Product Description

Product Description

Emerson Micro Motion Coriolis CMF400 Density Flange-Mounted Flowmeter

The Emerson Micro Motion Coriolis Model CMF400 is a high-performance, flange-mounted density flowmeter designed to deliver precise and reliable measurement of mass flow, density, and temperature in a wide range of industrial applications. As part of Emerson's renowned Micro Motion Coriolis flowmeter family, the CMF400 combines advanced sensor technology with robust construction to meet the demanding requirements of process industries such as oil and gas, chemical processing, power generation, and food and beverage production. Its flange-mounted design ensures seamless integration into piping systems, offering ease of installation and long-term operational stability.

At the core of the CMF400's functionality is the Coriolis effect, a physical principle that enables direct measurement of mass flow by detecting the twisting motion induced in oscillating tubes as fluid passes through them. This technology eliminates the need for calibration adjustments due to changes in fluid properties, providing inherent accuracy across diverse operating conditions. The meter simultaneously measures fluid density by analyzing the natural vibration frequency of the tubes, while integrated temperature sensors compensate for thermal effects, ensuring consistent performance even in challenging environments. With a turndown ratio of up to 100:1, the CMF400 accommodates a broad range of flow rates without sacrificing precision, making it suitable for both high-volume and low-flow applications.

The CMF400 features a rugged, all-welded construction with process connections available in carbon steel, stainless steel, or other specialized alloys to withstand corrosive media and extreme temperatures. Its self-draining design minimizes material buildup, reducing maintenance needs and enhancing measurement reliability. The meter operates effectively across a temperature range of -200°C to 360°C (-328°F to 680°F) and supports pressures up to 420 bar (6,000 psi), depending on configuration. Advanced digital signal processing ensures immunity to vibration interference from adjacent equipment, a common challenge in industrial settings.

A key advantage of the CMF400 is its ability to provide multivariable measurement capabilities in a single device. By leveraging Coriolis technology, it delivers real-time data on mass flow rate, volumetric flow, fluid density, temperature, and totalized flow—all without the need for supplementary instrumentation. This integration simplifies process monitoring and control while reducing system complexity and lifecycle costs. The meter supports multiple communication protocols, including HART, FOUNDATION Fieldbus, and PROFIBUS, enabling seamless connectivity with control systems and asset management platforms. Optional built-in diagnostics provide predictive maintenance insights, alerting operators to potential issues such as coating buildup, corrosion, or abnormal operating conditions before they impact performance.

The CMF400 is engineered for minimal maintenance, with no moving parts subject to wear and a design that resists clogging or fouling. Its accuracy remains stable over time, eliminating the need for frequent recalibration typically required by inferential measurement technologies. The meter is available with hazardous area certifications, including ATEX, IECEx, and FM approvals, ensuring safe operation in explosive atmospheres. For hygienic applications, versions compliant with FDA and 3-A sanitary standards are also available.

Typical applications include custody transfer of hydrocarbons, blending and batching operations, multiphase flow measurement, and interface detection in pipelines. Its exceptional repeatability (±0.05% of reading) and linearity (±0.1% of rate) make it ideal for fiscal metering and inventory management tasks where precision is critical. In refining and petrochemical plants, the CMF400 reliably measures crude oil, refined fuels, lubricants, and solvents, while in chemical processing, it handles aggressive liquids like acids, solvents, and polymers with equal proficiency.
