Given that (a) petrol has far more low-temperature volatiles than diesel and (b) fuel gauges have been safely driven by direct current through an exposed resistive wire and a sliding contact for about a hundred years in cars... why reinvent the wheel?
I believe that aircraft use capacitive methods - a rod inside a tube with a small hole to vent will damp out splashing. |

Easy solution: Old fashion snowmobile fuel gauge, sensor is inserted to tube which is mounted to filling cap, also gauge needle is on top of filling cap. Can be inserted to small tank easily.
Insert magnet to needle, measure needle angle with magnetic encoder, for example http://www.austriamicrosystems.com/Prod ... c-Encoders |
