Technical background

When the gas cylinder is used, the gas that is liquid in the cylinder becomes vaporous. This causes a drop in temperature. The temperature in the upper part of the bottle (where the gas is gaseous) is therefore different from the temperature in the lower part of the bottle (where the gas is still liquid). Exactly these different temperatures can be displayed by the USI-Gas level indicator. The vertical bars of the indicator show the temperature difference at the gas cylinder. Which bars light up also depends on the ambient temperature. This indicator works at an ambient temperature (air temperature) of 0°C to 50°C.

Only when the level drops below the level of the upper edge of the USI-GLI will color differences appear in the column.

  • USI-GLI can safely and accurately measure the gas capacity, according to the gas temperature test.
  • Temperature range of -10℃~ 120℃.
  • Will actually show you when the gas bottle is almost empty, before you run out!
  • Works while the gas is beeing used
  • Save money by using more gas from each cylinder
  • Safe & accurate
  • Reusable
  • Compatible with Propane
  • Works on LPG (propane) & butane cylinders
  • Magnetic backing allows for easy reuse on exchange bottles
  • Comes with instruction
  1. Place your Gas Level Indicator (USI-GLI) on a clean area on the lower half of the cylinder.
  2. Turn on the gas and wait 10 minutes before you can read your Indicator. But it’s to keep in mind that the gas level indicator gives you the information of the actual gas level in case it is beeing used.
  3. In the cold season (-15°C to 15°C) the bar on the left will be active, and in the warm season (15°C and more) the bar on the right will be active.
