ABSTRACT: The liquid level controlling is useful and important phenomena in industrial, domestic and many other applications. We designed a system to control the liquid level of a container/boiler or any other type of tank. There are many techniques use to control the level of particular tank like PID and PI. We used fuzzy logic technique for liquid controller. Our FLC consist of two input parameters liquid level in the tank and the consumption of the liquid from the tank. To control these two input parameters one output parameter valve is used. The technique used by us involve the FIS with define rules
