Short Description: Fuel Flow Calibration Checks
|
I've been bothered by the high fuel flow readings witnessed during initial trial flights, so today I decided to run a calibration check. See picture below for my set-up.
With a fuel flow sensor K-factor of 68,000 pulses per gallon (as per FT-60 Red Cube spec sheet), I measured an actual fuel flow of 11.6L/hr when the EFIS displayed 15L/hr. Hmmm, there is my problem.
I started adjusting the K-factor to suit actual measured fuel flow and ran another test. I will continue with this tomorrow.
