property Table version number - This field displays the version number of the loaded prop-

erty table.

process Density - This field displays the process density. If “Property Table” is selected as

the “Density and Viscosity Source”, then the meter will calculate this value from the property

table based on the current process temperature and pressure. If “User Defined” is selected as

the “Density and Viscosity Source”, this field will be equal to the “User Defined Density” field. If

“Steam Table” is selected as the “Density and Viscosity Source”, then the meter will calculate

this value from the memory resident steam property table based on the current process tem-

perature and pressure. The unit for this field is lb/CuFt.

standard Density - This field displays the density calculated for the standard (or normalized)

conditions. The standard conditions, the base temperature and pressure, can be viewed and

set by the “Standard Flow” dialog box accessible from the “Configure Meter” pull-down menu.

The standard density value is used to calculate standard flow using the following equations:

Standard Flow = Actual Flow × Process Density

Standard Densiity

If “Property Table” or “Steam Table” is selected as the source for density and viscosity infor-

mation, then the standard density is determined from the property table using the standard

temperature and pressure values. If “User Defined” is selected as the source for density and

viscosity information, then standard density is calculated using the ideal gas law equations.

process viscosity - This field displays the process viscosity. If “Property Table” is selected as

the “Density and Viscosity Source”, then the meter will calculate this value from the property

table based on the current process temperature and pressure. If “User Defined” is selected as

the “Density and Viscosity Source”, this field will be equal to the “User Defined Viscosity” field.

If “Steam Table” is selected as the “Density and Viscosity Source”, then the meter will calculate

this value from the memory resident steam property table based on the current process tem-

perature and pressure. The unit for this field is Centipoise (cP).

NOTE: Save the changes to EEPROM and put the meter in-service after making changes.
