Automatic Water Level Controller

In many homes and other public places, groundwater is used, which is pumped up to overhead tanks using water pumps that are controlled by electric motors. Controlling the pumps is often a necessity to avoid wastage of water.The Water Level Indicator includes a simple mechanism that helps to detect and indicate the water level in an overhead tank or any other water container. The sensing is done by using a set of nine probes which are placed at different levels on the tank walls.  Two Types of Control:  1.    Manual Control:This control function or the interference to the process is introduced by an organization of parts (including operators in manual control) that, when connected together is called the Control System. 2.    Auto Control: Due to its efficiency, accuracy, and reliability, automatic control is widely used in chemical processed.
