The Micro Motion ELITE CMF300A is a high-performance 3-inch (DN80) Coriolis flow and density meter, engineered for the most demanding bulk flow applications. Constructed from 316L Stainless Steel, this "A" version is specifically designed for high-temperature service, maintaining exceptional ±0.10% liquid flow accuracy across an expansive thermal range. It is the premier choice for refinery feedstocks, high-temperature chemical processing, and large-scale custody transfer applications.
Extreme Temperature Capability: Expertly handles process fluids from cryogenic -400°F (-240°C) to searing 662°F (350°C).
Unmatched Measurement Stability: The uniquely designed ELITE sensor provides the highest immunity to fluid, process, and environmental noise.
Bulk Flow Precision: Delivers industry-leading density accuracy of ±0.0005 g/cm³, essential for concentration and high-value mass balance.
Real-Time Integrity Assurance: Includes Smart Meter Verification (SMV) to provide in-process assurance of meter health without removing the sensor from the line.
Maximum Safety & Reliability: Certified for hazardous areas (CSA, ATEX, IECEx, NEPSI) and safety-critical systems (SIL 2/3).
Custody Transfer Approved: Holds multiple fiscal measurement certifications for high-accuracy bulk loading and unloading.
Rugged Pressure Handling: Rated for maximum working pressures up to 1,730 psig (119 barg).

Q: How does the CMF300A handle high-viscosity fluids like bitumen or heavy oil?
A: The ELITE CMF300 series is designed with a low-pressure drop geometry and high sensitivity, making it highly effective for measuring viscous fluids even at elevated temperatures.
Q: Does the CMF300A require special insulation for high-temperature service?
A: Yes, for applications near 350°C, proper insulation and heat tracing (if necessary) are recommended to maintain consistent measurement and protect the transmitter electronics.
Q: Can I use the CMF300A for cryogenic applications?
A: Absolutely. The "A" model is versatile enough to handle cryogenic liquids down to -240°C, provided the correct transmitter and installation configuration are used.
