FLOW CONTROL TRAINER (COMPUTER CONTROLLED SYSTEM) APPARATUS

Description:

The present set-up is designed tostudy a PID Controlled Flow Process in the industry.

Water is pumped from the sump tank bymeans of a centrifugal pump to a Pneumatic Control Valve and after passingthorough the Rotameter it return back to the sump.

The Differential Pressure transmitterwith an Orifice meter is fitted in the water line.

The flow of water in the line issensed by the transmitter and communicated to the digital indicatingcontroller. This measured variable is compared with the Set Point by controllerand output is generated and given to I/P converter, which in turn supply the3-15 Psig pressure to vary the opening of the Pneumatic control valve toeliminate the error observed.

As the opening of pneumatic controlvalve varies, the flow of water in the line gets effected.

This process goes on until the SetPoint target is achieved.

A ball valve is also provided in thewater line to disturb the system and to observe the effect of disturbance. Asthe water returns in the sump tank again, the system operates in close circuit.

Provided Rotameter enables to get thedirect reading of flow of water in the line. These units along with necessarypiping are supported in a well-designed housing and are fixed on base plate.

Experimentation:

To study the open loop or manualcontrol

To study the proportional control

To study the two mode (P+I) control

To study the two mode (P+D) control

To study the three mode (PID) control

To study the tuning of controller (Openloop method) using Zeigler-Nichols method.

To study the stability of the systemusing the BODE PLOT.
