Flow and level control stand Mod. FLC/EV is a training system designed to teach the principles of industrial process control. The stand uses a borosilicate glass column fed by a central pump connected to a water tank. A recirculation pump returns water from the column back to the reaction vessel. The flow rate and column level can be precisely adjusted using pneumatic valves, and a SCADA software package for control and data acquisition allows the system to be monitored and controlled via a computer.
