Thermowell Calculation Report Sample EMERSON-2011-Thermowell-Calculation-Report.pdf
The Thermowell Selection video is just one of six short educational videos entitled Temperature Insights from Emerson Process Management. The series provides insight into effectively and efficiently measuring temperature in a manufacturing process.
Thermowells are essentially a circular cylinder installed like a cantilever into the process piping. They provide process condition protection and a process seal for temperature sensors. As a process fluid passes around the thermowell, low pressure vortices are created on
WHY USE VELOCITY COLLARS? The goal of a velocity collar is to reduce the effective unsupported length of a thermowell. In theory, this helps accomplish two things: 1. Eliminates vortex-induced failures. Shorter unsupported lengths raise the natural frequency of a
