Mopeka Pro Check Bundle - 2 Pro Check Sensors and 1 LED Display - Wireless Propane Gauge for your Dual RV Tanks - Monitor Propane Levels Inside your RV on the LED Display or the Free Tank Check App

Excellent for knowing exactly how much propane is in your tanks. No more jiggling the tank to guess how much propane is left. These are very accurate. Installation a breeze. I recommend getting the hard rubber halo rings to go with them. Lifts your tank up just enough and helps steady the tanks in your holder.

Easy to install (literally magnets to the bottom of your tank), connecting to my phone was seamless, and it feels incredibly accurate. You do need to zero the unit out, but the included instructions and app make that easy.I added 2 more to my camper tanks. Would purchase again. Might look at the option that allows these to connect to the internet instead of just relying on bluetooth and being next to them to work... but they exceeded my expectations and I'm happy with the purchase.

These installed very easily and they are great for monitoring the level of your tanks

Couldn’t get to connect to the device it came with but it is easily checked on the app so still very helpful

Good addition to any camper! Works well!

Easy to set up and very accurate readings

My wife always worried that we’d run out of propane while on a trip. The Mopeka Pro Check Bundle was exactly what I needed to erase her concern. The sensors were easy to install, apparently are pretty accurate, and having the Bluetooth display on the camper wall as well as the app on my phone makes checking levels a breeze. I liked the kit so much, I bought two more sensors to use on the tanks of our home outdoor BBQ grill and pizza oven. Now I also don’t worry about starting to cook and running out of gas. I highly recommend this product.

I love this because my tanks are outside of the RV and I have no way of knowing what levels my propane is at. Usually, when the stove won't light or the heat doesn't heat, do I know I'm out of propane, and having to go outside in the freezing temps to switch tanks is not my idea of fun.I ordered these and now I can tell what the tank levels are from inside the RV and can better manage when to switch or refill tanks without having to wait until they run out which is usually at the most inconvenient time. This enables me to have control and visuals of what the tank status is. It is well worth the money. I will say that one of the sensors that came in the original package did not work, but the customer service was great and the immediately replaced it.
