After a proper configuration and connection you will be able to get values for two parameters:
❖Fuel level
❖Fuel temperature
Have in mind that if you connected 2 sensors, you MUST configure only 2 sensors. If you configure more
or less sensors, none of them will show the fuel level.
Also if you have few sensors connected and one is damaged or broken, the others will not show fuel level
as well.
