Technically, the fuel computer system in the FlightDEK-D180 operates from measurement of fuel FLOW, not fuel LEVEL. X amount of fuel onboard - fuel flow = remaining fuel onboard or distance, etc.
If the "belite" fuel level sensors output a 0-5V DC voltage proportional to the fuel level, or a change in resistance proportional to the fuel level, then yes, they will work with a FlightDEK-D180.
Will my D180 fuel computer work with the belite fuel level sensors.
