No more guessing when you need to refill your gas bottle by shaking the bottle or other unscientific methods. This magnetic gas level indicator measures the gas level in the bottle accurately. Easy magnetic installation and you can use it from bottle to bottle.
Apply the indicator near to the base of your cylinder, below the middle weld line, out of direct sunlight.
Turn the gas on (this indicator works only when the gas is on).
Wait 2–5 minutes before taking the reading.
Read the indicator:
If the cylinder is full, the gas level is above the indicator, no change in colour will show.
When the gas level falls within the range of the indicator, the colour will change in at least one of the bars depending on the temperature outside.
If more than one bar changes the leftmost bar will indicate the gas level.
