In high-volume liquid and gas transfer, precision translates directly into financial security. The Micro Motion ELITE CMFHC4M (DN250 to DN350) is the world’s most trusted high-capacity Coriolis meter. Engineered for the most demanding bulk measurement challenges, it delivers unparalleled accuracy and stability, making it the definitive choice for crude oil terminals, FPSOs, LNG bunkering, and large-scale chemical processing.
The CMFHC4M features a unique low-frequency sensor design that provides superior sensitivity even in 14-inch pipelines. Unlike ultrasonic or turbine meters, ELITE technology is immune to flow profile disturbances, viscosity changes, and density fluctuations. It delivers a consistent ±0.10% liquid mass accuracy, ensuring "fiscal-grade" precision for every drop of high-value fluid.
Recalibrating a 14-inch meter is a massive logistical undertaking. With integrated Smart Meter Verification (SMV), the CMFHC4M allows you to verify the sensor’s structural and electronic health in under 90 seconds—without stopping the flow or breaking the process seal. This real-time diagnostic tool provides a robust audit trail for custody transfer and safety compliance (SIL2/SIL3).

The CMFHC4M is built to withstand the harshest environments. Whether you are dealing with cryogenic LNG, high-temperature bitumen, or abrasive slurries, its 316L Stainless Steel construction ensures long-term reliability. Its high immunity to environmental vibration and process noise means you get stable readings even in the busiest loading terminals or offshore platforms.
A: The Micro Motion ELITE CMFHC4M delivers an industry-leading liquid mass and volume accuracy of ±0.10%. Its exceptional repeatability of ±0.05% makes it the global standard for high-capacity custody transfer and fiscal metering.
A: Yes. The CMFHC4M supports one of the widest process temperature ranges available, from cryogenic LNG at -400°F (-240°C) to high-heat applications up to 662°F (350°C), without compromising measurement stability.
A: No. Unlike ultrasonic or turbine meters, the CMFHC4M Coriolis meter is immune to flow profile disturbances and swirl. It can be installed in tight spaces or offshore skids without the need for long straight pipe runs or flow conditioners.
A: Smart Meter Verification allows you to verify the structural and electronic integrity of the DN250-DN350 sensor in under 90 seconds while the process is running. This eliminates the need to pull the meter out of service for routine calibration checks, maximizing uptime.
A: Yes, for highly corrosive or abrasive applications, the CMFHC4M is also available in Super-Duplex stainless steel, providing superior yield strength and resistance to pitting and stress corrosion cracking.
