Meet Tank Utility’s smart meter: a nifty device that lets you monitor your propane tank level and usage on your smartphone. The device mounts to your propane tank magnetically and has a waterproof design. You can use the companion app to find out when you are running low on fuel. You can also track your consumption history, see pricing options, and order a delivery.
Tank Utility is easy to install and helps you identify leaks and get notified when you are running out of fuel. You can get it on Kickstarter.
