User Defined Pressure - This field allows the user to enter a constant process pressure.
However, this pressure is only used when “User Defined” is selected as the process pressure
source. The unit for this field is PSIG.
Pressure Reading for 4 mA Analog Input - This field is used to specify the lower range of
the analog pressure input. Enter the pressure value that is associated with 4 mA on the ana-
log pressure input. This information is required when an absolute pressure or gauge pressure
analog input is selected as the process pressure source. The unit for this field is interpreted as
PSIA when an absolute pressure gauge is selected as the process pressure source and PSIG
when a gauge pressure gauge is selected as the process pressure source.
Pressure Reading for 20 mA Analog Input - This field is used to specify the upper range of
the analog pressure input. Enter the pressure value that is associated with 20 mA on the ana-
log pressure input. This information is required when an absolute pressure or gauge pressure
analog input is selected as the process pressure source. The unit for this field is interpreted as
PSIA when an absolute pressure gauge is selected as the process pressure source and PSIG
when a gauge pressure gauge is selected as the process pressure source.
NOTE: Save the changes to EEPROM and put the meter in-service after making changes.
Density and viscosity
The process density and viscosity information can be accessed through the “Density and
Viscosity” dialog box. To bring up this box, click the “Configure Meter” pull-down menu on the
Main screen and then select “Density and Viscosity”.
The data displayed by this window is read from the meter when the window is opened and
when the user clicks the Read or Write buttons.
