Mopeka Pro Check Sensor - Wireless Propane Tank Magnetic Sensor Level Indicator - Propane Gas Tank Pressure Gauge Electronic for BBQ Grill - Remote Ready Propane, Butane and Fuel Level Gauge with App

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.

Just installed so I’ll update if anything negative happens, but so far, it seems accurate. During a recent snow storm that blanketed our area in ice, we got down to about 10% and had to call out our propane company. A small path had to be cleared to get to the tank and with the sleet coming down try and get a clear photo. Needless to say, it was cold! I looked to see if there was a wireless reader, maybe something inline with the manual dial, that could be used to look at levels from the comfort of a dry and warm room, and found this. I got it in 2 days before this review and made sure I knew what needed to be done for the install and it was easy. The bottom of my tank was dirty so I used cleaning wipes to get the area clean enough to install. You have to liberally apply the dielectric grease on the sensor and then place it. That’s it! As you can see from the photos, it is about a 3” circle. Before placing it how the sensor is read, but not connected yet. The manual dial showing just above 60% and then the app showing the same. It is working on a 500 gallon tank and I anticipate it’ll be safe, as it’s only magnets on the outside, and barring the battery being outside in extreme temps, I anticipate it’ll last quite a while.

This was easy to set-up using the app and has good range using Bluetooth. I tried it on 3 different 20lb cylinders of known quantity of LPG and it read them all accurately. It sticks to the bottom fairly well, but they are rounded so it takes a few seconds to center the sensor. For my use they adhere well enough. I would not be so liberal with the grease, it only needs a dab on the sensor. This should help with movement once centered. As for replacement Mopeka grease you can buy some here on Amazon, or any silicone dielectric grease works perfect. It is the same. I am overall very pleased with this device. It is not cheap, but it's accurate and does the job well. I wasted a lot of money on inaccurate inline gauges and a scale device. The scale does work, but requires disconnection and lifting of the cylinder, and can't give you a real-time reading. Now I know at a glance where I stand gas wise.

I have tried every sensor this company has and none of them work. The iphone app does not read anything but "Empty." My tanks were just filled at the hardware store so I know they are full. I also have a small reader with lights and it also read "empty." I have used dielectric grease and have moved the sensors n the bottom of the tank around to different locations in the center of the tank bottom. All readings: "Empty." So as far as I am concerned these do not work. I have 2 30 gal tanks on my RV. UPDATE: and speaking with the representatives from the company, who were very conscientious and honest, I found that the problem was mine. The tanks that I have have a thick paint coating, which is inhibiting the signal. So the sensors are fine. And they do their job. I had to alter the paint coating on the bottom of my tank in order to get the sensors to work.

This setup is exceptional. It has been so wonderful to accurately monitor the propane tanks from inside. Installation and setup were easy. Please know the wall LED needs to be adjusted for tank capacity if not 20 lb. That wasn't in the enclosed directions, but you can find how to on the web. It is snowing hard outside and I am happy and warm inside watching the propane level knowing I won’t be surprised when it gets low. No more bringing out a scale or using inaccurate gauges on the tank in the cold weather. Thanks Mopeka for a great product!

These Mopeka sensors work beautifully on the 20 lb tanks on my RV. I initially only purchased one, but after using it I got a second one for the other tank. Installation is simple. They are held in place with magnets. You just have to apply the provided gel to the sensor. The app assists you with level placement of the sensor. I also purchased rubber rings for the base of each tank so I can't comment on the provided metal spacers. I didn't use them. Bluetooth range is very good with the rings installed - 30ish feet. If you're installing two sensors, name your tanks and your Mopeka sensors so you can keep track of them at refill time.

Muy difícil de usar

J'ai acheté ce produit et l'ai aussitôt installé et téléchargé l'application. Fonctionnement immédiat et précis. Je pense que c'est un des seuls produits fiables pour mesurer la gaz restant dans une bouteille. Je recommande chaudement

Amazing piece of kit, as soon as we put it on the bottom of the tank and linked to the app we got a reading that we had 30% of gas left in the bottle which there are no other devices that are sold that do this

Funktioniert auch mit Victron Panel. Super zufrieden
