If there are many fake refills/drains in TT2 Fuel module or Fuel tank report, for example:

Specialist should apply standard fuel tank report template depending on fuel tank capacity and fuel level source (CAN/FLS).

1.Check what is MAX fuel tank capacity and Fuel level source:

2. Scroll down to “Fuel tank report parameters” at the bottom of the page and click on “Please choose a template”:

3. Select appropriate template depending on fuel tank capacity and fuel level source.

Use FLS templates if fuel level is measured from FLS:

Use CAN HCV/LCV templates if fuel level is measured from CAN:

4. Bellow Fuel tank report parameters:
1. enable Spike filter. (Fuel level value for coordinate is set to average (of coordinates before and after) if that coordinate (and only that coordinate) have fuel level value that is bigger than fuel variation + fuel level of the coordinate before);
2. Recalculate the data

3. Click on save.
