Start with the essentials
Process conditions and drawing values come first, so the calculation has a clear place to begin.
About the calculator
Quick on the surface.Serious underneath.
Wake Frequency Calculator is built to make day-to-day thermowell design checks easier, while keeping the engineering depth needed for demanding designs. Start with the process and drawing values; bring in deeper controls as the calculation requires them.
Why it exists
Serious engineering does not need a difficult interface.
Thermowell design brings process data, geometry, material behaviour, vibration, stress and pressure together. The engineering is necessarily detailed; the journey through it does not need to feel complicated.
The calculator stages that detail. It asks for the core design information first, adapts to the proposed connection and keeps advanced inputs available in the same workflow when the job needs a complete assessment.
One calculator, two depths
Start simple. Continue when needed.
Quick design view
Enter the essential process and drawing values to review preliminary design behaviour and obtain a clear calculated PASS or FAIL for the checks that can be performed from those inputs.
Detailed assessment
Add material, fatigue, pressure and applicability detail without starting again, then complete the engineering basis needed to take the calculated result forward.
Product principles
Simplicity is part of the engineering.
Show only what applies
Connection and geometry choices bring forward the fields that matter to the proposed construction.
Keep depth within reach
Advanced material, fabrication, pressure and applicability controls remain available without crowding the first pass.
Make the result understandable
Wake, stress, fatigue and pressure outcomes stay separate, with a clear status and next action.
Where it helps
One workflow across the design journey.
Use the level of detail that matches the decision in front of you.
Early design screening
Get a preliminary view of a proposed geometry before all project evidence is assembled.
Design refinement
Change the service conditions or thermowell dimensions and see which part of the result moves.
Specification support
Bring the process, connection, geometry and material basis together for a clearer hand-off.
Engineering review
Open the deeper calculation detail when a design needs checking, explanation or project records.
Under the surface
The technical capability is there when you open it.
The main journey stays focused. These deeper calculation areas remain available for detailed design and engineering review.
Engineering foundation
Easier to use does not mean lighter engineering.
The calculator implements a defined calculation path from ASME PTC 19.3 TW-2016 and identifies unresolved inputs and unsupported implemented methods. The calculation core is regression-tested against the published Section 8 worked examples and protected by automated change controls. A result supports engineering judgement; it is not ASME certification, manufacturing approval or a substitute for reviewing the installation.
Start simple. Go as deep as the job demands.
Begin with the process and proposed thermowell, then bring in the full engineering detail when you need it.
