FLOW CONTROL TRAINER (COMPUTER CONTROLLED SYSTEM) APPARATUS

Product Description

Description:

The present set-up is designed to study a PID ControlledFlow Process in the industry.

Water is pumped from the sump tank by means of a centrifugalpump to a Pneumatic Control Valve and after passing thorough the Rotameter itreturn back to the sump.

The Differential Pressure transmitter with an Orifice meteris fitted in the water line.

The flow of water in the line is sensed by the transmitterand communicated to the digital indicating controller. This measured variableis compared with the Set Point by controller and output is generated and givento I/P converter, which in turn supply the 3-15 Psig pressure to vary theopening of the Pneumatic control valve to eliminate the error observed.

As the opening of pneumatic control valve varies, the flowof water in the line gets effected.

This process goes on until the Set Point target is achieved.

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

Provided Rotameter enables to get the direct reading of flowof water in the line. These units along with necessary piping are supported ina well-designed housing and are fixed on base plate.

Experimentation:

To study the open loop or manual control
