RV Propane Sensor Accuracy Test | Mopeka Pro vs Original | Wireless Bluetooth LPG Monitor

We travel full time in our RV and we've been using the original Mopeka RV Propane Sensor for the past 3 1/2 years. In today's video, we'll match the Mopeka Pro Sensor up against the Original Mopeka Sensor to find out just how accurate they both are and to also find out if the Pro is worth the upgrade. We test the bluetooth monitor accuracy by weighing the tank and calculating to find the weight based percentage then comparing the results to the sensor readings. If you like gadgets for your RV, you're gonna love these propane gauges that will help you to easily keep track of your propane levels via the Mopeka bluetooth phone app.

A well put together and very detailed presentation! Thank you for putting in the work for us!

[mikekennedy]

Thanks for the great tutorial. We have two 20 lb tanks and use one at a time keeping one full. We travel in summer months and spring, I will be looking at one now. Thanks again

[jonminer]

Thanks for your help. I will forward your page to my sister who seems to have trouble with her propane tanks. Thanks for sharing! Stay Healthy!

[audreywinston]

Great video Eddie! Thanks for doing all the testing and research on these sensors. We’ll definitely be buying a few to help keep track of our propane use.

[mrgcav]

An excellent job worthy of Project Farm quality.

[timhartman]

Well done! You earned a new subscriber. Looking forward to watching more of your videos.

I have a horizontal tank, one tank, 16 gallons, which model do I need? regards.
Great video

You may be glossing over an important detail regarding the inches vs percentage measurements. The surface of the liquid propane is a squared off cylinder. The bottom is not! So it will always be taller in inches than it would be as a percentage. You're expecting it to be a linear relationship, but it isn't.

Holy crap that is a good review- Thanks

[scottwhitesell]

Very helpful and informative. Thanks for the education :)

I have the original Mopeka sensors and they have worked pretty good for the most part. I have had to replace the batteries every 5-6 months and I recently had a different issue. We're snowbirds and staying at a resort in a town where they charge for propane by the fill rather than how much is being put in a tank. So if my 30 pound tank has 5 gallons of propane in it and I want to top it off, it costs the same as if my tank is completely empty. So I was watching my propane use daily and saw where it got down to 2% left according to the app. The propane actually lasted another 24 hours before it was really empty and our Absorption refrigerator warned us that the propane wasn't available. I switched tanks and turned off the empty tank. Each of the past several days, the app has gone crazy with reading the empty tank. Each time I check, instead of saying the tank was empty, it has said it's 54% full, it's 10% full, it's empty, it's 7% full, it's 25% full etc. It is always showing something different. The battery level is full and I just changed them a few weeks ago. What do you think the issue is with that?

Great Video, thanks & greetings from Germany

I have no problem with the old version. So far it's been a year on my battery. Very accurate. I think you beat up the old version for no real reason. Sounds like promotion to spend more money on the pro. They have rubber bottom insert you can get instead of the clips on Amazon and they keep any depri to buildup under the tank. I have checked my propane right thru the winter with no problem. So if your on a budget like most people are the original one works flalisly. I love it. You probably should change the battery once a year like a smoke alarm anyway. So every season you have a fresh battery.I change mine anyway no matter what the app says. What's the cost of a battery anyway for piece of mine. Isn't the reason you bought the monitor anyway?

The original is good enough to just tell you, you better change soon. That is good enough to me. Great product.

[bretg]

Strange question: how much does your data points and results change, if you use 23.0 lbs TW vs the 23.1 lbs that you used?

[JeffinTD]

Nice review. As I have the originals that are working fine, I’ll just deal with the battery changes. If I were to buy again, though, better battery life would make the pro worth it imho.

Other than that, their spacers weren’t very durable. Cut some aluminum that attach via a screw using existing holes on the tank base, and that works a lot better.

[ksti]

Great review! Has the accuracy of these sensors gotten any better for you? Ideally (for the situation I’d like to use these in), we’d like to be able to measure usage per day. Unfortunately, that data won’t be very reliable if it varies by up to 5%.

[Whawk]

Hi ed awesome review thinking on buying this device does this read a 5kg tank ?

[matteopastore]

Good evening. So I understand that the PRO version is better right? A thousand thanks.
