- Omnicomm LLS/LLD: The interface is used to connect Omnicomm LLS fuel level sensors or Omnicomm LLD fuel volume indicator.

Now refer to “Fuel Level Sensors”:


Data Source: Select the type of fuel level sensors. Here are the available options:

- Digital LLS: This is for Omnicomm LLS fuel level sensors;

- Frequency LLS-AF: This is for Omnicomm LLS-AF fuel level sensors;

- Vehicle Sensor: This is for the vehicle's standard factory fuel sensor;

- CAN Bus: This is for connecting to the CAN bus;

“If you are connecting either Omnicomm LLS or Omnicomm LLS-AF fuel level sensors, you will need to configure the following parameters:

- Filters: Enter the size of the internal filter you intend to use. Here are the available filter options:

- Filters Off: Filtering is performed only according to the Omnicomm LLS sensor settings;

- Weak: Use it when installing sensors in stationary fuel storage objects or low-mobility equipment;

- Medium: Use it for vehicles that operate under normal road conditions;

- Strong: Use it for vehicles that operate under normal and heavy road conditions;

- Maximum: Use it for vehicles that operate under heavy road conditions and/or when employing a vehicle's default factory fuel sensor with analog output.
