Genuine OEM Product | Officially Authorized | The Top Choice for Large-Diameter Flow Measurement
I. Product Overview
The Rosemount 3051CFA is an integrated flow transmitter based on the differential pressure average velocity tube (Annubar) principle. Featuring a patented T-type probe design, it is specifically engineered for high-precision flow measurement of gases, liquids, and steam, offering low pressure drop, clog-resistant performance, and easy installation. It is suitable for large-diameter applications.
II. Key Performance Parameters
* Measurement Accuracy: 1.8% of flow reading (8:1 flow range ratio)
* Turndown Ratio: 150:1 (differential pressure) / 8:1 (flow)
* Measurement Range: Differential pressure up to 2.48 bar
* Applicable Pipe Sizes: DN50–DN2440 mm
* Media Temperature: -50–454°C
* Process Connections: Flange / Weld / Thread
* Protection Rating: IP67 / NEMA 4X
* Power Module: 10-year service life (wireless model)
* Warranty: 5-year limited warranty
III. Technical Advantages
1. Patented T-type Probe
Slotted pressure tapping design resists fouling and clogging; permanent pressure drop is significantly lower than that of orifice plates
Single probe simultaneously measures flow and process pressure
2. Exceptional Stability
10-year stability: 0.2% of full scale
Resistant to vibration, high temperatures, and corrosion
3. Intelligent Communication and Diagnostics
Supports 4–20 mA HART, Wireless HART, Fieldbus, and PROFIBUS PA
Built-in Power Advisory loop integrity diagnostics
Graphical backlit LCD with Bluetooth support for local configuration
4. Materials and Certifications
Wetted Materials: 316L SS / Hastelloy C-276
Explosion-Proof: ATEX, FM, CSA, IECEx
Functional Safety: SIL 2/3
Corrosion Resistance: NACE MR0175
IV. Typical Applications
* Energy & Power: Boiler steam, natural gas, cooling water
* Petrochemicals: Natural gas transmission, process gases, large-diameter liquids
* Metallurgy & Mining: Blast furnace gas, compressed air
* HVAC & Water Utilities: District heating, wastewater treatment, large-diameter water flow
