Fuel Sender Issue

[RickT]

I have a Dual Screen D700 system. I have been trying for moths to get my Princeton fuel sender to talk to my Dynon. I have called Dynon and they cannot help , referred me to Princeton. I have called Princeton and sent back my sender and received a replacement. Still does not recognized fuel, will not calibrate. I am installing this in a Sonex with the AeroVee engine. Does anybody have any recommendations or can you tell me what simple fuel gage I can buy and install? I am wanting to get my newly completed plane in the air and am ready to fly with fuel gage! So frustrated.

From my understanding, with some models of the princeton probes you need to first calibrate the probe so that it registers a voltage change, but I'm not certain about that. Fundamentally, though, SkyView is recording a voltage change that the probe is outputting. So if that's not changing, that's a problem downstream of SkyView. First, though, what SkyView pin do you have it connected to? Only pins 8, 22, 23, and 31 on the D37 connector will work with active voltage output probes like the Princetons.

There are special single point Princeton probes that work well with Skyview. See this discussion:
