Introduction
This circuit contains two pumps which is used to fill the water in tank or other liquid.This circuit also contains the pressure switches,warning light,magnetic contactors,overload relays etc.This circuit is used to fill any liquid to any tank.In this circuit a warning light and a buzzer is connected which are used to indicate that the required tank is filled completely.
Explanation
This circuit contains the four pressure switches and two tanks.Every tank contains two pressure switches.One is installed on it's upper level and the other is installed in lower level of both two tanks.These switches are used to measure the level of the tank.When the pumps starts working the tank starts filling and the pressure switches starts measuring the level of the tank.when the water reaches to it's upper level and filled completely in tank,then the pressure switch turns on and the current now passes the circuit and a warning light starts indicating and also the buzzer starts indicating.

Uses
This type of circuit is used mostly in hoises and also for filling purposes in commercial areas and factories,industries etc.
