Upstream and downstream pipes for Rosemount 8712?

Flow Q&A

I plan to install a new Emerson magmeter, model 8712. Do I need to install upstream and downstream pipes for this kind of meter?

Expert’s answer: Upstream and downstream pipes for Rosemount 8712?

Do you need to install upstream and downstream pipes for Rosemount 8712, you ask. Then you need to know that nearly all brands have the same installation specs. Also, you should have little trouble remembering them, as they’re fairly easy. Ready?

Okay, before the device you need five straight pipe diameters upstream. Then after the device, you need two pipe diameters downstream from the electrode plane. There you go!

If you install the device using these simple rules, then you should get the accuracy stated in the manual.
