API standards relating to instrumentation in Oil and Gas Industry

(OP)
Can any one suggest API standard numbers applicable to instrument specifications for Oil and Gas industry?

Thanks in advance.

RE: API standards relating to instrumentation in Oil and Gas Industry

The old RP 550 was obsoleted and is in the process of being replaced by RP553 for control valves, RP-554 for control systems, RP 556 for fired heaters (still in progress) and I can't remember the flow RP number which also may be a work in progress.

RE: API standards relating to instrumentation in Oil and Gas Industry

API 554 and API 555 relate to sampling and analytical instruments.
