Api Rp 551 Pdf Today
The original API RP 551 was published in 1993 under the title "Process Measurement Instrumentation." This first edition established the foundational principles for selecting, designing, and implementing measurement systems in refining and petrochemical facilities. The 1993 edition was reaffirmed in 2007 before being superseded by the second edition.
