Roxar™ Watercut Meters
Inline, field–mounted Roxar Watercut Meters use sensitive, microwave–resonance technology to accurately measure the permittivity of oil/water mixtures in real– time. The full–bore meters improve wellhead efficiencies, separation processes, custody transfers and fiscal reporting, and can be easily adjusted for salinity and changing dry–oil densities.

  • Accurately measure the permittivity of oil/water mixtures with patented microwave-resonance technology
  • Automatically compensate for the salt content in the water fraction with an AutoSalinity function
  • Compensate for changes in fluid density in real time with an AutoZero feature
  • Achieve a robust and stable measurement principle with a full-bore, inline solution
  • Cover a high range of flow conditions - salinity, density, temperature, etc.
