Max,
I have the Electronics International FP-5 fuel totalizer for my 912ULS
installation. If your fuel system is per the Europa manual, you definitely
need return flow transducer (which is optional with the EI totalizer). The
return flow is substantial.
I fitted the feed flow transducer between the engine driven fuel pump and
the right side carb, and the return flow transducer inside the center tunnel
- I have a hatch in the fuselage bottom for access to whatever I have inside
the tunnel.
The system worked right out of the box, with no calibration necessary for
very accurate reading of remaining fuel. Great tool also for fine-tuning
speed vs. fuel consumption at various gross weights.
Regards,
Svein
