Review on AP Products 1212 13 024 1000 Monitor by Bobby Posner

Initially, the readings were somewhat accurate. I haven't moved my trailer in a few weeks and the instructions say accurate readings are dependent on propane buildup. However, over time, readings became inaccurate and inconsistent. The sensors are difficult to test because they are attached to the bottom of the tank. To ensure they are installed correctly, the tanks must be removed. Each time I did this, I found that the sensors were attached and positioned correctly. Installed aluminum spacers as instructed. The devices just didn't work. I really hoped they would, but I couldn't get the Android app to pair with the sensors either. The monitor connected easily, but again the readings changed even though no gas was used, so the actual readings stayed the same. A tank was about half full but always showed as empty. The other tank was completely full and was initially full, later a quarter full and finally empty despite being full. I cannot recommend this product at all. It was a miserable and arduous failure.
