The Rosemount 2051CFA series is built on Emerson’s patented Coplanar™ platform. In this model, the transmitter, manifold, and flow element (orifice plate, venturi, pitot tube, etc.) are combined in a single assembly. ✔ Reduced installation time ✔ Lower risk of error ✔ Improved measurement reliability
The 2051CFA provides high accuracy and long-term stability in differential pressure-based flow measurement. It is widely used in EPC projects, OEM skid systems, and energy/petrochemical plants.

📑 Codes must be verified against the Emerson datasheet and selected according to process conditions.
Differential pressure is detected across the primary flow element.
The measurement is converted into a 4–20 mA HART or digital protocol signal.
The signal is transmitted to DCS/PLC systems for flow control.
Typical applications:
Steam, gas, and liquid flow measurement
Flow monitoring in power plants
Process optimization in petrochemical facilities
Compact flow solutions in OEM skid systems
⚡ Power plants → Steam and gas flow control
🛢️ Petrochemical & refinery → Flow measurement and process optimization
💧 Water & wastewater → Pipeline and tank flow monitoring
🔧 OEM skid systems → Integrated and cost-effective solutions
✔ Integrated transmitter + manifold + flow element in one assembly ✔ Compact and reliable solution ✔ Digital protocol support (HART, Fieldbus, PROFIBUS) ✔ Global certification compliance ✔ Cost advantage for EPC and OEM projects ✔ Fast RFQ support from Yeşil Grup Enerji
