To throttle before or after...That is the question ..:)
(OP)
We have an orifice plate to measure the flow and then a throttling globe valve to balance the flow in each branch in our system. Each branch has an orifice plate upstream of its throttling valve. I would like to know what are the advantages/disadvantages of throttling before the orifice plate vs throttling after the orifice plate? Thanks!

Other than that unless there is a big pressure loss in a gas system which means your size goes up, there's not a lot in it IMO.

Turbulence doesn't do much for accurate measurements.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
