Liquid level indicator circuits are highly useful to monitor the level of liquids present in a tanks where access to the tanks are difficult. This circuit uses pressure sensor to sense the level of liquid in the tank which eliminates the drawbacks such as: corrosion of the sensing electrodes, ionic conduction property of liquid etc., which were used in the primitive liquid level indicator circuits. Also  the alarm in this circuit offers the added advantage of alerting the user to turn OFF the liquid pump or valve.
