Rosemount 3051CFA Annubar Flow Meter Technical Data and Engineering Selection Guide
Rosemount 3051CFA Annubar Flow Meter is supplied by SANTAN for industrial flow-measurement projects, replacement requirements and model-code review. The data below is intended for preliminary engineering selection and quotation preparation.
Verified Technical Specifications
| Model | Rosemount 3051CFA Annubar Flow Meter |
|---|---|
| Service | Gas, liquid and steam differential-pressure flow measurement |
| Primary element | T-shaped Annubar averaging pitot sensor |
| Published accuracy | Up to 1.8% of flow rate, application and configuration dependent |
| Line size | 2–96 in. (50–2,400 mm) |
| Assembly | Fully assembled and leak tested |
| Diagnostics / display | Plugged-impulse-line diagnostics, graphical display and Bluetooth are option dependent |
| Output / approvals | Select communication and safety options by complete transmitter order code |
These are product-family values, not a promise for every configuration. Final sizing, materials, approvals, accuracy, pressure and temperature limits must be confirmed against the complete manufacturer order code and current technical documentation.
Best-Fit Application
Choose 3051CFA when reduced permanent pressure loss and large-line insertion measurement are priorities. A verified sizing calculation still requires fluid properties, operating pressure/temperature, flow range, pipe schedule and straight-run data.
Quotation and Sizing Data Required
| Process | Fluid, phase, composition, conductivity/density/viscosity as applicable |
|---|---|
| Flow data | Minimum, normal and maximum flow; operating and reference conditions |
| Mechanical | Line size, schedule, connection standard, available straight run and orientation |
| Design limits | Operating/design pressure and temperature; wetted-material requirements |
| Electrical | Power, output/protocol, enclosure, hazardous-area and functional-safety requirements |
| Documentation | Required calibration, inspection, material and compliance documents |
