Graeme,
I installed the Electronics International fuel flow instrument with
differential module:
http://www.buy-ei.com/Pages/FP-5P/FP-5P_Details.html
One transducer measures flow to the carbs, another measures the return flow
and the differential module sends the net flow data to the instrument. I
have used it for two years now, VERY pleased with its accuracy (easy
comparison of fuel used shown by the instrument and quantity to top up the
tank again). I have not done any recalibration. User friendly. Easy to
install. I placed one transducer between the engine driven fuel pump and
the right side carb, the other in the return line in the tunnel.
Great instrument for determining fuel efficiency (range) under various
conditions as you fly and showing remaining fuel. Only thing to remember is
to update the fuel quantity in the tank when you start the engine if you
have refueled since last flight - flashing light on the instrument reminds
you to do this.
Regards,
Svein

Just sorting the fuel system on my new build. I am considering including an
RS type flow sensor for future use but what confuses me on the 912 install
is that some of the fuel comes back which would make the reading useless
unless a return sensor was also fitted. This is the reason my fuel
calculator in my C42 is worse than useless. Any advice appreciated.
