We have been told not to trust fuel gauges. But if there were two fuel gauges using different technologies and they both indicated the same level, then could we trust that? If so, then a sight glass would not be needed.
The Dynon FlightDEK-D180 has inputs for two fuel sending units which can be setup for either resistive (float) or capacitance type sending units. Van's Aircraft sells a Capacitive to Voltage Converter that is compatible with the Dynon, Part Number = IE P-300C, Price = $45.00. See Dynon's website: http://www.dynonavionics.com/docs/news_cap_to_volt_shipping.html
Van's also sells a kit to make a probe for $60 (not designed for the RV-12). Or you can make your own with a 6" x 11" aluminum sheet insulated from and mounted 1/8" from the tank side. This guy made his own:http://74.125.47.132/search?q=cache:fbjbN8duasMJ:myweb.tiscali.co.uk/jbtrellis/Correspondence%2520on%2520cap%2520fuel%2520sender.doc+%22file+I%27ve+edited+down+from+a+series+of+communications+%22&cd=1&hl=en&ct=clnk&gl=us&client=firefox-a
There are probably commercially available capacitance probes that output 1 - 5 volts that the Dynon requires. Their advantage is being top mounted and ready made.
Anyone have comments or suggestions?
