4Pre-installation
4.1Planning
For a successful installation, consider each aspect of your application and the
meter you are installing.
4.1.1Sizing
To determine the correct meter size for optimal flow meter performance:
• Determine the limits of measuring flow.
• Determine the process conditions so that they are within the stated
requirements for Reynolds number and velocity.
For sizing details, refer to the product reference manual.
Sizing calculations are required to select the proper flow meter size. These
calculations provide pressure loss, accuracy, and minimum and maximum
flow rate data to guide in proper selection. Vortex sizing software can be
found using the Selection and Sizing tool. The Selection and Sizing tool can
be accessed online or downloaded for offline use using this link:
www.Emerson.com/FlowSizing.
4.1.2Wetted material selection
Ensure that the process fluid is compatible with the meter body wetted
materials when specifying the Rosemount 8800D. Corrosion will shorten the
life of the meter body. Consult recognized sources of corrosion data or
contact Emerson Flow Sales Representative for more information.
Note
If Positive Material Identification (PMI) is required, perform test on a
machined surface.
4.1.3Orientation
The best orientation for the meter depends on the process fluid,
environmental factors, and any other nearby equipment.
Vertical installation
Vertical, upward, installation allows upward process liquid flow and is
generally preferred. Upward flow ensures that the meter body always
remains full and that any solids in the fluid are evenly distributed.
The meter can be mounted in the vertical down position when measuring
gas or steam flows. This type of application is strongly discouraged for liquid
flows, although it can be done with proper piping design.

August 2020Quick Start Guide
Figure 4-1: Vertical installation
AB
A. Liquid or gas flow
B. Gas flow
Note
To ensure the meter body remains full, avoid downward vertical liquid flows
where back pressure is inadequate.
Horizontal installation
For horizontal installation, the preferred orientation is to have the
electronics installed to the side of the pipe. In liquid applications, this helps
prevent any entrained air or solids from striking the shedder bar and
disrupting the shedding frequency. In gas or steam applications, this helps
prevent any entrained liquid (such as condensate) or solids do not strike the
shedder bar and disrupt the shedding frequency.

Quick Start Guide 9
Quick Start Guide August 2020
High-temperature installations
The maximum process temperature for integral electronics is dependent on
the ambient temperature where the meter is installed. The electronics must
not exceed 185 °F (85 °C).
Figure 4-3 shows combinations of ambient and process temperatures
needed to maintain a housing temperature of less than 185 °F (85 °C).

4.1.4Location
Hazardous area
The transmitter has an explosion-proof housing and circuitry suitable for
intrinsically safe and non-incendive operation. Individual transmitters are
clearly marked with a tag indicating the certifications they carry. See Product
certifications.
Environmental considerations
Avoid excessive heat and vibration to ensure maximum flow meter life.
Typical problem areas include high-vibration lines with integrally mounted
electronics, warm-climate installations in direct sunlight, and outdoor
installations in cold climates.
Although the signal conditioning functions reduce susceptibility to
extraneous noise, some environments are more suitable than others. Avoid
placing the flow meter or its wiring close to devices that produce high
intensity electromagnetic and electrostatic fields. Such devices include
electric welding equipment, large electric motors and transformers, and
communication transmitters.
Upstream and downstream piping
The meter may be installed with a minimum of ten diameters (D) of straight
pipe length upstream and five diameters (D) of straight pipe length
downstream.
To achieve reference accuracy, straight pipe lengths of 35D upstream and
5D downstream are required. The value of the K-factor may shift up to 0.5%
when the upstream straight pipe length is between 10D and 35D. For
Quick Start Guide 11
Quick Start Guide August 2020
optional K-factor corrections, see Rosemount™ 8800 Vortex Installation Effects
Technical Data Sheet.
Steam piping
For steam applications, avoid installations such as the one shown in the
following figure. Such installations may cause a water-hammer condition at
start-up due to trapped condensation. The high force from the water
hammer can stress the sensing mechanism and cause permanent damage to
the sensor.
Figure 4-5: Wrong steam pipe installation
Pressure and temperature transmitter location
When using pressure and temperature transmitters in conjunction with the
vortex flow meter for compensated mass flows, install the transmitter(s)
downstream of the vortex flow meter.

Minimum power supply voltage required
R(Ω)max = 41.7 (Vps – 10.8 V).
Additional wiring information
• The DC power supply should provide power with less than two percent
ripple. The total resistance load is the sum of the resistance of the signal
wiring and the load resistance of the controller, indicator, and related
pieces. Note that the resistance of intrinsic safety barriers, if used, must
be included.
• If a Smart Wireless THUM™ Adapter is being used with the flow meter to
exchange information via IEC 62591 (WirelessHART® Protocol)
technology, a minimum loop resistance of 250 ohms is required. In
addition, a minimum power supply voltage (Vps) of 19.3 volts will be
required to output 24 mA.
• If a single power supply is used to power more than one transmitter, the
power supply used and circuitry common to the transmitters should not
have more than 20 ohms of impedance at 1200 Hz. See Table 4-1.

4.1.6Power supply (FOUNDATION fieldbus)
The flowmeter requires 9-32 Vdc at the power terminals. Each fieldbus
power supply requires a power conditioner to decouple the power supply
output from the fieldbus wiring segment.
4.2Commissioning
For proper configuration and operation, commission the meter before
putting it into operation. Bench commissioning also enables you to check
hardware settings, test the flowmeter electronics, verify flowmeter
configuration data, and check output variables. Any problems can be
corrected—or configuration settings changed—before going out into the
installation environment. To commission on the bench, connect a
configuration device to the signal loop in accordance the device
instructions.
(20 °C) equivalent
4.2.1HART jumper configuration
Two jumpers on the transmitter specify the alarm and security modes. Set
these jumpers during the commissioning stage to avoid exposing the
electronics to the plant environment. The two jumpers can be found on the
electronics board stack or on the LCD meter.
Alarm
Security
Quick Start Guide 15
As part of normal operations, the transmitter continuously runs
a self-diagnostic routine. If the routine detects an internal failure
in the electronics, flow meter output is driven to a low or high
alarm level, depending on the position of the failure mode
jumper. The factory sets the jumper according to the
Configuration Data Sheet, if applicable, or HI by default.
You can protect the configuration data with the security lockout
jumper. With the security lockout jumper ON, any configuration
changes attempted on the electronics are disallowed. You can
still access and review any of the operating parameters and scroll
Quick Start Guide August 2020
through the available parameters, but no changes can be made.
The factory sets the jumper according to the Configuration Data
Sheet, if applicable, or OFF by default.
Note
If you will be changing configuration variables frequently, it may
be useful to leave the security lockout jumper in the OFF position
to avoid exposing the flow meter electronics to the plant
environment.
To access the jumpers, remove the transmitter electronics housing or the
LCD cover (if equipped) opposite of the terminal blocks, See Figure 4-8 and
Figure 4-9.
Figure 4-8: Alarm and security jumpers (no LCD option)
The failure mode alarm output levels differ from the output values that
occur when the operating flow is outside the range points. When the
operating flow is outside the range points, the analog output continues to
track the operating flow until reaching the saturation value listed below; the
output does not exceed the listed saturation value regardless of the
operating flow. For example, with standard alarm and saturation levels and
flows outside the 4–20 mA range points, the output saturates at 3.9 mA or
20.8 mA. When the transmitter diagnostics detect a failure, the analog
output is set to a specific alarm value that differs from the saturation value
to allow for proper troubleshooting. The saturation and alarm levels are
software selectable between Rosemount Standard and NAMUR levels.
Table 4-2: Analog output: standard alarm values vs. saturation values
Level4–20 mA saturation value4–20 mA alarm value

Quick Start Guide 17
Quick Start Guide August 2020
4.2.2FOUNDATION fieldbus jumper configuration
Two jumpers on the transmitter specify the simulation and security modes.
Set these jumpers during the commissioning stage to avoid exposing the
electronics to the plant environment. The two jumpers can be found on the
electronics board stack or on the LCD meter.
Simulate
The simulate enable jumper is used in conjunction with the
Analog Input (AI) function block simulation. The jumper is also
used as a lock-out feature for the AI function block. To enable
the simulate enable feature, the jumper must transition from
OFF to ON after power is applied to the transmitter, preventing
the transmitter from being accidentally left in simulator mode.
The factory sets the jumper to OFF by default.
Security
You can protect the configuration data with the security lockout
jumper. With the security lockout jumper ON, any configuration
changes attempted on the electronics are disallowed. You can
still access and review any of the operating parameters and
scroll through the available parameters, but no changes can be
made. The factory sets the jumper to OFF by default.
To access the jumpers, remove the transmitter LCD cover (if equipped) or
the electronics housing cover opposite of the terminal blocks, See Figure
The flow meter is wet-calibrated at the factory and needs no further
calibration during installation. The calibration factor (K-factor) is indicated
on each meter body and is entered into the electronics. Verification can be
accomplished with a configuration device.

the meter body, points in the direction of the flow in the pipe.
5.3
Quick Start Guide 21
Gaskets
The flow meter requires gaskets supplied by the user. Be sure to select
gasket material that is compatible with the process fluid and pressure
ratings of the specific installation.
Note
Ensure the inside diameter of the gasket is larger than the inside diameter of
the flow meter and adjacent piping. If gasket material extends into the flow
stream, it will disturb the flow and cause inaccurate measurements.
Quick Start Guide August 2020
5.4Insulation
Insulation should extend to the end of the bolt on the bottom of the meter
body and should leave at least 1-in. (25 mm) of clearance around the
electronics bracket. The electronics bracket and electronics housing should
not be insulated. See #unique_12/unique_12_Connect_42_Insulation.
Figure 5-2: Insulation best practice to prevent electronics overheating
CAUTION
To avoid damage to electronics in high temperature installations, and for
both integral and remote electronics, only insulate the meter body as
shown, do not insulate the area around the electronics.

22Rosemount™ 8800D Series Vortex Flow Meter
Flanged-style flow meter mounting
Most vortex flow meters use a flanged-style process connection. Physical
mounting of a flanged-style flow meter is similar to installing a typical
section of pipe. Conventional tools, equipment, and accessories (such as
bolts and gaskets) are required. Tighten the nuts following the sequence
shown in Figure 5-4.
Note
The required bolt load for sealing the gasket joint is affected by several
factors, including operating pressure and gasket material, width, and
condition. A number of factors also affect the actual bolt load resulting from
a measured torque, including condition of bolt threads, friction between the
nut head and the flange, and parallelism of the flanges. Due to these
August 2020Quick Start Guide
application-dependent factors, the required torque for each application may
be different. Follow the guidelines outlined in ASME PCC-1 for proper bolt
tightening. Make sure the flow meter is centered between flanges of the
same nominal size as the flow meter.

5.7Cable glands
If you are using cable glands instead of conduit, follow the cable gland
manufacturer’s instructions for preparation and make the connections in a
conventional manner in accordance with local or plant electrical codes. Be
sure to properly seal unused ports to prevent moisture or other
contamination from entering the terminal block compartment of the
electronics housing.
5.8Flow meter grounding
Grounding is not required in typical vortex applications; however, a proper
ground will eliminate possible noise pickup by the electronics. Grounding
straps may be used to ensure that the meter is grounded to the process
piping. If you are using the transient protection option (T1), grounding
straps are required to provide a proper low impedance ground.
Note
Properly ground flow meter body and transmitter per the local code.
To use grounding straps, secure one end of the grounding strap to the bolt
extending from the side of the meter body and attach the other end of each
grounding strap to a suitable ground. See Figure 5-6.

The Internal Ground Connection screw is inside the FIELD
TERMINALS side of the electronics housing. This screw is
identified by a ground symbol ( ), and is standard on all
Rosemount 8800D transmitters.
This assembly is located on the outside of the electronics
housing and is included with the optional transient
protection terminal block (Option Code T1). The External
Ground Assembly can also be ordered with the
transmitter (Option Code V5) and is automatically
included with certain hazardous area approvals. See
Figure 5-6 for the location of the external ground
assembly.
August 2020Quick Start Guide
transmitter case is properly grounded. For transient terminal block
grounding, see the Reference Manual. Use the above guidelines to ground
the transmitter case. Do not run the transient protection ground wire with
signal wiring as the ground wire may carry excessive electric current if a
lightning strike occurs.
5.10Conduit installation
Prevent condensation in any conduit from flowing into the housing by
mounting the flowmeter at a high point in the conduit run. If the flowmeter
is mounted at a low point in the conduit run, the terminal compartment
could fill with fluid.
If the conduit originates above the flowmeter, route conduit below the
flowmeter before entry. In some cases a drain seal may need to be installed.

Wiring
The signal terminals are located in a compartment of the electronics housing
separate from the flow meter electronics. Connections for a configuration
tool and an electric current test connection are above the signal terminals.
Note
A power disconnect is required to remove power from the transmitter for
maintenance, removal, and replacement.
Common wiring practices
Twisted pairs are required to minimize noise pickup in the 4–20 mA signal
and digital communication signal. For high EMI/RFI environments, shielded
signal wire is required and recommended in all other installations. To ensure
A
Quick Start Guide August 2020
communication, wiring should be 24 AWG (0.205 mm²) or larger, and not
exceed 5,000 ft (1500 m).
5.11.1 Analog output
The flow meter provides a 4–20 mA dc isolated electric current output,
linear with the flow rate. To make connections, remove the FIELD
TERMINALS side cover of the electronics housing. All power to the
electronics is supplied over the 4–20 mA signal wiring. Connect the wires as
shown.
Note
Twisted pairs are required to minimize noise pickup in the 4–20 mA signal
and digital communication signal. For high EMI/RFI environments, shielded
signal wire is required and recommended in all other installations. To ensure
communication, wiring should be 24 AWG or larger, and not exceed 5,000 ft
(1500 m).

5.11.2 FOUNDATION fieldbus wiring
Each fieldbus power supply requires a power conditioner to decouple the
power supply output from the fieldbus wiring segment.
All power to the transmitter is supplied over the segment wiring. Use
shielded, twisted pair for best results. For new installations or to get
maximum performance, twisted pair cable designed especially for fieldbus
should be used. Table 5-3 lists the cable characteristics and ideal
specifications.

Note
The number of devices on a fieldbus segment is limited by the power supply
voltage, the resistance of the cable, and the amount of current drawn by
each device.
Transmitter wiring connection
To make the transmitter wiring connection, remove the FIELD TERMINALS
end cover on the electronics housing. Connect the power leads to the
positive (+) and negative (–) terminals. The power terminals are polarity
insensitive: the polarity of the DC power leads does not matter when
connecting to the power terminals. When wiring to screw terminals,
crimped lugs are recommended. Tighten the terminals to ensure adequate
contact. No additional power wiring is required.

CAUTION
To prevent moisture from entering the coaxial cable connections, install the
interconnecting coaxial cable in a single dedicated conduit run or use sealed
cable glands at both ends of the cable.
In remote mount configurations when ordered with a hazardous area option
code, the remote sensor cable and the interconnecting thermocouple cable
(MTA or MCA option) are protected by separate intrinsic safety circuits, and
must be segregated from each other, other intrinsically safe circuits, and
non-intrinsically safe circuits per local and national wiring code.
CAUTION
The coaxial remote cable cannot be field terminated or cut to length. Coil
any extra coaxial cable with no less than a 2-in. (51 mm) radius.
1. If you plan to run the coaxial cable in conduit, carefully cut the
conduit to the desired length to provide for proper assembly at the
housing. A junction box may be placed in the conduit run to provide a
space for extra coaxial cable length.
2. Slide the conduit adapter or cable gland over the loose end of the
coaxial cable and fasten it to the adapter on the meter body support
tube.
3. If using conduit, route the coaxial cable through the conduit.
4. Place a conduit adapter or cable gland over the end of the coaxial
cable.

2. Slowly pull the electronics housing out of the support tube.
CAUTION
Do not pull the housing more than 1.5 in. (40 mm) from the top of
the support tube until the sensor cable is disconnected. Damage to
the sensor may occur if this sensor cable is stressed.
3. Unscrew the sensor cable from the housing with a 5/16” open end
wrench.
4. Rotate the housing to the desired orientation.
5. Hold it in this orientation while you screw the sensor cable onto the
base of the housing.

6Basic configuration
The transmitter 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 transmitter is not configured
or if the configuration variables need revision. The basic setup section
includes parameters typically required for basic operation.
Note
ProLink III paths are only applicable to HART devices. For more information
on Fieldbus devices, refer to the 8800D product manual for Fieldbus
protocol (00809-0100-4772).
6.1Process variables
Process variables define the flow meter output. When commissioning a flow
meter, review each process variable, its function and output, and take
corrective action if necessary before using the flow meter in a process
application.
6.1.1Primary variable mapping
Allows the user to select which variables the transmitter will output.
The Primary Variable is also the Analog Output variable.
This can be either Process Temperature (MTA or MCA option only) or Flow.
Flow variables are available as Corrected Volume Flow, Mass Flow, Velocity
Flow, or Volume Flow. 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. Use the Process Variable Units function to select the
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.

The quickest way to identify and distinguish between flow meters. Flow
meters can be tagged according to the requirements of your application.
The tag may be up to eight characters long.
The flow meter can be used for liquid, gas, or steam applications, but it must
be configured specifically for the application. If the flow meter is not
configured for the proper process, readings will be inaccurate. Select the
appropriate process configuration parameters for your application:
Quick Start Guide August 2020
Set process fluid
NonMultiVariable
and MTA meters
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. For more information on
temperature compensation configuration, please
consult the advance functionality of the Operation
section of the 00809-0100-4004 Manual.
MPA and MCA
meters
Select the fluid type - either Liquid, Gas, or Steam. For
more information on pressure and temperature
compensation configuration, please consult the
advanced installation and advanced configuration
sections of the 00809-1100-4004 Manual.
Fixed process temperature
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 or MCA option is installed.
Fixed process density
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:
Meters with
MTA option
The transmitter is in TComp Sat Steam or TComp Liquids for
MTA meters. When the process fluid is set to Tcomp Sat
Steam or TComp Liquids, the changes in density are
automatically being compensated for and any error in the
user-entered density will cause error in the measurement.

Meters with
MPA or
MCA option
Base process density
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:
Density ratio = density at actual (flowing) conditions/density at standard
(base) conditions
Actual Compensation reads Temperature, Pressure or
Pressure and Temperature Compensation. If Actual
Compensation reads Temperature, Pressure or Pressure and
Temperature Compensation, density is automatically
compensated, any error in the user-entered density will
result in error in the measurement.
A factory calibration number relating the flow through the meter to the
shedding frequency measured by the electronics. Every vortex meter
manufactured by Emerson is run through a water calibration to determine
this value.
Enables the user to specify the type of flange on the flow meter for later
reference. This variable is preset at the factory but can be changed if
necessary.
The pipe I.D. (inside diameter) of the pipe adjacent to the flow meter can
cause entrance effects that may alter flow meter readings. Configuring the
actual mating pipe inside diameter will correct for theses effects. Enter the
appropriate value for this variable.
Pipe I.D. values for schedule 10, 40, and 80 piping are given in the following
table. If the mating pipe I.D. is not listed in the table, confirm it with the
manufacturer or measure it yourself.
Table 6-5: Pipe IDs for Schedule 10, 40, and 80 piping
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 flow meter
performance.
The range of expected readings is defined by the Lower Range Value and
Upper Range Value. Set the values within the limits of flow meter operation
as defined by the line size and process material for your application. Values
set outside that range will not be accepted.
Damping changes the response time of the flow meter to smooth variations
in output readings caused by rapid changes in input. Damping is applied to
the Analog Output, Primary Variable, 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.
Output
This is the 20 mA set point for the meter.
This is the 4 mA set point for the meter, and is typically
set to 0 when the primary variable is a flow variable.
Output
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 Temperature.

A function that can be used to optimize the range of the flow meter 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 flow meter 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
