PRIMARY_VALUE_TYPE 13 The primary value type is the type of measurement represented by the
primary value.
101 = Volumetric Flow
PROC_DENS_PLOT_LL 98 Process Density graph plot lower limit which is used in some host
graphical displays.
PROC_DENS_PLOT_UL 97 Process Density graph plot upper limit which is used in some host
graphical displays.
PROC_FLOW_PLOT_LL 102 Process Flow graph plot lower limit which is used in some host graphical
displays.
PROC_FLOW_PLOT_UL 101 Process Flow graph plot upper limit which is used in some host graphical
displays.
PROC_TEMP_DAMP 74 This parameter is the sampling period interval to smooth the process
temperature measurement using a first-order linear filter. Limits are 0.4
to 32 seconds.
PROC_TEMP_LL 96 Process Temperature graph plot lower limit which is used in some host
graphical displays.
PROC_TEMP_PLOT_UL 95 Process Temperature graph plot upper limit which is used in some host
graphical displays.
PROC_TEMP_RANGE 94 This parameter reports the measurement range of the process
temperature sensor (MTA model).
Upper sensor range = 427 °C
Lower sensor range = -50 °C
PROCESS_COMPRESSIBILITY 61 Process compressibility is the compressibility of the process fluid at the
process conditions of pressure and temperature. This value is used to
calculate the PROCESS_DENSITY_RATIO and is not limit checked.
PROCESS_DENSITY_RATIO 62 This parameter is the process density ratio used in the conversion to
standard cubic feet and normal cubic meters. The ratio can either be
entered directly or computed from configured base and process
conditions. If entered directly, the PROCESS_PRESSURE parameter will
change so that the PROCESS_DENSITY_RATIO computed value is the
same as the entered value.
PROCESS_FLUID 35 Process fluid is the type of fluid being measured, either gas/steam,
liquid, or temperature-compensated steam. Changing service type will
set the following to default values:
PV Range 100% Value
PV Range 0% Value
Sensor Range 100% Value
Low-Pass Code
Low-Flow Cutoff
Trigger level
0 = Uninitialized
1 = Liquid
2 = Gas/Steam
3 = TComp Sat Steam (Temperature compensated saturated steam) MTA
models only
PROCESS_PRESSURE 58 Process pressure is the operating pressure of the process fluid upon
which the PROCESS_DENSITY_RATIO is calculated.
PROCESS_PRESSURE_UNITS 60 The engineering units of process pressure:
1137 = bar (absolute)
1142 = pounds per square inch (absolute)
1545 = Megapascals (absolute)
1547 = Kilopascals (absolute)
1557 = Kilograms per square centimeter (absolute)
