The Rosemount 3051MFA ProBar® differential pressure flow meter incorporates the exceptional performance of
the Rosemount 485 Annubar® primary element with the Rosemount 3095 multivariable 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 3095MFA is particularly effective with gas and steam applications.
By integrating pressure transmitter electronics with the primary element, the Rosemount 3095MFA 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 3095MFA ProBar® Differential Pressure Flow Meter include the following:
Rosemount 3095 Multivariable Pressure Transmitter
The Rosemount 3095 multivariable transmitter Accurately measures differential pressure, static pressure and
process temperature to dynamically calculate fully compensated mass flow. It is fully scalable and allows
users to customize performance, functionality, diagnostics, and connection systems depending upon the
application. The 3095 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.
