RE: Straight runs for flowmeters

The amount varies per customer spec, but it is usually approx. 2" required space between 2 parallel runs of pipe for wipe-down. More would usually be factored in if it weren't for the tight spaces we have to fit everything into.

Hmmm, maybe cryogenic piping would fit in that group as well (although the
extremely low temperatures would sort of set it apart). When you mention clearances, what does that mean?
