Abstract: Fuel adulteration and inaccurate fuel measurement are prevalent problems that affect vehicle performance, engine efficiency, and environmental health. These issues lead to significant financial losses for consumers and contribute to air pollution due to the use of contaminated fuel. This project presents a Fuel Analyzer System designed to monitor and assess fuel quality and quantity in real time. The system integrates multiple sensors, including density sensors, flow sensors, pressure sensors, and conductivity sensors, to detect fuel adulterants such as water and other contaminants, while accurately measuring fuel levels and flow.

The data collected by these sensors is processed and analyzed to provide users with immediate feedback on the quality and volume of the fuel in the vehicle’s tank. By leveraging advanced sensor technology, the system ensures precise fuel monitoring, enabling users to identify adulteration and discrepancies in fuel quantity. Unlike standard fuel monitoring systems, this system requires integration into the vehicle’s fuel system, offering a comprehensive solution for accurate fuel analysis.

The proposed system aims to enhance consumer protection, promote fair fuel distribution practices, and reduce environmental impact by encouraging the use of high-quality, unadulterated fuel. Through real-time monitoring and accurate detection, the Fuel Analyzer System contributes to greater transparency, efficiency, and sustainability in the automotive industry.
