| Description |
The Level/Flow Process Control System is a single loop system, using water as the process fluid, which allows study of the principles of process control using liquid level and flow rates as the process variables to be controlled.
-
This Control System includes:
- Basic Process Rig.
- Process Interface.
- Process Controller.
- Level Sensor Pack.
- Flow Sensor Pack.
- Digital Display Module.
- Discovery Software.
The system consists of a completely self-contained, low pressure flowing water circuit supported on a bench-mounted panel, making it suitable for individual student work or for group demonstration.
-
The circuit includes:
- Sump Tank.
- Dual-compartment Process Tank.
- Circulating Pump.
- Visual indication Flow Meter.
- Motorised linear flow Gate Valve.
- 3 Solenoid operated valves.
- 4 Manual valves.
- Pulse flow sensor.
- Potentiometer Float level sensor.
- On/Off Float level switch.
