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. (Refer
to the SCT manual #34-CT-10-08 for procedure, if
necessary.)

Use the procedure in section
for this application. You can simulate inputs for PV1, PV2, and PV3 to
verify PV4 output.
Standard Flow Equation,
Example:
Superheated Steam Using an Averaging Pitot Tube
An engineer has specified a SMV 3000 Smart Multivariable Transmitter to compensate for steam
density changes and to calculate the mass flowrate of superheated steam using an averaging pitot
tube. The engineer has sized the averaging pitot tube to produce a differential pressure of 13.21
inches H2O at 45,000 lb/hr. The flowing pressure is 294.7 psia, flowing temperature is 590 degrees F,
and flowing density is 0.49659 lbs/ft3.
The steps in Table 60 show how to configure the SMV to calculate the PV4 flow variable for this
application.
