Propane tanks have needed a gauge to inform users how much gas is left in the tank since forever. And since no one appears to be doing anything about it any time soon, someone made Refuel, a third-party device that lets you check your tank’s gas levels at any time.
Another product of the growing partnership between Quirky and GE, the device consists of a plastic and rubber scale that you place under the tank, which is tethered to a disc with magnetic backing that holds the sensors, LED indicators, and other electronics that you can stick onto the gas grill’s frame. It works by measuring the weight of the tank, then calculating how much gas is left based on that.
You can check gas levels by using the onboard LED indicators (tap it to light up), as well as on a smartphone using Quirky’s Wink app. It also sends alerts when your propane is running out, so you never have to be stuck with an empty tank right in the middle of a backyard cookout. The rig can work on any gas grills that don’t use hanging propane tanks (yes, even that awesome BBQ Dragster), with heat-resistant parts, so you never have to worry about things getting too hot. Dimensions are 9.4 x 9.4 x 2 inches for the base and 3.5 x 3.5 x 1 inches for the disc. It powers using four AA batteries (good for 60 days).
