The FL-2 offers pilots digital fuel levels, with unprecedented accuracy, for dual fuel tanks. Not only does the FL-2 display each tank digitally, it also provides 90′ graphical arcs for immediate, quick reference of each tank’s level. The FL-2 can be ordered to work with resistive probes for 12 or 24 volts.
The FL-2 is not STC’d for installation in a certified aircraft.
Analog Display 210 Degree, analog arc with green, yellow and red LED’s.
Digital Display Large, crisp, LCD display with adjustable backlighting for night operations.
Fuel Slosh Stabilization When in flight, fuel will slosh around in the aircraft fuel tanks, creating irritating readings that constantly jump around. The FL-2 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.
9 Calibration Points The FL-2 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.Easy Programming Interface The FL-2 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.
Selectable Units The pilot can easily select between displaying fuel level in Liters, Gallons or Lbs with a switch on the front of the instrument panel.
Dimensions: 2.5″ x 2.5″ x 3.65″ Depth, 2.25″ Bezel
Analog Display: Two sets of 7 High Intensity Light Emitting Diodes (LEDs) in 90 degree arcs with Intensity Control Line available for dimming. Sequential flash test on power up.
Fuel gauge is very functional. It can be calibrated reasonably easily. It gives a complete picture of your fuel situation at a glance. Each tank is calibrated separately and they can be different sizes and configurations. it is set up so you can revise single or multiple calibration points without draining the fuel from the tanks and starting again from scratch. This feature is very useful if you make an error part way through the calibration.

Q: Does the EI FL 2RA DUAL FUEL LEVEL RESISTIVE 2-1/4 NON TSO include sending units? Part # 11-03789
Per the supplier: No, it does not include the sending units.
Q: Does the Electronics International FL-2RA-12/24 Dual Fuel Level Resistive gauge have an STC to allow it's use as
a replacement for a Cessna 182 original gauge?
The Electronics International FL-2RA-12/24 Dual Fuel Level Resistive Gauge is NON-TSO'd and cannot be a replacement gauge for a Cessna 182.
Q: Which probes can I use for the EI FL 2RA DUAL FUEL LEVEL RESISTIVE 2-1/4 NON TSO?
The EI FL 2RA is designed to work with a resistive style fuel level probe. EI makes the P-300M part number 10-05097.
Q: Good morning! Are these instruments now TSOd? You say it includes all documents and certificates. Thank you!
These instruments are still experimental only. The web page overview has now been updated to better indicate this status.
Q: Will this gauge work with 13.2 to 14.6 volts, as commonly seen when using an EarthX battery?
This unit will have no problem working properly in your aircraft, with that voltage.
