Something has been bugging me about EFIS fuel computers (e.g. as in a Dynon D180). I assume most mechanical fuel level senders in an RV6A top out at some level below the full 19 gallons (due to dihedral). The level might be indicated as 13 gallons, when there are actually 17 gallons, for example. However, the fuel flow sender still measures consumption of the fuel that is above the sender's level.
Am I correct in thinking that fuel level and fuel flow are independent in EFIS systems? In other words, the fuel flow calculations (range, time, etc) don't affect the fuel level indications. Fuel flow calculations are only dependent on the number of gallons you key into the software, not the physical quantity of gallons, right?
