Review on 🔍 Optimized for SEO: AP Products 024-1002 Gas Level Indicator for Propane Tanks by Gabe Evans

I had a very hard time getting it to work. Here's what I needed. Most of these are not mentioned in the instructions. If your tank has thick walls, you will need to scrape down to the bare metal where the sensor is installed. The metal should be fairly smooth. When removing paint with a Dremel or similar, you will need to sand out most of the scratches with sandpaper or a very fine file and then sandpaper. Do your best to create a flat spot the size of the sensor. A smoother contact area with the sensor seems to help the devices work a lot. Depending on the curvature of the bottom of your tank, one magnet or another may tend to be attracted to the tank and strain the sensor so it doesn't fully touch it. Tank. If this is the case, cover the magnets with tape or something similar so the sensor stays flat on the tank and the two magnets are just above the adjacent surface of the tank. Don't use too much tape as the magnets should hold the rubber sensor firmly to the tank. It may take 20 minutes or more for the rubber sensor to snap into place on the tank. Every time I moved mine, it took another 20 minutes or more for the magnets to "mold" the sensor against the tank. Appendix. Changing the tank and scale settings (from 30lbs to 40lbs and percent to inches) and then back to what I wanted also seemed to help (as well as logging out and back into the app after each change). Although it may have just given my sensors time to settle down. If all else fails and you are sure the rubber sensor is firmly and evenly attached to the tank, allow 24 hours to sit on the surface of the tank. With one of mine I got a full 3 star quality the day after the installation. I tried some silicone between the sensor and the reservoir, thinking it would help fill in the gaps between the sensor's rubber surface and the reservoir surface, but it seems to have survived. Blocks don't work at all. If you need to make the above adjustments, keep an eye on the "Quality" indicator (three vertical stars). Until you get at least one star, you'll only get erroneous readings. Since the sensor has been sitting for more than 20 minutes or more (perhaps a lot longer), you should get extra stars. If not, follow the steps above. And if everything looks good, give the sensor more time to adjust, maybe 24 hours. My devices came with aluminum tank feet but I haven't used them. Instead, I epoxyed four 2" x 3" x 0.5" pieces of wood to the metal shelf to hold the metal rings at the bottom of my tanks securely above the shelf. I missed an inch of wood protruding into the ring. Eventually one of my tank's metal support rings was welded a half" or more off center. Centering the sensor in this ring didn't work very well. Things got better once I saw this and moved it to where the actual center of the bottom of the tank is. "As Mopeka pointed out, there's usually some sort of flat spot. Mine was small but useful. Both sensors work great. Can't comment on durability yet, but being able to see the tank percentage on the app is definitely better than the pouring hot water on the tanks in the last few days when they are almost empty.
