Roxar Multiphase Salinity System
The Roxar Multiphase Salinity System provides sensitive and real-time measurements of the conductivity and salinity of produced water in multiphase production wells.
Together with the Roxar Multiphase Meter, this enables operators to obtain saline independent multiphase measurements, take immediate remedial action to improve flow assurance (optimizing corrosion, erosion and scale inhibitors), minimize water coning, and maximize oil & gas production.

  • Real-time continuous outputs of water conductivity and salinity.
  • Low uncertainty (+/-0.5 abs Siemens/meter) and a large operating range for the enhancement of multiphase meter measurements.
  • Compact design consisting of pipe spool and flow computer mounted upstream of the meter for easy installation and flexibility.
  • Stand-alone product based on modularity, allowing integration with both new and existing multiphase meters.
