Rosemount™ 3051SFC Compact Conditioning Orifice Plate Flow Meter
rosemount 3051sfc conditioning orifice plate flow meter
The Rosemount 3051SFC Compact Conditioning Orifice Plate Flow Meter is a no-equal solution for multivariable measurement, obtaining direct variable measurements in combinations of differential pressure, static pressure and process temperature.
This flow meter comes with a patented, 4-hole conditioning orifice plate for accurate measurement in turbulent flow conditions. This orifice plate also reduces pipe straight run, requiring only two pipe diameters (2D) upstream and downstream of the plate.
