Quick Start Guide
1.0 About this guide
This guide provides basic guidelines for the Rosemount™8600D Series Vortex
Flowmeter. It does not provide instructions for detailed configuration,
diagnostics, maintenance, service, troubleshooting, Explosion-proof,
Flameproof, or Intrinsically Safe (I.S.) installations. Refer to the Rosemount
8600D Reference Manual for more instruction. The manuals and this quick start
guide are also available electronically on EmersonProcess.com/Rosemount.
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the appropriate
local, national, and international standards, codes, and practices. Review the approvals section of the
Rosemount 8600D Reference Manual for any restrictions associated with a safe installation.
Before connecting a HART®-based communicator in an explosive atmosphere, make sure the instruments
in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.
Verify the operating atmosphere of the flowmeter is consistent with the appropriate product
certifications.
In an Explosion-proof/Flameproof installation, do not remove the flowmeter covers when power is applied
to the unit.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical
shock.

2.0 Mount the flowmeter
Design process piping so the meter body will remain full, with no entrapped air.
The vortex flowmeter can be installed in any orientation without affecting
accuracy. However, the following are guidelines for certain installations.
2.1 Vertical mounting
If the vortex flowmeter will be installed in a vertical orientation:
Install upward or downward flow for gas or steam.
Install upward flow for liquids.
Figure 1. Vertical Installation
A. Gas flow
B. Liquid or gas flow
2.2 Horizontal mounting
Figure 2. Horizontal Installation
A. Preferred installation—meter body installed with electronics to side of pipe
B. Acceptable installation—meter body installed with electronics above pipe
For steam and fluids with small solids content, it is recommended to have the
flowmeter installed with the electronics to the side of the pipe. This will minimize
potential measurement errors by allowing the condensate or solids to flow under
the shedder bar without interrupting the vortex shedding.

2.3 High temperature mounting
The maximum temperature for integral electronics is dependent on the ambient
temperature where the flowmeter is installed. The electronics must not exceed
185 °F (85 °C).
Figure 3 shows combinations of ambient and process temperatures needed to
maintain a housing temperature of less than 185 °F (85 °C).
Figure 3. Rosemount 8600D Ambient/Process Temperature Limits
The following orientations are recommended for applications with high process
temperatures.
Install with electronics head beside or below process pipe.
Insulation around pipe may be necessary to maintain ambient temperature
below 185 °F (85 °C).
Note
Insulate pipe and meter body only. Do not insulate support tube bracket or transmitter so heat
can be dissipated.
2.4 Steam installations
Avoid installation shown in Figure 4. Such conditions may cause a water-hammer
condition at start-up due to trapped condensation.

Figure 4. Improper Installation
2.5 Upstream/downstream requirements
The Rosemount 8600D Flowmeter may be installed with a minimum of ten
straight pipe diameters (D) upstream and five straight pipe diameters (D)
downstream by following the K-factor corrections as described in the 8800
Installation Effects Technical Data Sheet (00816-0100-3250). No K-factor
correction is required if 35 straight pipe diameters upstream (35D) and 10
straight pipe diameters downstream (10D) are present.
2.6 External pressure/temperature transmitters
When using pressure and temperature transmitters in conjunction with the
Rosemount 8600D for compensated mass flows, install the transmitters
downstream of the Rosemount 8600D flowmeter as shown in Figure 5.

2.7 Flanged-style installation
Figure 6. Flanged-Style Flowmeter Installation
A. Installation bolts and nuts (supplied by customer)
B. Gaskets (supplied by customer)
C. Flow
Note
The required bolt load for sealing the gasket joint is affected by several factors, including
operating pressure, 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
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 flowmeter is
centered between flanges of the same nominal size as the flowmeter.
2.8 Remote electronics
If you order one of the remote electronics options (options R10, R20, R30, or
RXX), the flowmeter assembly ships in two parts:
1. The meter body with an adapter installed in the support tube and an
interconnecting coaxial cable attached to it.
2. The electronics housing installed on a mounting bracket.
Mounting
Mount the meter body in the process flow line as described earlier in this section.
Mount the bracket and electronics housing in the desired location. The housing
can be repositioned on the bracket to facilitate field wiring and conduit routing.
Cable connections
Refer to Figure 7 and the instructions on page 7 to connect the loose end of the

3.0 Consider housing rotation
The entire electronics housing may be rotated in 90° increments for easy viewing.
Use the following steps to change the housing orientation:
1. Loosen the four housing rotation set screws at the base of the electronics
housing with a 5/32” hex wrench by turning the screws clockwise (inward) until
they clear the support tube.
2. Slowly pull the electronics housing out of the support tube.
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.
6. Place the electronics housing into the top of the support tube.
7. Use a hex wrench to turn the three housing rotation screws counter-clockwise
(outward) to engage the support tube.
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.
Do not rotate the housing while the sensor cable is attached to the base of the housing. This will stress the
cable and may damage the sensor.

4.0 Set jumpers and switches
Adjust jumpers to desired settings.
4.1 HART
If alarm and security jumpers are not installed, the flowmeter will operate
normally with the default alarm condition alarm high and the security off.
Figure 8. HART Jumpers and LCD Display
4.2 Power supply
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 leads and the load
resistance of the controller, indicator, and related pieces. Note that the resistance
of intrinsic safety barriers, if used, must be included.

5.0 Connect wiring and power up
5.1 Conduit 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.
Figure 10. Proper Conduit Installation with Rosemount 8600D
A. Conduit line
Use the following steps to wire the flowmeter:
1. Remove the housing cover on the side marked FIELD TERMINALS.
2. Connect the positive lead to the “+” terminal and the negative lead to the “-”
terminal as shown in Figure 11 for HART installations.
3. For HART installations utilizing the pulse output, connect the positive lead to
the “+” terminal of the pulse output and the negative lead to the “-” terminal
of the pulse output as shown in Figure 11. A separate 5 to 30 Vdc power
supply is required for the pulse output. Maximum switching current for the
pulse output is 120 mA.
Figure 11 shows wiring connections necessary to power a Rosemount 8600D and
enable communications with a hand-held Field Communicator.
4. Plug and seal unused conduit connections. Use pipe sealing tape or paste on
threads to ensure a moisture-tight seal. Housing conduit entries marked with
M20 will require M-20 x 1.5 blanking plug thread. Unmarked conduit entries
will require a 1/2 - 14 NPT blanking plug thread.
Do not connect the powered signal wiring to the test terminals. Power could damage the test diode in the
test connection. Twisted pairs are required to minimize noise pick up in the 4 - 20 mA signal and digital
communication signal. For high EMI/RFI environments, shielded signal wire is required and preferred in all
other installations. Use 24 AWG or larger wire and do not exceed 5,000 feet (1,500 meters). For ambient
temperatures above 140 °F (60 °C) use wire rated to 176 °F (80 °C).

Quick Start Guide
Note
Straight threads require a minimum of three wraps of tape to obtain a tight seal.
5. If applicable, install wiring with a drip loop. Arrange the drip loop so the
bottom is lower than the conduit connections and the flowmeter housing.

Note
Installation of the transient protection terminal block does not provide transient protection unless
the Rosemount 8600D case is properly grounded.
5.2 Cover jam screw
For transmitter housings shipped with a cover jam screw, the screw should be
properly installed once the transmitter has been wired and powered up. The
cover jam screw is intended to disallow the removal of the transmitter cover in
flameproof environments without the use of tooling. Follow these steps to install
the cover jam screw:

1. Verify the cover jam screw is completely threaded into the housing.
2. Install the transmitter housing cover and verify that the cover is tight against
the housing.
3. Using an M4 hex wrench, loosen the jam screw until it contacts the
transmitter cover.
4. Turn the jam screw an additional 1/2turn counterclockwise to secure the
cover.
Note
Application of excessive torque may strip the threads.
5. Verify that the cover cannot be removed.
6.0 Verify configuration
Before operating the Rosemount 8600D in an installation, you should review the
configuration data to ensure that it reflects the current application. In most cases,
all of these variables are pre-configured at the factory. Configuration may be
required if your flowmeter is not configured or if the configuration variables need
revision.
Rosemount recommends the following variables are reviewed before startup for
a HART configuration:
Tag
Transmitter Mode
Process Fluid
Reference K-Factor
Flange Type
Mating Pipe ID
PV Units
PV Damping
Process Temperature Damping
Fixed Process Temperature
Auto Adjust Filter
LCD Display Configuration (For units with a display only)
Density Ratio (For Standard or Normal flow units only)
Process Density and Density Units (For mass flow units only)
Variable Mapping
Range Values
Pulse Output Configuration (For units with a pulse output only)
