Review on GrillPro 00030 Magnetic Gas Level Indicator: Effortlessly Monitor Your Propane Tank Levels by Andres Black

I don't see any indication of the propane level in the tank on this gauge. While using a propane tank running in the shade the gauge got stuck in a few different places on the tank (actually I bought 4 of these and put 3 in different places on the tank to cover the whole tank so don't forget to take somewhere a spirit level) and for tanks that were later found to be about half full I could never see any trace of the level. Ambient temperature was about 70 F. I have used these gauges on both the grill tank when I was cooking steaks and the van tanks when the propane oven was running. The sensors were at where the propane level should have been and in fact still covered the entire tank. I will say that the longest I have run propane was about 15 minutes. I suspect if I had let it run much longer the sensor would have been able to detect the level. At the moment there seem to be 2 viable options: Scale works based on tank weight and see-through tanks (yes, if you look for that you'll find that there are DOT approved fiberglass tanks that don't cheaply let you see the propane level in the tank about $70 for 5 gallon and $120 for 7.5 gallon tanks). Unfortunately these magnetic temperature sensors don't work and pressure sensors aren't supposed to work and there are also many complaints about leaking pressure sensors. Currently the only inexpensive solution is a spring gauge for propane tanks. I think the inventor of this gauge had a good idea, but where he or she went wrong was a) the magnet and b) the short length of the gauge. What will almost certainly work is take a long strip covering the entire length of the tank (in two sections: one above and one below the weld line. Actually 2 gauges for a tank) and glue it to the side of the tank with glue. Tank instead of magnet. I use something similar to measure temperatures in plastic fermenters when brewing beer; they are very cheap and work well. My guess is probably that the magnet has too much thermal mass and is probably conducting heat up and down the sensor. A very thin, cheap adhesive tape, such as B. a manometer, does not have this problem and absorbs the temperature change faster. Let's get back to the drawing board, folks.
