AMS Intelligent Device Managerprovides a simplified screen flow and procedures for how to respond to the diagnostic Flowmeter SizingSelecting the appropriate sensor size is an important step when considering a Magnetic Flowmeter . The physical properties of theprocess fluid, as well as the fluid velocity should be considered.

6 It may be necessary to select a flow sensor that is larger or smallerthan the adjacent piping to ensure the fluid velocity is in the recommended flow range for the application. Operation outside these guidelines may also give acceptable 3: Sizing guidelinesApplicationVelocity range (ft/s)Velocity range (m/s)Normal Service0 390 12 Preferred Service2 outside these guidelines may also give acceptable convert flow rate to velocity, use the appropriate factor listed in Table 4 and the following equation:Velocity =Flow RateFactor(1) Available with HART output : English unitsExample: SI unitsMagmeter Size: 4 in.

Five pipe diameters (upstream)B. Two pipe diameters (downstream)C. Flow directionInstallations with reduced upstream and downstream straight runs are possible. In reduced straight run installations, the metermay not meet accuracy specifications. Reported flow rates will still be highly groundingA reliable ground path is required between the sensor and the process fluid. Optional grounding rings or process referenceelectrodes are available with the sensor to ensure proper grounding.

9 See Table 5 and Table InformationRosemount 8750W Magnetic Flowmeter PlatformThe Rosemount 8750W Magnetic Flowmeter is available in a flanged sensor design. The sensors arefabricated from stainless and carbon steel and welded to provide a sealed coil housing that protectsagainst moisture or other contaminants. Sizes range from 1/2-in. (15 mm) to 48-in. (1200 mm). Thefield mount transmitter has a die cast aluminum housing for excellent reliability. The wall mounttransmitter features an easy to use operator interface.
