Filtration

:!: Note: Ellipsis () substitutes Unit properties –> Fuel consumption when indicating the option paths.

Two options are connected with filtering:

  • Option: Filter fuel level sensors values;
  • Option: Filtration level (0..255).

Filtration enabling and filtration level setting

... → 'Fuel level sensors' block → 'Filter fuel level sensors values';
... → 'Fuel level sensors' block → 'Filtration level (0..255)'.

When using the filtration make sure to:

  1. check the Fuel level sensors area (Unit properties → Fuel consumption);
  2. check Filter fuel level sensors values;
  3. set a non-zero value for the Filtration level (0…255).

Filtering should be used when it is necessary to remove erroneous values, significantly larger/smaller than the remaining values. During filtering median smoothing is used.

:!: Attention!

  • The value 0 in the Filtration level option is not the zero filtering, but the minimum possible filtering (for three messages — since this is the minimum amount of data required for median smoothing).
  • Any number from 1 to 255 set in Filtration level is multiplied by 5. The result number is the amount of messages that is filtered.
  • To disable the filtration completely, uncheck the Filter fuel level sensors values option.
