Abstract

The paper is mainly concerned on Liquid level control systems which are commonly used in many process control applications to control, for example, the level of liquid in a tank. Liquid enters the tank using a pump, and after some processing within the tank the liquid leaves from the bottom of the tank. The requirement in this system is to control the rate of liquid delivered by the pump so that the level of liquid within the tank is at the desired set point. IMC tuned PID algorithm is implemented in MICROC programming language and it is loaded into the PIC microcontroller. The controller generate the output according to the error signal and derives the system towered the zero error. It is also interfaced with PC through MAX232 and DB9 connector for system identification and the observation of output of the system.
