The Rosemount 3051SFA ProBar® differential pressure flow meter incorporates the exceptional performance of the Rosemount 485 Annubar® primary element with the Rosemount 3051S pressure transmitter producing a reliable, cost-effective flow measuring device that performs extraordinarily well in a variety of applications.
Differential pressure (DP) flow meters utilize a primary element that operates by sensing an impact pressure and reference pressure through sensing ports and averaging them to get a flow measurement. The Rosemount 3051SFA is particularly effective with clean liquids.
By integrating pressure transmitter electronics with the primary element, the Rosemount 3051SFA ProBar® is a fully integrated flow meter that performs to the highest standards while providing installation flexibility, reducing costs and saving time.
Components of the Rosemount 3051SFA ProBar® Differential Pressure Flow Meter include the following:
Rosemount 3051S Multivariable Pressure Transmitter
The Rosemount 3051S transmitter enables pressure, temperature, and fully compensated mass and energy flow measurements. It is fully scalable and allows users to customize performance, functionality, diagnostics, and connection systems depending upon the application. The 3051S utilizes advanced software and functionality including a 4-20mA signal based on Hart® Communication or FOUNDATION™ fieldbus, user configured flow units, low flow cut-off, and process alerts for pressure and temperature.
Annubar® Primary Flow Elements
Rosemount Annubar primary elements feature a revolutionary shape to improve the accuracy and repeatability of every flow measurement point. Tight process control is gained by increased signal strength and reduced signal noise. Real-time mass flow measurements are available with the integral temperature sensor design. The patented T-shaped sensor includes a sealed, pressure-retaining thermowell that permits mass flow in all line sizes with a single pipe penetration.
There are two Annubar® primary elements available. The 285 Annubar® is a basic primary element suited for general purpose applications. The 285 has a basic accuracy of ±1.0% and is available in a duct mount version. The 485 Annubar® has a higher accuracy (±0.75%) and is available with more custom options including materials and surface finishes for applications with a high Reynolds Number.
