The Micro Motion ELITE CMF350M (DN100) is the workhorse of high-capacity mass flow measurement. Designed for 4-inch lines, this sensor provides the industry-leading accuracy and stability that the ELITE series is known for, in a robust 316L Stainless Steel construction. It is engineered to handle the complexities of bulk fluid transfer, from aggressive chemicals to high-value hydrocarbons.

Unrivaled Accuracy for Large Volumes: Delivers fiscal-grade precision even in high-flow 4-inch lines, making it the benchmark for custody transfer and bulk material balancing.
Smart Meter Verification (SMV): In large-scale operations, stopping the flow for calibration is costly. SMV allows you to verify sensor health and tube integrity in-line, in under 90 seconds, without interrupting the process.
Dual-Tube Stability: The ELITE balanced-tube geometry offers superior immunity to pipeline vibration and external stress, ensuring a stable zero point even in high-velocity bulk loading.
Multivariable Measurement: One device provides direct mass flow, volume flow, density, and temperature, reducing the need for multiple instruments and minimizing leak points in your 4" piping.
Extreme Temperature Versatility: From cryogenic service at -240°C to high-temperature processing at 350°C, the CMF350M maintains peak performance across the widest thermal range.
Advanced Transmitter Support: Pairs with the Emerson 5700 for high-speed processing, or the 2400 for compact DIN-rail mounting.
Digital Infrastructure: Native support for HART, Modbus, PROFINET, and EtherNet/IP for seamless DCS/PLC integration.
Marine & Global Certification: Fully certified for hazardous areas and marine bunkering (DNV, ABS, etc.), suitable for global ship-to-shore operations.
The Challenge: A refinery needed to load high-value petroleum products into tankers via a 4-inch line. Traditional volumetric meters required constant manual correction for temperature and density, leading to significant billing discrepancies.
The Hanyu Solution: The refinery installed the Micro Motion ELITE CMF350M from
The Result: The CMF350M provided direct mass measurement, automatically compensating for density changes. Its ±0.05% accuracy eliminated measurement disputes.
The Impact: Loading efficiency increased by 15%, and the refinery saved over $120k annually by reducing billing uncertainty and maintenance costs associated with older mechanical meters.
Q: Why choose the CMF350M over a smaller meter for 4" lines?
A: The CMF350M is specifically sized for DN100 lines to provide the lowest pressure drop and highest measurement stability at bulk flow rates. Using a smaller meter would cause excessive pressure loss and potential cavitation.
Q: Can this handle 4-inch gas flow?
A: Yes. The CMF350M is highly effective for large-scale gas measurement with a stable accuracy of ±0.35%, ideal for high-pressure gas headers or CO2 transport.
Q: Is the 316L Stainless Steel version suitable for high-pressure service?
A: The CMF350M is rated up to 1,480 psig (102 barg). For applications requiring even higher pressure or extreme corrosion resistance (e.g., sour gas), we also offer Super Duplex or Nickel Alloy C22 versions.
Q4: How does Hanyu Zhilian support large-bore meter logistics?
A: We specialize in the global logistics of heavy industrial meters. Every CMF350M is shipped with original factory documentation, MTRs, and calibration certificates. All project data is confidential per our Privacy Policy.
