I've noticed that manufacturer are either using Preset or Calculated Flow Configurations..
What is the proper way to use this connectors?
Thanks

As far as I know I always use a preset value for the flow config on end of the line units which then allows the pipes to calculate the total flow assuming that there are no open ends and all the flow directions are correct. A connector on equipment can then total up the flow if the connector is set to calculated.

I posted a SUMMARY of five videos that are hosted at Inside the System (Autodesk Revit MEP and AutoCAD MEP blog). There are couple that address your question specifically and the others are worthwhile for reference sake. Their blog has some explanatory text as well as the videos. My blog is just echoing them to get the word out!
Hope they help!
Thanks for the reply..
I have seen those videos before..
I wish they had a video showing Pipe Connections to VAV and Heating Coils, etc..
Seems like for the Dry Side of things is a bit more straight forward, but when it come to the Wet Side is a little bit more complicated then it seems..
I have a Wet Model that I'm connecting from a Central PLant with pumps and such to Rooftop Units, to Vav's, to Duct Heating Coils, to Radiant Manifolds and to radiators... some piping show the flow sum and then some piping has them at 0 flow..
Thanks again!
I wrote about "loops" related to Fixture Units (another kind of "flow") last week. For piping to calculate this information it needs to "start" and "end", if the path permits the flow to loop back somehow the calculation/addition ceases. Depending on the situation you might need to interrupt a loop so that flow can work even though it isn't technically correct from a real world perspective.
