The Micro Motion ELITE CMFHC3Y is the industry’s flagship high-capacity sensor, specifically engineered for the world’s most demanding bulk flow applications. Designed for line sizes from 8 to 10 inches (DN200-DN250), this sensor is constructed from Super Duplex Steel (UNS S32750), providing extraordinary strength and unparalleled resistance to pitting and crevice corrosion in chloride-rich environments, such as brine, seawater, and produced water.

Super Duplex Reliability: Super Duplex Steel offers nearly double the mechanical strength of 316L and superior resistance to Stress Corrosion Cracking (SCC), making it the only choice for high-pressure brine and marine environments.
Fiscal Precision for Bulk Flow: With a stable ±0.10% accuracy, the CMFHC3Y is world-leading for custody transfer of high-value crude or chemicals in large pipelines, ensuring zero billing disputes.
Smart Meter Verification (SMV): In 10-inch lines, downtime for calibration is not an option. SMV allows you to verify sensor health and tube integrity in-line, in under 90 seconds, without stopping the process.
Environmental Immunity: The ELITE balanced-tube geometry provides the highest immunity to pipeline vibration and external stress—common in large-scale pumping stations and offshore platforms.
Secondary Containment Options: Available with a rupture disk or purge fittings, providing an extra layer of safety for high-pressure or hazardous fluid applications.
Advanced Transmitters: Pair with the Emerson 5700 for high-speed signal processing, advanced historian logging, and easy-to-read graphical diagnostics.
Digital Infrastructure: Full support for HART, Modbus, PROFINET, and EtherNet/IP.
Marine Ready: Fully certified for ship-to-shore transfer, bunkering, and offshore production systems.
The Challenge: An offshore platform needed to measure the flow of high-pressure seawater/brine for injection into a 10-inch line. Traditional 316L meters were failing due to chloride pitting within 18 months, and accuracy was drifting under the 150 bar process pressure.
The Hanyu Solution: The plant upgraded to the Micro Motion ELITE CMFHC3Y from
The Result: The Super Duplex construction showed no signs of corrosion after 3 years. The meter maintained a stable ±0.10% accuracy despite the high operating pressure.
The Impact: The platform eliminated unplanned maintenance shutdowns for flowmeter repairs. Accurate injection rates improved oil recovery efficiency, and the SMV feature allowed for regulatory verification without removing the sensor.
Q: When should I choose Super Duplex (Y) over Stainless Steel (M)?
A: Choose Super Duplex (Y) if your process contains high concentrations of chlorides (seawater, brine) or if you require a higher pressure rating than standard 316L can provide in large line sizes.
Q: Does the CMFHC3Y require straight pipe runs?
A: No. All Micro Motion Coriolis meters are independent of the flow profile. This is a massive advantage in the limited space of offshore platforms or pipeline manifolds.
Q: Can this handle 10-inch line flow?
A: Yes, the CMFHC3Y is specifically designed for DN250 (10") applications, providing the lowest pressure drop and highest flow capacity in the ELITE family.
Q4: How does Hanyu Zhilian ensure safe delivery of such large equipment?
A: We specialize in the logistics of heavy-bore Coriolis meters. Every CMFHC3Y is shipped in reinforced, export-grade crating with full documentation, including Material Traceability (MTRs) and Factory Calibration Certificates. All project data is confidential per our Privacy Policy.
