Achieving that goal begins with a sample probe wake frequency calculation based on static and dynamic stresses relative to process temperature and pressure. Flow-induced vibration, for instance, can lead to fatigue failures. And erosion from particulates weakens probe integrity. You want to avoid both with the correct calculations.


Well, using a thermowell as an example, factors such as wall thickness, unsupported length, root and tip diameter, process fluid velocity, and thermowell natural frequency, as well as criteria such as Strouhal Frequency and Reynolds Number may all be part of the calculation. From a practical standpoint, calculating sample probe wake frequency under a range of process conditions is the shared domain of instrument engineers and process engineers.

Proper Thermowell DesignIt is critical to the safety of the process plant that thermowell vibration calculations (also known as: Wake Frequency Calculations/Analysis, or von Karman Calculations/Analysis) be performed for every thermowell, especially for new applications and for applications in which any of the characteristics of the process flow have changed.At your request, Daily Thermetrics will perform thermowell vibration calculations to ensure proper thermowell design. Furthermore, we can recommend the proper design solution to overcome a high velocity issue.Proper thermowell design is a very important topic, especially to those who have experienced thermowell failure out in the field due to stress and vibrations resulting from improper thermowell design. Thermowell failure can cost the end user hundreds of thousands of dollars in lost production time. Moreover, the legal implications involved in such an event are both time consuming and costly. It is much less costly to properly design a thermowell up-front using the proper tools (thermowell vibration calculations).Daily Thermetrics has been designing and manufacturing thermowells since 1973, and we currently employ the latest thermowell vibration calculation method, ASME PTC 19.3 TW-2016 to verify the thermowell design for each specific application. Unlike the older, outdated ASME PTC 19.3 version, the ASME PTC 19.3 TW-2016 takes into account the characteristics of the actual process with which the thermowell will come into contact. The process density, viscosity, and even the nozzle project length are now key inputs in this calculation method (ASME PTC 19.3 TW-2016).Calculation methods such as those developed by J.W. Murdock or even J.E. Brock can be performed by Daily Thermetrics upon special request, but it is important to note that these older methods fail to consider all of the criteria incorporated by ASME PTC 19.3 TW-2016.Thermowell TraceabilityA very important feature we offer (free of charge with every order) is 100% full traceability for every thermowell manufactured by Daily Thermetrics. We do this using a unique serial number etched onto each thermowell. Also etched onto each thermowell we manufacture is our company name and telephone number. This allows the end user to know who manufactured it, and using the serial number, we can tell you when you ordered it, what the part number is, who welded it, who inspected it, and, more importantly, we can provide material certifications for the thermowell (and flange) by using the serial number. The thermowells we manufacture are therefore fully traced, both in the labor aspect, as well as the material aspect of each.Remember: Currently, the industry uses only tag numbers to identify a thermowell. However, the tag number never changes, no matter how frequently the thermowell is replaced with a new one. Having a unique serial number for each thermowell ensures vendor accountability for each and every thermowell.

Use this setting to enable software updates on Configuration Manager clients. When you disable this setting, Configuration Manager removes existing deployment policies from clients. When you re-enable this setting, the client downloads the current deployment policy.


If delta content is unavailable from distribution points in the current boundary group, you can allow immediate fallback to a neighbor or the site default boundary group distribution points. This setting is useful when using delta content for software updates since the timeout setting per download job is 5 minutes. The following options are available:


No (default): The client honors the fallback time (in minutes) defined by the Boundary Group relationship when it's allowed on the software update deployment. Delta download content may fail with a timeout even if the update content is available on a neighbor or the site default distribution point group.


Finally, although we have designed the free website above to be enough for basic needs, we also aim to cater for the more sophisticated needs of many of the energy professionals, multi-site organizations, academic/government researchers, and energy-software developers who use our system.

And of course you can download heating and cooling degree days for locations worldwide through our free website. If you've not done so already, why not head back up to the top of this page and give it a go?!


Tom prepared a report on the pedestrian bridge's natural frequency and posted it to his vibration blog. Using the vibration data captured and the free VibrationData Toolbox he developed he was able to determine the bridge has a fundamental frequency of about 2.2 Hz with 0.16% damping.

The structural modelling using finite element methods does not present any difficulties. However the part of the analysis which presents special problems is the modelling of the loading in a short-crested sea. General purpose finite element programs do not provide methods for calculating the loading in a stochastic, short crested sea, and additional routines should be included in order to do the job. In conclusion the use of general purpose finite element programs is - time consuming, uneconomic, and susceptible to errors. The program cgFLOAT has been developed especially for long floating structures in short crested sea loading. The dynamic response can be calculated via a frequency or time domain analysis. Theories and methods for hydrodynamic loading, short-crested waves, directional wave spectra, sea state simulation, and stochastic dynamics are included in the calculation routines. The computer code has been optimized taking into account the special characteristics of the structure and the loading. For the response calculation a Monte-Carlo simulation is used. This method is considered to be more advantageous over the usual frequency domain analysis, which is the only alternative, because it reduces the computational cost considerably and can be used for frequency and time domain analysis. It is based in simulating sets of nodal load series and calculates the structural response by deterministic dynamic analysis in frequency or time domain. The expected response values are obtained in the end by calculating the ensemble statistics between the simulated cases. The basis for computing the sets of nodal load series is the wave coherence along the structure, which is obtained from the directional wave spectrum.


For pontoons of rectangular cross section the hydrodynamic coefficients (added mass, added dumping and hydrodynamic forces) for various frequencies are automatically evaluated by the program. For other cross sections you may input the hydrodynamic coefficients for certain wave frequencies and the program interpolates between them for the necessary values in the response calculations. The short-crested sea state is specified by the wave spectrum and the wave coherence. Typical wave spectra like Pierson-Moskowitz, JONSW AP, are computed from their parameters by the program. Other kinds of spectra can be used by inputting their f and S(f) values. Wave time series are simulated from the spectra, via various methods, by the program. The wave correlation is handled by specifying the coefficients of an exponentially decayed wave coherence, or by specifying the nodal load correlation directly. In the case of boat wake analysis the speed and characteristics of the boat wake are specified. For the frequency domain analysis, the frequencies for the computation of the frequency response function can be specified or they are computed by the program after their number is specified. For the time domain analysis, participating modes, integration method and parameters, accuracy, time interval and time length are specified. The user specifies the various analysis paths, units, simulation methods and number, and required printed or plotted output quantities. For all the cases if general parameters are not specified by the user, default values assigned by the program. Mode shapes Frequency response
