Adtron’s Model 4021B Level Control Setup comprises of a Measuring tank fitted with Level transmitter to measure the water level. The flow of water is controlled by a control valve actuated by an I to P converter. Rotameter is provided to measure the flow rate. The system is mounted on a table top model with all necessary pipings. The water inlet and outlet is provided through a manual control valve. Water at approx. 100 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. voltages.
