Rosemount 8800D
Mating Pipe ID
(Inside Diameter)
The Pipe ID (Inside Diameter) of the pipe adjacent to the flowmeter can
cause entrance effects that may alter flowmeter readings. You must specify
the exact inside diameter of the pipe to correct for these effects. Enter the
appropriate value for this variable.
Pipe ID values for schedule 10, 40, and 80 piping are given in Table 3 -1. If the
piping in your application is not one of these, you may need to contact the
manufacturer for exact Pipe ID.
f
Variable Mapping Allows the user to select which Variables the 8800D will output.
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.
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.
