⚙️ Emerson Rosemount 2051CFA Coplanar Flow Assembly \| Technical Guide, Model Codes and Price Advantage
Reliable Integrated Flow Measurement
The Rosemount 2051CFA series is built on Emerson’s patented Coplanar™ platform. In this model, the transmitter, manifold and primary flow element (orifice plate, venturi, pitot tube, etc.) are delivered as a single assembly. This reduces installation time, minimizes error risk and increases measurement reliability.
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.
Model Code Explanation
- CFA (Coplanar Flow Assembly): Transmitter + manifold + primary flow element integration for flow measurement
- Pressure ranges: Wide differential pressure ranges depending on the flow element
- Process connections: ANSI/DIN flanges or threaded NPT connections
- Output: 4–20 mA HART; optional FOUNDATION Fieldbus, PROFIBUS PA
- Housing: Aluminum, stainless steel, polyurethane‑coated options
- Diaphragm materials: 316L SS, Hastelloy, Monel, Tantalum
- Certifications: ATEX, IECEx, FM, CSA approvals
