Vortex Separation Multiphase Flow Meters
Here is a single, clean description that keeps the core meaning but reads original and neutral, with no hyphens and no brand references:
This vortex separation multiphase flowmeter is designed primarily for single well measurement and testing in oilfield applications. It is capable of accurately measuring oil, gas and water with water content and gas content ranging from zero to one hundred percent, without the need for traditional three phase separation. The system provides online and real time monitoring, serving as an effective alternative to conventional test separators.
The device operates based on an integrated separation and measurement principle. By combining vertical swirling separation and horizontal sedimentation technology, gas and liquid phases are effectively separated and measured independently. Gas and liquid flow through dedicated pipelines equipped with precision metering instruments, while intelligent valve control manages discharge according to liquid level conditions inside the separator.
Its compact structure, lightweight design and ease of relocation allow it to be installed permanently at wellheads or metering stations for continuous production monitoring, or used as a mobile unit for production testing, exploration evaluation and short term well testing. Automated control and data processing enable stable operation, accurate measurement and real time data transmission, making it suitable for complex oilfield conditions including high gas content, variable flow rates and sand containing crude oil.
The system combines dual splitters, a weight-based measurement method, and a high-efficiency built-in cyclone separator to deliver accurate phase separation and reliable flow calculation. Key advantages include:
Broad measurement range adaptability
High accuracy and repeatability
Stable operation in complex field conditions
The meter has been validated through prototype testing and performance appraisal at recognized metrology institutes, meeting or exceeding the standards of similar international products. It is certified under Venezuelan national standards and is suitable for deployment in OPEC member operations.

Vortex separation multiphase flowmeters feature a compact and fully integrated design that incorporates advanced CMF measurement technology. The system includes a dedicated casing gas metering pipeline as well as a separate well washing fluid pipeline, allowing it to handle complex well conditions and varied production scenarios with accuracy and stability.
The entire measurement process is fully automated and controlled through a computer system, ensuring consistent operation and reliable data collection. The testing setup can also be integrated with RTU systems, enabling remote data transmission, monitoring, and control for unattended or remote oilfield operations.
Vortex separation multiphase flowmeters are widely applied in oilfield operations for single well production measurement and testing. They are suitable for continuous monitoring at wellheads or metering stations, providing real time data on oil, gas, and water production without the need for conventional test separators.
These systems are also used for mobile production testing, exploration evaluation, and well performance assessment in onshore and offshore oilfields. Their ability to operate reliably under varying flow conditions makes them suitable for high gas content wells, intermittent production wells, sand containing crude oil applications, and remote or unmanned oilfield installations.
