Emerson Rosemount 2051CFA Flow Meter

The Rosemount 2051CFA D L 060 D C H P S 2 T1 0 0 0 3 2A A 1A 3 and other variants in the series feature a unique averaging pitot tube design that creates a fixed separation point, optimizing differential pressure (DP) signal quality across an extended flow range. This patented design minimizes permanent pressure loss compared to traditional orifice plates, significantly reducing energy consumption and operational costs.With a flow turndown ratio of up to 100:1 (5:1 flow turndown), the Rosemount 2051CFA maintains exceptional measurement accuracy of ±2.30% of flow rate over its entire operating spanEmerson. Long-term stability is equally impressive, with a drift specification of ±0.125% of upper range limit (URL) over 5 years, ensuring consistent performance and reducing the frequency of calibration checksEmerson. The Rosemount 2051CFA S G 080 S A M T Q 5 E2 0 0 0 5 1B B 2B 5 model, specifically designed for steam applications, offers enhanced high-temperature tolerance up to 815°F (435°C), making it ideal for power generation and thermal processing plants

Technical Specifications and Versatility

The Rosemount 2051CFA series accommodates pipe sizes from 2 to 12 inches (50 to 300 mm), covering a wide spectrum of industrial process lines艾默生. The differential pressure measurement range extends up to 1000 inH2O (2.48 bar), providing flexibility for both low and high flow rate scenarios艾默生. Standard wetted components are constructed from 316 stainless steel (316 SST), ensuring excellent corrosion resistance for most chemical, oil and gas, and water treatment applicationsEmerson. For highly corrosive environments, the Rosemount 2051CFA E L 040 E B J P R 1 T5 0 0 0 2 5A A 3A 1 is available with Alloy C-276 or Tantalum options for superior chemical compatibility艾默生.A key strength of the Rosemount 2051CFA is its multi-protocol communication capability. Models like the Rosemount 2051CFA F G 100 F D N S T 3 Q1 0 0 0 4 3A A 2A 2 support 4-20 mA HART®, WirelessHART®, FOUNDATION™ Fieldbus, and PROFIBUS®Emerson. This interoperability allows seamless integration into modern distributed control systems (DCS) and enables remote monitoring, configuration, and diagnostics. The Rosemount 2051CFA X L 120 X C H P W 4 T0 0 0 0 1 2B B 1B 4 WirelessHART variant eliminates costly wiring, offering a battery-powered solution with up to 10 years of battery life and a wireless range of 225 meters (738 feet).

Safety, Certifications, and Ease of Use

Safety is paramount in industrial operations, and the Rosemount 2051CFA series is SIL 2/3 certified to IEC 61508 by an independent third party, making it suitable for safety instrumented systems (SIS)Emerson. It also holds NACE® certification for sour service environments and a full range of hazardous area approvals, including Class I, Division 1 and Zone 1 certifications, permitting installation in potentially explosive atmospheresEmerson.The Rosemount 2051CFA is equipped with a Local Operator Interface (LOI) for intuitive field configuration and diagnostics, simplifying commissioning and maintenance艾默生. Its direct-mount design reduces potential leak points and installation complexity, while the low-profile sensor minimizes flow disturbanceEmerson. The Rosemount 2051CFA comes standard with a 5-year limited warranty, reflecting Emerson’s confidence in its long-term durability and performanceEmerson.
