The Micro Motion ELITE CMF400B is the ultimate large-bore (4-6 inch) Coriolis meter for high-capacity, high-stakes industrial applications. Constructed from premium Nickel Alloy C22, this sensor provides the highest level of corrosion resistance and measurement stability. Specifically designed for high-temperature service, the CMF400B delivers peak-performance mass flow and density measurement for challenging liquids, gases, and slurries in heavy industrial and refining processes.
Large-Bore Capacity: Optimized for high-volume process lines (DN100-DN150), providing ELITE-level accuracy for mass flow and density at scale.
Extreme Temperature Range: Engineered to operate reliably from cryogenic -400°F (-240°C) up to 662°F (350°C).
Advanced Nickel Alloy C22: Offers maximum immunity to chemical attack and stress corrosion cracking in aggressive fluid environments.
Unparalleled Sensitivity: Uniquely designed to provide the highest measurement stability even in the presence of process noise or vibration.
Smart Meter Verification (SMV): Gain real-time, in-process assurance of meter health and calibration integrity without stopping high-volume production.
Global Fiscal Compliance: Holds a wide range of custody transfer approvals, ensuring measurement confidence for legal-for-trade applications.

Q1: Why is the CMF400B used for large-scale refining?
A1: Refining often involves high-temperature hydrocarbons and corrosive catalysts. The CMF400B's 4-inch size and C22 material provide the durability and flow capacity needed for these critical primary process streams.
Q2: Does the CMF400B require straight pipe runs for installation?
A2: No. Like all ELITE meters, the CMF400B is unaffected by flow profile disturbances, meaning it can be installed virtually anywhere without the cost of flow conditioners or long straight runs.
Q3: Can it be used for SIL 2 and SIL 3 safety applications?
A3: Yes. The CMF400B is certified for use in safety-instrumented systems (SIS) with SIL 2 and SIL 3 ratings, ensuring high reliability in risk-critical environments.
Q4: How does Smart Meter Verification benefit 4-inch lines?
A4: Removing a 4-inch meter for calibration is a major logistical challenge. SMV allows you to verify the sensor's health while it is still in the line, significantly reducing downtime and labor costs for large-scale operations.
