Another significant model which has been highlighted in this work would be controlling the tank level by using SCADA system. Such model could be performed in practical station, which concern with oil, water and gas tanks. The principle of motor working within the tank level model and the overall designed system can be as seen in picture.

When the tank is filled of these liquids it would give an indication for the filling within the SCADA system and this is done by giving the order by using the button of FILLING. The scenario of filling tank cab be illustrate in picture.

Meanwhile, the last situation related with the tanks are represented with the discharging of liquids. And this is done in SCADA system by using the command of DISCHARGE. This third scenario can be illustrated as seen in picture.
