The Rosemount 3051SFP ProPlate differential pressure flow meter provides a complete volumetric flow measurement solution by incorporating the Rosemount 3051S pressure transmitter with a Rosemount ProPlate primary element producing a reliable, cost-effective flow measuring device that performs extraordinarily well in a variety of applications.

The Rosemount 3051SFP ProPlate differential pressure flow meter is highly effective in liquid flows and provides a cost-effective solution for uncompensated gas and steam flows. Reliability is improved by eliminating impulse lines, reducing the possibility of plugging or freezing. The special flange body and bolting design ensures the ProPlate flow meter is centered in the pipe. This unique design practically eliminates the potential for misalignment errors, which are common when traditional orifice plate technology is applied to small line sizes.

Components of the Rosemount 3051SFP ProPlate Differential Pressure Flow Meter:

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.

ProPlate Primary Flow Elements

Rosemount ProPlate elements are manufactured to meet AGA, ASME, ISO and DIN standards. A number of elements are available to suit particular application needs:
