Fuel Level Sensor (FLS)
Fuel Level Sensor (FLS) in a Monitoring System
A Fuel Level Sensor (FLS) is a device designed to measure the current volume of fuel in a vehicle’s tank. In monitoring systems such as Wialon or Wiafleet, the FLS is a critical component that ensures accurate fuel consumption tracking, helps prevent theft, and enables analysis of vehicle efficiency.
How It Works
The FLS is installed in the fuel tank and measures the fuel level, converting it into an electrical signal (voltage, current, or frequency). This signal is transmitted to a GPS tracker, which then sends the data to the monitoring system server. The data is processed and displayed as:
-
Current fuel level
-
Fuel consumption graphs
-
Events (refueling, fuel drain)
-
Fuel efficiency reports

Configuration in the Monitoring System
Once the FLS is installed and connected:
-
Create the sensor in the system (set the type: “Fuel Level Sensor”).
-
Input or upload the calibration table.
-
Set measurement units (typically liters).
-
Specify additional FLS parameters as required (such as filtering, offset, sensor input type, etc.).
Benefits of Using an FLS
-
Accurate tracking of refueling and fuel drains
-
Prevention of fuel theft
-
Analysis of fuel efficiency
-
Reduced operating costs
-
Greater transparency in driver and vehicle performance
