Rosemount 3051SFA Annubar Flow Meter

Rosemount 3051SFA Annubar Flow Meter Product Name: Rosemount 3051SFA Flow Meter Model Code: 3051SFA Manufacturer: Emerson (Rosemount) The Rosemount 3051SFA Annubar Flow Meter is a differential pressure–based primary flow element integrated with a high-accuracy transmitter. It provides precise, reliable flow measurement for liquids, steam, and gases in industrial process applications. The integral orifice design reduces installation complexity and enhances long-term performance. The system combines the reliability of an orifice plate with the advanced Rosemount 3051SFA smart differential pressure transmitter, ensuring accurate flow measurement with minimal maintenance. This specification applies to the supply, calibration, testing, and delivery of the Rosemount 3051SFA Integral Orifice Flow Meter for use in process measurement applications requiring high accuracy, stability, and compliance with international flow metering standards. Applications of Rosemount 3051SFA Orifice Flow Meter Measurement of liquid, gas, and steam flow Custody transfer and fiscal metering (where approved) Refining, petrochemical, power, and process industries Clean and non-clean piping applications Pressurized and elevated temperature flow streams Standards & Compliance of Rosemount 3051SFA The meter shall comply with the following industry standards: ISO 5167 (Orifice Metering of Fluids) ASME B36.10/36.19 (Pipe Dimensions) ANSI/ASME B31.1 & B31.3 Process Piping Codes IEC/EN 60079 for hazardous area classification NAMUR NE 43/NE 107 SIL assessment (as applicable) Meter Components Transmitter Model: Rosemount 3051SFA Smart Differential Pressure Transmitter Measurement: Differential Pressure (DP) Output: 4–20 mA HART® compatible Enclosure: Weatherproof / Harsh Environment (IP66/67) Accuracy: Up to ±0.04% of calibrated span (typical) Primary Element Integral orifice meter body with integral taps Orifice plate material: Stainless Steel (316/316L) or customer specified alloy Configurations: Concentric or Eccentric per application requirements Flange rating and size per process pipe Taps & Installation Integral orifice design with factory-set upstream/downstream tap locations Minimizes field layout errors Reduces installation cost and piping requirements Technical Specifications of Rosemount 3051SFA Flow Meter Parameter Typical Value Flow Range Application dependent (to be specified per process) Pipe Size Range DN25 – DN600 (1″ to 24″) Pressure Rating As specified by process conditions Maximum Operating Pressure Up to 413 bar (6000 psi) depending on materials Temperature Range –40°C to 400°C (–40°F to 752°F) depending on materials Wetted Materials SS316/316L, Hastelloy, Monel, Duplex, etc. Accuracy Up to ±0.04% of calibrated span Output Signal 4–20 mA HART® Approvals FM/CSA/ATEX/IECEx as required Performance Requirements Minimum measurable differential pressure resolution per user requirements Repeatability and stability for long-term operations Low susceptibility to flow profile distortion Configurable for single-phase and multi-phase flow where applicable Materials of Construction Wetted Parts Orifice plate: SS316/316L (standard) Meter body: Carbon steel / SS alloy (as specified) Sealing materials: PTFE / FKM per process compatibility Non-Wetted Parts Transmitter housing: Aluminum / Stainless Steel Mounting bracket: Carbon steel or SS Electrical & Instrumentation Power Supply: 12–36 VDC HART® 7 compatible Optional FOUNDATION™ Fieldbus / PROFIBUS PA Hazardous area options: Ex d, Ex ia, Ex n Documentation The supplier shall provide the following: Certificate of Conformance Material Test Reports (MTRs) Calibration certificates Installation & Maintenance Manual As-built drawing package Calibration sheet with zero/span data Testing & Calibration Supplier shall perform: 3-point calibration on DP transmitter Leak test on orifice assembly Verification of signal output Witness testing (optional) Packaging & Delivery Packaged for export Corrosion protection applied Shipping weight and dimensions provided Delivery lead time confirmed Warranty Minimum 12 months from date of commissioning or 18 months from shipment, covering manufacturing defects and performance compliance.
