Hi,

I installed FMB140 with a CAN connection in a many trucks like scania fh and mercedes actros and it returns the fuel level in percentage .but it is not precise like when the trucks are moving the fuel level let say it's 100 % for one moment, it  reduce to 95%  and then it returns to 100% .

this is a big problem for us cause we calculate   the spent fuel and when the fuel level is not correct it will return wrong value.

by the way 1% of the tank can be a 6 L so it need to be precise at possible

Best regard
