Configuration
Primary Variable (PV)
Selections for this Variable are Mass Flow, Volumetric Flow, Velocity Flow, and Process
Temperature. The Primary Variable is the variable mapped to the analog output.
Secondary Variable (SV)
Selections for this Variable include all Variables that can be mapped to PV, and also Vortex
Frequency, Pulse Output Frequency, Totalizer Value, Calculated Process Density, Electronics
Temperature, and Cold Junction (CJ) Temperature.
Tertiary Variable (TV)
Selections for this Variable are identical to those of the Secondary Variable.
Quaternary Variable (4V)
Selections for this Variable are identical to those of the Secondary Variable.
3.2.12 PV units
Selections for this include all units available for the selection of PV. This will set the units for the
flow rate or process temperature.
3.2.13 Range values
Range Values enables you to maximize resolution of analog output. The meter is most accurate
when operated within the expected flow ranges for your application. Setting the range to the
limits of expected readings will maximize flowmeter performance.
The range of expected readings is defined by the Lower Range Value (LRV) and Upper Range
Value (URV). Set the LRV and URV within the limits of flowmeter operation as defined by the line
size and process material for your application. Values set outside that range will not be
accepted.
Primary Variable Upper Range Value (PV URV)
This is the 20 mA set point for the meter.
