Request Information
Vortex thermowells isolate and protect a temperature instrument's sensing element from pressurized, high velocity and corrosive media. They are used when standard Flanged Thermowells cannot pass ASME PTC 19.3 TW-2016. The helical Strake is designed by using Computational Fluid Dynamic analysis. They ensure longer life and accurate measurement while allowing the sensing instrument to be removed without shutting down the process. A wide selection of materials, sizes and dimensions are available.
