FL-2 Overview

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 (FL-2R-12 or FL-2R-24, depending on 12 or 24 volts), capacitive probes (FL-2CA) or 0-5 volt output, (such as with some Skysports probes (FL-2V). Please be sure to specify which model you need when you order your FL-2.

The FL-2 is not STC’d for installation in a certified aircraft.


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.
