Filtration

Two options are connected with filtering:

  • Option: Filter sensor values;
  • Option: Filtration level (0…255).

Enabling filtration and the filtration level setting

Copied!
... General settings → 'Calculate fuel consumption by sensor''Filter sensor values';
... General settings → 'Calculate fuel consumption by sensor''Filter sensor values''Filtration level (0..255)'.

When using the filtration make sure to:

  1. enable the Calculate fuel consumption by sensor option;
  2. enable the Filter sensor values option;
  3. set a value greater than or equal to zero in the Filtration level (0…255) field.

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.

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.

To disable the filtration completely, disable the Filter sensor values option.
