Ultimate Material Durability: The C22 Nickel Alloy construction provides a robust defense against pitting, stress-corrosion cracking, and aggressive acids (like hot sulfuric or hydrochloric acid), ensuring a vastly extended service life.
High-Temperature Mastery: Engineered to maintain ±0.10% accuracy at temperatures up to 350°C (662°F), making it ideal for thermal oil systems and exothermic chemical reactions.
Elite Zero Stability: The unique sensor design offers the industry’s highest measurement sensitivity and unmatched zero stability, ensuring reliable data even as process conditions fluctuate.
Smart Meter Verification (SMV): High-pressure, corrosive lines are dangerous to open. SMV allows you to verify the sensor’s structural and electronic health in-situ without stopping the flow, providing a certified calibration report in minutes.
Superb Immunity: Virtually immune to pipeline vibrations, pressure shocks, and environmental noise, the CMF200B ensures a stable measurement "zero" point in the busiest plant environments.
High-Pressure Security: Rated for 190 barg (2,755 psig), this sensor offers a high safety margin for high-pressure injection and bulk transfer applications.
Multivariable Insight: Replaces separate transmitters for flow, density, and temperature with one DN50 device, reducing potential leak points in hazardous lines.
Advanced Transmitter Support: Pairs perfectly with the Emerson 5700 transmitter for graphical dashboards, historical data logging, and advanced diagnostics.
Digital Integration: Native support for HART, Modbus, PROFINET, and EtherNet/IP ensure the CMF200B fits seamlessly into your digital transformation strategy.
The Challenge: A refinery required precise mass flow measurement for a highly corrosive catalyst injected at 150 barg and 200°C. Standard stainless steel meters corroded within months, and pressure spikes caused frequent measurement errors.
The Hanyu Solution: The refinery implemented the Micro Motion CMF200B from
The Result: The Nickel Alloy C22 wetted parts showed zero signs of chemical attack after two years. The 190 barg rating handled pressure spikes effortlessly.
The Impact: Maintenance-related downtime was reduced by 95%, and the ±0.10% precision significantly improved fuel quality consistency.
Q: When should I choose the CMF200B (Nickel Alloy C22) over the CMF200A (316L Stainless Steel)?
A: Choose the CMF200B if your fluid contains chlorides, hot acids, or any media that causes pitting in stainless steel. The C22 alloy is essential for long-term safety and accuracy in aggressive chemical environments.
Q: Can this meter be used in cryogenic applications?
A: Yes. The ELITE series is rated down to -240°C (-400°F), making it a versatile choice for both extreme cryogenic liquids and high-temperature steam-jacketed lines.
Q: What are the custody transfer capabilities?
A: The CMF200B is globally certified for custody transfer and legal metrology, ensuring financial-grade accuracy for high-value chemical and fuel bulk transfers.
