Appendix F: C o-Volt rter Installation
Dynon Avionics’ capacitance-to-voltage converter is
suitable for gener
it
level sen . It acce a fem
outputs a dc voltage si be read by the
FlightDEK-D180. It requires 10 Vdc to 15 Vdc for power
and draws minimal current. We recommend that you
connect the capacitance-to-voltage converter to the EMS
for power as shown in the table below, but it will also
work properly when connected directly to standard 12
volt aircraft power. If your aircraft runs on 28 volt power, you
voltage converter to the EMS for its power source. Voltage inputs higher than 15 volts will
damage the device.
GENERAL INSTALLATION RECOMMENDATIONS
Connect the female BNC to the
male BNC provided with your
capacitive fuel level sensor.
Connect the wires as shown in the
table to your FlightDEK-D180. If
you need to extend the wire beyond
the supplied length, we recommend
avionics grade 22 AWG wire with
Tefzel® type insulation.

You must configure the fuel level sensor type on your FlightDEK-D180 to capacitive sender
before calibrating this product. Re
Once the system is calibrated for a certain type fuel, only that fuel may be used and the
aircraft should be placarded for such. For example, ethanol has a dielectric constant much
different than 100LL or Auto Fuel. If calibrated for 100LL, then by using Auto 10%
Ethanol in the tanks the indications could be off by 50%.
