This is what is not working on my valve.... it stays Green when the tanks are full or empty. Use (1) at a time.

Usually in the mornings I can see a sweat line on the tanks showing where the propane levels is at...

I too only run one at a time... When one runs out of propane and switches over then I go fill the empty one...

I got my OFF-ROAD POPUP trailer in early 2009 so I guess my two tanks on that trailer will need to be inspected and recertified this year... I think there is a ten year time span here for the propane tanks... I guess they are probably already over the date being a 2008 model... I have been sitting at home here for past couple of years after my battery bank finally failed on me...

I've been using your method for years, never had a problem.

Mopeka. On my iPone with their app.

I only use one at a time. Once I had both valves open and the second tank leaked empty and then I was in deep dodo with the DW.

Same only with an Android.

My Airstream that I stupidly let my wife talk me into selling used to have LP tank quantity on the little status panel, pretty darn acurate too.

Now I use the thump method, and always use 1 tank at a time. The Airstream used to auto select, sigh. The Jayco does auto nothing.

Ya gotta luv it.

The picture you posted shows the tank on the left as being empty (assuming the valve is open). If you switch the dial to point to the other tank it should turn green (assuming it has propane in it. The switch will automatically transfer to the tank that has propane in it if one tank runs out but the dial will not move. You must turn it manually to the full tank for the gauge to turn green again. Then disconnect the empty tank and go fill it up.

If I need to check the level of a tank I will disconnect it and shake the tank. You can tell, roughly, what is left. Getting a cheap luggage scale is a good idea though and you can weigh the tank.

I also leave both tank valves open and always use the tank on the right. I check the auto switch every couple of days and if it has switched over (turned red) I know my right tank is empty and that I need to fill it. I will then put the full tank on the left side and continue to use the partially empty tank on the right side. This way I always know that I have at least one full tank.

I used to only open one valve until I had to get up in the middle of a very cold night and open the other valve. Don't want to do that again.

Hope that helps.
Cheers

This is what I used before I added the SeaLevel system with propane sender, it works well but seemed to eat batteries for me.

Me, I leave both on all the time and check the switch-over indicator from time to time.

Keep doing that.....and you are going to be really pissed when both run out!

I use the Dometic LP Gas checker...very easy and I find it to be pretty accurate. Also using one tank at a time so they are never both empty.

There is a gauge you can get on amazon. Unscrew the line from the tank and screw the gauge in. Takes about a minute.

You take the tanks only. Many places don't have the space to accomodate a trailer at their fill stations unless they fill motorhomes with built intanks.

Mopeka tank check, two sensors on the bottom of each tank, with the app, you check it on your phone. I paid about $75 for the two sensors on Amazon. Or you can get the tank gauges that screw on for about $12 but Mopeka tank check so much easier and more accurate.

I use Dometic LPGC10 LP Gas Checker. It is more expensive than I think it should be, but does seem to be accurate.

I use the following equipment on my 2 x 40 lb tanks in my fifth wheel. Work great! Use app for iphone or similar connecting through bluetooth. (Tank Check) The magnets are strong and have been trouble free for over a year so far.

[QUOTE]I use the good old fashioned method of pouring a little boiling water over the side of the tank. Pour it, and immediately run your finger down the side of the of the tank. Warm where there's no propane, and cool where there is.[QUOTE]


I used this technique this morning, but instead of my finger I used an infrared temperature gun. The liquid interface in the tank was immediately obvious. Thanks for the suggestion!


I also marked each of the two tanks with a Wet Erase marker so I can monitor the LP usage.

This is our first year with twin 30# tanks. Fill em both, open one side, and when it runs out, flip the lever over to the other. Keep track of how many days it took for the one tank to run out, and continue to keep track so you can figure out the avg. amount of time.

One 30# tank lasted an avg. of about 15 days running straight, so we knew that it would be empty around then. If it was cold, we would flip the lever during the day when we knew it was getting close to running out. Within the next several days, we would remove the empty tank and fill it, and repeat the process.

Pros: no cost, and usually no worries. Our indicator was when the refrigerator light changed from green to red when the propane ran out.

Cons: once in awhile we would get the midnight empty tank indicator, and if it was cold, I would brave the cold and flip the lever.

We purchased 2 gauges from Camping world when they were on sale. They screw into the tank before you attach the hose(s) Camco also sells these type of gauges as well.

How do you know if you are low in LP gas.?
I have attached a picture of what my setup looks like.

Thanks in advance for any answers.

You don't have an automatic propane changeover valve on your trailer? That is the biggest advantage to leaving BOTH tanks turned on because when one runs empty it will automatically switch over to the full tank. Then you can manually switch the lever to the full tank and the indicator will go from red to green...or clear in some cases. I never get out of a warm bed to switch my propane tanks.
