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 crotroller 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.
