| == Introduction to the Product ==
| |
|
| |
|
| '''DUT-E''' fuel level sensor is used for accurate fuel level and volume measurement in tanks of vehicles and stationary units. DUT-E helps determine current fuel volume and detect changes (such as refueling or draining) in the fuel tank.
| |
|
| |
| It is widely used in GPS tracking and vehicle telematics systems, either as an additional fuel sensor or as a replacement for the factory-installed sensor. When integrated into a telematics system, DUT-E provides reliable and precise data on fuel levels, helping detect fuel misuse and theft, and offering a comprehensive view of fuel consumption.

| == Device Configuration ==
| |
|
| |
| # Connect the DUT-E sensor to the device via RS-485 ports.
| |
| # Open the configurator tool '''GUI_v2/v3'''.
| |
| # Click on '''Connect Sensor'''.
| |
| #
| |
| # For **Automatic mode**, set the "Automatic Transmission mode" to hex format with a desired time interval.
| |
| # For **Request mode**, disable "Automatic Transmission mode".
| |
| # Click on '''Save to Sensor'''.
| |
| # Now use the '''QCOM Tool''' to verify that the fuel data is visible after proper configuration.
