The Micro Motion ELITE CMF300B is the industry standard for high-temperature and corrosive flow measurement. This 3-inch (DN80) sensor is constructed from premium Nickel Alloy C22, offering exceptional resistance to aggressive chemical environments. Part of the ELITE "Peak Performance" family, the CMF300B delivers unrivaled mass flow and density accuracy, ensuring process stability even in the most challenging thermal conditions up to 662°F (350°C).
Extreme Temperature Versatility: Designed to handle a wide measurement range, from cryogenic -400°F (-240°C) up to searing 662°F (350°C).
Advanced Material Integrity: Nickel Alloy C22 construction provides maximum immunity to corrosion and fluid effects in high-stakes chemical applications.
Smart Meter Verification (SMV): Real-time, in-process diagnostic tool that verifies meter health and calibration without stopping your process.
Unparalleled Sensitivity: Unmatched stability and measurement confidence, regardless of process pressure or environmental noise.
Large Bore Efficiency: The 3-inch (DN80) line size is optimized for high-volume process streams, slurries, and gas applications.
Global Compliance: Fully certified with ATEX, IECEx, CSA, NEPSI, and SIL2/SIL3 for secure operation in hazardous areas worldwide.

Q1: What industries benefit most from the CMF300B Nickel Alloy C22?
A1: Industries such as oil and gas refining, specialty chemical processing, and power generation, where high-temperature acids or corrosive slurries are common, rely on the C22's durability.
Q2: Can the CMF300B handle custody transfer applications?
A2: Yes. The CMF300B carries multiple custody transfer approvals and provides the extreme repeatability (±0.05% for liquids) required for legal-for-trade billing.
Q3: Does the high-temperature model require special installation?
A3: While the CMF300B doesn't require straight pipe runs, for high-temperature service (above 200°C), specialized insulation and mounting considerations are recommended to protect electronics and ensure safety.
Q4: How does Smart Meter Verification help in extreme temperature service?
A4: Thermal stress can affect any sensor over time. SMV allows you to check for tube damage or coating build-up while the meter is still at operating temperature, preventing unscheduled shutdowns.
