You have to calibrate them over time by adjusting a constant (K factor) based upon how much fuel is ACTUALLY used and how must is measured to have been used.
......then a formula is used to adjust this factor which is entered into the fuel computer.
Thank you, this is interesting. I expected that the flow meter will be adjustable. However, it is probably not user adjustable. What will the shop need to know as I will go for the ARC renewal in October?
