LPG Meter sensor can be used in tanks such as RVs, heaters, grills, etc. The fill level in the fuel tank is measured periodically and sent wirelessly to the LPG-Meter software. The LPG-Meter sensor magnetically sticks to the bottom of your propane tank, so you know exactly when you're running low on propane!
