About Factory Certificate Industries

Trusted by Chinaʼs Leading Energy Groups

In China, VNER has established long-term strategic partnerships with industry leaders Sinopec, CNOOC, and PetroChina, which collectively account for approximately 75% of the countryʼs total refining and petrochemical capacity.
Over the past three years, more than 20,000 units of VNERʼs flagship SA80T swirl flowmeter have been delivered. According to data from the China Instrument and Control Society and customer procurement records, VNER commands the leading position in Chinaʼs swirl flowmeter segment with an estimated market share of 60%68%, of which the SA80T model alone accounts for approximately 70% of installed units. Furthermore, VNERʼs swirl, vortex and electromagnetic flowmeters are widely deployed by the worldʼs top polysilicon producers, including Tongwei, GCL Technology, and Daqo New Energy.

  • Application
    Large-Diameter Acid Gas Measurement
  • Challenge
    Pipeline diameter: DN700 (low-pressure acid gas environment). Replacing an imported GE ultrasonic flow meter due to performance limitations
  • Solution:
    Collaborative pilot project using a customized vortex precession flow meter, tailored for on-site conditions.
  • Results:
    Wide turndown ratio to accommodate large flow variations. Real-time density and mass flow monitoring enabled. Successful delivery of the world's DN700 vortex precession flow meter.
  • Remarks:
    Operated in parallel with an imported ultrasonic flow meter for 2 years, demonstrating performance.
  • Advantages include
    High measurement accuracy (+0.5%)
    Fast response time (real-time data acquisition)
    Simplified maintenance (no periodic recalibration required).
    Energy efficiency (40% lower pressure loss compared to traditional devices). These benefits significantly improved production efficiency for the end-user and earned high praise from he clients.

  • Application
    Hydrogen Measurement in Reduction Furnaces
  • Challenge
    Measurement medium: Hydrogen gas with periodic operation cycles
  • Extreme flow range
    Requires accurate measurement of flow rates for integration into interlock control systems.Critical demands: Stability and high repeatability under dynamic conditions.
  • Solution
    Deployment of the Enhanced SA80T Vortex Precession Flow Meter.
  • Results
    Weak hydrogen signal detection: Achieved reliable measurement even at low Reynolds numbers (applicable to hydrogen's low density). Superior repeatability and stability: Outperformed mass flow meters in comparative testing.
  • Remarks
    Field validation: Demonstrated performance after 1 year of parallel operation with the existing
    Systems Industry adoption: Triggered large-scale implementation of vortex precession flowmeters in the polysilicon industry.
