I've installed the latest up-grade for PVElite2005. After instalation, at starting of software i choose "Metric Standard, units for Nozzle Diameter will be millimeters". In nozzle calculations the diameter of pipe apear in inches.
What's happening?

Adrian,

All files prior to the February build store the nozzle diameter internally in Imperial Units. Any files created before this new build will diplay the nozzle diameter in inches both in the input and the output. When a new job is created and you have selected either ANSI Metric or International Metric (Din Standards at the moment), the nozzle diameter will be in millimeters regardless of the other units. The benefit here is that you can now specifiy diamters such as 200, 250, 300 etc. Also note that the diameter selector is smarter now and only displays the diameters that are associated with a particular schedule. This should make future work easier when dealing with Metric pipe sizes.

The databases for pipe sizes are also now stored as text and are extensible.

If you wish to continue to use the original 2005 version, it could be installed in a different directory allowing you to finish existing jobs. If the model is fairly simple, you may opt to re-enter the vessel information. This enhancement to the program should prove to be a great benefit to Metric users.
