The Micro Motion ELITE CMFS015H (DN3) is the ultimate solution for critical low-flow applications where standard stainless steel fails. Constructed with Nickel Alloy C22 (Hastelloy equivalent) wetted parts, this 1/6-inch sensor is engineered to withstand highly corrosive acids, chlorides, and sour gas while maintaining laboratory-grade accuracy.

Unrivaled Corrosion Resistance: Nickel Alloy C22 provides a far superior defense against pitting and crevice corrosion in harsh media like wet chlorine or sulfuric acid compared to 316L stainless steel.
Extreme High Pressure Mastery: Rated for 6,000 psig (414 barg), it is specifically designed for subsea and offshore chemical injection skids where precision at high pressure is non-negotiable.
Self-Draining Design: The S-Series curved tube design allows for complete gravity-driven drainage. This minimizes waste of expensive catalysts and ensures safe flushing in corrosive service.
Smart Meter Verification (SMV): Verify your meter’s health and tube integrity in under 90 seconds without stopping the flow. SMV provides a certified diagnostic report while the meter remains in-line.
Multivariable Micro-Measurement: Simultaneously capture mass flow, density, and temperature. This eliminates the need for multiple sensors, reducing potential leak points in high-pressure lines.
Advanced Electronics: Pairs with Emerson 5700 or 2400 transmitters for high-speed signal processing and extensive data historian logging.
Digital Protocols: Full support for HART, Modbus, PROFINET, and EtherNet/IP for seamless integration into DCS/PLC systems.
Environmental Immunity: Designed to cancel out pipeline vibration and process noise, providing a stable zero point even at micro-flow rates.
The Challenge: A specialized chemical plant needed to inject a highly corrosive catalyst at 350 barg in a DN3 line. Previous sensors suffered from chloride pitting within months and lacked the precision needed for expensive additive control.
The Hanyu Solution: The plant implemented the Micro Motion ELITE CMFS015H from
The Result: The Nickel Alloy C22 construction showed zero degradation after 18 months of continuous service. The meter provided a stable ±0.05% accuracy despite the extreme pressure.
The Impact: Catalyst waste was reduced by 15%, and unplanned maintenance shutdowns were eliminated. The drainable design allowed for rapid, safe flushing during product changeovers.
Q: Why choose Nickel Alloy C22 (H) over 316L Stainless Steel (M)?
A: C22 is essential if your fluid contains chlorides or oxidizing acids. It prevents pitting and stress corrosion cracking that can cause catastrophic failure in standard 316L meters.
Q: Can the CMFS015H handle gas measurement?
A: Yes. It is a market leader for high-pressure gas dosing with an accuracy of ±0.25%, making it ideal for specialty gas blending and hydrogen applications.
Q: Does it require straight pipe runs for installation?
A: No. Like all Micro Motion Coriolis meters, it is independent of the flow profile and can be installed in tight dosing skids immediately following valves or bends.
Q4: How does Hanyu Zhilian support technical selection for high-pressure units?
A: We provide custom sizing reports (Sizing Reports) to ensure your pressure drop and accuracy targets are met. We guarantee 100% original factory quality with full material traceability (MTRs). All project data is confidential per our Privacy Policy.
