I am installing the Dynon Skyview in my SS7 and was getting ready to install the optional fuel flow sensor in the fuel line on the engine. The only reasonable place to put it is in the fuel line coming out of the fuel pump just before the tee to the two carbs. Then I noticed that the fuel bypass orifice fitting is part of that tee, which sends a small amount of fuel back to the header tank. In other words, my sensor would be measuring total fuel flow INCLUDING the bypass flow. This would make the fuel consumption reading quite inaccurate. Short of completely reworking the very nicely done Rotax fuel line plumbing, I am not sure what to do.

Surely others with fuel flow sensors have run into this-what did you do?

Is it possible to program the Dynon Skyview to compensate (ignore) for the bypassing fuel? If the fuel pressure remains fairly constant from idle to full throttle then the bypassing fuel thru a fixed orifice will also remain constant (my engineering background tells me this). This would allow a constant flow rate to be subtracted from the total flow thru the sensor. Does anyone know if this is possible to program in the Skyview? Do any of you flying the Rotax 912s know if the fuel pressure remains constant thru the RPM range?

Any other ideas would be appreciated. Maybe John McBean will chime in-I know they have installed Skyview in several SLSA's.
