Hello All

I am new to this forum and not sure whether this is the right place to post my thread or not. Please excuse me if this is not correct or if this question has been asked before.

Presently I am working on custody metering system design for stream application and have following question:

a) We are using Flow Nozzle (ISA 1932 type) for measuring steam based on my client's requirement. Is there another type / technology of meter that can be used for measuring steam in custody transfer application?

b) I understand that API RP 551, gives guidelines for installation of process instruments in all type of application. Is there any specific standard that provides guidelines for steam application?

I would highly appreciate if someone can help me to answer this question.
