Adtron’s Model 4021D Flow Control Set up Comprises of a differential Pressure Flow sensor with Orifice meter to measure the flow Rate. The flow of water is controlled by a Pneumatic Control Valve actuated by a I to P converter, Rotameter is provided to measure the flow rate. The system is mounted on a table top model with all necessary piping. The water inlet and out let are brought out through a manual control valve. Water at approx. 650 LPH has to be supplied to the system externally. The electronic panel comprises of ADC/DAC card with RS – 232 interface. Software is provided for experimentation, PID Control settings ( P, PI, PD and PID mode ) Data storing, Online data acquisition, Off line analysis, Printing of data’s can be done easily.
