Good timely topic!
Full disclosure don't really follow the technical jargon so well - so make your response in simple "man in the street language" - Thanks.
I am using a Dynon Skyview, reading two cubes. One cube on main fuel supply to carbs and second on fuel return line.
My limited understanding of the Dynon adjustment, is that the second cube (return line) will somehow automatically subtract its reading from the total, thereby giving an inflight/ real time fuel consumption reading L/Hr.
I know how to adjust the Dynon (number of pulses).
My last aircraft had just one fuel flow sensor on the main fuel line. It was quite easy to get an accurate in flight fuel flow and total fuel used fuel remaining reading.
Dynon recomend a start number (pulses) for Rotax 912 ULS, which I used for both cubes (from aged memory 70000?)
Over a series of flights, I adjusted the main fuel cube (pulses) to reflect the total fuel consumed (measured by how much fuel to refill).
Total fuel consumed and fuel remaining are now quite accurate, however real time fuel flow makes no sense to me. It's consistently about 7 L/hr too high.
Should I be adjust the return line cube pulses?
If so, will this put the main line fuel adjustment out ie need further adjustment?😈
