High-Temperature Excellence: Specifically designed to maintain its ±0.10% accuracy in processes reaching up to 350°C (662°F), ensuring stable measurement where standard sensors fail.
Elite Measurement Sensitivity: The unique sensor geometry provides the industry’s best turndown ratio and zero stability, allowing for precise measurement across the widest flow range.
Smart Meter Verification (SMV): Eliminate the cost and danger of pulling a 2-inch meter from a high-temperature line. SMV allows you to verify the sensor's health and calibration in-process in less than 90 seconds.
Superior Environmental Immunity: Engineered to be virtually immune to pipe stress, vibration, and pressure fluctuations, ensuring your data remains reliable regardless of external conditions.
Custody Transfer Approved: Globally certified for fiscal billing and legal-for-trade applications, making it the trusted standard for high-value liquid and gas bulk transfers.
Scalable and Robust: Rated for pressures up to 1,580 psig (109 barg), with options for even higher pressure models, providing the durability needed for the most challenging industrial skids.
Multivariable Insight: Replaces multiple discrete instruments with a single DN50 device, reducing leak points and installation costs.
Advanced Transmitter Support: Pairs with the Emerson 5700 transmitter for local data logging, zero-stability diagnostics, and fast signal processing.
Universal Protocols: Native support for HART, Modbus, PROFINET, and EtherNet/IP ensure seamless integration into any modern DCS or PLC environment.
The Challenge: A petrochemical refinery needed to measure the mass flow of a reactive monomer at 280°C. Standard flow meters exhibited significant drift due to thermal expansion and vibration.
The Hanyu Solution: The refinery implemented the Micro Motion CMF200A from
The Result: The CMF200A’s high-temperature design handled the heat effortlessly, while its superior immunity to vibration eliminated the drift issues.
The Impact: Process yield was optimized by 4%, and the facility successfully moved to an "on-demand" calibration schedule using SMV, saving thousands in annual maintenance costs.
Q: Does the "High Temperature" model require special insulation?
A: While the sensor is built for heat, we recommend standard industrial insulation practices for the sensor body to ensure consistent process temperatures and personnel safety.
Q: Can the CMF200A be used for LNG (Cryogenic) service?
A: Yes. The ELITE series is rated down to -240°C (-400°F), making the CMF200A one of the most versatile 2-inch meters for both extreme heat and extreme cold.
Q: What is the difference between CMF200 and CMFS200?
A: The CMF200 is the traditional ELITE design optimized for maximum sensitivity and extreme temperature/pressure ranges. The CMFS200 is part of the "Elite Supreme" line, which features a more compact, self-draining design.
