S-ar putea sa mai fie o problema: tensiunea livrata de sonda sa nu fie liniar proportionala cu cantitatea de combustibil din rezervor. Adica: 0 litri = 5V, 50 l =0V (rezervor plin), dar la jumatate (25 l) nu ai 2,5 V.Cam asa s-a intamplat aici: viewtopic.php?f=21&t=94505 Daca tot masori tensiunea sondei la extreme, fa si aceasta masuratoare cu jumatate de rezervor plin ca sa te asiguri de liniaritatea indicatiei.

La treaba asta ma gandeam si eu, dar sper sa fie liniara sonda aia.Cum prind ceva timp liber bag paratul de masura pe sonda si vad exact care este situatia.In cazul in care sonda este logaritmica as putea lua semnal direct de pe acul indicator din bord. ca ala are ceva electronica ce il comanda si nu cred ca merge si el logaritmic.
