That's 100% true. I'm no expert either, but here's what I earned selling industrial valves and flow meters for 5 years: Piping bends mess with a flow meter so badly that you can't get an accurate flow measurement unless the meter is installed in a straight section of pipe. And the meter must be installed several "pipe diameters" (as many as 10) distant from piping bends.
Same is true of control valves. They need straight sections of pipe before and after to work properly, reduce noise, and event prevent damage.
TMI?
