Roxar Subsea Wetgas Meters
Roxar Subsea Wetgas meters provide highly accurate water, gas and condensate flow rates, reducing risk and improving flow assurance.
The advanced meters deliver unparalleled water sensitivity, accuracy and rapid response for reliable production measurement.These include the industry’s first built-in salinity-measurement system, which provides information vital to protecting subsea well and pipeline integrity and supporting metering/allocation strategies in gas and gas condensate fields.

  • Maximize accuracy with multivariate analysis and three-phase measurement based on microwave and gamma densitometer
  • Know if formation water is entering the flow with the industry’s first dedicated online salinity-measurement system
  • Detect changes as little as 0.2 ppm in water content of the flowing well – sensitivity never before achieved
  • Act immediately to protect subsea system integrity with measurement speeds of 20 times per second
  • Simplify installation and integration with a compact design
  • Realize maximum performance over the field’s lifetime with field-proven reliability and full redundancy
  • Ensure valid readings with pressure, volume and temperature (PVT) measurements independent of water fractions
