The Micro Motion ELITE CMF400A represents the pinnacle of large-bore Coriolis technology. Specifically engineered for line sizes between 4 and 6 inches (DN100-DN150), this 316L Stainless Steel sensor is optimized for high-temperature environments where maintaining accuracy is most difficult. Whether measuring hot hydrocarbons, heavy slurries, or high-pressure gases, the CMF400A provides the sensitivity and stability required for world-class process control.

Extreme Temperature Mastery: Designed to operate flawlessly from Cryogenic (-240°C) to High-Heat (350°C), making it the ideal choice for bitumen, hot oils, and LNG processing.
Bulk Transfer Reliability: In 4-6 inch lines, even small errors lead to massive inventory discrepancies. The CMF400A’s ±0.10% accuracy ensures fiscal-grade precision for large-scale distribution.
Smart Meter Verification (SMV): Verify your sensor's health and structural integrity without removing it from the line. In large-bore piping, this saves thousands in downtime and labor costs.
Superior Density Performance: Achieve a density accuracy of ±0.0005 $g/cm^3$ at high flow rates, allowing for real-time quality control of heavy fuels and complex slurries.
Unmatched Immunity: The ELITE balanced-tube design provides the highest immunity to pipeline vibration, pressure fluctuations, and environmental noise—common challenges in large industrial facilities.
The CMF400A is built for the smart factories of today:
Advanced Transmitters: Pair with the Emerson 5700 for high-speed signal processing, advanced historian logging, and easy-to-use graphical diagnostics.
Protocols: Full support for HART, Modbus, PROFINET, and EtherNet/IP.
Global Compliance: Certified for hazardous areas, marine environments (DNV/ABS), and custody transfer approvals.
The Challenge: A refinery needed to measure the flow of hot vacuum bottoms at 320°C in a 4-inch line. Traditional orifice plates suffered from heavy wear and drift, while other Coriolis meters couldn't handle the thermal expansion.
The Hanyu Solution: The refinery implemented the Micro Motion ELITE CMF400A from
The Result: The CMF400A maintained a stable ±0.10% accuracy despite the extreme temperature and high viscosity of the fluid.
The Impact: The refinery increased process efficiency by 8% due to more accurate mass balance. Maintenance interventions were reduced from once per month to once per year (routine verification only), significantly improving site safety.
Q: Can a 4-inch meter really handle a 6-inch line flow?
A: Yes. Depending on the flow rate and allowable pressure drop, the CMF400A is frequently used in 6-inch (DN150) lines where high-accuracy mass flow is required. Hanyu Zhilian provides sizing reports to ensure optimal performance.
Q: How does the "High Temperature" version differ from standard models?
A: High-temperature models feature specialized internal components and insulation to protect the sensor electronics and maintain calibration stability during extreme thermal expansion.
Q: Is 316L Stainless Steel suitable for heavy slurries?
A: 316L is very durable, but for highly abrasive slurries, we can consult on specialty liners or material options like Super-Duplex to extend the service life of your CMF400A.
Q4: How does Hanyu Zhilian support international shipping for such large sensors?
A: These sensors are significant capital assets. We provide reinforced export crating, handle all customs documentation, and include factory calibration certificates for every unit. All project data is kept confidential per our Privacy Policy.
