The Measurement Gap Costs You Money

In petroleum custody transfer, measurement errors compound. A fraction of a percent in meter factor deviation across high-volume pipelines translates directly to lost revenue, failed audits, and regulatory exposure.

Archangel Industries closes that gap. Our consultants bring decades of hands-on experience with flow meters, pipe provers, and the API standards that govern every barrel transferred.

Core capabilities

Our Services

Measurement System Audits

Comprehensive audits of custody transfer measurement systems for pipelines, terminals, and production facilities. We identify measurement uncertainty, equipment deficiencies, and procedural gaps before regulators do.

  • Full system audit report
  • Risk-ranked findings
  • Corrective action plan
  • Regulatory gap analysis

Flow Computer & SCADA Configuration

Configuration, verification, and commissioning of flow computers and SCADA systems for custody transfer applications. We ensure your calculations conform to current API standards.

  • Flow computer configuration files
  • Verification test records
  • SCADA tag documentation
  • Commissioning sign-off

Regulatory Compliance Support

Preparation and support for regulatory inspections, audit responses, and compliance documentation. We know what inspectors look for and help you stay ahead of findings.

  • Compliance gap report
  • Corrective action tracking
  • Inspection preparation checklist
  • Documentation package

Training & Knowledge Transfer

Hands-on training programs for measurement technicians, engineers, and operations personnel. Courses cover meter proving fundamentals, API standards, uncertainty analysis, and field troubleshooting.

  • Custom training curriculum
  • Field exercises
  • Reference materials
  • Competency assessment
