Action

Enter the relevant flow process data from the Venturi Sizing Data Sheet into the appropriate entry fields on the Process Data page as follows:

Normal Flowrate	= 630 CFM
Normal DP	= 49 inches H2O @ 39.2 °F
Design Pressure	= 129.7 psia
Design Temperature	= 100°F
Standard Density	= 0.0764 lbs/ft3
Compensation Mode	= Full

You can change the engineering units by clicking on the text box with the right mouse button.

Click Next to proceed to the Flowing Variables page.

Click the following options for failsafe indication on the Flowing Variables page (so that there is an “a “in each check box):

aAbs. Pressure

aProcess Temp

This will ensure that the PV4 flow output will go to failsafe if either the static pressure or temperature sensors fail.

•Set Damping = 1.0 seconds.

Click Next to proceed to the Solutions page.

The calculated Kuser value appears on the Solutions page of the Kuser Model along with a list of items (with values) that you have configured from previous pages. Review the Wizard values to make sure they are correct.

Click Finish to complete the Kuser calculation procedure.

Connect SCT to SMV and establish communications. (See subsection 5.2 for procedure, if necessary.)

Perform Download of the database configuration file to the SMV.

Use the procedure in subsection 7.5, Using Transmitter to Simulate PV Input to verify the Kuser and flow calculation for this application. You can simulate inputs for PV1, PV2, and PV3 to verify PV4 output.
