Hello,
We have a startup valve, that has to open on startup etc.
We also want to know the flowrate throughe valve.
They told me that in previous projects they used the SHS Function Block from Siemens and that is was locked.
The previous developer is gone, no source codes from these previous projects.
But I have a nice document which says:
calculation for the flow is approximating steam flow through it:
By using steam temperature and pressure and valve characteristics (to be provided along with the valve – it is not linear) while using SHS function block (siemens block).
Who can tell me more about this SHS Function Block?
Thanks in advance.
Regards,
Andre Janssens
