Controller board for Fuel Analyzer Photometer
Challenge
A Brazilian instrumentation company identified a market opportunity in the fuel quality testing sector but lacked the technical expertise to develop the controller board for their first product. They needed a portable, accurate, and reliable fuel analyzer that could be used at fuel stations across Brazil to ensure compliance with national fuel quality regulations. The key requirements were:
- Portable design for field operations
- Precise measurement of fuel composition ratios
- User-friendly interface for technicians
- Compliance with Brazilian fuel quality standards (ANP regulations)
- Reliable operation in various environmental conditions
Solution
I designed and developed a complete controller board for a Fuel Analyzer Photometer, creating a sophisticated yet user-friendly testing instrument. Key Features Implemented:
- Graphical LCD display and keyboard interface for intuitive operation
- Stable light source and precision optical sensor for accurate measurement
- Integrated power supply with battery backup for portable field operation
- Robust embedded firmware for reliable measurement processing and data management
Technical Implementation:
The system works by inserting a fuel sample between the light source and optical sensor. The controller board processes the optical data to measure water/ethanol or ethanol/gasoline proportions, comparing results against regulatory standards to verify compliance. The embedded software provides real-time analysis and clear pass/fail indicators for field technicians. Technologies Used
- Embedded C programming
- Optical sensor integration
- A/D converter and analog signal processing
- Battery management systems
- LCD display interfaces
Results
This innovative solution delivered significant business impact:
- Market Entry Success: Enabled our client to successfully enter the fuel quality testing market with their first product of this type
- Regulatory Compliance: Met all Brazilian National Petroleum Agency (ANP) requirements for fuel quality testing
- Operational Efficiency: Provided fuel stations with on-site testing capabilities, reducing wait times and improving compliance monitoring
- Business Growth: Established our client as a credible player in the Brazilian fuel testing equipment market
