DIGITAL FUEL LEVEL INDICATOR

The Digital Fuel Level Indicator from Mercetech Innovations is a high-accuracy digital fuel monitoring solution designed to work seamlessly with fuel level sensors.

  • Supports passive mode with external controllers.
  • Functions independently in active mode.
  • Displays volume in percentage (0.1% resolution).
  • Indicates volume in liters (1 ml to 10 liters resolution).
  • Easy-to-read digital display.

Key Features & Technical Highlights

1. Clear and Accurate Fuel Level Display

The Digital Fuel Level Indicator features a high-visibility 4-digit LED panel that displays:

  • Fuel level in percentage format with 0.1% resolution
  • Fuel volume in litres (with resolution from 1 ml to 10 litres depending on tank size) This ensures fuel data is immediately understandable and actionable for drivers and fleet operators alike.
2. Reliable RS-232 Interface with Standard Protocol

This indicator communicates with compatible fuel level sensors via a wired RS-232 digital interface using the EDE (LLS) protocol. The result is fast, stable data transmission and precise calculations of fuel volume values from the sensor input signals.

3. Dual Operation Modes – Passive & Active
  • Passive mode: Works with external controllers or telematics systems that interpret fuel data
  • Active mode: Functions independently to display fuel levels without external systems This flexibility allows easy integration with a wide range of telematics platforms and fleet management hardware.
4. High-Resolution Digital Data Processing

With support for 10-, 12-, and 16-bit data input, the indicator offers high-fidelity interpretation of sensor values, increasing the accuracy of readings especially in dynamic fuel usage scenarios.

5. Robust Performance in Extreme Conditions

Built for real-world applications, the digital fuel gauge operates reliably across a wide temperature range of -40 °C to +75 °C, making it suitable for vehicles, industrial equipment, generators, and outdoor installations.

6. Wide Operating Voltage & Low Consumption

With a flexible supply range of +9 V to +36 V DC and efficient current consumption (≤ 30 mA), this indicator can be used across automotive, heavy vehicle, and stationary fuel systems without requiring specialized power converters.
