6-1. Feed Weighing and Discharge Weighing
6-1-1. Feed Weighing
This method controls weight of the metering tank (e.g. hopper) as it is being
filled with raw material.
Example of Feed Weighing
In this example the metering tank is fed with raw material from the raw material
tank. At first, the feeding valves are to be fully opened to feed, and closed in the
order of large → medium, and medium → small at the time of Final-SP1, and
Final-SP2, respectively. The feeding valves are to be completely closed at the
time of Final-FF CPS.. The weighed raw materials are to be discharged to a
container by opening the Discharge valves.
