4 Pre-installation

4.1 Planning

For a successful installation, consider each aspect of your application and the meter you are installing.

4.1.1 Sizing

To determine the correct meter size for optimal flow meter performance:
Determine the limits of measuring flow.
Determine the process conditions so that they are within the stated
requirements for Reynolds number and velocity.
For sizing details, refer to the product reference manual.
Sizing calculations are required to select the proper flow meter size. These calculations provide pressure loss, accuracy, and minimum and maximum flow rate data to guide in proper selection. Vortex sizing software can be found using the Selection and Sizing tool. The Selection and Sizing tool can be accessed online or downloaded for offline use using this link:
www.Emerson.com/FlowSizing.

4.1.2 Wetted material selection

Ensure that the process fluid is compatible with the meter body wetted materials when specifying the Rosemount 8800D. Corrosion will shorten the life of the meter body. Consult recognized sources of corrosion data or contact Emerson Flow Sales Representative for more information.
Note
If Positive Material Identification (PMI) is required, perform test on a machined surface.

4.1.3 Orientation

The best orientation for the meter depends on the process fluid, environmental factors, and any other nearby equipment.
Vertical installation
Vertical, upward, installation allows upward process liquid flow and is generally preferred. Upward flow ensures that the meter body always remains full and that any solids in the fluid are evenly distributed.
The meter can be mounted in the vertical down position when measuring gas or steam flows. This type of application is strongly discouraged for liquid flows, although it can be done with proper piping design.

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

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

4.1.4 Location

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

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

4.1.6 Power supply (FOUNDATION fieldbus)

The flowmeter requires 9-32 Vdc at the power terminals. Each fieldbus power supply requires a power conditioner to decouple the power supply output from the fieldbus wiring segment.

4.2 Commissioning

For proper configuration and operation, commission the meter before putting it into operation. Bench commissioning also enables you to check hardware settings, test the flowmeter electronics, verify flowmeter configuration data, and check output variables. Any problems can be corrected—or configuration settings changed—before going out into the installation environment. To commission on the bench, connect a configuration device to the signal loop in accordance the device instructions.
(20 °C) equivalent

4.2.1 HART jumper configuration

Two jumpers on the transmitter specify the alarm and security modes. Set these jumpers during the commissioning stage to avoid exposing the electronics to the plant environment. The two jumpers can be found on the electronics board stack or on the LCD meter.
Alarm
Security
Quick Start Guide 15
As part of normal operations, the transmitter continuously runs a self-diagnostic routine. If the routine detects an internal failure in the electronics, flow meter output is driven to a low or high alarm level, depending on the position of the failure mode jumper. The factory sets the jumper according to the Configuration Data Sheet, if applicable, or HI by default.
You can protect the configuration data with the security lockout jumper. With the security lockout jumper ON, any configuration changes attempted on the electronics are disallowed. You can still access and review any of the operating parameters and scroll
through the available parameters, but no changes can be made. The factory sets the jumper according to the Configuration Data Sheet, if applicable, or OFF by default.
Note
If you will be changing configuration variables frequently, it may be useful to leave the security lockout jumper in the OFF position to avoid exposing the flow meter electronics to the plant environment.
To access the jumpers, remove the transmitter electronics housing or the LCD cover (if equipped) opposite of the terminal blocks, See Figure 4-8 and
Figure 4-9.

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. The saturation and alarm levels are software selectable between Rosemount Standard and NAMUR levels.
Table 4-2: Analog output: standard alarm values vs. saturation values
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

Level 4–20 mA saturation value 4–20 mA alarm value
Low 3.8 mA ≤ 3.6 mA
High 20.5 mA ≥ 22.6 mA
Quick Start Guide 17

4.2.2 FOUNDATION fieldbus jumper configuration

Two jumpers on the transmitter specify the simulation and security modes. Set these jumpers during the commissioning stage to avoid exposing the electronics to the plant environment. The two jumpers can be found on the electronics board stack or on the LCD meter.
Simulate
The simulate enable jumper is used in conjunction with the Analog Input (AI) function block simulation. The jumper is also used as a lock-out feature for the AI function block. To enable the simulate enable feature, the jumper must transition from OFF to ON after power is applied to the transmitter, preventing the transmitter from being accidentally left in simulator mode. The factory sets the jumper to OFF by default.
Security
You can protect the configuration data with the security lockout jumper. With the security lockout jumper ON, any configuration changes attempted on the electronics are disallowed. You can still access and review any of the operating parameters and scroll through the available parameters, but no changes can be made. The factory sets the jumper to OFF by default.
To access the jumpers, remove the transmitter LCD cover (if equipped) or the electronics housing cover opposite of the terminal blocks, See Figure
4-10 and Figure 4-11.
18 Rosemount™ 8800D Series Vortex Flow Meter
Installation
May 2019
The hardware jumpers on the flowmeter enable you to set the fieldbus simulate enable and transmitter security (see Figure 3-19). To access the jumpers, remove the electronics housing cover from the end of the flowmeter. If the flowmeter does not include an LCD display, the jumpers are accessible by removing the cover on the electronics side. If the flowmeter includes an LCD display option, the fieldbus simulate enable and security jumpers are found on the face of the LCD display (see Figure 3-20).
Note
If you will be changing configuration variables frequently, leave the security lockout jumper in the OFF position to avoid exposing the flowmeter electronics to the plant environment.
Set jumpers during the commissioning stage to avoid exposing the electronics to the plant environment.

After you configure the transmitter, you may want to protect the configuration data from unwarranted changes. Each transmitter is equipped with a security jumper that can be positioned ON to prevent the accidental or deliberate change of configuration data. The jumper is located on the front side of the electronics module and is labeled SECURITY (see
Figure 3-19).
If your electronics are equipped with the LCD display (Option M5), the fieldbus simulate enable and transmitter security jumpers are located on the face of the indicator as shown in

5 Basic installation

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.
NOTICE
To avoid damage to the meter, do not lift the flow meter by the transmitter. Lift the meter by the meter body. Lifting supports can be tied around the meter body as shown.
Figure 5-1: Lifting supports

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.
5.3
Quick Start Guide 21

Gaskets

The flow meter requires gaskets supplied by the user. Be sure to select gasket material that is compatible with the process fluid and pressure ratings of the specific installation.
Note
Ensure the inside diameter of the gasket is larger than the inside diameter of the flow meter and adjacent piping. If gasket material extends into the flow stream, it will disturb the flow and cause inaccurate measurements.

5.4 Insulation

Insulation should extend to the end of the bolt on the bottom of the meter body and should leave at least 1-in. (25 mm) of clearance around the electronics bracket. The electronics bracket and electronics housing should not be insulated. See #unique_12/unique_12_Connect_42_Insulation.
Figure 5-2: Insulation best practice to prevent electronics overheating
CAUTION
To avoid damage to electronics in high temperature installations, and for both integral and remote electronics, only insulate the meter body as shown, do not insulate the area around the electronics.
5.5
22 Rosemount™ 8800D Series Vortex Flow Meter

Flanged-style flow meter mounting

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

Wafer-style flow meter alignment and mounting

Center the wafer-style meter body inside diameter with respect to the inside diameter of the adjoining upstream and downstream piping. This will ensure the flow meter achieves its specified accuracy. Alignment rings are provided with each wafer-style meter body for centering purposes. Follow these steps to align the meter body for installation. Refer to Figure 5-5.
1. Place the alignment rings over each end of the meter body.
2. Insert the studs for the bottom side of the meter body between the pipe flanges.
3. Place the meter body (with alignment rings) between the flanges.
Make sure the alignment rings are properly placed onto the
studs.
Align the studs with the markings on the ring that correspond to
the flange you are using.
If a spacer is used, see the product reference manual.
Note
Be sure to align the flow meter so the electronics are accessible, the conduits drain, and the flow meter is not subject to direct heat.
4. Place the remaining studs between the pipe flanges.
5. Tighten the nuts in the sequence shown in Figure 5-4.
6. Check for leaks at the flanges after tightening the flange bolts.
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 ASME PCC-1 for proper bolt tightening. Make sure the flow meter is centered between flanges of the same nominal size as the flow meter.

5.7 Cable glands

If you are using cable glands instead of conduit, follow the cable gland manufacturer’s instructions for preparation and make the connections in a conventional manner in accordance with local or plant electrical codes. Be sure to properly seal unused ports to prevent moisture or other contamination from entering the terminal block compartment of the electronics housing.

5.8 Flow meter grounding

Grounding is not required in typical vortex applications; however, a proper ground will eliminate possible noise pickup by the electronics. Grounding straps may be used to ensure that the meter is grounded to the process piping. If you are using the transient protection option (T1), grounding straps are required to provide a proper low impedance ground.
Note
Properly ground flow meter body and transmitter per the local code.
To use grounding straps, secure one end of the grounding strap to the bolt extending from the side of the meter body and attach the other end of each grounding strap to a suitable ground. See Figure 5-6.
Quick Start Guide 27

A. Internal ground connection B. External ground assembly

5.9 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
External Ground Assembly
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
28 Rosemount™ 8800D Series Vortex Flow Meter
The Internal Ground Connection screw is inside the FIELD TERMINALS side of the electronics housing. This screw is identified by a ground symbol ( ), and is standard on all Rosemount 8800D transmitters.
This assembly is located on the outside of the electronics housing and is included with the optional transient protection terminal block (Option Code T1). The External Ground Assembly can also be ordered with the transmitter (Option Code V5) and is automatically included with certain hazardous area approvals. See
Figure 5-6 for the location of the external ground
assembly.
transmitter case is properly grounded. For transient terminal block grounding, see the Reference Manual. Use the above guidelines to ground the transmitter case. Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive electric current if a lightning strike occurs.

5.10 Conduit installation

Prevent condensation in any conduit from flowing into the housing by mounting the flowmeter at a high point in the conduit run. If the flowmeter is mounted at a low point in the conduit run, the terminal compartment could fill with fluid.
If the conduit originates above the flowmeter, route conduit below the flowmeter before entry. In some cases a drain seal may need to be installed.

Wiring

The signal terminals are located in a compartment of the electronics housing separate from the flow meter electronics. Connections for a configuration tool and an electric current test connection are above the signal terminals.
Note
A power disconnect is required to remove power from the transmitter for maintenance, removal, and replacement.

Twisted pairs are required to minimize noise pickup in the 4–20 mA signal and digital communication signal. For high EMI/RFI environments, shielded signal wire is required and recommended in all other installations. To ensure
A
communication, wiring should be 24 AWG (0.205 mm²) or larger, and not exceed 5,000 ft (1500 m).

5.11.1 Analog output

The flow meter provides a 4–20 mA dc isolated electric current output, linear with the flow rate. To make connections, remove the FIELD TERMINALS side cover of the electronics housing. All power to the electronics is supplied over the 4–20 mA signal wiring. Connect the wires as shown.
Note
Twisted pairs are required to minimize noise pickup in the 4–20 mA signal and digital communication signal. For high EMI/RFI environments, shielded signal wire is required and recommended in all other installations. To ensure communication, wiring should be 24 AWG or larger, and not exceed 5,000 ft (1500 m).

5.11.2 FOUNDATION fieldbus wiring

Each fieldbus power supply requires a power conditioner to decouple the power supply output from the fieldbus wiring segment.
All power to the transmitter is supplied over the segment wiring. Use shielded, twisted pair for best results. For new installations or to get maximum performance, twisted pair cable designed especially for fieldbus should be used. Table 5-3 lists the cable characteristics and ideal specifications.
30 Rosemount™ 8800D Series Vortex Flow Meter
Table 5-3: Ideal cable specifications for fieldbus wiring
Characteristic Ideal specification
Impedance 100 Ohms ±20% at 31.25 kHz
Wire size 18 AWG (0.8 mm2)
Shield coverage 90%
Attenuation 3 db/km
Capacitive unbalance 2 nF/km
Note
The number of devices on a fieldbus segment is limited by the power supply voltage, the resistance of the cable, and the amount of current drawn by each device.
Transmitter wiring connection
To make the transmitter wiring connection, remove the FIELD TERMINALS end cover on the electronics housing. Connect the power leads to the positive (+) and negative (–) terminals. The power terminals are polarity insensitive: the polarity of the DC power leads does not matter when connecting to the power terminals. When wiring to screw terminals, crimped lugs are recommended. Tighten the terminals to ensure adequate contact. No additional power wiring is required.

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

5.12.3 Housing rotation

The entire electronics housing may be rotated in 90° increments for easy viewing. Use the following steps to change the housing orientation,
1. Loosen the three housing rotation set screws at the base of the electronics housing with a 5/32” hex wrench by turning the screws clockwise (inward) until they clear the support tube.
2. Slowly pull the electronics housing out of the support tube.
CAUTION
Do not pull the housing more than 1.5 in. (40 mm) from the top of the support tube until the sensor cable is disconnected. Damage to the sensor may occur if this sensor cable is stressed.
3. Unscrew the sensor cable from the housing with a 5/16” open end wrench.
4. Rotate the housing to the desired orientation.
5. Hold it in this orientation while you screw the sensor cable onto the base of the housing.
Quick Start Guide 35
CAUTION
Do not rotate the housing while the sensor cable is attached to the base of the housing. This will stress the cable and may damage the sensor.
6. Place the electronics housing into the top of the support tube.
7. Use a hex wrench to turn the three housing rotation screws counter­clockwise (outward) to engage the support tube.

6 Basic configuration

The transmitter must be configured for certain basic variables in order to be operational. In most cases, all of these variables are pre-configured at the factory. Configuration may be required if your transmitter is not configured or if the configuration variables need revision. The basic setup section includes parameters typically required for basic operation.
Note
ProLink III paths are only applicable to HART devices. For more information on Fieldbus devices, refer to the 8800D product manual for Fieldbus protocol (00809-0100-4772).

6.1 Process variables

Process variables define the flow meter output. When commissioning a flow meter, review each process variable, its function and output, and take corrective action if necessary before using the flow meter in a process application.

6.1.1 Primary variable mapping

Allows the user to select which variables the transmitter will output.
ProLink III Device Tools Configuration Communications
Note
The Primary Variable is also the Analog Output variable.
This can be either Process Temperature (MTA or MCA option only) or Flow. Flow variables are available as Corrected Volume Flow, Mass Flow, Velocity Flow, or Volume Flow. When bench commissioning, the flow values for each variable should be zero and the temperature value should be the ambient temperature.
If the units for the flow or temperature variables are not correct, refer to
Process variable units. Use the Process Variable Units function to select the
units for your application.
(HART)

6.1.2 Percent of range

ProLink III Device Tools Configuration Outputs Analog
The primary variable as a percentage of range provides a gauge as to where the measured flow rate 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 measured flow rate is 10 gal/min, the percent of range is 50 percent.

6.1.3 Analog output

ProLink III Device Tools Configuration Outputs Analog
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.

Process configuration

ProLink III Device Tools Configuration Device Setup
The flow meter can be used for liquid, gas, or steam applications, but it must be configured specifically for the application. If the flow meter is not configured for the proper process, readings will be inaccurate. Select the appropriate process configuration parameters for your application:
Set process fluid
Non­MultiVariable and MTA meters
Select the fluid type—either Liquid, Gas/Steam, Tcomp Sat Steam, or Tcomp Liquids. Tcomp Sat Steam and Tcomp Liquids require the MTA Option and provide dynamic density compensation based on the process temperature reading. For more information on temperature compensation configuration, please consult the advance functionality of the Operation section of the 00809-0100-4004 Manual.
MPA and MCA meters
Select the fluid type - either Liquid, Gas, or Steam. For more information on pressure and temperature compensation configuration, please consult the advanced installation and advanced configuration sections of the 00809-1100-4004 Manual.
Fixed process temperature
Needed for the electronics to compensate for thermal expansion of the flowmeter as the process temperature differs from the reference temperature. Process temperature is the temperature of the liquid or gas in the line during flowmeter operation.
May also be used as a back-up temperature value in the event of a temperature sensor failure if the MTA or MCA option is installed.
Fixed process density
A Fixed Process Density must be accurately configured if mass flow or corrected volume flow measurements are used. In mass flow it is used to convert volume flow to mass flow. In corrected volume flow it is used with the base process density to derive a density ratio which in turn is used to convert volume flow to corrected volume flow. In temperature compensated fluids the fixed process density is still required as it is used to convert volume flow sensor limits to sensor limits for temperature compensated fluids.
Note
If mass or corrected volume units are chosen, you must enter the density of your process fluid into the software. Be careful to enter the correct density. The mass flow rate and density ratio are calculated using this user-entered density, and unless:
Meters with MTA option
The transmitter is in TComp Sat Steam or TComp Liquids for MTA meters. When the process fluid is set to Tcomp Sat Steam or TComp Liquids, the changes in density are automatically being compensated for and any error in the user-entered density will cause error in the measurement.
44 Rosemount™ 8800D Series Vortex Flow Meter
Meters with MPA or MCA option
Base process density
The density of the fluid at base conditions. This density is used in corrected volume flow measurement. It is not required for volume flow, mass flow, or velocity flow. The Base Process Density is used with the Process Density to calculate the Density Ratio. In temperature compensated fluids, the Process Density is calculated by the transmitter. In non-temperature compensated fluids the Fixed Process Density is used to calculate a fixed Density Ratio. Density Ratio is used to convert actual volumetric flow to standard volumetric flow rates based on the following equation:
Density ratio = density at actual (flowing) conditions/density at standard (base) conditions
Actual Compensation reads Temperature, Pressure or Pressure and Temperature Compensation. If Actual Compensation reads Temperature, Pressure or Pressure and Temperature Compensation, density is automatically compensated, any error in the user-entered density will result in error in the measurement.

6.7 Pipe I.D.

ProLink III Device Tools Configuration Device Setup
The pipe I.D. (inside diameter) of the pipe adjacent to the flow meter can cause entrance effects that may alter flow meter readings. Configuring the actual mating pipe inside diameter will correct for theses effects. Enter the appropriate value for this variable.
Pipe I.D. values for schedule 10, 40, and 80 piping are given in the following table. If the mating pipe I.D. is not listed in the table, confirm it with the manufacturer or measure it yourself.

6.8 Upper and lower range values

ProLink III Device Tools Configuration Outputs Analog
Enables you to set the upper and lower range values in order to maximize the resolution of the analog output. The meter is most accurate when operated within the expected flow ranges for your application. Setting the range to the limits of expected readings will maximize flow meter performance.
The range of expected readings is defined by the Lower Range Value and Upper Range Value. Set the values within the limits of flow meter operation as defined by the line size and process material for your application. Values set outside that range will not be accepted.
Upper Range Value
Lower Range Value

6.9 Damping

ProLink III Device Tools Configuration Outputs Analog
Damping changes the response time of the flow meter to smooth variations in output readings caused by rapid changes in input. Damping is applied to the Analog Output, Primary Variable, Percent of Range, and Vortex Frequency.
The default damping value is 2.0 seconds. This can be configured to any value between 0.2 to 255 seconds when PV is a flow variable or 0.4 to 32 seconds when PV is Process Temperature. Determine the appropriate damping setting based on the necessary response time, signal stability, and other requirements of the loop dynamics in your system.
Output
This is the 20 mA set point for the meter.
This is the 4 mA set point for the meter, and is typically set to 0 when the primary variable is a flow variable.
Output
Note
If the vortex shedding frequency is slower than the damping value selected, no damping is applied. Process Temperature damping can be modified when PV is set to Process Temperature.

Optimize Digital Signal Processing (DSP)

ProLink III Device Tools Configuration Process
Measurement Signal Processing
A function that can be used to optimize the range of the flow meter based on the density of the fluid. The electronics uses process density to calculate the minimum measurable flow rate, while retaining at least a 4:1 signal to the trigger level ratio. This function will also reset all of the filters to optimize the flow meter performance over the new range. If the configuration of the device has changed, this method should be executed to ensure the signal processing parameters are set to their optimum settings. For dynamic process densities, select a density value that is lower than the lowest expected flowing density.
