How can I check how much gas is left in the gas bottle?

If you have a Calypso gas bottle, you can easily see its content. Thanks to the transparent window you always know how much gas is left in the bottle.

If you have a steel gas bottle, there are two ways to check how much gas is left in the bottle.

  1. Method 1: To check how much gas is left in the gas bottle you can subtract the weight of the empty bottle from the total weight of the bottle.
    You will find the weight of the empty gas bottle (the terra weight) on top of the bottle valve. Put the full gas bottle on a scale to measure the total weight of the bottle. Subtract the weight of the empty gas bottle from the total weight and you will know how much gas is left in the bottle.
  2. Method 2: With your hand, touch the side of the gas bottle while it is connected and in use. The gas bottle will feel cooler where the gas bottle still contains liquidised gas. The gas bottle will feel warmer where the liquidised gas has vaporised. This method is less precise, but it is fast and indicative.
