Roxar subsea Singlephase sensor
The Roxar subsea Singlephase sensor is an intrusive sensor for measuring the mass flow rate of fluids or gas on a continuous basis in a single phase flow. The measurement output from the subsea singlephase sensor is intended to enhance or replace traditional calculations based on choke settings. In multiphase flow this sensor measures the force of the flow and hence gives real-time information on changes in the process.

- Compact instrument measuring the mass flow rates of fluids and gas on a continuous basis.
- Measurements use Roxar’s well-proven Force technology.
- Unique compactness and cost effective solution
- Sensor is primarily for injection wells.
- Can be used in conjunction with flow assurance and well allocation applications.
- Accuracy, Multiphase flow +/- 10% flow force.
- Accuracy, Single phase flow +/- 5% flow force (after flow loop test characterisation)
- Also available combined with a Sand Erosion sensor (SEF)
