RE: Straight runs for flowmeters

Ok I see what you mean. I say, yes. They all work in similar materials, similar instruments, and similar environments. One of the hardest things that I've seen for designers working for the first time with Pharm/food/semicon industry are the slopes and clearances that have to be maintained for a system to be certified. And the cleanliness issues that have to be maintained when the system you're designing is going in a clean room. Some of the contract pipers we've hired just don't get it. Why does this line need to slope 1/4" per foot? Why do they need that much room to clean between pipe runs? Etc, etc.

As a subgroup of the piping design "discipline", I mean. I.E., those who
have experience in one of these 3 fields wouldn't take long to get up to full speed if moved to one of the others.
