Key parameters
Measuring range
DP ranges to 1000 inH2O (2.49 bar); static absolute to 3626 psia / gauge to 3626 psig; line sizes typically 2–96 in. (sensor size dependent)
Accuracy
Ultra for Flow ±0.80% of flow rate at 14:1 turndown (Annubar Ranges 2–3); Classic MV ±1.15% at 8:1
Accuracy % FS
0.8
Output
Mass/energy/volumetric flow, DP, static pressure, process temperature; 4–20 mA HART, WirelessHART, FOUNDATION Fieldbus
Supply
Per 3051S transmitter platform (loop-powered HART / Fieldbus / Wireless power module)
Process connection
Annubar mounting: Flange-Lok, Pak-Lok, Flo-Tap and flanged styles per model
Fits averaging-pitot DP flow where you need a Rosemount 3051SFA ProBar on liquids, gases or steam with ±0.80% of flow rate at 14:1 turndown (Ultra for Flow).
Key advantages
- Technology — Annubar averaging pitot + 3051S transmitter
- Media — Liquids, gases, steam
- Accuracy — ±0.80% of flow rate at 14:1 (Ultra for Flow)
- Turndown — 14:1 flow turndown class
- Install — Insertion / flo-tap style options per PDS
Typical applications
- Steam and gas header flow.
- Large-line liquids with low permanent pressure loss.
- Retrofit Annubar DP flow.
Selection guide
- Line size / probe — Annubar style
- Ultra for Flow — Accuracy option
- Material / flange — Process duty
- Transmitter protocol — HART/FF/PA
Common mistakes
- Wrong β / probe sizing for Reynolds.
- Ignoring straight-run needs.
- Steam duty without condensate awareness.
When to RFQ / what to tell us
- Line size, media, P/T, protocol.
- Quantity and ship-to.
