been determined that the operator needs the flow output to go to
failsafe when there is either a pressure or temperature failure
(selecting Abs. Pressure and Process Temp. will assure this).


Since Flow Failsafe has been selected for a pressure or
temperature failure, the default values do not need to be set.
If failsafe for the flow output is not needed when a pressure or
temperature sensor fails, the default values for temperature and
pressure are used in the flow calculation and the flowrate
continues to be reported.

The Solutions page presents itemized columns representing the data
entered and the corresponding Wizard values that were calculated
from the Wizard table data. Many of these values are used inside the
SMV 3000 Multivariable Transmitter to compensate and calculate the
flow for your application. Review the data to make sure the correct
choices have been made based on your flow application.
Click Finish to complete the Flow Compensation Wizard.

application. You can simulate inputs for PV1, PV2, and PV3 to verify
PV4 output.
Example: Air
An engineer has specified a SMV 3000 Smart Multivariable Transmitter to dynamically compensate
and calculate the standard volumetric flowrate of air through a standard 304 SS orifice meter with
flange taps. The engineer has sized the orifice meter to produce a differential pressure of 10 inches
H2O at 175 standard cubic feet per minute (SCFM). The flowing pressure is 40 psia, the flowing
temperature is 60 degrees F, the flowing density is 0.2079 lbs/ft3, and the standard density if 0.0764
lbs/ft3.
The steps in Table 61 show how to configure the SMV to calculate the PV4 flow variable for this
application.
