Rosemount 3051CF Flowmeters combine the proven Rosemount 3051 Pressure Transmitter and the latest primary element
technologies. All flowmeters are fully assembled, calibrated, configured, and leak tested for out-of-the-box installation and are available with wired or wireless capabilities to meet all of your application needs.

Rosemount 3051CFA Annubar Flowmeter
Rosemount Annubar technology minimizes permanent pressure loss while
delivering best in class accuracy.

• Lowest material costs for large line sizes
• Flo-tap enables installation without process shutdown
• Realize up to 96% less permanent pressure loss compared to traditional orifice plate installations

Rosemount 3051CFC Compact Conditioning Flowmeter
Rosemount Compact Conditioning technologies provide unprecedented
performance with minimal straight-run requirements. Solutions include
conditioning orifice plate or Annubar primary elements.

• Conditioning Orifice requires only two pipe diameters upstream and downstream
• Eliminate swirl and regular profiles resulting in more stable and accurate flow measurement
• Savings up to 55% when compared to a traditional orifice plate installation can be realized

Rosemount 3051CFP Integral Orifice Flowmeter
Rosemount Integral Orifice Flowmeters deliver highly accurate small-bore flow
measurement capability with minimal installation and maintenance
requirements.

• Best performance for small line sizes 1/2-in. (15 mm) to 11/2-in. (40 mm)
• Precision honed pipe section and tight machining tolerances deliver higher installed performance
• Reduces uncertainty by up to 5% compared to traditional orifice plate installation

The Rosemount 3051CFA Annubar Flowmeter utilizes the T-shaped sensor design that delivers
best in class accuracy and performance while meeting the needs of diverse process applications,
whether it is high accuracy for precision control or high strength for severe flow applications.
Main capabilities include:

• Up to 1.8% of flow rate accuracy
• Available in 2- to 96-in. (50 to 2400 mm) line sizes
• Fully assembled and leak tested for out-of-the-box installation
• Power advisory can proactively detect degraded electrical loop integrity issues (option codeDA0)
• LOI with straightforward menus and built-in configuration buttons (option codeM4)

Rosemount 3051CFC Compact Flowmeters provide a quick, reliable installation between
existing raised face flanges. Depending on yo
ur application needs, you can reduce energy
loss with the Compact Annubar or minimize straight run requirements with the
Conditioning Orifice.

• Up to 1.8% of flow rate accuracy
• Available in1/2- to 12-in. (15 to 300 mm) line sizes
• Fully assembled and leak tested for out-of-the-box installation
• Power advisory can proactively detect degraded electrical loop integrity issues(option code DA0)
• LOI with straightforward menus and built-in configuration buttons (option code M4)

measurement in small line sizes. Integral Orifice utilize precision honed pipe section for
increased accuracy and self-centering plate design to prevent alignment errors that
magnify measurement inaccuracies in small line sizes.
