Product Description
Rosemount™ CMF400M452N2BZEZZZZ Coriolis Mass Flow Meter
Precision Measurement for Demanding Industrial Applications
1. Product Overview
The Rosemount™ CMF400 series represents Emerson's flagship Coriolis mass flow technology, engineered for high-accuracy measurement of liquids and gases in critical processes. The model CMF400M452N2BZEZZZZ combines advanced sensor design with robust electronics to deliver ±0.10% mass flow accuracy and ±0.05% density accuracy, making it ideal for custody transfer, batching, and process control in industries such as oil and gas, chemical, and pharmaceuticals. Its all-welded stainless steel construction ensures long-term reliability in harsh environments.
Key advantages include:
Direct mass flow measurement without dependency on fluid properties.
Multi-parameter output: Mass flow, volume flow, density, temperature, and concentration.
HART 7®, FOUNDATION™ Fieldbus, or Modbus® protocols for seamless integration with control systems.

3. Design and Innovation
3.1 Sensor Technology
Twin-Tube Design: Utilizes U-shaped flow tubes with drive coils and pickoff sensors to detect phase shifts caused by Coriolis forces, enabling direct mass flow calculation.
Material Integrity: 316L stainless steel construction with PTFE lining (code N2) for corrosion resistance in aggressive fluids (e.g., acids, solvents).
Vibration Immunity: Advanced signal processing algorithms reject external vibrations, ensuring stability in turbulent applications.
3.2 Electronics (R-series Transmitter)
Micro-Motion® Elite Technology: Enhances signal resolution and diagnostics.
Backlit LCD Display: Configurable for real-time parameters (flow, density, temperature).
Diagnostic Suite: Includes Heartbeat Technology for predictive maintenance, detecting coating, erosion, or tube asymmetry.
3.3 Safety and Reliability
Ex d Certification (BZ): Compliant with hazardous area standards (Zone 1/21).
Wetted Parts Welding: Eliminates gaskets, reducing leak points and maintenance.

4. Applications
The CMF400M452N2BZEZZZZ excels in:
Custody Transfer: High accuracy (±0.10%) meets API/ASTM standards for fiscal metering.
Chemical Dosing: Precise batching of additives with ±0.05% repeatability.
Slurry and Viscous Fluids: PTFE lining prevents buildup in abrasive media (e.g., mining slurries).
LNG and Cryogenics: Maintains performance at -40°C with thermal compensation.
5. Installation and Configuration
5.1 Mounting Guidelines
Orientation: Works in any orientation; avoid air pockets in liquid applications.
Pipe Supports: Install within 3x pipe diameter of supports to minimize stress.
Grounding: Use dual grounding screws (<1 Ω impedance) for surge protection.
5.2 HART/Fieldbus Configuration
Guided Setup: Use Rosemount Radar Master (RRM) or AMS Device Manager for parameterization.
Calibration: Factory-calibrated; zero verification required on-site via transmitter menu.
