A part of the review has been auto-translated.
Was curious how this device works. It has a grid of temperature sensitive dots made with liquid crystal. Each vertical column of dots responds to a fixed temperature. Placing the device on a tank causes the liquid crystal columns to show the temperature of the tank at various heights. An unused tank will be at uniform temperature, so a single vertical column will display. A used tank will have an upper section that is at a lower temperature than the lower section due to the boiling liquid fuel in the bottom section of the tank. Thus the device will show two half columns, one above the liquid, indicating where the liquid to gas transition is, and hence the amount of fuel remaining in the tank. Magic.
excelente producto

Good quality for the item price
I was surprised by this little indicator really looks like it can tell you how much gas you have left. Features: - It is magnetic sticks on any metallic surface just make sure to clean a little the area where it will be put. "From what I understood as soon as the meter turns blue means that the gas is about to end. - It is measured based on the temperature of the gas so you can measure it only use a little your gas in your daily activities. - It should be put on the bottom middle). - has an indicator for when it is winter and another for when it is summer. It is well versatile I will be checking if it is true when the gas is finished I will gladly answer your comments thank you :D
Very good
Not checked if it works.
