How to tell how much propane is left in your tank?

  • Check the level of your propane tank without a gauge
    – Fill a container with hot water from the tap. You don’t need boiling hot water to do this test, so just use the hot water side of a faucet and you will be set to go. Away from the valves of the tank, pour the water down the side, starting at the top. You are going to let the water just run down the side of the tank and drip off back to the ground. Pour all of the water you have onto the tank – it should take a few seconds to complete this part of the job.
  • “Feel for the Line”
    – Once the water is poured, take your hand and place it on the side of the tank where you have poured the water. By quickly running your hand over the metal tank, you should notice there is a significant temperature difference at some point along the way. Part of the tank is going to feel warm, while part of the tank will feel cold. The warm part of the tank will be where there is air behind the metal, while the cold part of the tank is where the gas remains. So, by finding the point where warm metal turns to cold, you can figure out exactly how much gas remains inside.Once you find the ‘line’ between hot and cold, look at that spot in comparison with the tank as a whole. Do you have half of your tank left? More? Less? Whatever the case, you will now know within a very small margin of error how much propane remains.
  • Be Smart
    – It is always important to keep in mind that propane, as a compressed gas, should be kept in a tank which is in good physical condition. If your tank is showing signs of age, you may wish to consider a replacement at some point in the near future.
