Ultimate Corrosion Defense (C22): The Nickel Alloy C22 wetted parts offer superior resistance to pitting, stress corrosion cracking, and aggressive oxidizing/reducing environments, far exceeding 316L stainless steel.
Exceptional Measurement Sensitivity: The ELITE design provides the highest turndown ratio in the industry, maintaining extreme accuracy (±0.05%) even as flow rates fluctuate significantly in large 6-inch lines.
Smart Meter Verification (SMV): Large-bore meters are difficult and expensive to remove for calibration. SMV allows you to verify the CMF400H’s structural integrity and electronic health in-line, in under 90 seconds.
Unmatched Immunity: Engineered to be immune to fluid, process, and environmental effects. Whether handling entrained gas, high-viscosity slurries, or high-vibration environments, the CMF400H remains stable.
Custody Transfer Grade: Fully certified for legal metrology and bulk fiscal transfer. One CMF400H can replace complex PD meter banks, reducing maintenance and pressure drop.
Wide Thermal Scalability: From cryogenic LNG service at -240°C to hot oil/bitumen at 350°C, this sensor maintains peak performance across the widest temperature envelope.
Advanced Transmitter Pairing: Optimized for the Emerson 5700 transmitter, offering high-speed processing and on-board data logging for auditing.
Digital Ecosystem: Seamless integration via HART, Modbus, PROFINET, and EtherNet/IP.
Global Safety Compliance: Rated for the harshest hazardous areas (Class 1 Div 1, ATEX Zone 0) and marine-certified for offshore platforms.
The Challenge: A chemical terminal needed to load large volumes of concentrated corrosive acid into tankers. They required a 4-inch meter that could handle the high-pressure surges of bulk pumps and resist chemical attack.
The Hanyu Solution: The facility implemented the Micro Motion CMF400H from
The Result: The Nickel Alloy C22 construction prevented any corrosion. The ELITE precision ensured that billing discrepancies were reduced to near zero.
The Impact: The facility realized a ±0.05% accuracy, saving thousands of dollars per shipment in "lost" product and reducing maintenance downtime by 85%.
Q: Why choose the CMF400H over the stainless steel CMF400S?
A: Use the CMF400H if your fluid contains chlorides, sulfuric acid, or other chemicals that cause pitting in stainless steel. The C22 alloy ensures the safety and longevity of your large-scale investment.
Q: Can this meter measure both Liquid and Gas?
A: Yes. The CMF400H is a multivariable powerhouse, providing industry-leading accuracy for liquids (±0.05%) and gases (±0.35%) simultaneously.
Q: Is it suitable for high-pressure hydrogen or CO2?
A: Yes, with pressure ratings available up to 6,000 psig, it is widely used in high-pressure gas carbon capture and storage (CCS) and large-scale industrial gas distribution.
Q4: How does Hanyu Zhilian ensure the quality of these large-bore sensors?
A: We provide 100% original Emerson/Micro Motion units with full Material Traceability Reports (MTRs) and original factory calibration certificates. Due to the weight and value of the CMF400H, we use specialized logistics and reinforced packaging. All project data is confidential.
