Base Temperature
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.
Pressure Input
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
assigned to
Pressure, Slot 1
appears as an option at the above
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.
Base Pressure
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.
