The LPG Tank Check is able to accommodate variety of LP Tanks and provide you with up to date levels. Tank Check’s unique Sensors accurately measure your Tanks LP level and communicate that information to you via the optional Monitor or through the use of most any device equipped with BlueTooth. The Sensor’s Blue Tooth communications range enables remote monitoring up to 50’ away, depending upon obstructions such as walls and other material.

No more guessing at tank levels!Are these sensors strictly necessary? No, of course not! There are other, cheaper, (free) ways to check your tank level. You can just pick up the tank and see how heavy it is. You can pour a cup of warm water down the side of the tank & see a line where the liquid level is. You can buy a gauge that attaches to the valve at the top (don't do this, they are very inaccurate). I have even pointed an infrared thermometer at the tank - the area of the tanks with liquid will always be a different temperature than where the tank is empty>That said, my wife has this weird anxiety about running out of propane. Our trailer has two 30lb bottles and an auto switching regulator. We also have a pretty small travel trailer. Even during the winter when we are running the furnace, I could probably go 45 days on the two tanks.Every evening before bed, and several times after I was long asleep, she would have a panic attack and make me go outside and pour a glass of warm water on the tank to verify that that furnace just turned off because the thermostat told it to, and not because we ran out of propane and we are about to freeze to death.Enter these tank sensors. Each is roughly the size and thickness of half a deck of playing cards. On one side there is a small rubber pad, about the size of a dime, and two strong magnets. to use them you simply lay your tank on its side for a moment, clean off any accumulated gunk off of the bottom, and stick it on with the magnets so that the rubber pad is as close to the center as you can get it.Each sensor has a green button on it. The first time you use them, you have to press the button 5 or 6 times in a row, very quickly, to take it out of shipping/battery saver mode. You only have to do that one time. When you download the accompanying app from the iOS App Store, or the Google Play store, the app will 'see' the sensors and give you a chance to configure and name them.In our case, I connected them one at a time so that I knew which tank was which. The app defaults to 20lb tanks, so I had to change it to match my 30lb ones, and I named the tanks "Driver Side" and "Passenger Side". Now, when my wife is worried about propane, she can just pick up her phone and see the exact levels.Note that the sensors are very picky about placement and about the tanks themselves being level. Before our most recent trip I had the truck and trailer parked out in front of the house, at the curb. With the passenger side tires in the gutter, the trailer was tilting very slightly to the passenger side. Parked like this, one of the tanks showed 6%, even though I had just had it filled. Once we were at the campsite and level, it correctly showed 100%.The sensors seem to work using something very much like sonar. By attaching to the bottom of the tank, they can emit a "ping" up through the liquid propane, which is reflected back by the surface of the liquid. The less liquid you have, the lower the surface is, the faster the ping makes it back to the sensor. it's actually super simple and has the potential to be very precise.Caveats:* These guys communicate via bluetooth. So you need to be within bluetooth range to get a reading.* Because the tanks are steel, they tend to kill the range, so the sensors come with a set of aluminum clips that you attach to the base ring on the tanks. They act as "feet" to raise the tank by 1/4 inch to improve reception. These things are incredibly flimsy. My kit came 8 of them for two tanks, and 3 broke while I was installing them. They do sell plastic rings that attach to the bottom of the tank which are supposed to be more durable, but they are $14 each and I can't bring myself to do that yet.* The sensors are only held on by magnets. If you regularly remove the tanks to take them to be refilled, you either need to handle them very carefully & not bang them around (and potentially lose a sensor), or remove the sensors and reinstall when you put the tank back on.* If you use those "tank exchange" services at the 7-11, you have to remember to grab your sensor and move it to the new tank.One of my sensors was defective out of the box. It read between 3% and 6% regardless of propane level, how level the trailer was, or if it was even attached to a tank. I did quite a bit of troubleshooting and testing before I contacted the manufacturer, just in case I was doing something wrong. I filled out the support form on their website and they responded via email within a couple of days. They asked for my mailing address, and sent me a new sensor, along with a prepaid shipping label to return the bad one. They also said that they would replace the aluminum spacers, but they didn't - so I am a little annoyed about that.All in all, would I buy them again? Yes, absolutely. They are easy to use once they are set up, they give my wife peace of mind, and if I'm honest, it makes me feel a little better too - being able to see that I have 37% remaining, as compared to lifting the tank up and thinking "That's still about half full...."I purchased these for the Rv propane tanks. we have two 30lb tanks in our fifth wheel. easy to install. You have a choice to use only the included monitor pad, or download the useful App. Out of the box the sensors are able to read 20Lb tanks. The App allows you to Change the setting to 30lb or 40lb tanks, the alarm threshold and notification frequency. these mount to the bottom of the tanks with magnets on the sensors, I also added additional security by using duct tape. they come with aluminum spacers to use if needed. using the phone I could get readings about 30ft away from the rv.We recently went on a 4000 mile trip. over some pretty bumpy interstate highways back home they appeared as secure as when I initially put them on.Overall a very good product that solves the problem of not knowing exactly how much LP gas you have left in the tanks. The installation is very easy, just follow the instructions. I was able to sync with the mobile app with no problem. I highly recommend purchasing the molded plastic rings that go around the base of the LP tank. They give you some extra height between the sensor and the mounting tray. I didn't want to mess with the clips that came with the kit because they will inevitably fall off.I had to knock one star off because many, if not all LP tanks, have a rounded bottom, but the sensor is flat. This results in a less than perfect magnetic attachment and lower quality signal. I am going to buy some small rare earth magnets at the hardware store and try use them as a shim to get a better contact with the tank. That might help signal quality.I recommend giving this product a try. It will give you some peace of mind about how much LP you have and whether it will get you through a night without going outside in the middle of the night to switch tanks.This was a very quick, simple, and straight forward install. My RV propane tanks are the 20 lb size, so didn't have to change the default to something different. I did some quick weight comparisons and see that their wireless display is not as accurate as the indication on the smart-phone app. Still, for a quick check, it works great and I use the app too. I did notice that the sensor refresh rate can be toggled between 3.5 seconds and 10.5 seconds. It seems that the longer refresh rate would extend its battery life, but I won't know for sure until it needs a battery change. I think that the 10.5 seconds is still too frequent for normal; and up to 1 minute (or even 5 minutes) would be more than sufficient... especially if that significantly extends the sensor's battery life.The package delivered only included one monitor, not two as pictured. Am I still waiting for another unit, or was the merchandise incorrectly advertised?10/13 update- after REALLY close evaluation, I noted the two monitors are stuck together. They are so thin it looks to be one unit. My apologies!I will find something better to raise tanks instead of aluminum spacers. They seem like they won’t stay on after installation. Sensor magnets could be stronger. They can move easily. I haven’t had to refill tanks yet, so here’s my biggest question. Which level do I trust? The one that comes with it, or the app? I’m leaning towards the app at this time. I truly won’t know, until I refill the tank.Product works goodI was very very doubtful!!! I almost didn’t order. But now I’m thankful I did. Use a pocket knife to scrape the paint on the bottom of the tanks they work amazing.
