Key parameters
Measuring range
Annubar averaging pitot; line sizes from ~0.5–1.5 in. (product page) through larger Annubar platforms in PDS (2–96 in. family context); 150:1 rangedown on 3051 platform
Accuracy
Up to ±1.80% of flow rate at 8:1 turndown (Ranges 2–3)
Accuracy % FS
1.8
Output
4–20 mA HART; WirelessHART; FOUNDATION Fieldbus; flow + pressure via single pipe penetration
Supply
Per 3051C / WirelessHART SmartPower selection
Process connection
Annubar insertion / flanged mounting; factory assembled leak-tested meter
Fits averaging-pitot DP flow with a single pipe penetration where you need a Rosemount 3051CFA—Annubar T-shaped sensor integrated with a 3051 DP transmitter for liquid, gas, or steam, with HART and WirelessHART options.
Key advantages
- Primary — Annubar averaging pitot (T-shaped)
- Penetration — Single pipe insertion
- Fluids — Liquid, gas, steam
- Outputs — 4–20 mA HART; WirelessHART; Bluetooth options class
- Assembly — Integrated DP transmitter + Annubar
Typical applications
- Duct / large-pipe flow.
- Steam header metering.
- Retrofits wanting few penetrations.
Selection guide
- Pipe size / insertion length
- Protocol
- Material / pressure class
Common mistakes
- Insufficient upstream flow profile.
- Wrong insertion depth.
- Liquid service orientation errors.
When to RFQ / what to tell us
- Pipe size, fluid, protocol.
- Quantity, ship-to.
