As part of Emerson's industry-leading portfolio of process instrumentation, this device integrates cutting-edge sensor technology with robust construction to deliver reliable and accurate flow data across diverse industries, including oil and gas, chemical processing, power generation, and water treatment. The 3051CF utilizes a differential pressure measurement principle, enabling it to work seamlessly with primary flow elements such as orifice plates, venturi tubes, and flow nozzles. Its modular design supports a wide range of process connections, materials, and output options, ensuring compatibility with existing systems while adhering to global safety and performance standards. Engineered for longevity, the device features exceptional stability over time, minimizing calibration requirements and reducing total cost of ownership.
The 3051CF stands out for its unparalleled measurement accuracy (±0.04% of calibrated span) and industry-leading turndown ratio of 200:1, enabling precise flow monitoring across extreme operating ranges. Its advanced Sensor Technology incorporates a silicon piezoresistive sensor with patented oil-filled isolation systems, providing immunity to vibration, temperature fluctuations, and process overpressure conditions up to 2300 psi. The transmitter boasts a response time of 90 milliseconds, making it suitable for dynamic flow control applications. With dual-compartment, hermetically sealed electronics housing rated IP66/IP67/NEMA 4X, the device excels in harsh environments while maintaining compliance with ATEX, IECEx, and SIL 2/3 safety certifications. The intuitive Local Operator Interface (LOI) with push-button configuration and LCD display simplifies commissioning, while its compatibility with HART®, FOUNDATION Fieldbus, and Profibus protocols ensures seamless integration into digital automation architectures.
Designed for versatile deployment, the Rosemount 3051CF supports liquid, gas, and steam flow measurement with optional multi-variable capability that combines DP, static pressure, and temperature sensing. Its advanced diagnostics package includes plug-and-play Metered Flow Calculations (MFC) that automatically detect installation errors and process anomalies. The SuperModule™ architecture allows for complete electronics replacement without process shutdown, significantly reducing maintenance downtime. Specialized versions are available for cryogenic applications (-320°F to 257°F), high-static line pressure conditions, and sanitary processes meeting 3-A standards. Backed by Emerson's global support network and a 15-year stability warranty, the 3051CF represents the gold standard in flow measurement technology, delivering unmatched reliability for critical process monitoring and custody transfer applications worldwide.

Packaging Advantages of Rosemount Flow Meters
Rosemount flow meters are designed with precision engineering, and their packaging reflects the same commitment to quality and reliability. The packaging solutions are tailored to protect sensitive components from physical damage, environmental factors, and electrostatic discharge during transit. Each flow meter is encased in anti-static, shock-absorbent materials that cushion against impacts, vibrations, and sudden movements. Customized foam inserts and rigid thermoplastic casings ensure that internal components, such as sensors and electronic modules, remain securely in place. Additionally, moisture-resistant barriers and desiccant packets are integrated to prevent corrosion or humidity-related damage, particularly critical for devices shipped to regions with extreme climatic conditions. The packaging is also designed for ease of handling, with ergonomic grips and clear labeling that includes handling instructions, compliance certifications (e.g., ISTA testing standards), and hazard warnings. This meticulous approach minimizes the risk of in-transit damage, reduces warranty claims, and ensures the product arrives in optimal condition, ready for installation.
Sustainability and Cost-Effectiveness in Packaging and Shipping
Rosemount prioritizes sustainability without compromising protection. The packaging materials are increasingly sourced from recycled or biodegradable alternatives, aligning with global environmental standards and reducing the carbon footprint. Lightweight yet durable materials lower overall shipping weight, cutting fuel consumption and emissions. Reusable packaging options are available for bulk orders, encouraging circular economy practices among industrial clients. From a cost perspective, Rosemount's optimized packaging design reduces material waste and freight expenses, savings that are often passed on to customers. The company also employs predictive analytics to anticipate shipping disruptions, such as weather events or port delays, enabling proactive rerouting and cost avoidance. Insurance-backed shipping programs further mitigate financial risks associated with rare transit incidents. By combining eco-conscious practices with lean logistics, Rosemount delivers a competitive edge-ensuring reliable delivery, lowering total cost of ownership, and supporting customers' sustainability goals. This holistic approach reinforces Rosemount's reputation as a leader in both technological innovation and responsible supply chain management.
