U.S. Gauge recommends the use of a thermowell in conjunction with a bimetallic thermometer when the application involves a corrosive medium, high pressure, or high flow velocity. Some specific uses include protection for unarmored liquid-in-glass test thermometers or other temperature sensing elements with a maximum diameter of .25”.
