I recently flew an aircraft with a fuel totaliser.
What kind of engine was it? Modern engines (EI) use intrinsic calculations based on injectors.

Avgas and mogas are pretty close
Yes, that’s what I meant, thanks.

Makes sense.
Thank you all. So if I understand everyone correctly (and there seems to be some unity on this one!) Once correctly calibrated, the totaliser should give the correct fuel remaining onboard no matter that the fuel used may be avgas, moves or ul91 (ignoring jetA1) as it will be correctly measuring the volume of fuel used.
However for a given power setting one can expect to see different fuel flow rates because there IS a different volume of fuel flowing.
Thanks so much for the info.
LeSving it was a rotax 912s.
DA42 fuel totalizer data is based on FADEC output and does not feature any physical turbine.
