Fuel capacitor converter question

More detailed info needed. What/who’s fuel gauge or EIS are you using? You mean not a float but capacitance setup? Me, no converter , what is it converting

I am using glass advance panel with an Engine Monitoring Controller. Yes, no float. Using capacitance setup. Thanks

Here's a vote against the Dynon converters. I couldn't get them to work well. They worked, just didn't have enough resolution mid-range to show correct fuel levels as they only used a small portion of the 0-5V range.

I replaced them with the Princeton 2-point converters, and those have worked beautifully for a decade now. I believe they may be under a different name now, you'll have to ask someone else. They do require power, ground and signal wires, though. +5V IIRC.
 
Yes, Red Avionics has the one you need to work with Advanced Flight System Monitor. "Vans Plates Converter"
That is what I have. You can see pictures though out my website.

Exactly how bad are the Dynon converters? Thats what I bought to integrate in my G3X system based on the recommendation of my Avionics guy. I know they work, but I haven't calibrated my fuel tanks yet to see how accurate they may or may not be.

They were $100 for a ship set vs. $400 for the RED ones, so unless they really, really suck I'll probably stick with them.
 
I calibrated my gauges in 5 gal. increments in both level and 3 point attitudes. Float gauges tend to read full until you have burned 5 gals. or so then are reasonably accurate. The Dynon converters have been trouble free and I consider them accurate within 2 gallons.

Hi, i would like to know if you have calibrate yours with dynon and G3x? in the setup what value do you have?

I just followed the G3x calibration process and did set points every 2 gallons. I'm afraid I didn't write down the set points in my build log and the plane is in the paint shop several hundred miles away so I'm not able to check. As I recall, the spread between empty and full was probably around a volt.
 
+1 for Dynon. Mine have worked great for 15 years.
I don’t believe using someone else's calibration numbers will help you much. Mine vary from left tank to right.
 
ex Princeton here, calibrated tail up/down with the 3GX, works beautifully.

The only caveat is that this calibration only works precisely for one type of fuel.
Calibrated mine using my usual Mogas 98, and when occasionally forced to refill using Avgas, the indications are off by some (don't ask which direction as last time my engine drank lead was a long time ago, and exceptional).
