Automated ME FW Filling for Expansion Tank

Abstract

Fresh water expansion tank has been an important part of the cooling system for the main engine. It helps to cool down the jacket cooling water temperature through circulation and gravity. The tank is normally found at a high distance away from the main engine. However, it is not very safe and efficient as we have to top up the fresh water in the tank periodically due to evaporation, not to mention that the tank is fit in a tight and uncomfortable space. This paper is aim to design a system where the level in the expansion tank can be filled automatically with the help of microcontroller unit based (MCU) system. The system is simulated with Proteus software and the program has been compiled in the PIC C compiler. This paper will offer a system where Fresh water will be refilled automatically to expansion tank without any manual help.
