Hi Svein,
I'm really not interested in another instrument =AD the Dynon EMS-D10A does
all of that plus more =AD I get live fuel flow, fuel level, litres used,
litres remaining. The only problem with my current setup is the float
sender =AD it only seems to reliably read between 20litres and 48 litres,
anything more or less than that doesn't register. Also, it really bounces
around in certain situations like a prolonged climb where it under-reads
terribly.
The Dynon totals up the fuel used, but it's not infallible =AD for example if
I put a jerry can into the system and forget to update the level count, or
if the fuel flow meter goes wrong. I'm looking for redundancy so I can
cross check litres used with the litres left in the tank. I like to have
the sight tube (unreliable below about 30 litres), plus the totaliser, plus
a level readout.
This became important just recently when we had a small "fuel crisis" panic
buying in the UK. All the mogas ran out, and my only option was to fly to
a
field with avgas. Fuel was low, so I emptied a few litres from various
jerry cans, and I had to unscrew the sender plate and look into the tank to
check I had enough to safely take off!
A friend runs a capacitance gauge from the link I posted earlier and
believes it to be very accurate indeed. For me, it will serve as one of
three ways to check fuel level.

Carl,
I installed the Princeton (? =AD memory fades=8A=8A) capacitive sender sold by
Europa when I purchased my kit in 2001, connected to Grand Rapids EIS. Not
happy with the sender, I believe it is very sensitive to type of fuel (moga
s
type and producer, 100LL) and possibly other factors.
Have you considered the FP-5 Fuel Totalizer from Electronics International?

I am VERY happy with this instrument. Very accurate (no calibration has
been required), easy to install, easy to use, and has the added value over
a
level measurement system that you get read-out of actual fuel flow (uses a
sender also in the return line) in addition to quantity remaining. Great
for optimizing cruise speed. Also other nice features. The only thing yo
u
have to remember is to update the fuel quantity on board after refueling
(you are reminded of this every time you switch on the avionics power).
Regards,
Svein
