Pro Check Universal

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.

I am impressed with how well these things work. Far better than a pressure gauge. Even if they are only five percent accurate, they are worlds better than pressure. The setup is easy except for having to press the button to start syncing and trying to get it leveled according to the app. It takes a few tries. I was pleasantly surprised to see that these automatically connected to my Victron Cerbo GX, so I don’t even have to use the app.

One of my original tombstone shaped sensors finally died during our winter trip. I went online to order a replacment and found these newer sensors. So far the difference is night and day. They appear to read more quickly, are much more reliable, and require less energy than the older ones. Very happy with the purchase.

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 is an awesome product. I installed the sensor as soon as I got it. Easy to install and download the app. I ended up buying the bottom ring extender just to make sure I wouldn’t smash the sensor. I would recommend.

The principle behind the sensors function is simple. Or, at least it should be if the sensor is thoughtfully designed. I have two 100# (25 gallon) tanks feeding multiple devices on my property. Tanks are mounted in an enclosure with a level base made of concrete pavers. A nice level, unchanging surface. The tanks only move when they need to be serviced or filled. Should be an ideal setup. Like most all propane tanks, the bottom of the tanks are rounded. There is no support ring - instead, the tanks sit on wheels and a metal support when vertical. The tanks CAN be used horizontally, but we don't. There is abundant clearance for the sensor. Due to the typical rounded tank, the sensor does not sit perfectly flat. A thoughtful design could fix that (3 magnets with some protrusion, for example), but that little detail was lost on whomever designed this product. Like some others have commented, we found one sensor seemed to work, at least at first. When a second sensor was activated on the adjacent tank, it went tilt. Two tanks, both newly filled today: One reads full (most of the time) and the other read 32% full when the tank was empty, then totally empty once it was completely full. Huh?! 9 hours dealing with this, I contacted Mopeka Customer Service. The email response said, among other irrelevant things, that they "need to hire more sales and support staff." I don't want to hear excuses why they can't support their product, or won't. Returning the product. It just does not work as advertised, nor is it properly designed to do so.

Mounted on two RV 30lb propane tanks. They work great and give peace of mind about your propane levels when camping.

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.

This is a small but very useful bit of kit. Isn't it everyone's nightmare guessing how much gas you have left. Not anymore once set up on your bottle it links to your phone via Bluetooth and tells you the exact percentage left. Has made a trips alot less stressful.

Funktioniert auch mit Victron Panel. Super zufrieden

Realmente es muy fácil de instalar. Instalé el sensor en un tanque horizontal de 110L ubicado en una azotea en una casa de dos niveles. Solo hay que tener cuidado de centrar el sensor en la parte baja del tanque, el nivelador de la app es muy útil para que quede bien. Seleccioné el tipo de cilindro "120L Horizontal" para que el sensor funcionara y calculara correctamente el volumen del tanque (-2L Error, respecto al volumen real). El estar expuesto a la intemperie a no ha modificado el funcionamiento del sensor. La intensidad de la señal es buena, 3 de 4 rayas de la intensidad de la señal, leyendo desde planta baja. El único inconveniente es que la app tarda en sincronizarse con el sensor cada vez que reviso el nivel en mi celular, es probable que sea mi celular el chafa y el origen del retraso, pero en la tablet es más rápido.

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
