Unrivaled Bulk Precision: Delivers ±0.10% mass flow accuracy for large-scale transfers, significantly reducing "unaccounted-for" product loss in bulk logistics and terminal operations.
Extreme Temperature Versatility: Capable of measuring from cryogenic (-240°C) to extreme heat (350°C), allowing one sensor platform to handle everything from LNG to molten sulfur or heated bitumen.
Smart Meter Verification (SMV): Removing an 8-inch meter for calibration is an expensive logistical nightmare. SMV allows you to verify the CMFHC3A's health and calibration in-line in minutes, ensuring fiscal compliance without process interruption.
Custody Transfer Excellence: Fully certified for global fiscal measurement standards. Its superior repeatability (±0.05%) makes it the trusted choice for legal metrology and high-value custody transfer.
Maximum Uptime: With no moving parts to wear, clog, or replace, the CMFHC3A eliminates the maintenance overhead associated with large-scale turbine or positive displacement (PD) meters.
Secondary Containment: Features a robust pressure-rated sensor case as standard, providing an extra layer of safety for high-volume hazardous fluid applications.
Digital Intelligence: Pairs with the Emerson 5700 transmitter to provide advanced diagnostics, graphical dashboards, and historical data logging for audit trails.
Seamless Integration: Supports all major industrial protocols: HART, Modbus, PROFINET, and EtherNet/IP.
Marine & Offshore Ready: Carries comprehensive marine approvals, ideal for FPSO loading arms and barge bunkering stations.
The Challenge: A marine terminal was using mechanical PD meters for loading crude oil onto tankers. The meters required frequent recalibration and were prone to mechanical failure due to sand and paraffin in the oil.
The Hanyu Solution: The terminal installed the Micro Motion CMFHC3A from
The Result: The CMFHC3A handled the 8-inch flow with zero maintenance and provided a stable ±0.10% accuracy regardless of oil viscosity or entrained solids.
The Impact: Loading time was reduced due to lower pressure drop, and the terminal saved over $200,000 annually in maintenance costs and reduced measurement uncertainty.
Q: What is the main difference between CMFHC3 and standard CMF series?
A: The CMFHC3A is a "High Capacity" model specifically engineered with a larger flow path and reinforced structure to maintain high accuracy at the much higher velocities found in 8-10 inch pipelines.
Q: Can this meter be used for LNG (Cryogenic) service?
A: Yes. The CMFHC3A is rated down to -240°C, making it one of the few large-bore Coriolis meters globally capable of handling cryogenic bulk transfers with high precision.
Q: Is 316L Stainless Steel the only material available?
A: No. While 316L is standard, the CMFHC3 is also available in Super-Duplex for applications requiring even higher pressure ratings or superior resistance to stress corrosion cracking in saline environments.
Q4: Why source the CMFHC3A from Hanyu Zhilian?
A: We provide 100% original and brand-new Emerson products, accompanied by a complete documentation package including Material Traceability Reports (MTRs) and original Factory Calibration Certificates. For massive, safety-critical equipment like the CMFHC3A, we provide reinforced industrial export packaging and dedicated logistical support to ensure safe delivery of your high-value asset.
