Abstract:
1. A method for determining the level of a carbonated fluid in a container comprising: obtaining a container having an outlet for a first carbonated fluid and an inlet for introducing carbon dioxide; said container having a first carbonated fluid region therein; a first carbonated fluid being present at an original level in said first carbonated fluid region of said container; said container, for when in use, having said first carbonated fluid at least partially removed from said container while introducing carbon dioxide to said container thereby forming a second carbonated fluid region; mounting on at least one exterior surface of said container at least one temperature-measuring device in the form of an elongated thin strip; at least one said temperature-measuring device being located in a region of said container where said second carbonated fluid region is formed by removal of said first carbonated fluid; initially observing a first temperature in said first carbonated fluid region of said container when said first carbonated fluid is present in said first carbonated fluid region of said container; subsequently observing a second temperature in said second carbonated fluid region of said container after a portion of said first carbonated fluid has been removed; and, correlating the difference between said first temperature and said second temperature to the level of said first carbonated fluid in said container.
