1. Enter the base temperature and press Next Item/Enter. The ratio of
this value to the actual temperature is used to calculate the
standard mass flow rate.
2. Do one of the following:
If you selected No at Assume Saturation, proceed to Pressure
•
Input below.
If you selected Pressure as the Steam Input Type, proceed to
•
Pressure Input below.
If you selected Temperature as the Steam Input Type, proceed
•
to Base Pressure below.
1. Use the pull-down menu to select a fixed pressure value or to set
up the option card in Slot 1 that will supply the live pressure input
and press Next Item/Enter.
Note: If Slot 1 contains an activated option card with an input
Pressure, Slot 1
assigned to
prompt. If the process pressure is stable, a fixed value may be
used, but most applications require a live pressure input.
If there is no active option card for pressure, the meter
assumes you are using a fixed pressure.
2. Proceed to one of the following sections:
If you selected Fixed - proceed to Step 3.
•
If you selected Slot 1 - proceed to Step 4.
•
3. Enter the known fixed process pressure and press Next Item/
Enter. The meter will only accept values from 0 to 5000 psia.
Proceed to Base Pressure below.
4. Use the pull-down menu to set up input A or input B and press
Next Item/Enter. The inputs were labeled during setup.
Note: The set up of input A is used as an example. Identical
procedures would be used to set up input B.
Enter the base pressure and press Next Item/Enter. The ratio of this
value to the actual pressure is used to calculate the standard mass
flow rate.
