With the Refuel Smart Propane Tank Gauge you’ll never get caught off guard by said BBQ bummer again. The Refuel is a smart tank gauge designed to ensure your tank is ready when you need it. It consists of a ring base of reinforced plastic and rubber on which a barbeque’s propane tank is placed. This ring acts as a scale to measure the weight of the tank and calculate the amount of fuel remaining. Gas levels can also be tracked remotely through the Wink app, available for iOS and Android devices, and it tracks the user’s barbequing habits over time to calculate the average tank life in days and the average number of grills per tank.
