Cool new CIES fuel senders in a RV 9a

presently my fuel indication is awful but I am glad I have the G3X fuel page

Is there any experience with these new CIES fuel senders in a RV 9a already out there?

thanks Pit

I talked to them at Oshkosh and saw the system in a demo they had set up.
It seems it's not out yet, but they do have a couple people testing them in real aircraft. If I understood correctly one could buy the certified system and use it in an RV, but that'd be something like US$300 per sensor, and they're working on making a cheaper non-certified version.

The install will be non-trivial, simply because they use *two* senders, one on each end of the tank, to measure the full range (so dihedral is no longer a factor) - meaning another hole on the other side, possible opening up the tank to install nutplates, etc.

That said, I liked the "solid" look of the system - the inside (that goes into the tank) looks like a solid metal block with no moving parts other than the arm.

I use the system in an -10. I have two senders each tank (inboard/outboard). Very accurate, no fluctuation, coupled to G3x.

Are you one of the testers they mentioned at OSH, or is the system available already?

I was probably the first RV-10. We recorded the fuel measurement for Scotts chip. Measured voltage every two gallons, then flashed chip, then reinstalled. Scott now has the information to provide hardware for any -10 (vans has a different sender for each side rather than the same sender for both sides). There is something called a "Cessna fuel nut ring" that works great for Vans/Scott's senders (you don't use the individual nut plates, rather the nut ring - solid one piece ring that seals easier).

Hope this helps.

Interesting. To insert that nut ring you still had to open up the tank, right? Or was it an easy retrofit somehow?

Yes - we installed an inspection hole in back of tank to install ring.

Thats a big deal for a retrofit, isn't it? Do you know if Cies would provide a single sender for each tank. I can live with accuracy when the fuel is nearing the lower levels.

Thanks Pit

You can use the Cies system with one sender per tank. This would still be superior to any stock sender hands down. I would absolutely prefer and recommend one Cies sender over stock Vans units.

Thanks Evolution10,
Good advice, thanks. Do you know whom to contact at CIES and who is probably familiar with the set up in a RV9 with a G3X?
