I saw this summary post pointing to a blog post by automation hall of fame member, Greg McMillan. His Control Talk blog post, Checklist for Best Inline Flowmeter Performance, highlight some considerations for improving operational performance. These include:

1. Do the meters’ threshold sensitivity, repeatability, and drift meet application requirements?
2. Does the meters’ rangeability and permanent pressure loss meet application requirements? (Maximum possible rangeability: 15:1 vortex, 50:1 turbine, 100:1 magmeter, 200:1 Coriolis)
3. Do O-rings and gaskets meet worst case corrosive and temperature operating conditions?
4. Are gaskets not projecting into flow stream?
5. Is meter centerline concentric with piping centerline?
6. Do the upstream and downstream straight run lengths for vortex meters meet the ASME guideline for 0.8 beta ratio flow tubes (e.g. 20 pipe diameters upstream for long bends)?
7. Do the upstream and downstream straight run lengths for turbine meters meet the ASME guideline for 0.6 beta ratio flow tubes (e.g. 10 pipe diameters upstream for long bends)?
8. Do the upstream and downstream straight run lengths for magnetic flow meters meet the ASME guideline for 0.4 beta ratio flow tubes (e.g. 5 pipe diameters upstream for long bends)?
9. Have asymmetric profiles and swirling been minimized by piping design and straightening vanes by special conditioners for profile distortion for turbine and vortex meters?
10. Is the maximum kinematic viscosity less than the maximum for vortex meters?
11. Is the minimum and maximum velocity within limits for magnetic, turbine, and vortex meters?
12. Is the minimum Reynolds number greater than the minimum for vortex meters?
13. Are flow meters in vertical lines installed with flow up?
14. Is maximum vacuum (e.g. after steam cleaning) less than maximum for lined magnetic meters?
15. Is the minimum fluid conductivity (e.g. low water) greater than minimum for magnetic meters?
16. Are there no bubbles in magnetic, turbine, and vortex meters?
17. Is maximum % bubbles and solids less than maximum permitted by Coriolis meter software?
18. Is particle abrasion negligible for U-tube Coriolis, magnetic, turbine, and vortex meters?
19. Is particle concentration high enough to require a straight tube Coriolis meter?
20. Is the minimum fluid lubricating effect better than minimum for turbine meter bearings?
21. Is the fluid always a liquid (e.g. no flashing) for magnetic meter?
22. Are Coriolis and magnetic flow meters completely full at zero flow?
23. Is signal grounded to zero when no flow to prevent sloshing errors?
24. Is maximum piping vibration less than the maximum permitted by Coriolis and vortex meters (e.g. is there a vibration damper for isolation)?
25. Are bubbles and solids not trapped in U-tube Coriolis, magnetic, turbine, and vortex meters?
26. Are magnetic meters properly grounded to earth and for lined pipe are there ground straps between pipe flanges and meter?

Are there any considerations to this checklist that you'd add (or subtract)?
