Dynon Avionics does not sell fuel level sensors.
The FlightDEK-D180 supports both resistive type
sensors as well as capacitive sensors which output a
voltage (e.g., Princeton). If you have a capacitive
sensor which does not output a voltage on its own,
you may be able to use Dynon’s Capacitance-to-
Voltage Converter. Read the relevant section below
for the type that you are installing.
Once you have installed your fuel level sensors, you
will need to calibrate each of them, as described in
Fuel Level Calibration on page 6-5.
RESISTIVE FUEL LEVEL SENSOR
You may connect up to four resistive fuel level sensors to the FlightDEK-D180. Simply connect
the output of the sensor you would like to be Fuel Level 1 (left tank) to pin 20 and the sensor you
would like to be Fuel Level 2 (right tank) to pin 21. You may also connect third and fourth fuel
level transducers to the general-purpose inputs of your choice. See the General Purpose Inputs
section on page 3-13 for more information.
CAPACITIVE FUEL LEVEL SENSOR
Capacitive fuel level sensors are only supported on the Fuel Level 1 and Fuel Level 2 inputs.
Additionally, your capacitive sensor needs to output a variable voltage within the ranges of 0-
5Vdc. First, supply the sensor with power according to the manufacturer’s instructions. If the
sensor manufacturer requires a sensor calibration, perform that calibration first. Connect the
sensor’s output to pin 20 or 21, depending on whether you want the tank to display as left (Fuel
Level 1) or right (Fuel Level 2) tank. Do not connect capacitive fuel level sensors to any of the
general-purpose inputs. Be sure to configure the firmware to recognize the capacitive fuel level
sensor on the fuel level input(s) you’ve chosen as described in the Fuel Level Configuration
section on page 6-13.
If you are installing Dynon’s Capacitance-to-Voltage Converter (most commonly used with the
capacitive plates in some RVs), please read Capacitance-to-Voltage Converter Installation on
page 9-35.
