The FL-1 and FL-2 are fuel level instruments featuring an LED analog display and a digital display. The FL-1 is for single fuel level while the FL-2 is for dual fuel level. They can display in gallons (one or one-half gallon increments), pounds or liters. Since the FL-1 and FL-2 do not incorporate any moving parts (needles, bearings, springs, etc.), there is little to go wrong or wear out. Instrument improvements allow for a new, easier and quicker fuel calibration procedure. The procedure also removes any non-linearity in the tanks and sensors. You may use as few as two calibration points or as many as nine. A New Programmable Fuel Slosh Stabilization feature has been added to increase user customization.

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 is not STC’d for installation in a certified aircraft.

FL-2CA: This model was designed to be used with EI’s Capacitive Fuel Level Probe (P-300C) from 6” to 20’ long. A P-300C/4 Module must be used for probes 6” to 4’ long.
FL-2RA-12: This model was designed to be used on a 12-volt system with a resistive fuel level sensor. The fuel level sensor’s resistance may increase or decrease as fuel is added to the tank and the maximum resistance must be between 90 and 270 ohms.
FL-2RA-24: This model was designed to be used on a 24-volt system with a resistive fuel level sensor. The fuel level sensor’s resistance may increase or decrease as fuel is added to the tank and the maximum resistance must be between 90 and 270 ohms.
FL-2M: This model was designed to be used with EI’s Magnetic Float Sensor (P-300M). The P-300M is an accurate replacement for a resistive fuel level sensor.
