Mopeka Wireless Propane Tank Level Sensors

Ray

In this video, I continue my 2020/2021 winter RVing preparations with installations of an air conditioner cold-weather cover and Mopeka wireless LP gas level indicator for my two 30 lb LP Gas (propane) cylinders.

The AC cover will help protect the unit from the freezing weather and reduce cold drafts inside the RV. With the wireless propane tank level meter, I should get a more convenient and accurate idea of when I need to head out for a refill.

The vinyl AC cover simply fits over the rooftop plastic cover and has a drawstring at the bottom to hold it in place. I also decided to layer the inside vent cover with Reflectix foil for added insulation against the cold.

The Mopeka transmitter attaches magnetically to the bottom of the propane cylinders and has two methods of attaining the level readings. One, a physical LED panel that I mounted next to my battery monitor or two a smartphone app. The smartphone app is much more accurate by displaying level readings as a percentage full.

Nice video Ray.

I've used my Mopeka level indicators for a couple of years. The first set of batteries lasted about a year, the second set are still going.

Until recently I haven't had a problems with the aluminum feet. Last fill I lost one during transport.

Occasionally I forget to remove the sensors when I pull the tank to get it filled. If you ever leave them to get filled, they come off pretty easy and could get lost. I put my name and phone number on mine.

Good product, I think you'll appreciate the convenience and accuracy.

Thanks for the video Ray. I’ve used these for over 2 years now and love knowing how much propane is in the tanks. I have the ring instead of the clips to lift the tank and find those easy to use. The only issue I have had is lately after taking the tanks for a refill, it took a while to get the sensors working again. I saw they now provide the dielectric grease which I never had, so I tried spraying a little silicon lubricant on the rubber pad, and walla, they work like a charm now. I guess a good water proof lubricant is needed to keep the rubber pads in shape. Probably not on every fill up but whenever they may seem to need a little care.
Glad you did the unboxing.

Interesting, thanks for sharing that. Cheers, Ray

UPDATE Feb 6th, 2021 Sensor Failure
In this video, I give you an update on my Mopeka wireless tank level monitors. Recently one of the tank sensors failed and started eating batteries. It happened right after I had used the tank with my propane fire pit, and the tank became quite frosty on the bottom. I take apart the two sensors comparing the good and bad sensor’s battery input ohm readings and theorize as to what happened. I believe the excess cold and moisture caused the main microprocessor chip to become defective.

Interesting video. I was kicking around the idea of trying these. In your opinion would applying a conformal coating at the consumer level make any sense?

Have you contacted Mopeka and did they have any response?

Also the sensors are attached by just magnets correct? Does it seem like a secure enough bond to keep them in place if you hit a big pothole or bad washboard?

Makes sense to me. They use the stuff on auto and marine electronics all the time. I plan on trying this conformal coating https://www.amazon.ca/MG-Chemicals-422C-Conformal-Coating/dp/B085G42TGS
Mopeka is sending me a new sensor and I asked and they replied that that coating would be fine to use. The magnets are pretty strong but not sure about a rough road. When traveling I'll likely just pull the sensors off or could use tape on them. Or put a net under my tanks. :)

*Update* March 16th, 2021- Added Conformal Coating

In this video, I apply MG 442C conformal coating to my Mopeka sensor circuit boards to improve their weather resistance. After coating, I reassemble and put them to the test by running my Outland Fire Pit on a cool, moist morning. The cold, damp weather causes a layer of frost to form on the propane cylinder’s bottom. I hypothesize that this is what caused the failure of my sensor IC chip. This time the sensor kept working fine, so I’m hoping the conformal coating has solved the problem.

I have used the Mopeka sensors for two years with good results. I did have to replace one as it had the same issue as Ray did.

Thanks for the feedback. I'm hoping that my sensors hold up now as I do find them quite accurate and it's great to know the propane levels so easily.

I have used the Mopeka sensors for a few years now and I am happy with the response rate and tank level reading. I use them with my iPhone. I did have one that went through a battery very quickly and I asked Mopeka about it and they replaced it with no problem. Out standing customer support. I use the rubber ring for my tanks and it works better for me when taking for a refill and reinstalling the sensor. Those aluminum clips were very aggravating and hard to keep up with, the rubber ring is much better for me.
