| Subject: | Re: Mod 60 Europa Fuel Gauge |
I mounted my float gauge just to the right of the headrest. There was room for
it to reach the bottom of the tank straight down. No regrets on this. Has worked
fine for 11 years but even with the more open access it's still very fiddly
to fit the flange. I had to change the gasket a couple of years ago.
Putting it there also gives better visibility of the inside of tank when the sender
unit is out (easier to fish out the washer you drop trying to install the
flange !)
I put my unit in before it came a Europa supplied kit so there is a chance the
dimensions are different now, but I assumed it was the same unit.

Hi Alan
Talk to Pete Smoothy at Airworld [uk] 01296 714900, I have one of his
"Capacitance" fuel gauges fitted, not expensive, so I would not mess about
but fit the complete system.
My sender unit is mounted on an inspection plate sited middle top of tank,
the probe was bent so that it measures fuel in the main tank only.
Best of luck

I've never used a capacitance sender, but I think they can be cut to size if
they're too long?
Could that help at all, or maybe I'm not following close enough here..
//
tell me what the depth of the tank is at the centre, Maybe I can mount it at
an angle or find a sender or something that will do .

Hi Ferg!
Sorry, but there is no Ground but The Ground in a composite aircraft!
That is to say, the negative side of the battery.
>From that it is simply a matter of practice in
minimizing the resistance back to that point. Noise is created when changing
current flows move across a resistance, and those changes in current occur
at high enough frequency to radiate to adjacent conductors.
Prevention of noise therefore seeks to minimize resistance to ground, and
improve shielding. Ira
Ira,
Quite right regarding the term "Ground" and its complications.
SO I added the UK 'earth', trying to show that it's not so simple when
radios are added. Radiating to adjacent conductors is OK provided they
aren't part of a radio installation. The purpose of the coax is to shield
such conductors from noise nearby. That can be accomplished only if the coax
is 'grounded' to the radio's prescribed point. Often, installations design a
circuit to forestall noise coming from the aircraft ground and so direct
coaxes to a radio ground, not the aircraft one. Old-style strobes can bang
out mighty peaks - and added to the audio noise.
What we need is another word for ground/earth and all I wanted
to do was suggest strict attention to installation instructions.
Cheers, Ferg

Hello Alan,
I did MOD60 on my last Europa and used the Airworld capacitance probe bent and
cut to length through a new hole near the RH seat headrest. 3 reasons for choosing
the capacitance probe: 1) i think it and the supplied gauge are more accurate
than the float type, 2) if i ever got water in the tank the capacitance
gauge would go full scale - so an indication in all circumstances other than
'just filled up with fuel' - that water may be present and 3) i already had the
float type in the LHS of the tank as well - AND the manometer quantity indicator
- so I had several sources of info to cross-check with - yes i'm paranoid
about the shame of inadvertently running out of fuel! Based on that experience,
if i had to choose one method, I'd choose the capacitance probe.

I dont like the sound of a 'forest of tabs under the panel" unless there are at
least two, a quiet ground and a noisey ground and both going back to meet at
the battery negative with as thick as you can. transponder, fuel pump, trim and
anything else noisey such as giros away from audio/radio and things that just
need a reference.

Hello All.
My plan is to try to contact Avalec again next week, Failing this the Air World
complete unit,
The plan would be to make up from plastic coated cloth and model aircraft tubing
a small umbrella with fishing line connected to each rib going through the canter
tube so as to pull it closed, this inserted through my original hole and
opened, it will also float on the fuel. this will catch any debris fall from
my re shaping the hole with hand tools.
Then withdraw the umbrella and fit the sender,
It will be bent to go down into the saddle of the main tank.
Alan
PS
It would be nice if i could connect the Airworld senders wires and joint the to
the Avelac wires which are already there, maybe it will work with the avelec
gauge which has an adjustable processor, maybe worth a try.

That is OK if you only use one type of fuel. If you calibrate it with Mogas
and then use Avgas you will get an inaccurate reading.

Hi All.
My plane is certified for Avgas and Mogas, labels by filler cap.
I use Mogas so will calibrate it for that.
Flow meter far more accurate than any gauge, so I can live with a small error on
the fuel gauge.
Fuel gauge just a back up, but shows if I have a punctured tank but not expecting
any dog fights.
Alan.
Maybe a ridged sender at 30 degrees will touch the bottom of the tank from the
middle.
If anybody building could look at the tank and "eye it up" so see
would be useful.
Alan
