This project aims to develop and repair the demonstration set of measurement level and control and study on PID control principle.
Measurement levels using transmitter set 4-20 mA signal to level controller and level controller sent voltage signal to control speed DC motor.
Circuit using PWM power control effect pumping to get the height of the water level 0-100% water level control using PI and PID control manners.
To control the water level, according to the setpoint.
