The full-automatic control pipeline systemprovides a touch screen for control box on jobsite. In
production, all operations of extruder system, such as startup and shutdown of the system, flow rate
of the materials, addition of the water and steam are controlled by the touch-screen control system.
The computer directly controls the Flow Control Unit and then the information is fed back to the
computer through the Flow Checking Unit to form a closed-loop control. The principle is shown in
