The Micro Motion ELITE CMF300H is the definitive choice for high-capacity, peak-performance flow measurement. Engineered with Nickel Alloy C22 wetted parts, this 3-inch (DN80) sensor is designed to withstand the most aggressive chemical environments where standard stainless steel fails. Whether managing bulk acid transfers, large-scale refinery processes, or high-value custody transfer, the CMF300H delivers unmatched stability and an optional liquid mass accuracy of ±0.05%.
Ultimate Material Integrity: Nickel Alloy C22 construction offers best-in-class resistance to stress corrosion cracking and aggressive oxidizing media.
Unmatched Measurement Sensitivity: The ELITE series' unique design provides the highest immunity to vibration and process noise.
High-Pressure Capability: Safely handles process pressures up to 2,683 psig (185 barg), suitable for demanding industrial upstream and midstream tasks.
In-Process Integrity Assurance: Features Smart Meter Verification (SMV), allowing you to check meter health and tube integrity in real-time without stopping bulk flow.
Extreme Temperature Range: Performs reliably across a massive thermal window from -400°F to 662°F (-240°C to 350°C).
Comprehensive Certifications: Fully certified for hazardous areas (ATEX, IECEx, CSA) and safety-critical environments (SIL2/SIL3).

Q: Is the CMF300H suitable for Custody Transfer?
A: Yes. The CMF300H holds extensive custody transfer approvals including MID OIML R 117, NTEP, and Measurement Canada, combined with elite-level precision.
Q: How does Smart Meter Verification benefit a 3-inch installation?
A: For large-bore meters, removing the sensor for calibration is expensive and disruptive. SMV allows you to verify the meter's performance while it remains in the pipeline, ensuring bulk measurement remains accurate.
Q: What are the typical industries for the Nickel Alloy C22 version?
A: It is primarily used in chemical processing (strong acids), pharmaceutical bulk manufacturing, and oil and gas applications involving sour gas or corrosive brine.
