The propane tank sits on the scale while it’s connected to your grill. It’s safer than other measuring methods because it works with closed tanks. And it can be kept outside, but it does need to be covered to protect it from rain and snow.
Keep track of the level on the digital display or through the app, which also has programmable cooking timer. The system is easy to integrate with your grill, and is a great way to make sure you never get caught with an empty tank.
