Specifications and Reference Data
A.3 3051SF specifications
A.3.1 Performance specifications
Performance assumptions include: measured pipe I.D, transmitter is trimmed for optimum flow accuracy, and performance is
dependent on application parameters.
Dynamic performance
Table 3. MultiVariable Flow Performance - Flow Reference Accuracy (Measurement Type1)
(1)(2)
1. Measurement Types 2 - 4 assume that the unmeasured variables are constant. Additional uncertainty will depend on the variation in the
unmeasured variables.
2. Range 1 flowmeters experience an additional uncertainty up to 0.9%. Consult your Emerson Process Management Representative.

Table 4. Flow Performance - Flow Reference Accuracy (Measurement Type D)
(1)(2)(3)
1. For Measurement Types 5 - 7, refer to the Reference Accuracy specification for the 3051SMV with Measurement Type P.
2. These flow measurement accuracies assume a constant density, viscosity, and expansibility factor.
3. Range 1 flowmeters experience an additional uncertainty up to 0.9%. Consult your Emerson Process Management Representative for exact specifications.
