01 / DESIGN CONTEXT

A defined
engineering boundary.

Oil & Gas / Process Packages

Flow computer · pressure regulation · analyzers · remote I/O

Illustrative design assumptions
  • Representative industrial gas metering / pressure regulation skid
  • Defined sensor, analyzer and flow-computer interface boundaries
  • PLC / RTU / telemetry signals on client-provided interface list
  • Boundary: documentation, not custody-transfer verification, metrology approval or hazardous-area classification

Technical context: API MPMS / AGA / ISO 5167 or ISO 17089 where relevant, IEC 60079 and IEC 61511 where applicable; requirements confirmed from the actual project and metering technology.
