Hardware Tank
(a)
Channel E01 set for a tank
with a resistive fuel level sen-
sor for a measuring range be-
tween 0 and 400 Ω.
(b)
Channel E02 set for a tank with
an active sensor (e.g. a capaci-
tive sensor) with voltage output
in 0-5V range.

Tank Calibration in Steps
This approach usually gives the best results as it takes into account
tank shape, sensor installation and sensor specific response at the
same time. Procedure given next shows principle for the tank 1. If
you have two tanks, the procedure must be repeated for the tank 2.
1. Have a notebook and pencil at hand.
2. Make sure you have enough fuel and enough cans ready.
3. Make sure you have your cans calibrated and marked. 10 liter
marks are sufficient.
Do not try to be super precise.
Fuel
sensors are not very precise. The maximal number of measuring
points is 18. In practice, 5 points are usually enough.
