Procedures and instructions in this manual may require special precautions to ensure the safety
of the personnel performing the operations. Refer to the safety messages, listed at the
beginning of each section, before performing any operations.
1.3 System description
The Rosemount 8600D 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 and creates an alternating sine wave due to the passing vortices. The transmitter
measures the frequency of the sine waves and converts it into a flowrate.
This manual is designed to assist in the installation and operation of the Rosemount 8600D
Vor tex Flowmeter.

2.2 Commissioning
Commission the Rosemount 8600D before putting it into operation. This ensures proper
configuration and operation of the meter. It 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 the Field Communicator or
Asset Management Solutions
loop in accordance with the specifications for your communicator.
2.2.1 General considerations
Before you install a flowmeter in any application, you must consider flowmeter sizing (the line
size) and location. Choose the correct flowmeter size for an application to increase rangeability
and minimize pressure drop and cavitation. Proper location of the flowmeter can ensure a clean
and accurate signal. Follow the installation instructions carefully to reduce start-up delays, ease
maintenance, and ensure optimum performance.
2.2.2 Flowmeter sizing
™
(AMS) software (or other communications device) to the signal
Section 2: Installation
January 2013
Correct meter sizing is important for flowmeter performance. The Rosemount 8600D is capable
of processing signals from flow applications within the limitations described in Appendix A:
Reference data. Full scale is continuously adjustable within these ranges.
To determine the correct flowmeter size for an application, process conditions must be within
the stated requirements for Reynolds number and velocity. See Appendix A: Reference data for
sizing data.
Contact your local Rosemount Inc. sales representative to obtain a copy of Instrument Toolkit
which contains a sizing module for the Rosemount 8600D Vortex flowmeter. The vortex sizing
module will calculate valid flowmeter sizes based on user-supplied application information.
2.2.3 Flowmeter orientation
Design process piping so the meter body will remain full, with no entrapped air. Allow enough
straight pipe both upstream and downstream of the meter body to ensure a nonskewed,
symmetrical profile. Install valves downstream of the meter when possible.
Vertical installation
Vertical 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.
®
Installation
The vortex meter can be mounted in the vertical down position when measuring gas or steam
flows. This type of application should be strongly discouraged for liquid flows, although it can
be done with proper piping design.
Note
To ensure that the meter body remains full, avoid downward vertical
liquid flows where back pressure is inadequate.

electronics to the side of the pipe.
(PREFERRED ORIENTATION)

electronics below the pipe.
(ACCEPTABLE ORIENTATION)
January 2013
Horizontal installation
For horizontal installation, the preferred orientation is to have the electronics installed to the
side of the pipe. In liquid applications, this ensures any entrapped air or solids do not strike the
shedding bar and disrupt the shedding frequency. In gas or steam applications, this ensures that
any entrained liquid (such as condensate) or solids do not strike the shedder bar and disrupt the
shedding frequency.
High-Temperature installations
Install the meter body so the electronics are positioned to the side of the pipe or below the pipe
as shown in Figure 2-2. Insulation may be required around the pipe to maintain an electronics
temperature below 185 °F (85 °C).
Figure 2-2. Examples of High-Temperature Installations
Reference Manual
00809-0100-4860, Rev BC
6
Steam installations
For steam applications, avoid installations such as the one shown in Figure 2-3. Such
installations may cause a water-hammer condition at start-up due to trapped condensate. The
high force from the water hammer can over stress the sensing mechanism and cause permanent
damage to the sensor.

00809-0100-4860, Rev BC
Section 2: Installation
January 2013
Upstream/Downstream piping
The vortex 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.
Rated accuracy is based on the number of pipe diameter from an upstream disturbance. No
K-factor correction is required if the meter is installed with 35 D upstream and 5 D downstream.
The value of the K-factor may shift up to 0.5% when the upstream straight pipe length is
between 10D and 35D. Please see Technical Data Sheet (00816-0100-3250) on Installation
Effects for optional K-factor corrections. This effect can be corrected for using the Installation
Effect Correction Factor (See page 52).
Pressure and temperature transmitter location
When using pressure and temperature transmitters in conjunction with the Rosemount 8600D
for compensated mass flows, install the transmitter(s) downstream of the Vortex Flowmeter.
See Figure 2-4.
Figure 2-4. Pressure and Temperature Transmitter Location
2.2.4 Wetted material selection
2.2.5 Environmental considerations
Installation
Ensure that the process fluid is compatible with the meter body wetted materials when
specifying the Rosemount 8600D. Corrosion will shorten the life of the meter body. Consult
recognized sources of corrosion data or contact your Rosemount Sales Representative for more
information.
Note
For accurate results perform a Positive Material Identification (PMI) test on a machined surface.
Avoid excessive heat and vibration to ensure maximum flowmeter life. Typical problem areas
include high-vibration lines with integrally mounted electronics, warm-climate installations in
direct sunlight, and outdoor installations in cold climates.
7
Section 2: Installation
January 2013
Although the signal conditioning functions reduce susceptibility to extraneous noise, some
environments are more suitable than others. Avoid placing the flowmeter 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.
2.3 Hazardous locations
The Rosemount 8600D 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.
2.4 Hardware configuration
The hardware jumpers on the Rosemount 8600D enable you to set the alarm and security. (See
Figure 2-5.) To access the jumpers, remove the electronics housing cover from the electronics
end of the Rosemount 8600D. If your Rosemount 8600D includes an LCD option, the alarm and
security jumpers are found on the face of the LCD indicator. (See Figure 2-6 on page 10.)
Reference Manual
00809-0100-4860, Rev BC
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 flowmeter electronics to the plant environment.
Set these jumpers during the commissioning stage to avoid exposing the electronics to the
plant environment.
Figure 2-5. Alarm and Security Jumpers

Installation
Reference Manual
00809-0100-4860, Rev BC
Alarm
As part of normal operations, the Rosemount 8600D continuously runs a self-diagnostic
routine. If the routine detects an internal failure in the electronics, flowmeter output is driven to
a low or high alarm level, depending on the position of the failure mode jumper.
The failure mode jumper is labeled ALARM and is set at the factory per the CDS (Configuration
Data Sheet); the default setting is HI.
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
changes, but no actual changes will be permitted. The security lockout jumper is labeled
SECURITY and is set at the factory per the CDS; the default setting is OFF.
2.4.1 Failure mode vs. saturation output values
Section 2: Installation
January 2013
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.
.
Table 2-1. Analog Output: Standard Alarm Values vs. Saturation Values
Level 4—20 mA Saturation Value 4—20 mA Alarm Value
Low 3.9 mA < 3.75 mA
High 20.8 mA 21.75 mA

2.5 Meter body installation tasks
The installation tasks include detailed mechanical and electrical
installation procedures.
2.5.1 Handling
Handle all parts carefully to prevent damage. Whenever possible, transport the system to the
installation site in the original shipping containers. Keep the shipping plugs in the conduit
connections until you are ready to connect and seal them.
Note
Do not lift the flowmeter by the transmitter. Lift the meter by the meter body. Lifting supports
can be tied around the meter body as illustrated below if necessary.
Section 2: Installation
January 2013
2.5.2 Flow direction
Mount the meter body so the FORWARD end of the flow arrow, shown on the meter body,
points in the direction of the flow in the pipe.
2.5.3 Gaskets
The Rosemount 8600D requires flange gaskets supplied by the user, and sensor gaskets
supplied with the meter. Be sure to select gasket material that is compatible with the process
fluid and pressure ratings of the specific installation.
Note
Ensure that the inside diameter of the flange gasket is larger than the inside
diameter of the flowmeter and adjacent piping. If gasket material extends into the flow stream,
it will disturb the flow and cause inaccurate measurements.

2.5.5 Flanged-style flowmeter mounting
Physical mounting of a flanged-style flowmeter 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 2-8.
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 application-dependent factors, the
required torque for each application may be different. Follow the guidelines outlined in the ASME
Pressure Vessel Code (Section VIII, Division 2) for proper bolt tightening. Make sure the flowmeter is
centered between flanges of the same nominal size as the flowmeter.
Figure 2-8. Flange Bolt Torquing Sequence
Section 2: Installation
January 2013
2.5.6 Flowmeter 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.
Installation
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.
13
Section 2: Installation
January 2013
2.6 Electronics considerations
Both integral and remote mounted electronics require input power at the electronics. For
remote mount installations, mount the electronics
against a flat surface or on a pipe that is up to two inches (50 mm) in diameter.
Remote mounting hardware includes an L bracket that is stainless steel and one stainless steel
u-bolt. See Appendix A: Reference data, “Dimensional drawings” on page 107 for dimensional
information.
2.6.1 High-Temperature installations
Install the meter body so the electronics are positioned to the side of or
below the pipe as shown in Figure 2-2 on page 6. Insulation may be required around the pipe to
maintain an ambient transmitter temperature below 185 °F (85 °C) or the more restrictive
temperature ratings marked on hazardous locations tags.
2.6.2 Conduit connections
Reference Manual
00809-0100-4860, Rev BC
The electronics housing has two ports for 1/2–14 NPT or M201.5 conduit connections. Unless
marked otherwise conduit entries in the housing are
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. Additional conduit entry types are available via
adapters.
Note
In some applications it may be necessary to install conduit seals and arrange for conduits to
drain to prevent moisture from entering the wiring compartment.
2.6.3 High-Point 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.

2.6.4 Cable gland
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.
2.6.5 Grounding the transmitter case
The transmitter case should always be grounded in accordance with national and local electrical
codes. The most effective transmitter case grounding method is direct connection to earth
ground with minimal impedance. Methods for grounding the transmitter case include:
Internal Ground Connection: 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 8600D transmitters.
External Ground Assembly: This assembly 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.
Note
Grounding the transmitter case using the threaded conduit connection may not provide a
sufficient ground. The transient protection terminal block (Option Code T1) does not provide
transient protection unless the transmitter case is properly grounded. See “Transient Terminal
Block” on page 27 for transient terminal block grounding. 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 current if a lightning strike occurs.

2.6.6 Wiring procedure
The signal terminals are located in a compartment of the electronics housing separate from the
flowmeter electronics. Connections for a HART-based communicator and a current test
connection are above the signal terminals. Figure 2-10 illustrates the power supply load
limitations for the flowmeter.
Note
A power disconnect is required to remove power from the transmitter for maintenance,
removal, and replacement.
Power supply
Power Supply Specifications:
Typical installations use a 22 Vdc – 28 Vdc power supply. The dc power supply should provide
clean power with less than 2% ripple. Refer to Figure 2-10 as a quick reference.
Loop resistance specification:
Reference Manual
00809-0100-4860, Rev BC
If HART communication is required, a minimum resistance of 250 dc is required between the
power supply and the transmitter. *Note: See the loop load calculation section to determine the
maximum allowable loop resistance as a function of power supply voltage.

in the equation above refers to the total loop load resistance. Technically, the total
loop load resistance is the sum of the loop load resistor, signal wiring resistance, and if
applicable, any intrinsic safety barriers. In a typical installation, the loop load resistor will largely
determine the total loop resistance. In some installations, depending on signal wire gauge and
signal wire length, and/or any IS barriers, the additional resistance may need to be accounted
for.
To minimize noise pickup on the 4-20 mA signal and any digital communications signal:
Twisted pair wiring is recommended.
Shielded signal wire is preferred.
For high EMI/RFI environments, shielded signal wire is required.
To ensure proper operation, wiring should be:
