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.

WARNING!

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.

Overview

A special measurement unit is a user-defined unit of measure that allows you to report
process data in a unit that is not available in the transmitter. A special measurement unit is
calculated from an existing measurement unit using a conversion factor. You can define a
special measurement unit for dynamic viscosity, kinematic viscosity, or both.

Procedure

• To define a special unit for dynamic viscosity:

1. Calculate Dynamic Viscosity Special Unit Conversion Factor as follows:

a. x base units = y special units

b. Dynamic Viscosity Special Unit Conversion Factor = x ÷ y

2. Enter Dynamic Viscosity Special Unit Conversion Factor.

3. Set User-Defined Label to the name you want to use for the dynamic viscosity unit.

• To define a special unit for kinematic viscosity:

1. Calculate Kinematic Viscosity Special Unit Conversion Factor as follows:

a. x base units = y special units

Configuration and Use Manual 19

Configure process measurement

b. Kinematic Viscosity Special Unit Conversion Factor = x ÷ y

2. Enter Kinematic Viscosity Special Unit Conversion Factor.

3. Set User-Defined Label to the name you want to use for the kinematic viscosity
unit.

The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.

Example: Defining a special measurement unit for kinematic viscosity

You want to measure kinematic viscosity in Stokes rather than centiStokes.

1. Calculate Kinematic Viscosity Special Unit Conversion Factor: 1 ÷ 100

4.2.2 Configure Viscosity Damping

Display Not available

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

Field Communicator Not available

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.

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.

20 Micro Motion® Fork Viscosity Meters (FVM)

Configure process measurement

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

Note

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

24 Micro Motion® Fork Viscosity Meters (FVM)

Configure process measurement

Procedure

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.

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.

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

Two-Phase Flow Timeout.

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

Configuration and Use Manual 25

Configure process measurement

• 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.

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.

Configuration and Use Manual 27

Configure process measurement

• 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.

4.4.3 Configure Temperature Input

Overview

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.

Tip

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

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 an external
temperature or the configured fixed value. Accordingly, if you set up polling for temperature in one
area, and digital communications in another, and configure a fixed temperature value in a third, the
fixed value will be overwritten by polling and digital communications, and polling and digital
communications will overwrite each other.

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.

56 Micro Motion® Fork Viscosity Meters (FVM)

Configure process measurement

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 an external
temperature or the configured fixed value. Accordingly, if you set up polling for temperature in one
area, and digital communications in another, and configure a fixed temperature value in a third, the
fixed value will be overwritten by polling and digital communications, and polling and digital
communications will overwrite each other.

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
external pressure will overwrite the fixed value.

Prerequisites

If you plan to poll an external device, the primary mA output must be wired to support
HART communications.

You must be using gauge pressure.

The pressure device must use the pressure unit that is configured in the transmitter.

If you are using an external temperature device, it must use the temperature unit that is

4.8 Set up concentration measurement

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

• Preparing to set up concentration measurement (Section 4.8.1)

• Set up concentration measurement using ProLink III (Section 4.8.2)

• Set up concentration measurement using the Field Communicator (Section 4.8.3)

4.8.1 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.

• 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

The concentration measurement application and the API referral application cannot
be enabled simultaneously.

3. Set Concentration Measurement to Enabled and click Apply.

Load a concentration matrix using ProLink III

At least one concentration matrix must be loaded onto your transmitter. You can load up
to six.

Tip

In many cases, concentration matrices were ordered with the device and loaded at the factory. You
may not need to load any matrices.

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.

Configuration and Use Manual 67

Configure process measurement

• 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

• If you want the meter to calculate Net Mass Flow Rate, the derived variable must be set to

• If you want the meter to calculate Net Volume Flow Rate, the derived variable must be set to

from transmitter memory. Set Derived Variable before loading concentration matrices.

Mass Concentration (Density). If your matrix is not set up for Mass Concentration (Density),
contact Micro Motion for assistance or for a custom matrix.

Volume Concentration (Density). If your matrix is not set up for Volume Concentration
(Density), contact Micro Motion for assistance or for a custom matrix.

If you plan to use matrix switching, you must identify the two matrices to be used for
switching and load them into Slot 1 and Slot 2.

Procedure

1. Choose Device Tools > Configuration > Process Measurement > Line Density and set Density
Unit to the density unit used by your matrix.

Important

When you load a matrix, if the density unit is not correct, concentration data will be incorrect.
The density units must match at the time of loading. You can change the density unit after
the matrix is loaded.

2. Choose Device Tools > Configuration > Process Measurement > Line Temperature and set
Temperature Unit to the temperature unit used by your matrix.

Important

When you load a matrix, if the temperature unit is not correct, concentration data will be
incorrect. The temperature units must match at the time of loading. You can change the
temperature unit after the matrix is loaded.

3. Choose Device Tools > Configuration > Process Measurement > Concentration Measurement.

The Concentration Measurement window is displayed. It is organized into steps that
allow you to perform several different setup and configuration tasks. For this task,
you will not use all the steps.

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.

Restriction

If Derived Variable is not set to Specific Gravity, do not change any of these values. These are set by the
active concentration matrix.

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,
the transmitter stores only one alternate temperature value, which may be either an external
temperature or the configured fixed value. Accordingly, if you set up polling for temperature in one
area, and digital communications in another, and configure a fixed temperature value in a third, the
fixed value will be overwritten by polling and digital communications, and polling and digital
communications will overwrite each other.

Prerequisites

If you plan to poll an external device, the primary mA output must be wired to support
HART communications.

Set reference temperature values for specific gravity using the Field Communicator

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.

Restriction

If Derived Variable is not set to Specific Gravity, do not change any of these values. These are set by the
active concentration matrix. To check the setting of Derived Variable, choose Configure > Manual Setup >
Measurements > Optional Setup > Concentration Measurement > CM Configuration.

Important

Do not change the setting of Derived Variable. If you change the setting of Derived Variable, all existing
concentration matrices will be deleted from transmitter memory.

Procedure

1. Choose Configure > Manual Setup > Measurements > Optional Setup > Concentration

Provide temperature data for concentration measurement using the Field Communicator

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,
the transmitter stores only one alternate temperature value, which may be either an external
temperature or the configured fixed value. Accordingly, if you set up polling for temperature in one
area, and digital communications in another, and configure a fixed temperature value in a third, the
fixed value will be overwritten by polling and digital communications, and polling and digital
communications will overwrite each other.

Prerequisites

If you plan to poll an external device, the primary mA output must be wired to support
HART communications.

4.8.5 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:

80 Micro Motion® Fork Viscosity Meters (FVM)

Configure process measurement

• 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.

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.
