Has anyone else used the Mopeka Bluetooth propane tank detectors? I've had them for a couple of months now and, while I don't now how precise their fill measurements are, they are doing a great job keeping me up-to-date an general usage. I keep one tank wiht very little propane and another I refill when it's empty (that way when I run out I always have a little backup without ever carrying two full tanks.

These use sonar and attach to the bottom of the the tank. They connect to a Bluetooth phone app. Set-up was pretty easy once I figured out what I was doing. I'm really happy wiht them.

I noticed the other day that Mopeka sells a similar device for water tanks and I am considering trying them. Please let me know if any if you have used them. I know folks on here say you can check fresh water fill by looking at the tank but on my 172 I can't figure out how one would do that because the tank is positioned up into the frame in a way that only the bottom is visible.

Anyway....it's fun to find a useful gadget that works.

Happy camping

I have three of the sensors. Two are attached to the tanks on our RPod and another to the tank in the truck bed. I have the panel for the two in the RPod and the app on the phone for the third. Accuracy is so-so. One day it will read the tanks as full, the next, as nearly empty. It is this lack of consistency in measurement that is frustrating. It seemed to be accurate at first, but overall, I would save the money and use the hot water method which is the most accurate after removing the tank and weighing it.

That being said, I also have two of the tanks with the guage so I can compare that with the Mopeka device. That is how I can make the comment about lack of accuracy/consistency in measurement. If I had known how inaccurate/inconsistent these sensors are, I would have saved the money.

I always just chalked it up to expansion and contraction of the liquid in the tanks. The Mopeka sensor operates by sonar, bounding sound waves off the liquid/vacuum interphase. My last sensor even came with gel like they use for sonograms, so maybe they figured out that the sound transmission was inconsistent and borrowed a page from the medical industry.
