1.3System description
The Rosemount 8800D Vortex Flowmeter consists of a meter body and transmitter, and
measures volumetric flow rate by detecting the vortices created by a fluid passing by the
shedder bar.
The meter body is installed in-line with process piping. A sensor is located at the end of the
shedder bar which creates a sine wave signal due to the passing vortices. The transmitter
measures the frequency of the sine wave and converts it into a flowrate.
Process Variables for the Rosemount™ 8800D provides the flowmeter output. When
commissioning a flowmeter, review each process variable, its function and output, and take
corrective action if necessary before using the flowmeter in a process application.

2.1.1Primary Variable (PV)
FastKeys
The measured value of the variable mapped to the primary variable. This can be either
Process Temperature (MTA option only) or Flow. Flow variables are available as mass,
volume, corrected volume, or velocity. When bench commissioning, the flow values for
each variable should be zero and the temperature value should be the ambient
temperature.
If the units for the flow or temperature variables are not correct, refer to “Process Variable
Units” on page 4. Use the Process Variable Units function to select the units for your
application.

2.1.2Percent of Range
FastKeys
3, 4, 3, 2
The primary variable as a percentage of range provides a gauge as to where the measured
flow rate of the meter is within the configured range of the meter. For example, the range
may be defined as 0 gal/min to 20 gal/min. If the measured flow rate is 10 gal/min, the
percent of range is 50 percent.
2.1.3Analog Output
FastKeys
The analog output variable provides the analog value for the primary variable. The analog
output refers to the industry standard output in the 4–20 mA range. Check the analog
output value against the actual loop reading given by a multi-meter. If it does not match, a
4–20 mA trim is required. See “Analog Trim” on page 51.

FastKeys
The unit from which the conversion is made. Select one of the Field Communicator defined
unit options:
Provides the time unit from which to calculate the special units. For example, if the special
unit is a volume per minute, select minutes. Choose from the following units:
A user created custom flow unit. The special unit is limited to four characters. The Field
Communicator indicates the special unit with SPCL. The LCD display will display the actual
four character user defined special unit.
Used to relate base units to special units. For a straight conversion of volume units from one
to another, the conversion number is the number of base units in the new unit.
For example, if it is desired to convert from gallons to beer barrels there are 31 gallons in a
beer barrel. The conversion equation is as follows (where beer barrels is the new volume
unit):
Provides the output reading of the totalizer. Its value is the amount of liquid or gas that has
passed through the flowmeter since the totalizer was last reset.
Totalizer Control
FastKeys
Allows the totalizer to be started, stopped, or reset.
Start—Starts the totalizer counting from its current value.
Stop—Interrupts the totalizer count until it is restarted again. This feature is often used
during pipe cleaning or other maintenance operations.
Reset—Returns the totalizer value to zero. If the totalizer was running, it will continue to run
starting at zero.

FastKeys
Used to configure the flow parameter (volume, mass, velocity, or corrected volume flow)
that will be totaled.
Note
The totalizer value is saved in the non-volatile memory of the electronics every three
seconds. Should power to the transmitter be interrupted, the totalizer value will start at the
last saved value when the power is re-applied.
Note
Changes that affect the density, density ratio, or compensated K-Factor will affect the
totalizer value being calculated. These changes will not cause the existing totalizer value to
be recalculated.
Note
In order to totalize in compensated mass flow or compensated corrected volume flow, for
units with the MTA option only, set pulse output to match the totalizer configuration even if
the pulse output was not ordered.

2.2Basic setup
Configuration
May 2016
FastKeys
The Rosemount 8800D must be configured for certain basic variables in order to be
operational. In most cases, all of these variables are pre-configured at the factory.
Configuration may be required if your Rosemount 8800D is not configured or if the
configuration variables need revision. The basic setup wizard will take you through all the
steps required to set up the Rosemount Vortex meter for basic operation.
The remainder of this section contains details about how to enter basic configuration
parameters in order to manually configure the Rosemount 8800D.

2.2.3Process configuration
The flowmeter can be used for liquid or gas/steam applications, but it must be configured
specifically for the application. If the flowmeter is not configured for the proper process,
readings will be inaccurate. Select the appropriate process configuration parameters for
your application:

Set Process Fluid
FastKeys
Select the fluid type—either Liquid, Gas/Steam, Tcomp Sat Steam, or Tcomp Liquids. Tcomp
Sat Steam and Tcomp Liquids require the MTA Option and provide dynamic density
compensation based on the process temperature reading.
Needed for the electronics to compensate for thermal expansion of the flowmeter as the
process temperature differs from the reference temperature. Process temperature is the
temperature of the liquid or gas in the line during flowmeter operation.
May also be used as a back-up temperature value in the event of a temperature sensor
failure if the MTA option is installed.
2, 2, 1, 1, 4
Fixed Process Density
FastKeys
A Fixed Process Density must be accurately configured if mass flow or corrected volume
flow measurements are used. In mass flow it is used to convert volume flow to mass flow. In
corrected volume flow it is used with the base process density to derive a density ratio
which in turn is used to convert volume flow to corrected volume flow. In temperature
compensated fluids the fixed process density is still required as it is used to convert volume
flow sensor limits to sensor limits for temperature compensated fluids.
Note
If mass or corrected volume units are chosen, you must enter the density of your process
fluid into the software. Be careful to enter the correct density. The mass flow rate and
density ratio are calculated using this user-entered density, and unless the transmitter is in
TComp Sat Steam or TComp Liquids mode where changes in density are automatically
being compensated for, any error in this number will cause error in the measurement.
2, 2, 3, 1
Base Process Density
FastKeys
The density of the fluid at base conditions. This density is used in corrected volume flow
measurement. It is not required for volume flow, mass flow, or velocity flow. The Base
Process Density is used with the Process Density to calculate the Density Ratio. In
temperature compensated fluids, the Process Density is calculated by the transmitter. In
non-temperature compensated fluids the Fixed Process Density is used to calculate a fixed
Density Ratio. Density Ratio is used to convert actual volumetric flow to standard
volumetric flow rates based on the following equation:
2, 2, 3, 2, 1
2.2.4Reference K-factor
FastKeys
A factory calibration number relating the flow through the meter to the shedding frequency
measured by the electronics. Every 8800 meter manufactured by Emerson is run through a
water calibration to determine this value.

May 2016
FastKeys
2, 2, 1, 4, 2
Enables the user to specify the type of flange on the flowmeter for later reference. This
variable is preset at the factory but can be changed if necessary.
The pipe ID (inside diameter) of the pipe adjacent to the flowmeter can cause entrance
effects that may alter flowmeter readings. Configuring the actual mating pipe inside
diameter will correct for theses effects. Enter the appropriate value for this variable.
Pipe ID values for schedule 10, 40, and 80 piping are given in Ta bl e 2 - 1 . If the mating pipe ID
is not listed in the table, confirm pipe ID with manufacturer or measure the pipe ID.

FastKeys
Enables you to set the upper and lower range values in order to maximize the resolution of
the 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.

2.2.10Damping
Reference Manual
00809-0100-4004, Rev DC
FastKeys
Damping changes the response time of the flowmeter to smooth variations in output
readings caused by rapid changes in input. Damping is applied to the Analog Output, Primary Varia ble, Percent of Range, and Vortex Frequency.
The default damping value is 2.0 seconds. This can be configured to any value between 0.2
to 255 seconds when PV is a flow variable or 0.4 to 32 seconds when PV is Process
Temperature. Determine the appropriate damping setting based on the necessary response
time, signal stability, and other requirements of the loop dynamics in your system.
Note
If the vortex shedding frequency is slower than the damping value selected, no damping is
applied. Process Temperature damping can be modified when PV is set to Process
Tem p er at ur e.

2.2.11Optimize DSP (Digital Signal Processing)
FastKeys
A function that can be used to optimize the range of the flowmeter based on the density of
the fluid. The electronics uses process density to calculate the minimum measurable flow
rate, while retaining at least a 4:1 signal to the trigger level ratio. This function will also reset
all of the filters to optimize the flowmeter performance over the new range. If the
configuration of the device has changed, this method should be executed to ensure the
signal processing parameters are set to their optimum settings. For dynamic process
densities, select a density value that is lower than the lowest expected flowing density.
