The Rosemount CMF400 Mass Flowmeter represents the pinnacle of precision flow measurement technology, engineered to deliver unparalleled accuracy, reliability, and versatility across a broad spectrum of industrial applications. Designed by Emerson Electric Co., a global leader in automation solutions, this advanced flowmeter combines innovative Coriolis technology with robust construction to meet the demanding requirements of modern process industries.
At the core of the CMF400 lies its patented Coriolis flow measurement principle, which directly measures mass flow by inducing a vibration in the flow tube and detecting the resulting Coriolis forces. Unlike traditional flow measurement technologies that rely on indirect methods, such as differential pressure or velocity, Coriolis meters provide direct, highly accurate measurements of mass flow, density, and temperature. This makes the CMF400 ideal for applications where precise measurement of mass flow is critical, such as in chemical processing, oil and gas production, food and beverage manufacturing, and pharmaceutical applications.
The CMF400 features a compact, straight-tube design that minimizes pressure drop and eliminates potential areas for fluid accumulation, making it suitable for use with a wide range of fluids, including liquids, gases, and slurries. The meter's innovative sensor design ensures excellent resistance to wear, corrosion, and erosion, even in harsh operating environments. Additionally, the straight-tube configuration reduces the risk of clogging, making the CMF400 well-suited for applications involving viscous or particulate-laden fluids.
Features
One of the key advantages of the Rosemount CMF400 is its exceptional measurement accuracy. With a typical accuracy of ±0.10% for liquids and ±0.35% for gases, the CMF400 provides precise and repeatable measurements, even under varying process conditions. The meter also offers excellent density measurement accuracy of ±0.0005 g/cm³, making it ideal for applications requiring precise density monitoring, such as in custody transfer, blending operations, or process control.
The CMF400 is available in a wide range of sizes and configurations to accommodate various flow rates and process requirements. The meter can handle flow rates from as low as 0.05 kg/h to as high as 90,000 kg/h, making it suitable for both small-scale laboratory applications and large industrial processes. The meter's pressure ratings range from 10 bar to 400 bar, ensuring compatibility with a wide range of process pressures.
Product Overview
In addition to its exceptional measurement performance, the Rosemount CMF400 offers a range of advanced features and capabilities that enhance its functionality and usability. The meter is equipped with a state-of-the-art digital transmitter that provides real-time monitoring and control of the flow measurement process. The transmitter features a user-friendly interface with a large, backlit display that shows flow rate, totalized flow, density, temperature, and other process variables. The interface also allows for easy configuration and calibration of the meter, as well as access to diagnostic information and alarms.The CMF400 supports a variety of communication protocols, including 4-20 mA, HART, Modbus RTU, Foundation Fieldbus, and Profibus PA, enabling seamless integration with existing control systems and data acquisition devices. This flexibility allows the meter to be easily incorporated into new or existing process automation systems, providing real-time data for process optimization and control.
The CMF400 is designed to meet the highest standards of quality and reliability. The meter is manufactured in accordance with ISO 9001 quality management systems and undergoes rigorous testing and calibration before leaving the factory. The meter also complies with a variety of international standards and certifications, including ATEX, IECEx, FM, CSA, and CE, ensuring its suitability for use in hazardous environments.
