ACRW-SYS1 Outline of the System　
The system calculates the feeding amount by measuring the time taken for the powder or grain in the weighing hopper to be discharged from the high to low level.To put the feeding amount close to the preset value,the speed of the motor for the weighing feeder is controlled.
While the weighing hopper is being charged from the low to high level,the motor for the
weighing feeder is driven at the proper speed. After charging is complete,the system restarts calculating the feeding amount while controlling the motor speed.

Features 　　
1． Through quick response and formation of a feedback loop the preset value is continuously followed.． 　　
2． Motor speed during charge (under no feedback control)can be corrected.　　　
3． Most suitable as a weighing system of small or medium capacity.
