Rosemount™ 3051CFP Integral Orifice Flow Meter
Designed with an integral orifice primary element for easy installation, the Rosemount 3051CFP Integral Orifice Flow Meter is an industry-leading flow measurement solution.
This flow meter utilizes a self-centering integral orifice plate that is provided in a meter run and engineered to facilitate highly accurate flow measurement in small line sizes (0.5 - 1.5 in. or 15 - 40 mm). This flow meter is also leak-tested and calibrated to reduce leak points and increase process control.
