Fuel level calibration question

[airguy]

Dynon - with the standard resistive float sensors, during the calibration routine if only the empty and full points are set and the 2-gallon routine is not followed, will the system assume a direct linear response between the empty and full points based on the voltage difference and display the fuel level based on that?

No, Dynon Avionics engine monitoring systems it will not interpolate the points between beginning and end for fuel level. We do this because fuel tanks usually have a non-linear relationship between volume and vertical movement.

Actually, one other thought here. With a D10/D100 series, the system basically demands that you do incremental pours, so it's hard to get a two point calibration.

With SkyView, however, you can go through the calibration process, do just two points, and then go back in and edit the calibration afterwards (they're editable in SkyView). Use the sensor debug page to get the voltage when you are really full, and use the that as your second point. The system does a smart fit to the amount of points that are three, which is (necessarily) a linear fit if there are only two.
