We purchase Elite coriolis meters for piping leak detection purpose. The meter is installed according to the above photo link
1. Is the pipe support sufficient for the meter
2. If the is pipe stress or displacement, can this effect be zerorised during meter calibration
3. Is there guidance of max allowable nozzle load onto coriolis meter flange
4. Is there examples of successfully completed Elite flow meter in “flag” position?
We have minimal space to route the pipe and placed the support, thus this design was chosen
Thanking you in advance for your inputs

In reply to Ayuko Morikawa:
Hi Ayuko, Thank you for your valuable reply. We understand that meter's support through pipe flange is acceptable. Based on our pipe flex check, the piping configuration will yield some displacement on Coriolis meter flange during operating condition (i.e. up to 2.5mm at top flange and 0.5mm at bottom joint from zero flow condition). The stress on meter flange is less than the allowable stress limit that you shared. Below schematic illustrates the displacement in 1D (pardon me for the poor hand dwg)
Will the displacement affect the meter's performace? To achieve zero displacement on coriolis meter flanges, independent welded support is needed next to meter flange joints. Is this necessary? Looking forward to your reply and thanking you in advance for your further advice

Thank you very much for sharing this information. I have been looking for this information.
I remember that about 15 years ago it was specified in your manuals that no external loads should be applied as this could affect the measuring performance, i.e. the meter zero.
Other manufacturers have clamed that their meter's are not affected by external loads whatsoever. Which is kind of hard to believe and not credible in my opinion.
I appreciate this openness. Still I miss two things
