Rosemount 405C Compact Conditioning Orifice Plate Primary Element

The Rosemount 405C Compact Conditioning Orifice Plate Primary Element offers a patented 4-hole design enabling accurate measurement in disturbed flow conditions. Unlike traditional plates, this conditioning orifice plate reduces pipe straight run, requiring only two pipe diameters (2D) upstream and downstream of the plate, providing a flexible and reliable metering solution. This orifice plate is compact, easy-to-install and features self-centering mechanisms for optimal accuracy
