Propane Tank Level

[Paprika]

Spacers are needed because otherwise the Mopeka tank sensor module is just a little too thick to let the tank sit level. The spacers that come with the Mopeka sensor (used to be plastic; now aluminum) are nearly useless, because they're apt to fall off and get lost whenever you move the tank (e.g., to get it filled).

The "Tank Halo" works much better. It stays on, and also protects both the tank's bottom ring and the tank tray on which it rests. I'd call this a mandatory purchase with the Mopeka system. Yes, it's annoying to have to spend another twenty five bucks, but the Mopeka sensors solve a long-standing problem, and work so well that to me at least they're worth every penny. I wish Airstream would make them standard.

Get the halo, I just did. The spacers are a pain but the sensors are great.

The OEM monitor works...'kind'a. 🥴

Other that that I use the stove...if it don't light I'm empty. 😂
I have two tanks so it would be hard to run both out without noticing that both are empty...plus those fancy gizmo's=a lot of LP.

BTW...I only fill an empty tank, never let them charge you according to tank size👎, before & after weight or gallons.

Master it, no worries ever.

For me it just depends on my propane usage. If we've been hooked up and using electric for most things I don't need to check very often. If not hooked up and more propane being used for hot water, cooking etc. I do it more frequently but I simply remove the cover and take the tank off and shake it. I have no monitors hooked up and this works every time for me.

Our 2009 Classic has propane level lights in the kitchen and a gage on the top of each bottle.

So I performed a little test last weekend to see how accurate the Mopeka system is using a scale to measure the weight of each tank.

Empty Steel 30 lb Tank = 24 lbs
Full Tank = 54 lbs

Tank 1 37.8 lbs = 46% Mopeka reading = 55%
Tank 2 40.2 lbs = 54% Mopeka reading = 48%

So accuracy was +/- 6 to 9 %

Anyone else surprised at the tank quality?

Just want to say thanks for this thread. I was up at 2:45AM switching tanks, and had to read what others use to check tank level. I keep one open, one closed.
It was definitely a pain, and hard to get back to sleep, but eventually bliss in the knowledge I have one full tank, and can get the other filled after my morning coffee.
This forum rocks.

I've been using the Mopeka system for a couple years and I'm very happy with it. I particularly like:

-- the sensors have a surprisingly LONG range. I can check tanks from the drivers seat--or even inside my house when the trailer is at home.

-- the smartphone app tells you when it last checked the tank level. Seeing "20 seconds ago" vs. not knowing the age of the reading can make a real difference if you're trying to squeak through a cold night on a low tank.

-- the magnets that hold the sensors to the tank are very strong: I take my tanks to tractor supply and back in my truck and the sensors stay put.

-- I like that I can monitor from my smartphone AND use the "on the wall" display inside the trailer simultaneously.

-- Setup was super simple and easy. Price seems very reasonable.

Yes, you need the spacers. Mopeka's used to be absolute junk and now they've upgraded them to be only slightly better. I went instead with the "Tank Tire" -- an extremely pricey but very effective device which gives the sensors room, makes it so I feel more comfortable setting the tanks down other places (like my picnic table at home), saves the paint on the tank racks (less maintenance!), and generally reduces the noisy "clang" of dealing with tanks.

For tank tires--or any other spacers for that matter--make sure you drill some weep holes in the bottom. Mine were collecting water and rusting the bottom ring of the tanks... but once I drilled a few weep holes problem was solved.

Here's the Mopeka version of the Tank Tire... quite a bit cheaper:

I hope that helps!

How often do you feel like you’re changing the monitor batteries? Seems like it would be annoying to pull out the LP tank to change the batteries?

I'v had the Mopeka sensors for a couple of years and have been "mostly" happy with them. Battery replacement is the biggest pain, but the batteries have generally outlasted the propane in the tank, so when I refill the tank, I pay attention to the battery level which is noted on your phone app. If the battery is low, then I change it when I'm filling the tank. I had one sensor go out after having them for over a year, contacted Mopeka and they sent me a new sensor at no charge. The original green rubber spacers were junk. The new aluminum ones have stayed on the bottom of my tank because I compressed the gap slightly before I put them on the bottom of the tank. They haven't fallen off and I've saved the expense of the rings that people are referring to.

You can a couple years worth of propane for the dollars you will spend for this gadget. You know when one tank is empty and can change to the other.


Save your money.

Our 'old school',(no batteries) gauges have always worked.
Both on the tanks and indoor monitor.

l use the Mopeka tank check. Just have to change the batteries every year. It works well and it helps me know when the tank is low enough to get it filled. We camp early in the Spring and later in the Fall, and in Wisconsin that means a tank goes empty faster when using the furnace in colder weather. So I monitor them. I also have 3 tanks just in case. So when camping in cold weather I try to stay ahead of the game a bit. We were camping in 30 degree weather for a week, and we really used up the LP.

Don't think I would be too concerned if I was camping in warmer weather all the time.

Also you can determine size of tank monitored.

It's actually not that hard. Lift off the cover and just tip the tank over a bit. Simple.

[Brentone]

I for one (and seemingly I alone) have had no luck with the Mopeka system. Both on new and the original tanks, I get irregular readings all over the place on the app and constant "low level" notifications on tanks that are full. I have installed, reinstalled, added more of their vaseline goop/less of the goop, moved sensors, adjusted... you get the idea.
Seems like a great idea with inconsistent accuracy.

YMMV

[Tater]

We've had ours for a month. What we ordered had the monitor as part of the deal. So far it seems to be accurate. It was cold in March when we started so we went through a couple of tanks a month for a while. We are glad to have a monitor.
