Configuration

Figure 3-39. Square root output transition point

Figure 3-39 only applies to the square root output for the 3051S MultiVariable with the Direct

Process Variable Output Feature Board.

Note

For a flow turndown of greater than 10:1, it is not recommended to perform a square root

transfer function in the transmitter. Instead, perform the square root transfer function in the

control system.

3.8 Menu trees and 475 fast keys

Based on the configuration ordered, some measurements (i.e. static pressure, process

temperature) and/or calculation types (i.e. mass, volumetric, and energy flow) may not be

available for all fluid types. Available measurements and/or calculation types are determined by

the MultiVariable Type and Measurement Type codes ordered. See “Ordering information” on

page 27 for more information.

The Menu Trees and 475 Fast Keys in this section are shown for the following model codes:

 MultiVariable Type M (Fully Compensated Mass and Energy Flow) with Measurement

Type 1 (Differential Pressure, Static Pressure, and Process Temperature)

 MultiVariable Type P (Direct Process Variable Output) with Measurement Type 1

(Differential Pressure, Static Pressure, and Process Temperature).

The Menu Trees and 475 Fast Keys for other model codes will vary.
