag as the weighing hopper is clmped on the scale while packaging.
4．The demarcrate is numberial, easy to debug, and reliable.
5．3 reliable electric relays in the control system.
6．One sensor with high precision, and easy to debug.
7．Big & small gates to control the flow, assuring the dynamic precision.
8．The program is controlled by computer, assuring accuracy.
9．Sample mechanical structure, which is no need to maintain.
