The Micro Motion ELITE CMF200H (DN50) is a 2-inch Coriolis flow and density meter engineered for the world's most demanding fluid environments. By utilizing Nickel Alloy C22 (equivalent to Hastelloy®), this sensor provides exceptional resistance to pitting, stress corrosion cracking, and aggressive oxidizing/reducing media where stainless steel would fail.

Superior Corrosion Resistance (C22): Nickel Alloy C22 wetted components offer much broader protection than 316L stainless steel, specifically against fluids containing chlorides, solvents, and highly reactive chemicals.
Unrivaled Measurement Sensitivity: The ELITE architecture provides the best-in-class turndown ratio, allowing the CMF200H to maintain extreme precision even during significant flow rate fluctuations in 2-inch lines.
Smart Meter Verification (SMV): Gain real-time assurance of meter health without stopping your process. SMV checks the structural integrity of the C22 tubes and the electronic calibration in under 90 seconds.
Highest Immunity to Process Noise: Engineered with a unique design that is virtually immune to environmental vibrations and pressure variations, providing the most stable "zero" in the industry.
Widest Application Envelope: From cryogenic service (-240°C) for industrial gases to high-heat chemical reactors (350°C), the CMF200H adapts to your most extreme temperature requirements.
Custody Transfer Approval: Certified for bulk liquid and gas fiscal transfer, the CMF200H eliminates billing disputes and ensures regulatory compliance for global trade.
Advanced Digital Signal Processing: Powered by Micro Motion’s MVD (Multivariable Digital) technology for cleaner, faster, and more accurate data.
Transmitter Flexibility: Pairs seamlessly with the Emerson 5700, 2400, or 1700 transmitters to provide advanced diagnostics and local historian logging.
Universal Communication: Full support for HART, Modbus, PROFINET, and EtherNet/IP ensures easy integration into any modern DCS or PLC system.
The Challenge: A chemical refinery was experiencing frequent sensor failures in a 2-inch line dosing a chloride-rich additive. Pitting in 316L stainless steel meters led to dangerous leaks and expensive unscheduled downtime.
The Hanyu Solution: The refinery replaced the failed units with the Micro Motion CMF200H from
The Result: The Nickel Alloy C22 construction completely stopped the corrosion issues. The ELITE precision improved the dosing accuracy to ±0.05%.
The Impact: The refinery eliminated maintenance shutdowns for this line, saving over $50,000 annually in replacement costs and lost production time.
Q: Is Nickel Alloy C22 necessary for all corrosive applications?
A: While 316L is suitable for many fluids, Nickel Alloy C22 (CMF200H) is essential for media containing high levels of chlorides, organic acids, or oxidizing salts where stainless steel is prone to rapid pitting.
Q: Can the CMF200H handle entrained gas in liquids?
A: Yes. The ELITE series is renowned for its ability to handle "challenging" fluids, including slurries and liquids with minor gas bubbles, while maintaining stable measurement.
Q: Does it require straight pipe runs for installation?
A: No. Like all Micro Motion Coriolis meters, the CMF200H is independent of the flow profile, allowing for compact installation in tight spaces without upstream or downstream straight piping.
Q4: Why source the CMF200H from Hanyu Zhilian?
A: We supply 100% original Emerson/Micro Motion units with full Material Traceability Reports (MTRs) and original factory calibration certificates. All project inquiries are handled with strict technical confidentiality.
