Roxar™ Subsea Multiphase Flow Meter

Next-generation subsea multiphase flow meter for both oil and gas wells, engineered for reliability, accuracy, and in-situ self-verification

Emerson’s new Roxar Subsea Multiphase Flow Meter builds on 30+ years of field‑proven expertise and 3,000+ installed meters worldwide. Designed as an innovative hybrid platform, it combines impedance and microwave technologies with advanced sensors and software to deliver robust, self‑verifying, highly repeatable measurements - boosting confidence across complex subsea fields and tiebacks for asset life.

Key Features

  • Hybrid multiphase measurement platform combining impedance, microwave, density, and mass flow sensing
  • Unique hardware, software and functional redundancy
  • High degree of in-situ verification & self-diagnostics capabilities
  • A unique, integrated 2-in-1 salinity system
  • Tolerant towards scale and wax build-up using nano technology treatment
  • Non-intrusive flow path
  • Built-in PVT engine to handle complex fluid changes
  • Full GVF and WLR operating range, supporting tiebacks and complex field developments
  • Designed for higher confidence in data, supporting allocation, regulatory, and multi‑stakeholder requirements
  • Field‑proven core technologies to minimize residual technology risk in a next‑generation solution
  • Reduced size, weight, and lead time, aligned with evolving subsea EPC and operator needs
