Elite Measurement Confidence: Delivers the industry's highest immunity to environmental effects (vibration, pressure, temperature), ensuring your bulk flow measurements remain stable and repeatable year after year.
Smart Meter Verification (SMV): Large meters are difficult to remove for calibration. SMV allows you to verify the CMF400M's structural and electronic health in-situ, providing an audit-ready calibration report without stopping the flow.
Superior Density Precision: With an optional density accuracy of ±0.0002 $g/cm^3$, it is ideal for concentration measurement and product quality monitoring in large-scale blending and refining.
Custody Transfer Certified: Carries full global approvals for legal metrology (MID, NTEP, Measurement Canada), ensuring the highest level of trust in fiscal billing and international trade.
Extremely Wide Operating Envelope: Capable of handling everything from cryogenic fluids (-240°C) to extreme high temperatures (350°C), providing unparalleled scalability across your facility.
Robust 316L Construction: The "M" model features high-grade stainless steel wetted parts, offering excellent durability for standard industrial liquids, slurries, and gases.
Multivariable Insight: Replaces separate flow, density, and temperature transmitters with one DN100/DN150 device.
Digital Excellence: Pairs with the Emerson 5700 transmitter for advanced diagnostics, high-speed signal processing, and easy integration into HART, Modbus, PROFINET, or EtherNet/IP networks.
Hazardous Area Mastery: Fully certified for Zone 0, Zone 1, and Class 1 Div 1 environments worldwide.
The Challenge: A marine terminal needed to upgrade its 4-inch loading lines to reduce measurement uncertainty during high-volume fuel transfers. The previous mechanical meters suffered from wear and required constant maintenance.
The Hanyu Solution: The terminal switched to the Micro Motion CMF400M from
The Result: The CMF400M provided a stable ±0.05% accuracy with no moving parts to maintain.
The Impact: Measurement "shrinkage" was reduced by 0.08%, saving the terminal hundreds of thousands of dollars annually, while SMV ensured continuous compliance with maritime trade regulations.
Q: Can the CMF400M handle slurries or fluids with entrained gas?
A: Yes. The ELITE series is renowned for its ability to handle "challenging" fluids. When paired with the 5700 transmitter, it utilizes advanced digital processing to maintain stability even in two-phase flow conditions.
Q: Is the CMF400M suitable for LNG (Cryogenic) service?
A: Absolutely. It is rated down to -240°C, making it a premier choice for large-scale cryogenic loading and unloading operations.
Q: Why choose the CMF400 over the F-Series for a 4-inch line?
A: While the F-Series is excellent, the ELITE CMF400 offers higher sensitivity, better zero stability, and far superior density accuracy, which are critical for fiscal measurement and custody transfer.
