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.
