These Mopeka sensors work well and add a new level of convenience to monitoring propane levels. There was a period where this new Universal model was incompatible with the Victron Cerbo GX, but I am happy to report that this situation has been resolved. I can check the levels using the Mopeka app; and they now show up on the Cerbo as well. How far we've come from having to pop open the propane compartment and look at a gauge that may or may not be accurate.
A few installation tips:
— The process is very easy; however, you will be asked to position the sensor so its position appears inside a little circle that shows in the Mopeka app. I've never seen anyone successfully do this, either in person or in a YouTube video. It seems like the best one can expect is for the position indicator to be touching the little circle. Don't sweat this. Everything will still work. I ended up using a ruler to position the sensor.
— My least favorite thing about this product is the fact that there is nothing to hold it in the spot that you've so carefully measured out. The sensor has pretty powerful magnets to hold it to the tank, but once you lube it up with dielectric grease it will slide around on the tank's surface. Annoying. Mopeka does offer a collar that can be stuck on the bottom of your LPG tank with 3M VHB tape to lock the sensor into position. This is what I have done. (The company makes two different collars. Make sure you get the one for LPG tanks.)
— These sensors come with three little aluminum spacers designed to clip to the bottom of your tank in order to provide extra clearance. You may or may not need them. I did. These spacers can come loose. I would suggest using an adhesive/sealant to lock them in place. Also, these will definitely scratch up whatever the tank is sitting on.
— For those needing spacers but not wanting to scratch up their propane tank compartment, Mopeka offers the "Halo", a plastic ring that goes on the bottom of your tank. These will also need to be attached with an adhesive/sealant if you want them to stay on. Unfortunately, these Halos offer less additional clearance compared to the free aluminum spacers. If you choose to use the collar I mentioned earlier, the Halos probably won't work for you. They didn't for me. Seems like this is something that Mopeka should have been able to anticipate.
— Keep in mind that these spacers protect your Pro Check sensor when it's sitting on a flat surface. The teenage kid filling your tank can still set the tank down on an uneven surface or a rock and crush it. And if this kid drags the tank on the ground and knocks off one of the spacers, the sensor could get damaged on a flat surface. Bottom line: pay attention when someone else is handling your LPG tank.
I'm tempted to deduct a star due to the incompatibility between the Mopeka Halos and the collars but this is a review of the sensor itself, so I won't. These sensors are game changers. I love them and I recommend these as the best solution for anyone with a propane tank they want to monitor. Five stars.
