Thermal Stability & Repeatability: The "A" series features specialized sensor geometry and electronics designed to handle extreme thermal cycling, preventing zero-point drift even as process temperatures fluctuate.
Large-Scale Fiscal Accuracy: Delivers world-leading ±0.10% accuracy in 4-inch lines, ensuring precise inventory control and billing for high-value high-temperature bulk fluids.
Smart Meter Verification (SMV): High-temperature lines are often dangerous to isolate. SMV allows you to verify the health and integrity of your CMF350A in-line, in under 90 seconds, without stopping the flow.
Integrated Temperature Measurement: Built-in RTD provides accurate process temperature data, allowing the meter to compensate for thermal expansion effects in real-time.
Immunity to Process Noise: The ELITE balanced-tube geometry isolates the measurement from pipeline vibration and high-velocity turbulence common in large piping systems.
Advanced Transmitters: Recommended with the Emerson 5700 for high-speed signal processing and enhanced diagnostics in extreme environments.
Digital Support: Native support for HART, Modbus, PROFINET, and EtherNet/IP.
Global Certifications: Fully certified for hazardous areas (Class 1 Div 1) and carries SIL2/3 capability for mission-critical safety systems.
The Challenge: A chemical plant needed to measure the mass flow of heat transfer oil at 280°C in a 4-inch header. Previous volumetric flowmeters failed due to density changes and mechanical wear caused by thermal expansion.
The Hanyu Solution: The plant upgraded to the Micro Motion ELITE CMF350A via
The Result: The CMF350A provided direct mass measurement, making density corrections irrelevant. The sensor tubes handled the high heat without any signs of fatigue.
The Impact: Heating efficiency was improved by 12% due to more precise oil distribution, and the plant eliminated annual recalibration shutdowns.
Q: What is the main difference between CMF350M and CMF350A?
A: The CMF350A is specifically configured for high-temperature service (up to 350°C), featuring enhanced materials and sensor design to handle thermal stress, whereas the "M" series is the standard industrial version.
Q: Can the CMF350A measure gas at high temperatures?
A: Yes. It maintains a stable gas mass flow accuracy of ±0.35%, making it ideal for high-temperature steam or process gas headers.
Q: Does it require straight pipe runs?
A: No. Like all Micro Motion Coriolis meters, it is independent of flow profiles, which is a major advantage in crowded high-temperature piping modules.
Q4: How does Hanyu Zhilian ensure the quality of high-temp sensors?
A: We provide 100% original factory units with full documentation, including Material Traceability Reports (MTRs) and high-temp calibration data. All project data is confidential per our Privacy Policy.
