Hello -
I have an issue with incorrect fuel tank readings. Issue resolved by re-calibration.

Thanks for the information. Is there any chance you can post your voltage readings for the levels? Mine are SO close together and I was wondering if yours are any different.
Are both you guys getting accurate reading from the tanks? If we put 42 gallons in and burn 21, the fuel flow transducer is right on the money but the tank gauges will, for example say that there are 5 gallons left in the left tank and 7 in the right. Mis-match is a big delta.
Your experience is normal. The changes between pours is small but measurable and goes out many decimal places, which cannot be seen in the calibration screen.
Thanks for posting this. I appreciate it. You are using the Dynon Capacitance to voltage converter, correct? Also, do your plate look like this:
Yes, to the Dynon converter and as I remember yes to the plates. It?s been 8 years since I built my tanks, I used Van?s plate kit. And the Dynon converter from 6 years ago. So things could have changed.
One note: after the second calibration, I was still not quite happy with the gauge readings, so I made some manual adjustments to the numbers you see. It took some time, tracking fuel burn, dip sticking before and after each flight, writing a log. And I was also adjusting the Dynon for the red cube fuel flow, that was easier.
