We also use the Mopeka sensors. They are accurate enough for our use. Since we camp in the mountains a lot of the time, propane usage is very erratic. We keep one tank open and watch our Mopeka. When it gets to 20% during daylight hours, I open the second tank. Then, I schedule a trip to town. The Mopeka sensor sends me a message at the percentage I set for notification. No more 3 am trips to flip the tanks.
