The Rosemount™ 3051CFC is a compact differential pressure flow meter from Emerson, designed primarily for measuring the flow of gases, liquids, and steam. It is suitable for applications such as closed-loop control, general monitoring, and trade settlement.
Key Features
Utilizing differential pressure as the measurement principle, it integrates a differential pressure transmitter with an orifice plate or flow-balancing orifice plate as the primary element. It can be directly installed between existing raised-face flanges for rapid deployment.
Key Specifications
• Pipe Size: 0.5–12 inches (15–300 mm)
• Differential Pressure Range: Up to 1000 inH₂O (2.48 bar)
• Turndown Ratio: Up to 150:1 (flow turndown ratio 8:1)
• Output and Communication: 4–20 mA HART®, WirelessHART®, Foundation Fieldbus, PROFIBUS PA, 1–5 V Low-Power HART®
• Process Wetted Materials: 316L Stainless Steel
• Warranty: Up to 5-year limited warranty
• Diagnostics: Basic diagnostics, process alarms, loop integrity, and orifice tube blockage detection
Key Features
• Integrated assembly and leak testing reduce potential leak points by approximately 70%, minimizing installation effort
• Available with standard orifice plates or patented 4-hole flow-balancing orifice plates, both compatible with raised-face flange installation
• Supports WirelessHART®, offering lower deployment costs and data reliability >99%
• Features a backlit graphic display and an 8-language user interface, with Bluetooth support for rapid maintenance
• Complies with SIL 2/3 (IEC 61508), NACE®, and other certifications, suitable for hazardous locations
Common Applications
Suitable for measuring gas, liquid, and steam flow in industries such as chemicals, oil and gas, power, and energy, particularly in applications with limited space or requiring rapid retrofitting.
Selection Guidelines
• Specify the medium type, operating pressure/temperature, flow range, and pipe size
• Select wired/wireless communication and whether SIL functionality is required
• Confirm process material compatibility (316L is standard; customization available upon request)
• Match the orifice plate β-coefficient and accuracy class based on trade settlement or control accuracy requirements
