The only analogy to draw here, as there are no RV Pireps, is that current production or retrofitted Cirrus SR20 or SR22 have these installed -
In these aircraft - fuel level became newsworthy .
Plane and Pilot
The solution did find a problem with Cirrus and other OEM's and an appreciating audience.
By any and all standards we don't have issues like 1,2 or 3 -
What we report is an accurate fuel level remaining and it matches a computed fuel level remaining from an accurate fuel flow transducer and instrument. If there is a discrepancy fuel level to fuel remaining - you are losing fuel (Vented, Bad Cap, Fuel pump leak)
I am running a performance tests to solve an interesting multi tank fuel level issue - My stick gauge is repeatedly measuring the same displayed fuel value - during vibration I get a peak to peak average -
If the senders in your aircraft have a dead zone that is not a characteristic of all senders nor is it a universal to all senders regardless of how they derive the fluid level.
Our senders have floats but our measurement method is entirely different to any float sender you have held - This is not your average float sender. Watch the attached video and you will see what we are talking about. Using this technology is a CiES patent for fluid measurement
