Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.

The FL-1 offers pilots an accurate, stable digital fuel level for single tank configurations. Not only does the FL-1 display the tank level digitally, it also provides a 210° graphical arc for immediate, quick reference of the tank fuel level.
The FL-1 can be ordered to work with a resistive probe (FL-1R-12 or FL-1R-24, depending on 12 or 24 volts), a capacitive probe (FL-1CA) or a 0-5 volt output such as with some Skysports probes (FL-1V). Please be sure to specify which model you need when you order your FL-1.
The FL-1 is not STC’d for installation in a certified aircraft.
When in flight, fuel will slosh around in the aircraft fuel tanks, creating irritating readings that constantly jump around. The FL-1 has a Fuel Slosh Stabilization calibration point that averages fuel level readings, creating a much more stable, but still extremely accurate fuel reading. Calibrate between a couple of seconds all the way up to over a minute of fuel slosh averaging.
The FL-1 allows installers to program from as little as two all the way up to nine fuel level calibration points in the fuel tank. This flexibility eliminates inaccuracies due to non-linear fuel tanks.
The FL-1 is a simple instrument to install and program. Clear step-by-step instructions make programming the instrument easy to calibrate to your fuel tank senders.
The pilot can easily select between displaying fuel level in Liters, Gallons or Lbs with a switch on the front of the instrument panel.

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Your products always work great! Great customer service and a quality product that we have used for years.
Nice bright display.
Good engineering support.
Excellent customer service. Without a doubt the best aviation part I have purchased.
You folks do a great job. Keep up the good work.
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
EI’s products are the only ones we recommend to our customers.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Great product and excellent customer service!
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
