PRIMARY_VALUE is the value and status of Differential pressure/Gauge
pressure/Absolute pressure. PRIMARY_VALUE_RANGE is the limits of the
PRIMARY_VALUE, the units of the PRIMARY_VALUE (changing the units of the
value automatically changes the limits), and the decimal point position (number of
significant digits to the right of the point). The engineering units must match the units
selected in the parameter XD_SCALE of the Analog Input block that reads the channel
with this value.
SECONDARY_VALUE is the value and status of the meterbody temperature.
SECONDARY_VALUE_RANGE is the limits of the SECONDARY_VALUE, and it is
a read only parameter, while the units of the SECONDARY_VALUE can be changed as
desired (changing the units of the value automatically changes the limits). The engineering
units must match the units selected in the parameter XD_SCALE of the Analog Input
block that reads the channel with this value.
TERTIARY_VALUE is the value and status of the static pressure.
TERTIARY_VALUE_RANGE is the limits of the TERTIARY_VALUE, and it is a read
only parameter, while the units of the TERTIARY_VALUE can be changed as desired
(changing the units of the value automatically changes the limits). The engineering units
must match the units selected in the parameter XD_SCALE of the Analog Input Block that
reads the channel with this value.
Electronics housing temperature
Electronics housing temperature is the value and status of the temperature of the electronic
housing. The units can be changed as desired. The engineering units must match the units
selected in the parameter XD_SCALE of the Analog Input block that reads the channel
with this value.
