Mopeka Tank Check LED Gauge Display - New Silver Reprogrammable Model - Mounts in Dash/Control Cabinet to Provide Wireless Indicator for RV Propane Tank Levels

After 3 years of guessing how much propane I had and removing and taking tanks to be filled partially full I bought this LED indicator along with the universal magnetic sensors (on separate orders). First I downloaded the app, then I installed the sensors and sync'd the app and the indicator. Super easy, both worked perfectly and read within seconds, IMO they both match (see the pics). The price was very reasonable and the order was delivered quickly (just in time for an upcoming trip). I mounted the indicator using command strips. I just to be sure everything was accurate I swapped the sensors and had the same results. Be sure you read the instructions and you should not have any issues. The only thing of concern is the sensors small magnets, time will tell if they hold up and don't slip.

I bought this gauge along with the sensors as a package but the sensors came separately several days sooner. So I installed the sensors with the phone app but when this gauge came I had to pull out the tanks again to pair them with this gauge. So wait until you receive everything as it will make it easier.

Nice to see the amount of propane in the tanks from inside

LCD Connects to the sensor with ease. Mobile phone app seems to be more accurate. I had to cut the diameter measurement in half for a arbitrary horizontal 21 gallon rectangular water tank to match the mobile app. The mobile app settings show tank height whereas the LCD settings only show tank diameter. Not sure how the math works out in the programming for the tank volume. My tank height is 13" and by entering 6.5" on the diameter allowed it to match the tank volume showing on the mobile phone app. I wonder if there was away to update the firmware on the LCD display.

works as it should. Very handy. I highly recommend this system if you have an rv with propane tanks

Got this for free with a couple sensors I bought. It's basically trash. Never got it to sync correctly and ended up just throwing it away. I got the Wi-Fi bridge and the app on my phone to check my tanks.

The unit is accurate through the App on your phone but the LED display is extremely inaccurate. In the pictures the App shows that I have 38% remaining propane in the tank. That is correct. The LED device shows that I have 3 out of4 light remaining or 75%. The LED device is misleading and inaccurate.UPDATE I contacted Mopeka and they gave me a calibration procedure that did not come in the initial packaging. Once I did this procedure the unit performance improved. The App is still far better than the LED device and is my recommendation.

I bought two Mopeka Pro Check Propane Sensors from Amazon on 18 April 2023. I used these sensors to provide propane levels in the two 30-pound propane tanks mounted on either side of my fifth wheel RV. The two sensors provided propane level information wirelessly to the (free) Mopeka Tank Check app via Bluetooth. This arrangement worked very well.I bought a new fifth wheel RV in 2024 and moved the Mopeka propane tank sensors from the “old” propane tanks to the “new” propane tanks (both sets were 30-pound tanks).On 17 December 2024, I bought a Mopeka LCD Display Gauge from Amazon, and I installed it a couple of days ago. The Mopeka Tank Check app still works fine; however, I can now push a button on the wireless LCD display mounted inside the RV and get an immediate read-out of the propane level by tank (in terms of percent full and gallons remaining). Mounting the LCD bracket was a no-brainer (two very small screws). The display is held in place on the mounting bracket via magnets. Again, another good, functional wireless design.I am quite pleased with these Mopeka products. They take the guess work out of trying to determine propane levels, which is obviously important if you use propane for cabin heat, cooking, and/or heating shower water.
