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.
