Description
The Flow Process Training System is a compact and mobile unit for a wide range of experiments in fl ow control. It gives students a greater understanding of the stability of simple control systems. The self-contained unit can perform many experiments. By connecting this to other products in the range further experiments are possible. For cascade control of fl ow and pressure, it can link to the optional Pressure Process Training System. For cascade control of flow and level, it can link to the optional Level Process Training System. For distributed control, it can connect to the optional Computer Control System. The main parts of the Flow Process Training System are: • Industrial controller with auto-tune feature • Two-channel chart recorder • A gap-type (rotameter) fl ow meter • Fixed orifi ce and pressure transmitter • Pneumatic control valve • Three-speed pump • Reservoir To carry out experiments, students fi ll the reservoir with clean water and prime the system. They then set the controller to regulate the fl ow of the water using a pneumatic valve. The gap-type flow meter gives a visual indication of fl ow. The fixed orifi ce and pressure transmitter give feedback to the controller. For a realistic experience, the equipment has industrial-standard instrumentation and parts. The apparatus includes two gate valves. One valve controls the fl ow at the output (drain) and the other acts as a flow-bypass valve. A chart recorder shows and logs the changes of the process variable (level) and the controller output.
