The Micro Motion ELITE CMFHC2Y is engineered for high-capacity applications where standard stainless steel fails. Constructed from Super Duplex Steel (UNS S32750), this 6-to-8 inch (DN150-DN200) sensor offers nearly twice the mechanical strength of 316L and exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking—especially in chloride-rich environments like brine and seawater.

Advanced Material Durability: Super Duplex Steel is specifically chosen for its ability to withstand aggressive chlorides and high-pressure fatigue, significantly extending sensor life in marine and offshore applications.
High-Capacity Fiscal Precision: Delivers a stable ±0.10% accuracy for large-volume bulk transfer, ensuring that high-value fluid measurement is consistent and legally defensible.
Smart Meter Verification (SMV): High-flow lines are difficult to isolate for service. SMV allows for a complete diagnostic of the sensor's health and tube integrity in under 90 seconds, while the meter remains in-line.
Process Noise Immunity: The ELITE balanced-tube design provides the highest immunity to environmental vibration and pressure pulsations, ensuring a stable zero point even in high-velocity bulk loading.
Secondary Containment Safety: Available with an optional rupture disk or purge fitting case, providing essential protection and pressure relief for hazardous or high-pressure fluid handling.
Advanced Transmitters: Pairs perfectly with the Emerson 5700 transmitter for high-speed signal processing, data historian capabilities, and intuitive diagnostics.
Digital Integration: Native support for HART, Modbus, PROFINET, and EtherNet/IP for seamless DCS integration.
Global Certifications: Fully certified for hazardous areas and marine bunkering (DNV, ABS, Lloyd's).
The Challenge: An oil and gas operator needed to measure corrosive produced water (high brine/chloride content) being re-injected at 145 bar in an 8-inch line. Previous 316L sensors suffered from pitting and required frequent recalibration due to high-pressure drift.
The Hanyu Solution: The operator upgraded to the Micro Motion ELITE CMFHC2Y from
The Result: The Super Duplex construction showed no signs of degradation after two years of continuous service. The meter maintained a stable ±0.10% accuracy regardless of the high operating pressure.
The Impact: The facility eliminated $50k in annual maintenance costs and improved reservoir management through more precise injection data. The SMV feature allowed them to meet regulatory compliance without removing the meter.
Q: Why choose Super Duplex (Y) over standard 316L Stainless Steel (M)?
A: Super Duplex is essential for high-pressure applications (up to 160 bar) and environments with high chloride levels (seawater, brine, sour gas) where 316L would be prone to pitting and failure.
Q: Can the CMFHC2Y handle gas measurement?
A: Yes. It provides ±0.35% accuracy for gases, making it ideal for large-scale, high-pressure natural gas headers or CO2 transport.
Q: Does it require straight pipe runs?
A: No. Like all Micro Motion Coriolis meters, it is independent of the flow profile, allowing for compact installation in offshore modules or pipeline manifolds.
Q4: How does Hanyu Zhilian ensure the quality of these large-bore sensors?
A: All CMFHC2Y units are supplied with original factory documentation, Material Traceability Reports (MTRs), and calibration certificates. We provide specialized logistics for these heavy assets. All project data is confidential per our Privacy Policy.
