Extreme Material Integrity: The C22 Nickel Alloy flow path is designed to withstand aggressive acids (sulfuric, hydrochloric, nitric) and chlorides, where standard stainless steel fails.
Unparalleled Sensitivity: The ELITE series design offers the best-in-class turndown and zero stability, ensuring consistent measurement even during low-flow conditions or changing process pressures.
Smart Meter Verification (SMV): High-value chemicals require zero downtime. SMV allows you to verify the structural and electronic health of your CMF100H in-situ, providing an audit-ready report without ever opening the process line.
Exceptional Immunity: Engineered to be virtually immune to external vibration, piping stress, and temperature fluctuations, providing a stable "zero" point that you can trust.
Wide Range Scalability: Handles everything from cryogenic (-240°C) to extreme high heat (350°C) and pressures up to 2,465 psig, offering a single solution for a vast array of plant conditions.
Global Custody Transfer Approvals: Fully certified for fiscal measurement and legal-for-trade billing, ensuring absolute financial accuracy in high-value bulk transfers.
Multivariable Power: A single CMF100H replaces separate flow, density, and temperature transmitters, simplifying your piping and reducing leak points.
Advanced Electronics Pairing: Fully compatible with the Emerson 5700 transmitter for local data logging, graphical diagnostics, and fast signal processing.
Global Protocols: Native support for HART, Modbus, PROFINET, and EtherNet/IP ensures seamless integration into your existing DCS or PLC network.
The Challenge: A chemical plant needed to measure concentrated hydrochloric acid in a 1-inch line at 120 barg. Previous stainless steel meters suffered from rapid pitting and frequent calibration drift.
The Hanyu Solution: The plant upgraded to the Micro Motion CMF100H from
The Result: The Nickel Alloy C22 wetted parts showed zero degradation after 24 months of service. The ±0.05% accuracy significantly improved reaction consistency.
The Impact: Acid waste was reduced by 9%, and maintenance-related downtime was eliminated, providing a total return on investment in under a year.
Q: Is Nickel Alloy C22 significantly better than 316L Stainless Steel?
A: In corrosive environments containing chlorides or oxidizing acids, Nickel Alloy C22 is vastly superior. It prevents pitting and stress-corrosion cracking that can lead to catastrophic failure in 316L steel.
Q: Can I use the CMF100H for high-pressure gas measurement?
A: Yes. With a pressure rating of 2,465 psig (170 barg) and a gas accuracy of ±0.35%, it is ideal for corrosive gas distribution and specialty gas research.
Q: Is the CMF100H drainable?
A: While the CMF series is known for sensitivity, if a fully self-draining design is your primary requirement for vertical installation, we recommend also considering the CMFS100 series.
