Rosemount™ 3051SFA/3051SFC/2051CFP Flow Meter

Flow Measurement is the process of measuring fluid in your plant or industry. You can measure flow through a variety of different devices such as Coriolis, differential pressure, vortex, magnetic, ultrasonic, turbine and positive displacement meters.

With over 30 years of engineering experience, Emerson offers a complete range of DP flow solutions, including factory-assembled flow meters. Rosemount™ and Daniel™ DP flow products offer best-in-class performance and innovative designs to maximize efficiency in a wide variety of applications.

Three essential elements are required to engineer a differential pressure flow meter. The primary element creates a pressure drop across the flow meter by introducing a restriction in the pipe, and this engineered restriction enables Bernoulli’s equation to be used for a flow rate calculation. The pressure drop is measured by a secondary element, a differential pressure transmitter, while tertiary elements consist of everything else within the system, such as impulse piping and connectors.
