Roxar Multiphase
Salinity System
RMSS
Data Sheet
Roxar Multiphase Salinity System A new innovation from Roxar, the
pioneer in multiphase flow metering
Direct, continuous measurement of water
conductivity in a multiphase flow
Measuring conductivity / salinity of the produced water
from a well has become increasingly important as a key
operational parameter for many operators.
Key features
• Compact design, consists of a pipe spool and an
Exd flow computer mounted typically upstream of
the multiphase meter
• Stand-alone product based on modularity, allowing
integration with both new and existing multiphase
meters
• Real-time continuous outputs of both water
conductivity and salinity
• Low uncertainty and large operating range
Added Value for Customer
• Salinity independent multiphase measurement
• Formation water detection and break-through
monitoring
• Flow assurance, e.g. optimise corrosion,
erosion and scale inhibitors
• Reservoir management purposes e.g. maximise oil
production / minimise water coning
• Injected water monitoring
With the introduction of this product to the Roxar
portfolio, for those applications which demand high
accuracy, or are experiencing high watercuts and
unstable salinity, Roxar are able to offer the RMSS as
a solution to support and enhance the multiphase
measurement achieved by the Roxar Multiphase meter.
