Hi Raimo,
This is a nice looking bit of kit. Curiosity took me to the FDS website
for more info and having downloaded the manual, I notice that they
specify a second FT-60 "red cube" flow transducer should be used in the
fuel return line when used with a Rotax 912x installation. How did you
get away with using only one and still maintain accuracy?

Nigel,
There is a mod 12209 approved by FAA stating that for 912ULS a single
transducer could fit as the variations of the quantity of fuel returned
to
tank are small (but dependant of the variation of power setting). I
understand that the tuning of factor K should cover it. The same mod
states
that 2 transducers are mandatory for the 914.
Raimo, did you measure the discrepancy at various power setting?

Raimo. Thanks for that thought, but I doubt that I will have strength left in my
arms at that age to push the wheels of a wheelchair with two sitting on it together.
However we are not talking about my old arms, but the lovely legs of my other girlfriend
Europa G-EIKY. If they are long enough for Remi, then he is welcome
to have them; to enjoy their supple strength.

I made my experiences with the installation of only one transducer.
I am using the floscan transducer and a separate fuel computer.
The quantity of fuel that returns may nearly be constant ( not in my installation,
as the fuel pressure is for any reason not always the same ) but you can only
trick the computer with an matching K-factor for only one defined power setting.
One of the most important questions to the fuel computer for me is: how much fuel
is left in tank after for example two hours flying?
But in a flight we use different power settings so the number the computer showed
was rubbish.
So I redesigned the fuel routing:
The fuel line from the mechanical fuel pump now goes all the way back through the
fire wall to the cavity where the fuel select switch is.
There I installed a y peace. One line goes with the restrictor in it back to the
tank while the other goes in a strait line and with the transducer in line back
through the fire wall to the carburetors.
So only the fuel used by the carburetors is measured and the accuracy is outstanding.
After burning 40 liters there is only a discrepancy of half a liter.
And I have too all the benefits Raimo mentioned and I agree with him that this
system should be mandatory.
Sorry for my bad phrasing.
Juergen
