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 shredder 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 Vortex Flowmeter.

2.1 Review

Configuration

00809-0100-4860, Rev BF

FastKeys

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.

2.2.1 Primary Variable (PV)

Reference Manual

00809-0100-4860, Rev BF

FastKeys

The measured value of the variable mapped to the primary variable. This can be either Process Temperature (MTA option only) or Flow. Flow variables are available as mass, volume, 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 4. Use the Process Variable Units function to select the units for your

application.

2.2.2 PV% of range

FastKeys

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.

2.2.3 Analog output

FastKeys

The analog output variable provides the analog value for the primary variable. The analog output refers to the industry standard output in the 4–20 mA range. Check the analog output value against the actual loop reading given by a multi-meter. If it does not match, a 4–20 mA trim is required. See D/A Trim (Digital-to-Analog Trim).

Special units

FastKeys

1, 1, 4, 1, 3

Special Units allows you to create flow rate units that are not among the standard options. They can be volumetric only. Configuration of a special unit involves entry of these values: base volume unit, base time unit, user defined unit and conversion number. Suppose you want the Rosemount 8600D to display flow in barrels per minute instead of gallons per minute, and one barrel is equal to 31.0 gallons.

 Base volume unit: gal

 Base time unit: min

 User defined unit: br

 Conversion number:

/31.0

See the specific variables listed below for more information on setting special units.

Base volume unit

FastKeys

Base Volume Unit is the unit from which the conversion is made. You must select one of the Field Communicator defined unit options:

 Gallons (gal)

Density/Density ratio

FastKeys

When configuring a meter for mass flow units, a density value needs to be entered. When configuring a meter for Standard and Normal Volumetric flow units a density ratio will be required.

1, 3, 2, 4

Density ratio

FastKeys

Configure the Density Ratio in one of two ways:

1. Enter Density Ratio to convert from actual flow rate to standard flow rate.

2. Enter the process and base conditions. (The Rosemount 8600D electronics will then calculate the density ratio for you).

Note

Be careful to calculate and enter the correct conversion factor. Standard flow is calculated with the conversion factor you enter. Any error in the factor entered will result in an error in the standard flow measurement. If pressure and temperature changes over time, use actual volumetric flow units. The Rosemount 8600D does not compensate for changing temperature and pressure.

Note

Changing the base process conditions will modify the density ratio. Likewise a change to the density ratio will lead to a change in the base process pressure (Pf).

Fixed process density

FastKeys

1, 3, 2, 4, 2

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.

2.3.3 Reference K-factor

2.3.8 Range values

FastKeys

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.

FastKeys

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

2.3.9 PV damping

FastKeys

Damping changes the response time of the flowmeter to smooth variations in output readings caused by rapid changes in input. Damping is applied to the Analog Output, Primary 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.

Note

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

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.

3.2 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 AMS signal loop in accordance with the specifications for your communicator.

3.2.1 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.

3.2.2 Flowmeter sizing

™

Device Manager (or other communications device) to the

Installation

00809-0100-4860, Rev BF

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: Specifications and 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:

Specifications and Reference Data for sizing data.

Contact your local Rosemount Inc. sales representative to obtain a copy of Instrument

Toolkit vortex sizing module will calculate valid flowmeter sizes based on user-supplied application information.

which contains a sizing module for the Rosemount 8600D Vortex flowmeter. The

3.2.3 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.

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 the meter body remains full, avoid downward vertical liquid flows where back pressure is inadequate.

Reference Manual

00809-0100-4860, Rev BF

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 shredder 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 3-2. Insulation may be required around the pipe to maintain an electronics temperature below 185 °F (85 °C).

Figure 3-2. Examples of High-Temperature Installations

electronics below the pipe.

(ACCEPTABLE ORIENTATION)

Steam installations

For steam applications, avoid installations such as the one shown in Figure 3-3. Such installations may cause a water-hammer condition at start-up due to trapped condensate. The high force from the water hammer can overstress the sensing mechanism and cause permanent damage to the sensor.

Figure 3-3. Avoid This Type of Installation for Steam Applications

Rosemount 8600 Vortex Flow Meter

Reference Manual

Installation

00809-0100-4860, Rev BF

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 50).

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 3-4.

3.2.4 Wetted material selection

Ensure 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.

3.2.5 Environmental considerations

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.

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.

Reference Manual

00809-0100-4860, Rev BF

3.3 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.

3.4 Hardware configuration

The hardware jumpers on the Rosemount 8600D enable you to set the alarm and security. (See Figure 3-5.) 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 3-6 on page 28.)

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.

Rosemount 8600 Vortex Flow Meter

Reference Manual

May 2019

Installation

00809-0100-4860, Rev BF

Set these jumpers during the commissioning stage to avoid exposing the electronics to the plant environment.

Figure 3-5. Alarm and Security Jumpers

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.

3.4.1 Failure mode vs. saturation output values

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.

00809-0100-4860, Rev BF

Note

Do not lift the flowmeter by the transmitter. Lift the meter by the meter body. If necessary, Lifting supports can be tied around the meter body as shown in Figure 3-7.

Figure 3-7. Lifting Supports

3.5.2 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.

3.5.3 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.

3.5.5 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 3-9.

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.

3.5.6 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.

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.

3.6 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: Specifications and Reference Data, “Dimensional drawings”

on page 97 for dimensional information.

3.6.1 High-Temperature installations

Install the meter body so the electronics are positioned to the side of or below the pipe as shown in Figure 3-2 on page 24. 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.

3.6.2 Conduit connections

Reference Manual

00809-0100-4860, Rev BF

The electronics housing has two ports for 1/2–14 NPT or M2031.5 conduit connections. Unless marked otherwise conduit entries in the housing are made 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. 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.

3.6.3 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.

3.6.5 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 44 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.

Installation

00809-0100-4860, Rev BF

3.6.6 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 3-11 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 3-11 as a quick reference.

Loop resistance specification:

If HART communication is required, a minimum resistance of 250Ω 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.

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.

Note

When using pulse output, be sure to follow these precautions:

 Shielded twisted pair is required when the pulse output and 4–20 mA output are

run in the same conduit or cable trays. Shielded wire will also reduce false triggering caused by noise pickup. Wiring should be 24 AWG or larger and not exceed 5,000 ft. (1500 m).

 Do not connect the powered signal wiring to the test terminals. Power could

damage the test diode in the test connection.

 Do not run signal wiring in conduit or open trays with power wiring or near heavy

electrical equipment. If needed, ground signal wiring at any one point on the signal loop, such as the negative terminal of the power supply. The electronics housing is grounded to the meter body.

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

FastKeys

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.

1, 2, 5

4.1.6 Scaled D/A trim

FastKeys

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 (select CHANGE on the 375) your trim points from 4-20 mA to 4-20 mA 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.

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

FastKeys

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.

HART output

FastKeys

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.

Figure 4-1 shows a typical multi-drop network. This figure is not intended as an installation

diagram. Contact Rosemount product support with specific requirements for multi-drop applications.

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.

Poll address

FastKeys

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

FastKeys

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

Operation

00809-0100-4860, Rev BF

FastKeys

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

 Low total (missing pulses)

 High total (extra pulses)

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

FastKeys

Automatically sets 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.

Signal/trigger level ratio (Sig/Tr)

FastKeys

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.

1, 4, 3, 1, 3

Auto adjust filter

FastKeys

A function that can be used to optimize the range of the flowmeter based on the density of the fluid. The electronics uses process density to calculate the minimum measurable flow rate, while retaining at least a 4:1 signal to the trigger level ratio. This function will also reset all of the filters to optimize the flowmeter performance over the new range. For a stronger signal select a density value that is lower than the actual flowing density.

Low flow cutoff

FastKeys

1, 4, 3, 2, 3

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

FastKeys

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.

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

1, 4, 3, 2, 4

 Increase filtering

 Increase sensitivity

Trigger level

FastKeys

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

Note

Do not adjust this parameter unless directed to do so by a Rosemount Technical Support Representative.

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.

------------------------------=

f Q



where:

PPL = Permanent Pressure loss (psi or kPa)

Where:

= Density at operating conditions (lb/ft3 or kg/m3)

Q = Actual volumetric flow rate (Gas = ft

/min or m3/hr;

Liquid = gal/min or l/min)

D = Flowmeter bore diameter (in. or mm)

A = Constant depending on meter style, fluid type and

flow units. Determined per following table:

Minimum upstream pressure (Liquids)

Flow metering conditions that would allow cavitation, the release of vapor from a liquid, should be avoided. This flow condition can be avoided by remaining within the proper flow range of the meter and by following appropriate system design.

For some liquid applications, incorporation of a back pressure valve should be considered. To prevent cavitation, the minimum upstream pressure should be:

P = 2.9P + 1.3p

or P = 2.9P + pv + 0.5 psia (3.45

kPa) (use the smaller of the two results)

P = Line pressure five pipe diameters downstream of the

meter (psia or kPa abs)

P = Pressure loss across the meter (psi or kPa)

= Liquid vapor pressure at operating conditions (psia or

kPa abs)

Failure mode alarm

HART analog

If self-diagnostics detect a gross flowmeter failure, the analog signal will be driven to the values below:

Low 3.75 High 21.75 NAMUR Low 3.60 NAMUR High 22.6

High or low alarm signal is user-selectable through the fail mode alarm jumper on the electronics. NAMUR-compliant alarm limits are available through the C4 or CN Option. Alarm type is field configurable also.

Saturation output values

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. The NAMUR-Compliant Saturation Values are available through the C4 or CN option. Saturation type is field configurable.

Low 3.9 High 20.8 NAMUR Low 3.8 NAMUR High 20.5

Reference Manual

00809-0100-4860, Rev BF

Damping

Flow Damping adjustable between 0.2 and 255 seconds.

Process Temperature Damping adjustable between 0.4 and 32 seconds (MTA Option Only).

Response time

Three vortex shedding cycles or 300 ms, whichever is greater, maximum required to reach 63.2% of actual input with the minimum damping (0.2 seconds).

Turn-on time

HART analog

Less than four (4) seconds plus the response time to rated accuracy from power up (less than 7 seconds with the MTA Option).

Transient protection

The transient terminal block meets the following specifications: IEEE C62.41 - 2002 Category B 3 kA crest (8 3 20 s) 6 kV crest (1.2 3 50 s) 6 kV/0.5 kA (0.5 s, 100 kHz, ring wave)

Overrange capability

HART analog

Analog signal output continues to 105 percent of span, then remains constant with increasing flow. The digital and pulse outputs will continue to indicate flow up to the upper sensor limit of the flowmeter and a maximum pulse output frequency of 10400 Hz.

Flow calibration

Meter bodies are flow-calibrated and assigned a unique calibration factor (K-factor) at the factory. The calibration factor is entered into the electronics, enabling interchangeability of electronics and/or sensors without calculations or compromise in accuracy of the calibrated meter body.

A.3 Typical flow ranges

Tables A-5 through A-12 show typical flow ranges for some common process fluids with default filter settings. Consult your local sales representative to obtain a computer sizing program that describes in greater detail the flow range for an application.

Security lockout

When the security lockout jumper is enabled, the electronics will not allow you to modify parameters that affect flowmeter output.

Output testing

Current source

Flowmeter may be commanded to set the current to a specified value between 4 and 20 mA.

Frequency source

Flowmeter may be commanded to set the frequency to a specified value between 0 and 10000 Hz.

Low flow cutoff

Adjustable over entire flow range. Below selected value, output is driven to 4 mA and zero pulse output frequency.

Humidity limits

Operates in 0–95% relative humidity under non-condensing conditions (tested to IEC 60770, Section

6.2.11).
