Configuration of Omnicomm LLS 5 sensors

Set up configuration parameters as described below:

Address (from 1 to 254) – set the network address of the Omnicomm LLS fuel level sensor. When several sensors are connected to one external device, the network addresses must be unique.

Automatic adjustment — enable this option to automatically correct measurements when the dielectric constant of the fuel changes. When auto-adjustment is enabled, level variations caused by fuel thermal expansion are also taken into account, meaning the displayed level will reflect the current temperature.

When using auto-adjustment, consider the following:

  • For the Omnicomm LLS sensor to automatically correct its calibration values, the vehicle’s fuel tank must be completely filled during operation.
  • When the fuel tank is fully filled, the maximum length of the sensor’s measuring part that remains above the fuel must not exceed 10 cm from the sensor flange.
  • If the vehicle is operated with an insufficient fuel level in the tank, auto-adjustment cannot be performed.

Auto output – select:

  • No output – autonomous data output (without request) is not performed.
  • Binary – autonomous data output in binary format.
  • Character – autonomous data output in character format.
  • Data output interval (from 1 to 255 seconds) – set the interval for autonomous data output.

Output interval - determines how frequently the LLS sensor sends data to the connected device. Shorter intervals provide more frequent updates but may increase data traffic. Longer intervals reduce traffic and power consumption but delay updates.

Min level (from 0 to 1023) – select the minimum reading of the LLS fuel level sensor. The default value is 0.

Max level (from 1 to 4095) – select the maximum reading of the LLS fuel level sensor. The default value is 4095.

Baud rate - select the speed at which data exchange with the external device will be performed. The default value is 19200 bit/s.

Filtering – set the output signal filtering parameters:

  • None – no filtering is applied. Used when filtering is performed by an external device.
  • Minimum – filtering is used when installed in stationary fuel storage tanks and low-mobility equipment.
  • Medium – filtering is used when the vehicle operates under normal road conditions.
  • Maximum – filtering is used when the vehicle operates under harsh road conditions.
