Abstract
A liquid in glass variable angle thermometer tube includes a bulb containing a volume of liquid with a known coefficient of thermal expansion and having a sensing portion for sensing temperature, a glass capillary column for reading the height of the liquid therein, and a flexible metal capillary connecting the sensing portion to the glass capillary column. The flexible metal capillary is in fluid communication with the sensing portion and the glass capillary column such that the liquid in the bulb is permitted to transfer from the sensing portion to the glass capillary column. The bulb is connected directly to the flexible metal capillary and includes an extension portion that is separate from the volume of liquid and the extension portion supports the bulb remote to the temperature sensing volume.
