Miscellaneous

• Multilingual version (English, French, German)

• Various issues with the print preview and with the PDF export, like for example missing identifiers or wrong font sizes, are addressed.

Restriction Orifice Plate

• At the calculation of the residual pressure loss of multi-hole orifices with compressible media, the test of criti-cal flow conditions was not always performed correctly when the number of holes was decreased.
• The calculation of the throttle orifice d gives incorrect results in some cases.

Control Valve

• Revised reliability prediction for multi-stage valves with compressible media
• An issue with the calculation of the valve authority (Δp100/Δp0) of valves with resistance structures and compressible media is addressed.

Differential Pressure Flow Element

• Improved accuracy of the stress calculation of orifices with materials, for which not all properties  are present in the database.
• The maximum pipe roughness with orifices according to ISO 5167:1995/A1: 1998 were calculated falsely following the ISO 5167 edition of 1980.

Thermowell

• The uncorrected fatigue stress limit was not displayed correctly using thermowells with mounting type “Socket” according to ASME PTC 19,3 TW-2016.
• In very rare cases the natural frequency of thermowells according to DIN 43772 wasn't calculated correctly.

Details about other improvements and error corrections can be found on the download page in the version history and in the known bugs section.
