2 Quick start

Topics covered in this chapter:

• Power up the transmitter

• Check meter status

• Make a startup connection to the transmitter

2.1 Power up the transmitter

The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.

1. Ensure that all transmitter and sensor covers and seals are closed.

CAUTION!

To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.

Quick start

2. Turn on the electrical power at the power supply.

The transmitter will automatically perform diagnostic routines. During this period,
Alert 009 is active. The diagnostic routines should complete in approximately
30 seconds.

Postrequisites

Although the sensor is ready to receive process fluid shortly after power-up, the electronics
can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial
startup, or if power has been off long enough to allow components to reach ambient
temperature, allow the electronics to warm up for approximately 10 minutes before
relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.

2.2 Check meter status

Check the meter for any error conditions that require user action or that affect
measurement accuracy.

1. Wait approximately 10 seconds for the power-up sequence to complete.

Immediately after power-up, the transmitter runs through diagnostic routines and
checks for error conditions. During the power-up sequence, Alert A009 is active.
This alert should clear automatically when the power-up sequence is complete.

2. Check the status LED on the transmitter.

Integrate the meter with the network

4 Integrate the meter with the network

Topics covered in this chapter:

• Assign function block channels to transducer block channels

• Configure AI Linearization

• Configure process alert limits for the AI blocks

• Configure the timeout for Field Diagnostic alerts

4.1 Assign function block channels to transducer
block channels

Fieldbus host AI or AO function block > CHANNEL

AI or AO function block > XD_SCALE (OD Index 10)

AI or AO function block > OUT_SCALE (OD Index 11)

Overview

Each of the four AI function blocks and the AO function block can be assigned to a
transducer block channel. Each transducer block channel is used for a single process
variable. The AI function blocks are used for input data (data sent from the transmitter to
the host). The AO function block is used for output data (data sent from the host to the
transmitter).

Channel assignment for the function blocksFigure 4-1:

Note

Perform these steps for each AI function block channel (1–4) and the AO function block channel, as
needed.

Configuration and Use Manual 13

Integrate the meter with the network

Procedure

1. Set the (AI or AO) function block channel to the transducer block channel this block

should report.

2. Make sure the transducer scale is set to the correct units, and change it if necessary.

3. Make sure the output scale units matches the transducer scale units, and change it if

necessary.

4.2 Configure AI Linearization

Fieldbus host AI function block > L_TYPE (OD Index 16)

Overview

AI Linearization is used to rescale a process variable. It can also be used to change the
measurement units. The default setting (Direct) is appropriate for most applications.

Procedure

1. Set AI Linearization as desired.

Option Description

Direct The AI block reports process variables directly from the Measurement trans-

ducer block.

Indirect The value from the Measurement transducer block is rescaled as specified by

the Transducer Scale parameters and the Output Scale parameters. The AI
block reports the inverse of the result.

Indirect
Square Root

Important

AI linearization affects only the process variable reported by the AI block. It has no effect on
the Measurement block. Therefore:

• If you set AI Linearization to Indirect or Indirect Square Root, the process variable reported by the

AI block will be different from the process variable read directly from the Measurement
block. Both the display and ProLink III read data directly from the Measurement block.

• Measurement parameters such as Density Damping and Density Cutoff are processed by the

Measurement block, and the result is passed through AI linearization. Using Ai
linearization to implement damping or cutoff processing may not be possible, and is not
recommended.

The value from the Measurement transducer block is rescaled as specified by
the Transducer Scale parameters and the Output Scale parameters. The AI
block reports the square root of the result. This setting is not applicable to
most Micro Motion meters.

2. If you selected Indirect or Indirect Square Root, set the Transducer Scale and Output
Scale parameters:

14 Micro Motion® Fork Viscosity Meters (FVM) with Foundation™ Fieldbus

Integrate the meter with the network

a. Set Transducer Scale: EU at 0% to the value of the process variable when the

transducer block reports 0%.

b. Set Transducer Scale: EU at 100% to the value of the process variable when the

transducer block reports 100%.

c. Set Output Scale: EU at 0% to the value of the process variable when the AI block

reports 0%.

d. Set Output Scale: EU at 100% to the value of the process variable when the AI block

reports 100%.

Specify the two transducer scale parameters in the measurement unit configured
for the transducer block. Specify the two output scale parameters in the
measurement unit configured for the AI block. In most cases, the transducer block
and the AI block use the same measurement unit.

Example: Using scaling to change the measurement unit

The transducer block is configured to measure density in g/cm³. You want the AI block to
report density in oz/in³.

Your lowest expected density value is 0.5 g/cm³. This is equivalent to 0.289 oz/in³.

Your highest expected density value is 0.85 g/cm³. This is equivalent to 0.491 oz/in³.

Set parameters as follows:

• AI Linearization = Indirect

• Transducer Scale: EU at 0% = 0.5

• Transducer Scale: EU at 100% = 0.85

• Output Scale: EU at 0% = 0.289

• Output Scale: EU at 100% = 0.491

Result: As line density varies between 0.5 g/cm³ and 0.85 g/cm³:

• The transducer block varies between 0% and 100%.

• The Measurement block converts this value to a value between 0.5 g/cm³ and

0.85 g/cm³. The result is reported on the display and set to the AI block.

• The AI block applies AI linearization, and reports a value between 0.289 oz/in³ and

0.85 oz/in³.

Integrate the meter with the network

4.3 Configure process alert limits for the AI blocks

Fieldbus host AI function block > HI_HI_LIM (OD Index 26)

AI function block > HI_HI_PRI (OD Index 25)

AI function block > HI_LIM (OD Index 28)

AI function block > HI_PRI (OD Index 27)

AI function block > LO_LIM (OD Index 30)

AI function block > LO_PRI (OD Index 29)

AI function block > LO_LO_LIM (OD Index 32)

AI function block > LO_LO_PRI (OD Index 31)

AI function block > ALARM_HYS (OD Index 24)

Overview

Process alerts are used to indicate that a process variable is outside the specified limits.
Each AI block has four alert limits: High-High, High, Low, and Low-Low. In general, the
range between High and Low represents the normal process range.

Process alerts are reported only by the affected AI block. They are not shown on the display
or reported by ProLink III.

Prerequisites

Before setting process alert limits, ensure that the four AI blocks are configured for the
appropriate transducer channel (process variable) and measurement unit.

Procedure

1. Select AI Block 1.

2. Set process alert limits:

a. Set the High-High alert to the value of the process variable that will cause the

transmitter to post a High-High alert for this AI block.

b. Set the High alert to the value of the process variable that will cause the

transmitter to post a High alert for this AI block.

c. Set the Low alert to the value of the process variable that will cause the

transmitter to post a Low alert for this AI block.

d. Set the Low-Low alert to the value of the process variable that will cause the

transmitter to post a Low-Low alert for this AI block.

3. For each process alert limit, set the alert priority.

The alert priority is a value between 0 and 15. Higher numbers represent higher
priorities. These values are used for fieldbus network management. They do not
affect transmitter operation: The transmitter will post the alert as soon as the
condition is detected.

4. Repeat for all other AI blocks.

5. Set the alert hysteresis.

16 Micro Motion® Fork Viscosity Meters (FVM) with Foundation™ Fieldbus

Integrate the meter with the network

The alert hysteresis defines a range around the alert limit that operates as a
deadband. The range is defined in terms of % of the output scale. Alert hysteresis is
used to suppress repetitive alerts when the process variable is hovering around the
alert limit.

• A higher value suppresses alerts across a wider range.

• A lower value suppresses alerts across a narrower range. Therefore, alerts may be

posted more frequently.

Important

The alert hysteresis applies to all AI blocks and to all process alert limits.

Example:

AI Block 1 is configured to report line density. The High alert is set at 1.0 g/cm³. The
alert hysteresis is set at 5%.

If line density goes above 1.05 g/cm³, the transmitter posts a High alert. The High
alert remains active until density goes below 0.95 g/cm³.

4.4 Configure the timeout for Field Diagnostic alerts

Fieldbus host DiagnosticsTB > Alert Index (OD Index 017)

Diagnostic TB > Alert timeout (OD Index 083)

Overview

Each Field Diagnostic alert has an individual Timeout parameter. If the alert occurs, it is not
sent to the host until the timeout has expired. Additionally, any associated AI blocks do not
go into fault until the timeout has expired. In other words, the process quality for the AI
block is reported as Good until the timeout expires.

Procedure

1. Set the alert index to the alert you want to configure.

2. Set the timeout as desired:

• Default: 0 seconds

• Range: 0 to 300 seconds

Overview

The calibration factors are used to adjust measurement for the unique traits of the sensor.
Your device was calibrated at the factory. However, you should verify that the calibration
factors that are configured in your device match the factory values.

Prerequisites

You will need the factory values for the calibration factors. These are provided in two
locations:

• The calibration certificate shipped with your meter

• The label inside the transmitter's end-cap

Configuration and Use Manual 19

Configure process measurement

Important

If the transmitter is not the original component, do not use the values from the transmitter label.

Procedure

1. View the calibration factors that are stored in the device.

2. Compare them to the factory values.

• If the values match, no action is required.

• If the values do not match, contact Micro Motion customer service.

Sample calibration certificate

5.1.1 Calibration factors

The original calibration factors are obtained from factory calibration, and are unique to
each device. They are used to adjust measurements for the specific physical properties of
the device.

The calibration certificate contains several sets of factors:

Viscosity
calibration
coefficients

Density calibration
coefficients

Temperature
compensation
coefficients

Viscosity
compensation
coefficients

The calibration certificate also provides the results of the Known Density Verification
procedure that was performed at the factory.

For each calibration performed at the factory, the calibration certificate contains the data
used to calculate the calibration coefficients.

Define the relationship between viscosity and the response of your
sensor. Viscosity calibration is performed for one to four viscosity
ranges, depending on the purchase order: Ultra-Low, Low,
Medium, and High. The meter continuously monitors the line
viscosity reading and automatically switches to the appropriate
set of calibration factors.

Define the relationship between density and the response of your
sensor.

Adjust density measurement for the effect of temperature on
sensor response.

Adjust density measurement for the effect of viscosity on sensor
response. There is a set of viscosity compensation coefficients for
the Medium viscosity range, and a set for the High viscosity range.
The viscosity compensation coefficients are generated only if the
corresponding viscosity range is calibrated on your device.

Display Not available

ProLink III Device Tools > Configuration > Process Measurement > Line Viscosity > Line Viscosity Damping

Overview

Viscosity Damping controls the amount of damping that will be applied to the line viscosity
value. It affects both dynamic viscosity and kinematic viscosity measurement.

Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes
in the process variable. At the end of the interval, the internal value will reflect 63% of the
change in the actual measured value.

Tip

Viscosity damping affects all process variables that are calculated from line viscosity.

22 Micro Motion® Fork Viscosity Meters (FVM) with Foundation™ Fieldbus

Configure process measurement

Procedure

Set Viscosity Damping to the value you want to use.

The default value is 0 seconds. The range is 0 to 440 seconds.

Interaction between Viscosity Damping and Added Damping

When the mA output is configured to report either dynamic viscosity or kinematic
viscosity, both Viscosity Damping and Added Damping are applied to the reported viscosity
value.

Viscosity Damping controls the rate of change in the value of the process variable in
transmitter memory. Added Damping controls the rate of change reported via the mA
output.

If mA Output Process Variable is set to Dynamic Viscosity or Kinematic Viscosity, and both Viscosity
Damping and Added Damping are set to non-zero values, viscosity damping is applied first,
and the added damping calculation is applied to the result of the first calculation. This
value is reported over the mA output.

Overview

The two-phase flow parameters control how the transmitter detects and reports two­phase flow (gas in a liquid process or liquid in a gas process).

Note

Two-phase flow is sometimes referred to as slug flow.

Procedure

Configure process measurement

1. Set Two-Phase Flow Low Limit to the lowest density value that is considered normal in
your process.

Values below this will cause the transmitter to post Alert A105 ().

Tip

Gas entrainment can cause your process density to drop temporarily. To reduce the
occurrence of two-phase flow alerts that are not significant to your process, set Two-Phase Flow
Low Limit slightly below your expected lowest process density.

You must enter Two-Phase Flow Low Limit in g/cm³, even if you configured another unit
for density measurement.

2. Set Two-Phase Flow High Limit to the highest density value that is considered normal in
your process.

Values above this will cause the transmitter to post Alert A105 (Two-Phase Flow).

Tip

To reduce the occurrence of two-phase flow alerts that are not significant to your process, set
Two-Phase Flow High Limit slightly above your expected highest process density.

You must enter Two-Phase Flow High Limit in g/cm³, even if you configured another
unit for density measurement.

3. Set Two-Phase Flow Timeout to the number of seconds that the transmitter will wait for
a two-phase flow condition to clear before posting the alert.

Configuration and Use Manual 27

Configure process measurement

Detecting and reporting two-phase flow

Two-phase flow (gas in a liquid process or liquid in a gas process) can cause a variety of
process control issues. By configuring the two-phase flow parameters appropriately for
your application, you can detect process conditions that require correction.

Tip

To decrease the occurrence of two-phase flow alerts, lower Two-Phase Flow Low Limit or raise Two-Phase
Flow High Limit.

A two-phase flow condition occurs whenever the measured density goes below Two-Phase
Flow Low Limit or above Two-Phase Flow High Limit. If this occurs:

• A two-phase flow alert is posted to the active alert log.

• Line density is held at its last pre‐alert value for the number of seconds configured in

The default value for Two-Phase Flow Timeout is 0.0 seconds, meaning that the alert
will be posted immediately. The range is 0.0 to 60.0 seconds.

Two-Phase Flow Timeout.

If the two-phase flow condition clears before Two-Phase Flow Timeout expires:

• Line density reverts to actual process density.

• The two-phase flow alert is deactivated, but remains in the active alert log until it is

acknowledged.

If the two-phase flow condition does not clear before Two-Phase Flow Timeout expires, line
density reverts to actual process density, but the two-phase flow alert remains active.

If Two-Phase Flow Timeout is set to 0.0 seconds, two-phase flow will cause a two-phase flow
alert but will have no effect on how the meter measures or reports line density.

Overview

Temperature Damping controls the amount of damping that will be applied to the line
temperature value, when the on-board temperature data is used (RTD).

Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes
in the process variable. At the end of the interval, the internal value will reflect 63% of the
change in the actual measured value.

Configuration and Use Manual 29

Configure process measurement

Tip

Temperature Damping affects all process variables, compensations, and corrections that use
temperature data from the sensor.

Procedure

Enter the value you want to use for Temperature Damping.

The default value is 4.8 seconds.

Tips

• A high damping value makes the process variable appear smoother because the reported value

changes slowly.

• A low damping value makes the process variable appear more erratic because the reported value

changes more quickly.

• Whenever the damping value is non-zero, the reported measurement will lag the actual

measurement because the reported value is being averaged over time.

• In general, lower damping values are preferable because there is less chance of data loss, and less

lag time between the actual measurement and the reported value.

The value you enter is automatically rounded down to the nearest valid value.

to.

Tip

Use an external device only if it is more accurate than the internal RTD.

30 Micro Motion® Fork Viscosity Meters (FVM) with Foundation™ Fieldbus

Configure process measurement

Important

Line temperature data is used in several different measurements and calculations. It is possible to
use the internal RTD temperature in some areas and an external temperature in others. The
transmitter stores the internal RTD temperature and the external temperature separately. However,
the transmitter stores only one alternate temperature value, which may be either the external
temperature or the configured fixed value. Accordingly, if you choose a fixed temperature for some
uses, and an external temperature for others, the external temperature will overwrite the fixed value.

Prerequisites

You must enable external temperature compensation before you can set the fixed
temperature value.

Procedure

• To use an external temperature value:

Referred viscosity is line viscosity corrected to a reference temperature. In other words, this
is the viscosity that the device would report if the line temperature matched the reference
temperature. The ASTM D341 multi-curve method is used only with petroleum products.
It is used when the meter will measure two to eight process fluids.

You can set up referred viscosity calculations for up to eight process fluids.

Important

Use the ASTM D341 Multi-Curve method only with petroleum products.

Prerequisites

For each process fluid, you must know its viscosity at two temperatures.

Procedure

Overview

Referred viscosity is line viscosity corrected to a reference temperature. In other words, this
is the viscosity that the device would report if the line temperature matched the reference
temperature. The matrix referral method can be used for all process fluids. It is not based
on ASTM D341 standards.

You can set up referred viscosity calculations for up to six process fluids. You must set up at
least two.

Prerequisites

For each process fluid, you must know its viscosity at two or more temperatures. You must
use the same temperature values for all process fluids. You can enter up to six
temperature–viscosity pairs for each fluid.

Procedure

1. Choose Device Tools > Configuration > Process Measurement > Referred Viscosity.

2. Set Referred Viscosity Method to Matrix Referral, and click Apply to refresh the screen.

3. Set Matrix Data Unit to the viscosity unit that the referred density measurement will be

based on, then click Apply to refresh the screen.

Important

If you change the setting of Matrix Data Unit after entering viscosity data in the matrix, no
conversion is performed. You must re-enter the viscosity data using the new unit.

4. Set Reference Temperature to the temperature to which viscosity will be corrected.

The reference temperature must be within the temperature range of the matrix. It
does not need to match one of the temperature values used to build the matrix.

5. Build the viscosity matrix.

6. Click Apply.

a. In the first column, enter the temperatures for which you will enter viscosity

data.

b. In the second column, enter the viscosity of the first process fluid, at each of the

specified temperatures.

Enter viscosity in either cP or cSt, depending on the setting of Matrix Data Unit.

c. In the third column, enter the viscosity of the second process fluid at each of the

specified temperatures.

d. Continue until you have entered and sent data for all process fluids at all

temperatures.

Important

• You must enter the temperature values in order, either low-to-high or high-to-low.

• You must enter the process fluids in order of viscosity, either low-to-high or high-to-low.

• The matrix must be 2×2 or larger.

The transmitter processes the matrix data and determines if it can be used for
measurement.

7. Check the values displayed for Fit Results and Fit Accuracy.

Fit Results can be Good, Poor, or Empty. Good means that the matrix is mathematically
capable of generating data. Poor means that the matrix cannot generate data. If Fit
Results = Poor, adjust the matrix and try again. If Fit Results = Empty, ensure that you
have entered data for all temperature–viscosity pairs and that the data meets the
requirements listed above.

Fit Accuracy is the maximum difference between the referred viscosity value
calculated by the meter and the referred viscosity value that is expected at each of
the temperature–viscosity pairs.

Set up temperature and pressure data for API referral using ProLink III

The API referral application uses temperature and pressure data in its calculations. You
must decide how to provide this data, then perform the required configuration and setup.

Tip

Fixed values for temperature or pressure are not recommended. Using a fixed temperature or
pressure value may produce inaccurate process data.

Important

Line temperature data is used in several different measurements and calculations. It is possible to
use the internal RTD temperature in some areas and an external temperature in others. The
transmitter stores the internal RTD temperature and the external temperature separately. However,
the transmitter stores only one alternate temperature value, which may be either the external
temperature or the configured fixed value. Accordingly, if you choose a fixed temperature for some
uses, and an external temperature for others, the external temperature will overwrite the fixed value.

Important

Line pressure data is used in several different measurements and calculations. The transmitter stores
only one pressure value, which may be either the external pressure or the configured fixed value.
Accordingly, if you choose a fixed pressure for some uses, and an external pressure for others, the

5.8 Set up concentration measurement

The concentration measurement application calculates concentration from line density
and line temperature.

• Preparing to set up concentration measurement (Section 5.8.1)

• Set up concentration measurement using ProLink III (Section 5.8.2)

5.8.1 Preparing to set up concentration measurement

The procedure for setting up concentration measurement application depends on how
your device was ordered and how you want to use the application. Review this information
before you begin.

Requirements for concentration measurement

To use the concentration measurement application, the following conditions must be met:

• The concentration measurement application must be enabled.

• One or more concentration matrices must be stored in your transmitter.

Tip

In most cases, the concentration matrix that you ordered was loaded at the factory. If you
need to add concentration matrices and you are using ProLink III, you can load concentration
matrices from a file or you can build a custom matrix. If you are using the
Field Communicator, you can build a custom matrix but you cannot load a matrix from a file.
This manual does not discuss building a custom matrix. For information on building a custom
matrix, see Micro Motion Enhanced Density Application: Theory, Configuration, and Use.

• If your concentration matrices use Specific Gravity as the derived variable, the

reference temperature values must be set.

• Temperature Source must be configured and set up.

Configuration and Use Manual 51

Configure process measurement

• One matrix must be selected as the active matrix (the matrix used for

measurement).

Optional tasks in setting up concentration measurement

The following tasks are optional:

• Modifying names and labels

• Configuring operational parameters

- Extrapolation alerts

- Calculation method (matrix or equation)

- Matrix switching

Prerequisites

Standard matrices for the concentration measurement application
Concentration measurement matrices available by order

The concentration measurement application must be enabled on your device.

For each concentration matrix that you want to load, you need a file containing the matrix
data. The ProLink III installation includes a set of standard concentration matrices. Other
matrices are available from Micro Motion.

Tips

• If you have a custom matrix on another device, you can save it to a file, then load it to the

current device.

• If you have a matrix file in ProLink II format, you can load it using ProLink III.

You must know the following information for your matrix:

• The derived variable that the matrix is designed to calculate

• The density unit that the matrix was built with

• The temperature unit that the matrix was built with

Important

• All concentration matrices on your transmitter must use the same derived variable.

• If you change the setting of Derived Variable, all existing concentration matrices will be deleted

Set reference temperature values for specific gravity using ProLink III

When Derived Variable is set to Specific Gravity, you must set the reference temperature to be
used for density measurement and the reference temperature of water, and then verify
the density of water at the configured reference temperature. The two reference
temperature values affect specific gravity measurement.

Additionally, the two reference temperature values affect any concentration process
variable that is calculated by equation, rather than by matrix, because the equations are
based on specific gravity.

Typically, the two reference temperature values are the same, but this is not required.

Set up temperature data for concentration measurement using ProLink III

The concentration measurement application uses line temperature data in its calculations.
You must decide how to provide this data, then perform the required configuration and
setup. Temperature data from the on-board temperature sensor (RTD) is always available.
You can set up an external temperature device and use external temperature data if you
want to.

The temperature setup that you establish here will be used for all concentration
measurement matrices on this meter.

Important

Line temperature data is used in several different measurements and calculations. It is possible to
use the internal RTD temperature in some areas and an external temperature in others. The
transmitter stores the internal RTD temperature and the external temperature separately. However,

5.8.3 Using equations to calculate specific gravity, °Baumé, °Brix, °Plato, and °Twaddell

Whenever the derived variable is set to Specific Gravity, you have the option of using
equations to calculate °Baumé, °Brix,°Plato, and °Twaddell, instead of matrix referral.
Whenever the equation method is used, the active matrix is used to measure referred
density. This value is used to calculate specific gravity. The result of the specific gravity
calculation is then used in the equations used to calculate °Baumé, °Brix, °Plato, or
°Twaddell.

Specific gravity is always calculated using the two reference temperatures that are
specified during concentration measurement configuration.

If you are measuring in °Baumé, the meter will automatically select the appropriate
equation according to the specific gravity of the process fluid, and will switch equations
when specific gravity crosses 1.0.

5.8.4 Matrix switching

Matrix switching can be used to measure different process fluids without resetting the
active matrix manually. Matrix switching can also be used to increase measurement
accuracy.

When matrix switching is enabled, the meter automatically switches between the matrices
in Slot 1 and Slot 2 whenever an extrapolation alert is present for the active matrix but
would not be generated by the other matrix. For example:

• The matrix in Slot 2 is active, the high-density extrapolation alert is enabled, and

matrix switching is enabled. Line density goes above the range of the matrix plus the
extrapolation limit. The meter posts an alert, then checks the range of the matrix in
Slot 1. No extrapolation alert would be posted, so the meter automatically switches
to the matrix in Slot 1.

• The matrix in Slot 2 is active, the high-density extrapolation alert is enabled, and

matrix switching is enabled. Line density goes above the range of the matrix plus the
extrapolation limit. The meter posts an alert, then checks the range of the matrix in
Slot 1. The current line density would also generate an extrapolation alert for this
matrix, so the meter does not switch.

You can control the conditions that trigger matrix switching by enabling or disabling
specific extrapolation alerts. For example, if the low-density and high-density extrapolation
alerts are enabled, but the low-temperature and high-temperature extrapolation alerts are
disabled, matrix switching will be triggered only by changes in line density. Changes in line
temperature will not trigger matrix switching.

Depending on your application, you may need to set up your matrices and extrapolation
limits so that there is no overlap in density and/or temperature, or so that there is slight
overlap.

Example: Using matrix switching to measure different process fluids

The line may contain either of two process fluids, depending on the current product. The
matrix in Slot 1 is appropriate for the first process fluid. The matrix in Slot 2 is appropriate
for the second process fluid. Whenever the line is switched, an extrapolation alert is posted
for the current matrix, and the meter automatically switches to use the other matrix.

To ensure that the correct matrix is used, there can be no overlap between the ranges of
the two matrices. In other words:

• If you are using density to trigger matrix switching, there can be no density values

that are within the ranges of both matrices, after the extrapolation limits are
applied.

• If you are using temperature to trigger matrix switching, there can be no

temperature values that are within the ranges of both matrices, after the
extrapolation limits are applied.

• If you are using both density and temperature to trigger matrix switching, there can

be no density or temperature values that are within the ranges of both matrices,
after the extrapolation limits are applied.

60 Micro Motion® Fork Viscosity Meters (FVM) with Foundation™ Fieldbus

Configure process measurement

Example: Using matrix switching to increase measurement accuracy

For some process fluids, measurement accuracy is increased when the matrix has a
narrower temperature or density range. By using two matrices with adjacent or slightly
overlapping ranges, increased accuracy is available over a wider range of process variation.

To ensure continuous process measurement, there should be no gap between the ranges,
after the extrapolation limits are applied.

8.2 View process variables

Process variables provide information about the state of the process fluid, such as flow
rate, density, and temperature, as well as running totals. Process variables can also provide
data about flowmeter operation, such as drive gain and pickoff voltage. This information
can be used to understand and troubleshoot your process.

Overview

You can adjust viscosity measurement by applying an offset.

Tip

You can adjust line viscosity measurement with Viscosity Meter Factor, Viscosity Offset, or both. Viscosity
Meter Factor is applied to the measured dynamic viscosity, and Viscosity Offset is added to the result.

Kinematic viscosity is calculated from this value. Referred viscosity may be calculated from either
dynamic viscosity or kinematic viscosity, depending on the configuration.

The default value of Viscosity Offset is 0. Accordingly, the default value has no effect on
viscosity measurement.

Procedure

Enter the desired viscosity offset, in cP.

The default value is 0. The range is unlimited.

9.3 Adjust viscosity measurement with Viscosity
Meter Factor

You can adjust viscosity measurement by applying a viscosity meter factor. The measured
dynamic viscosity is always multiplied by the viscosity meter factor. The result is used in
further calculations.
