Which type of differential pressure flow meter has good resistance to hydrogen sulfide corrosion?
Thread Content
It has relatively good resistance to hydrogen sulfide corrosion; a 275 manual operator can be used, and it is compatible with the original Rosemount three-valve assemblies. Thank you!
Then use 3051; there aren’t many other options. Use 316 for the material – consult the manufacturer.
What is the difference between 1151 and 3051?
The key to corrosion resistance lies in the material, not the type of instrument.
For diaphragms resistant to hydrogen embrittlement, it is best to use materials such as 316L gold-plated or Hastelloy; you can also use 3051 transmitters.
Thanks! :handshake

[/The owner is asking for resistance to hydrogen sulfide corrosion, not hydrogen embrittlement – the two are different, right?]
