I've just started flying an RV-7A with Grand Rapids displays and Van's
float type sensors. I have a couple of questions for people who have a
similar setup:
1. What did you find the maximum indicated fuel to be ?
2. Did you find the GRT recommended calibration to work for you ? There
are two of us on the field and neither of us have gotten satisfactory
results. Any alternative methods appreciated.

I have an 8A with float sensors and the Grand Rapids EIS. I find the fuel
level indication to be quite accurate following the calibration as
recommended by Grand Rapids. I set up the float senders to be accurate at
the bottom end of the tank level as the sensor does not have the range to do
the full tank level. I did the "one gallon at a time" calibration of the
EIS, logging down the EIS reading at each gallon. From this data you create
a line equation just like you did back in High School algebra: Y=mX+B, where
Y is gallons, m is the slope of the line, x is the reading you got while
calibrating, and B is the offset so that 0 gallons reads out as 0. You set
m and B as constants in the EIS so that your panel reading is in gallons.
Have the plane level when you do this calibration data run.
On my standard tank, readings go from 0 to 13 gallons. Any level above 13
gallons just reads 13 gallons. On the flop tube tank, readings go from 0 to
16 gallons. The senders are mounted in different locations in each tank,
thus the difference in ranges.
