Using a combination of a WiFi-enabled scale set beneath your tank and a smartphone app, the system is able to provide real-time measurements of the fuel level inside, calculate your average grills per tank, and even shoot an alert when it's running low, so you can hit the gas station for a refill well before you try to boot things up.
It's even helpful when you're untethered from your phone (gasp!), as the mounted sensor attached to the scale will give you an LED reading of the gas level when you press it. Hank Hill would approve.
