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.
