Description:
The display of the temperature differences on the GLI only works when the gas bottle is "consumed", i.e. not just turned on, the gas must escape. The colour scale on the display first depends on the outside temperature. Only when the gas bottle is turned on and "used up" can you see what the filling level is after about 5 to 10 minutes. The level indicator must be placed on the lower half of the bottle. Only when the level drops below the level of the upper edge of the GLI, colour differences appear in the column.
Since the lower, liquid area of the bottle becomes cooler than the gaseous state at the top, the gauge reading in the upper area will be different. The colour transition on the scale is then the level.

Usage:
The gas level indicator must be placed in a clean area on the lower halves of the cylinder. (magnetic)
Open the gas valve of the bottle and wait 10 minutes before reading your display.
In winter, the bar is active on the left side and in summer, the bar on the right side is active.
Temperature range is: -10 degrees to 120 degrees - products may have different colours, blue, green or brown - when green is displayed, the temperature is normal.
