Rosemount™ 3051CFC Compact Conditioning Orifice Plate Flow Meter

Rosemount

Providing precise flow measurements, the Rosemount 3051CFC Compact Conditioning Orifice Plate Flow Meter is an industry-leading solution designed with a compact conditioning orifice plate. This conditioning plate has a patented 4-hole design which enables accurate measurement downstream of flow disturbances. This conditioning orifice plate also reduces pipe straight run, requiring only two pipe diameters (2D) upstream and downstream for installation in tight areas.
