ITALON FUEL SENSOR
Introduction to the Product
ITALON Fuel Level Sensors (FLS) measure fuel level in fuel tanks of the vehicles and stationary objects. ITALON FLS are connected to GPS devices which in turn transfer all the data along with the fuel information to a server part of the solution.

⚠️ Mandatory Save Command
After completing configuration, execute this command to save settings:
SET CUMR:2
Step 3: Verify Fuel Data Transmission
After configuration, the device starts transmitting real-time fuel data via telemetry packets.
🔍 Validation Steps
- Monitor server-side data packets.
- Confirm:
- Fuel data values are present.
- Updates occur at the configured interval.
- Values are within the expected range.
Note: If fuel data does not appear in packets, recheck wiring and configuration.
