1.2 Safety messages

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)

The meter body installed with the

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 M201.5 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:

 24 AWG or larger.

3.1 Review

Field Comm. 1, 5

Review the flowmeter configuration parameters set at the factory to ensure accuracy and
compatibility with your particular application of the flowmeter. Once you have activated the
Review function, scroll through the data list to check each variable in the configuration data list.

The last step of start-up and commissioning is to check the flowmeter output to ensure that the
flowmeter is operating properly. Rosemount 8600D digital process variables include: primary
variable, primary variable as a percent of range, analog output, vortex shedding rate, pulse
frequency, mass flow, volumetric flow, velocity flow, totalizer, electronics temperature,
calculated process density, cold junction temperature, and process temperature.

3.2 Process variables

Field Comm. 1, 1

The process variables for the Rosemount 8600D provide 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.

3.2.1 Primary Variable (PV)

Field Comm. 1, 1, 1

PV – 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, 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 “View other variables”

on page 30. Use the Process Variable Units function to select the units for your application.

3.2.2 PV% of range

Field Comm. 1, 1, 2

Percent of Range — The primary variable as a percentage of range provides a gauge as to where
the current measurement 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 current flow is 10 gal/min, the
percent of range is 50 percent.

3.2.3 Analog output

Field Comm. 1, 1, 3

Analog Output — 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 D/A Trim (Digital-to-Analog Trim).

Process Density is required only if you have designated mass units for your flow rate units. You
will first be prompted for density units. It is required for the conversion from volumetric units to
mass units. For example, if you have set flow units to kg/sec rather than gal/sec, a density is
required to convert the measured volumetric flow into the desired mass flow. The Fixed Process
Density must be entered even in temperature compensated Saturated Steam applications as
this value is used to determine flow sensor limits in Mass Flow Units.

Note

If mass 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 is calculated using this user-entered
density, and any error in this number will cause error in the mass flow measurement. If fluid
density is changing over time, it is recommended that volumetric flow units be used.

Primary Variable (PV)

Field Comm. 1, 3, 6, 1

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)

Field Comm. 1, 3, 6, 2

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)

Field Comm. 1, 3, 6, 3

Selections for this Variable are identical to those of the Secondary Variable.

Reference Manual

00809-0100-4860, Rev BC

Quaternary Variable (4V)

Field Comm. 1, 3, 6, 4

Selections for this Variable are identical to those of the Secondary Variable.

3.2.12 PV units

Field Comm. 1, 3, 7

Selections for this include all units available for the selection of PV. This will set the units for the
flow rate or process temperature.

3.2.13 Range values

Field Comm. 1, 3, 8

Range Values enables you to maximize resolution of 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.

42

Primary Variable Upper Range Value (PV URV)

Field Comm. 1, 3, 8, 1

This is the 20 mA set point for the meter.

Configuration

Reference Manual

00809-0100-4860, Rev BC

Primary Variable Lower Range Value (PV LRV)

Field Comm. 1, 3, 8, 2

This is the 4 mA set point for the meter, and is typically set to 0 when the PV is a Flow Variable.

3.2.14 PV damping

Field Comm. 1, 3, 9

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 Variable,
Percent of Range, and Vortex Frequency. This will not affect the Pulse Output, Total, or other
Digital Information.

The default damping value is 2.0 seconds. This can be reset 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.

Section 3: Configuration

January 2013

Note

If the vortex shedding frequency is slower than the damping value selected, no damping is
applied.

3.2.15 Auto adjust filter

Field Comm. 1,3, Scroll to

Bottom

The Auto Adjust Filter is 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 a stronger signal select a density
value that is lower than the actual flowing density.

This section contains information for advanced configuration parameters and diagnostics.

The software configuration settings for the Rosemount 8600D can be accessed through a
HART-based communicator or through a control system. The software functions for the Field
Communicator are described in detail in this section of the manual. It provides an overview and
summary of communicator functions. For more complete instructions, see the communicator
manual.

Before operating the Rosemount 8600D in an actual installation, you should review all of the
factory set configuration data to ensure that they reflect the current application.

Although the Rosemount 8600D performs continuous self-diagnostics, you can initiate an
immediate diagnostic to check for possible electronics failure.

Self Test checks proper communications with the transmitter and provides diagnostic
capabilities for transmitter problems. Follow on-screen instructions if problems are detected, or
check the appropriate appendix for error messages relating to your transmitter.

Reset transmitter

Field Comm. 1, 2, 1, 6

Restarts the transmitter - same as cycling power.

4.1.2 Loop test

Field Comm. 1, 2, 2

48

Loop Test verifies the output of the flowmeter, the integrity of the loop, and the operation of any
recorders or similar devices. Conduct the loop test after the flowmeter is installed in the field.

If the meter is located in a loop with a control system, the loop will have to be set to manual
control before the loop test is performed.

Loop Test allows the device to be set to any output between the Low Alarm and High Alarm.

Operation

Reference Manual

00809-0100-4860, Rev BC

4.1.3 Pulse output test

Field Comm. 1, 2, 3

Pulse Output Test is a fixed frequency mode test that checks the integrity of the pulse loop. It
tests that all connections are good and that the pulse output is running on the loop.

4.1.4 Flow simulation

Field Comm. 1, 2, 4

Flow Simulation enables you to check the electronics functionality. This can be verified with
either the Flow Simulation Internal or Flow Simulation External method. PV must be Volume
Flow, Velocity Flow, or Mass Flow before Flow Simulation can be used.

PV

Field Comm. 1, 2, 4, 1

Shows the flow value in current engineering units for the flow simulation.

Section 4: Operation

January 2013

Shedding frequency

Field Comm. 1, 2, 4, 2

Shows the shedding frequency for the flow simulation.

Configure flow simulation

Field Comm. 1, 2, 4, 3

Allows you to configure your flow simulation (internal or external).

Simulate flow internal

Field Comm. 1, 2, 4, 3, 1

When licensed, the simulate flow internal function will automatically electronically disconnect
the sensor and enable you to configure the internal flow simulation (fixed or varying).

Fixed flow

Field Comm. 1, 2, 4, 3, 1, 1

The fixed flow simulation signal can be entered in either a percent of range or flow rate in current
engineering units. This simulation locks the Vortex in to the specific flow rate entered.

Operation

Varying flow

Field Comm. 1, 2, 4, 3, 1, 2

The minimum and maximum flowrate can be entered in either percent of range or as a flow rate
in current engineering units. The ramp time can be entered in seconds from a minimum of 0.6
seconds to a maximum of 34951 seconds. This simulation causes the Vortex meter to
continuously ramp from the minimum entered rate to the maximum entered rate and back over
the ramp time.

49

Section 4: Operation

January 2013

Simulate flow external

Simulate flow external allows you to disconnect the sensor electronically so an external
frequency source can be used to test and verify the electronics.

Enable normal flow

Enable normal flow allows you to exit the flow simulation mode (internal or external) and return
to normal operation mode. Enabled Normal Flow must be activated after any simulation is run.
Failure to enable normal flow will leave the Vortex in simulation mode.

 Snsr Offln (flow simulation – external)

 Norm Flow (normal flow operation)

4.1.5 D/A trim

Field Comm. 1, 2, 5

D/A Trim (Digital-to-Analog Trim) enables you to check and trim the analog output in a single
function. If the analog output is trimmed, it will be scaled proportionally through the range of
the output.

To trim the digital-to-analog output, initiate the D/A Trim function and connect an ammeter to
the loop to measure the actual analog output of the meter. Follow the on-screen functions to
complete the task.

4.1.6 Scaled D/A trim

Field Comm. 1, 2, 6

Scaled D/A Trim enables you to calibrate the flowmeter analog output using a different scale
than the standard 4-20 mA output scale. Non-scaled D/A Trimming (described above), is
typically performed using an ammeter where calibration values are entered in units of
milliamperes. Both non-scaled D/A trimming and scaled D/A trimming allow you to trim the
4-20mA output to approximately ±5% of the nominal 4mA end point and ±3% of the nominal
20mA end point. Scaled D/A Trimming allows you to trim the flowmeter using a scale that may
be more convenient based upon your method of measurement.

50

For example, it may be more convenient for you to make current measurements by direct
voltage readings across the loop resistor. If your loop resistor is 500 Ohms, and you want to
calibrate the meter using voltage measurements made across this resistor, you could rescale
(select CHANGE on the 375) your trim points from 4-20 mA to 4-20 mA x 500 ohm or 2-10 Vdc.

Operation

Reference Manual

00809-0100-4860, Rev BC

Once your scaled trim points have been entered as 2 and 10, you can now calibrate your
flowmeter by entering voltage measurements directly from the voltmeter.

4.1.7 Shed freq at URV

Field Comm. 1, 2, 7

Shed Freq at URV function gives the shedding frequency corresponding to your URV (URV =
Upper Range Value). If the PV is Process Temperature, the Shedding Frequency at URV
represents the shedding frequency of the Volumetric Flow URV. This can be set by assigning
Volumetric Flow to PV and setting range values.

4.2 Advanced functionality

The Rosemount 8600D enables you to configure the flowmeter for a wider range of applications
and special situations. These functions are grouped as follows under Detailed Set-Up:

Section 4: Operation

4.3 Detailed set-up

Field Comm. 1, 4

 Characterize Meter

 Configure Outputs

 Signal Processing

 Device Information

4.3.1 Characterize meter

Field Comm. 1, 4, 1

The Meter Body variables provide configuration data that are unique to your Rosemount 8600D.
The settings of these variables can affect the compensated K-factor on which the primary
variable is based. This data is provided during factory configuration and should not be changed
unless the physical make-up of your Rosemount 8600D is changed.

K-factor

Field Comm. 1, 4, 1, 1

The Field Communicator provides information on Reference and Compensated K-factor values.

The Reference K-factor is factory set according to the actual K-factor for your application. It
should only be changed if you replace parts of the flowmeter. Contact your Rosemount
representative for details.

Operation

The Compensated K-factor is based on the reference K-factor as compensated for the given
process temperature, wetted materials, body number, and pipe ID. Compensated K-factor is an
informational variable that is calculated by the electronics of your flowmeter.

51

Section 4: Operation

January 2013

Mating pipe I.D.

The inside diameter of the pipe adjacent to the flow meter can cause entrance effects that may
alter flowmeter readings. The exact inside diameter of the pipe must be specified to correct for
these effects. Enter the appropriate value for this variable.

Mating Pipe ID values for schedule 10, 40, 80, and 160 piping are given in Table 3-1 on page 41.
If the piping in your application is not one of these, you may need to contact the manufacturer
for exact Pipe ID.

Flange type

Flange Type enables you 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.

Meter body number

Field Comm. 1, 4, 1, 5

Meter Body Number is a factory set configuration variable that stores the body number of your
particular flowmeter and the type of construction. The meter body number is found to the right
of the body number on the meter body tag, which is attached to the bracket of the meter body.

The format of this variable is a number followed by an alpha character. The number designates
the body number.

Installation effect

52

Field Comm. 1, 4, 1, 6

Installation Effect enables you to compensate the flowmeter for installation effects caused by
less than ideal straight run piping. See reference graphs located in Technical Data Sheet
00816-0100-3250 for the percent of K-factor shift based on entrance effects of upstream
disturbances. This value is entered as a percentage of the range of -1.5% to +1.5%.

Operation

Reference Manual

00809-0100-4860, Rev BC

4.3.2 Configure outputs

Field Comm. 1, 4, 2

The Rosemount 8600D is digitally adjusted at the factory using precision equipment to ensure
accuracy. You should be able to install and operate the flowmeter without a D/A Trim.

Analog output

Field Comm. 1, 4, 2, 1

For maximum accuracy, calibrate the analog output and, if necessary, trim for your system loop.
The D/A Trim procedure alters the conversion of the digital signal into an analog 4–20 mA
output.

Range values

Field Comm. 1, 4, 2, 1, 1

Range Values enables you to maximize resolution of 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.

Section 4: Operation

January 2013

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.

Loop test

Field Comm. 1, 4, 2, 1, 2

Loop Test verifies the output of the flowmeter, the integrity of the loop, and the operation of any
recorders or similar devices. Conduct the loop test after the flowmeter is installed in the field. If
the meter is located in a loop with a control system, the loop will have to be set to manual
control before the loop test is performed.

Loop Test allows the device to be set to any output between the Low Alarm and High Alarm.

Alarm jumper

Field Comm. 1, 4, 2, 1, 3

Alarm Jumper lets you verify the alarm jumper setting.

D/A trim (Digital-to-Analog trim)

Field Comm. 1, 4, 2, 1, 4

Digital-to-Analog Trim enables you to check and trim the analog output in a single function. If
the analog output is trimmed, it will be scaled proportionally through the range of the output.
To trim the digital-to-analog output, initiate the D/A Trim function and connect an ammeter to
the loop to measure the actual analog output of the meter. Follow the on-screen functions to
complete the task.

Scaled D/A trim

Scaled D/A Trim enables you to calibrate the flowmeter analog output using a different scale
than the standard 4-20 mA output scale. Non-scaled D/A Trimming (described above), is
typically performed using an ammeter where calibration values are entered in units of
milliamperes. Both non-scaled D/A trimming and scaled D/A trimming allow you to trim the
4-20mA output to approximately ±5% of the nominal 4mA end point and ±3% of the nominal
20mA end point. Scaled D/A Trimming allows you to trim the flowmeter using a scale that may
be more convenient based upon your method of measurement.

For example, it may be more convenient for you to make current measurements by direct
voltage readings across the loop resistor. If your loop resistor is 500 Ohms, and you want to
calibrate the meter using voltage measurements made across this resistor, you could rescale
your trim points from 4-20mA to 4-20mA x 500 ohm or 2-10 Vdc. Once your scaled trim points
have been entered as 2 and 10, you can now calibrate your flowmeter by entering voltage
measurements directly from the voltmeter.

Pulse output

The Rosemount 8600D comes with an optional pulse output option (P). This enables the
flowmeter to output the pulse rate to an external control system, totalizer, or other device. If the
flowmeter was ordered with the pulse mode option, it may be configured for either pulse
scaling (based on rate or unit) or shedding frequency output. There are four methods for
configuring the pulse output:

 Off

 Direct (Shedding Frequency)

 Scaled Volume

 Scaled Velocity

 Scaled Mass

Direct (shedding frequency)

This mode provides the vortex shedding frequency as output. In this mode, the software does
not compensate the K-factor for effects such as thermal expansion or differing mating pipe
inside diameters. Scaled pulse mode must be used to compensate the K-factor for thermal
expansion and mating pipe effects.

Scaled volume

Field Comm. 1, 4, 2, 2, 1, 3

This mode allows you to configure the pulse output based on a volumetric flow rate. For
example, set 100 gallons per minute = 10,000 Hz. (The user enterable parameters are flow rate
and frequency.)

Pulse scaling rate

Field Comm. 1, 4, 2, 2, 1, 3, 1

Pulse scaling rate allows the user to set a certain volume flow rate to a desired Frequency.

Pulse output test

Pulse Output Test is a fixed frequency mode test that checks the integrity of the pulse loop. It
tests that all connections are good and that pulse output is running on the loop.

HART output

Multidrop configuration refers to the connection of several flowmeters to a single
communications transmission line. Communication occurs digitally between a HART-based
communicator or control system and the flowmeters. Multidrop mode automatically
deactivates the analog output of the flowmeters. Using the HART communications protocol, up
to 15 transmitters can be connected on a single twisted pair of wires or over leased phone lines.

The use of a multidrop installation requires consideration of the update rate necessary from
each transmitter, the combination of transmitter models, and the length of the transmission
line. Multidrop installations are not recommended where intrinsic safety is a requirement.
Communication with the transmitters can be accomplished with commercially available Bell
202 modems and a host implementing the HART protocol. Each transmitter is identified by a
unique address (1-15) and responds to the commands defined in the HART protocol.

Note

The Rosemount 8600D is set to poll address zero at the factory, allowing it to operate in the
standard point-to-point manner with a 4–20 mA output signal. To activate multidrop
communication, the transmitter poll address must be changed to a number between 1 and 15.
This change deactivates the 4–20 mA analog output, setting it to 4 mA, and disables the failure
mode alarm signal.

Operation

Poll address

Poll Address enables you to set the poll address for a multi-dropped meter. The poll address is
used to identify each meter on the multi-drop line. Follow the on-screen instructions to set the
address at a number from 1 to 15. To set or change the flowmeter address, establish
communication with the selected Rosemount 8600D in the loop.

Auto poll

When a HART-based communicator is powered up and auto polling is on, the communicator
automatically polls the flowmeter addresses to which it is connected. If the address is 0, the
HART-based communicator enters its normal online mode. If it detects an address other than 0,
the communicator finds each device in the loop and lists them by poll address and tag. Scroll
through the list and select the meter with which you need to communicate.

If Auto Poll is off, the flowmeter must have the poll address set to 0 or the flowmeter will not be
found. If a single connected device has an address other than zero and auto polling is off, the
device will not be found either.

4.3.3 Signal processing

Field Comm. 1, 4, 3

The Rosemount 8600D and its HART-based communications feature enable you to filter out
noise and other frequencies from the transmitter signal. The four user-alterable parameters
associated with the digital signal processing on the Rosemount 8600D include low-pass filter
corner frequency, low-flow cutoff, trigger level, and damping. These four signal conditioning
functions are configured at the factory for optimum filtering over the range of flow for a given
line size and service type (liquid or gas). For most applications, leave these parameters at the
factory settings. Some applications may require adjustment of the signal processing
parameters.

Use signal processing only when recommended in the Troubleshooting section of this manual.
Some of the problems that may require signal processing include:

 High output (output saturation)

 Erratic output with or without flow present

 Incorrect output (with known flow rate)

 No output or low output with flow present

60

 Low total (missing pulses)

 High total (extra pulses)

Operation

Reference Manual

00809-0100-4860, Rev BC

If one or more of these conditions exist, and you have checked other potential sources (K-factor,
service type, lower and upper range values, 4–20mA trim, pulse scaling factor, process
temperature, pipe ID), refer to Section 5: Troubleshooting. Remember that the factory default
settings can be re-established at any time with Filter Restore. If problems persist after signal
processing adjustments, consult the factory.

Optimize flow range

The Optimize Flow Range function will automatically set the 8600D filter levels, Low Flow Cutoff
(LFC), Trigger Level, and Low Pass Corner Frequency, to optimum settings based on the process
density and process fluid type.

Primary Variable (PV)

PV is the actual measured variable rate in the line. On the bench, the PV value should be zero.
Check the units on the PV to make sure they are configured correctly. See PV Units if the units
format is not correct. Use the Process Variable Units function to select the units for
your application.

Signal/trigger level ratio (Sig/Tr)

Field Comm. 1, 4, 3, 1, 3

The Signal to Trigger Level Ratio is a variable that indicates the flow signal strength to trigger
level ratio. This ratio indicates if there is enough flow signal strength for the meter to work
properly. For accurate flow measurement, the ratio should be greater than 4:1. Values greater
than 4:1 will allow increased filtering for noisy applications. For ratios greater than 4:1, with
sufficient density, the Auto Adjust Filter function can be utilized to optimize the measurable
range of the flowmeter.

Ratios less than 4:1 may indicate applications with very low densities and/or applications with
excessive filtering.

Auto adjust filter

Field Comm. 1, 4, 3, 1, 4

The Auto Adjust Filter is 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. For a
stronger signal select a density value that is lower than the actual flowing density.

PV is the actual measured variable. Check the units on the PV to make sure they are configured
correctly. See PV Units if the units format is not correct. Use the Process Variable Units function
to select the units for your application.

Signal/trigger level ratio (Sig/Tr)

The Signal to Trigger Level Ratio is a variable that indicates the flow signal strength to trigger
level ratio. This ratio indicates if there is enough flow signal strength for the meter to work
properly. For accurate flow measurement, the ratio should be greater than 4:1. Values greater
that 4:1 will allow increased filtering for noisy applications. For ratios greater than 4:1, with
sufficient density, the Optimize Flow Range function can be utilized to optimize the measurable
range of the flowmeter.

Low flow cutoff

Field Comm. 1, 4, 3, 2, 3

Low Flow Cutoff enables you to adjust the filter for noise at no flow. It is set at the factory to
handle most applications, but certain applications may require adjustment either to expand
measurability or to reduce noise.

The Low Flow Cutoff offers two modes for adjustment:

 Increase Range

 Decrease No Flow Noise

It also includes a dead band such that once flow goes below the cutoff value, output does not
return to the normal flow range until flow goes above the dead band. The dead band extends to
approximately 20 percent above the low flow cutoff value. The dead band prevents the output
from bouncing between 4mA and normal flow range if the flow rate is near the low flow cutoff
value.

Low pass filter

Field Comm. 1, 4, 3, 2, 4

62

The Low Pass Filter sets the low-pass filter corner frequency to minimize the effects of high
frequency noise. It is factory set based
on line size and service type. Adjustments may be required only if
you are experiencing problems. See Section 5: Troubleshooting.

Operation

Reference Manual

00809-0100-4860, Rev BC

The Low Pass Filter corner frequency variable offers two modes for adjustment:

 Increase filtering

 Increase sensitivity

Trigger level

Trigger Level is configured to reject noise within the flow range while allowing normal amplitude
variation of the vortex signal. Signals of amplitude lower than the Trigger Level setting are
filtered out. The factory setting optimizes noise rejection in most applications. Trigger Level
offers two modes for adjustment:

 Increase filtering

 Increase sensitivity

The electronics is capable of internally generating a flow signal that may be used to simulate a
sensor signal to perform electronics verification with a Handheld Communicator or AMS
interface. The simulated signal amplitude is based on the transmitter required minimum
process density. The signal being simulated can be one of several profiles – a simulated signal of
constant frequency or a simulated signal representative of a ramping flow rate. The electronics
verification procedure is described in detail in Appendix C: Electronics verification. To verify the
electronics, you can input a frequency on the “TEST FREQ IN” and “GROUND” pins to simulate
flow via an external signal source such as a frequency generator. To analyze and/or troubleshoot
the electronics, an oscilloscope (set for AC coupling) and a Handheld Communicator or AMS
interface are required. Figure 5-2 is a block diagram of the signal as it flows from the sensor to
the microprocessor in the electronics.
