ChasB Posted August 18, 2023 Share Posted August 18, 2023 Can anyone tell me what the aluminium collar on the top of a Calor Gas bottle means? Does the information on this collar help me to work out what gas I have left in the bottle? Thank you for you replies. Quote Link to comment Share on other sites More sharing options...
Robinhood Posted August 18, 2023 Share Posted August 18, 2023 Stamped on it is the tare weight, which you can subtract from the weight of a full/partially full bottle to determine the weight of the gas therein. It is slightly complicated, however, in that the weight on the collar is in pounds and ounces (the numbers to use should be obvious), even though the bottles are sold in kg. 🙄 Quote Link to comment Share on other sites More sharing options...
ChasB Posted August 18, 2023 Author Share Posted August 18, 2023 So am I right them a 13 kg Calor Propane bottle with an aluminium collar on the top of 32.00 is 32 pounds. That’s equal to 14.51 kg. The bottle weighs in at 17.7kg. Does that mean I have 3.19 kg of gas left??? Quote Link to comment Share on other sites More sharing options...
Robinhood Posted August 18, 2023 Share Posted August 18, 2023 32.00 is in the correct lb/oz range for a 13kg tare weight, and your calculations look about right. Quote Link to comment Share on other sites More sharing options...
