We’ve developed our own method of measuring the amount of propane left in our tanks over the years. We simply pick it up, and give it a little shake. Unfortunately this method has been proven to be a huge hit or miss, and that’s what makes the Truma Propane Tank LevelCheck so awesome.
Rather than guessing the amount of liquid left in your tank, this little device uses ultra sound to let you know exactly how much juice you have left. Simply place the device against the tank, and the LED lights will illuminate green to indicate how much you have left, and red when you’re getting low. This could be a huge help for those of you that prefer to grill with gas.
