This is a cross-post with a topic I started in a different forum, but since it's sort of bridges that gap between Electrical and "LP Gas, Piping, Tanks & Regulators" topics I thought I'd post here too and let the moderators move or delete it if it's not appropriately categorized...
We're using the SeeLevel 2 Tank Monitoring system (
Amazon.com: See LeveL Tank Monitor 709: Automotive) which has the ability to display the remaining level of propane in percent. Our Excella has 2 x 40lb propane tanks connected by a regulator which supplies fuel to all the gas-operated things in the camper.
With all that being said, my question is this: what do I need to be able to monitor the propane tank levels using the SeeLevel 2 panel? Is there supposed to be a sensor on each propane tank? Or is there supposed to be a sensor on the regulator to report the percent full? I see neither in my current setup, so I'll need to buy something to make this work, just not sure what.
1. Do I need something like this Manchester Sender Unit?

2. Or maybe I need a sensor built into the regulator; something like this?
Propane Regulator Valves on Sale - PPL Motor Homes. I don't think this exact unit would work for my application since the "sensor" they mention sounds like it's just a light on top of the device itself.
Any advice, or pictures of your setup (with remote level monitoring) would be appreciated, thank you!
