I apologize.
I did read the post. I know dial doesn't have the sensor in it. I thought that was already a given.
The sensor snaps into the goove on the top of the gauge
The gauge just lets you connect a sensor to the top that passes through to the magnet that is currently
running the tank level on the gauge.
This link shows the gauge and the sensor cable although the cable doesn't seem to be available anywhere.

I am aware that there are some devices and already made for this.
and even some propane companies use these types of monitors already.
So the sensor cables are out there and being used. Just need to find the cable.
It can't be that expensive. I hope
