### Operating conditions

| Max. process temperature, process pressure | Depending on: ■ Thermowell design - Dimensions - Material - Coating - Flange pressure rating ■ Process conditions - Flow rate - Density of medium |
|---|---|
| Wake frequency calculation (option) | The calculation in accordance with ASME PTC 19.3 TW-2016 of individual thermowells minimises the risk of dynamic damage that can be caused by the vortex shedding of a Kármán vortex street (Vortex Induced Vibration; VIV). In addition, the static loads due to lateral flow and the process pressure are calculated depending on the temperature. The calculation can be carried out independently using an online tool or as aWIKA engineered service (subject to charges). → |
