10 Micro Motion 4200 Transmitters
Configuration and Use Manual Quick start
MMI-20048166 April 2019
2 Quick start
2.1 Applying power
The transmitter must be powered up for all configuration and commissioning tasks, or for process
measurement.
Procedure
1. Verify that the cables are connected to the transmitter as described in the installation manual.
2. Verify 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.
3. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period, the Transmitter
Initializing alert 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.
When the flowmeter has completed its power-up sequence, if the default settings are in effect:
• The display will show the current mass flow rate and measurement unit.
• If there are any active fault or informational alarms, the alert banner displays until the alert has been
manually acknowledged.
• If the alert has been acknowledged but is still active, the alert icon displays above the menu button, and
the Alert List menu appears at the top of the main menu.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect measurement accuracy.
Procedure
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, the Transmitter Initializing alert is active. This alert
should clear automatically when the power-up sequence is complete.

Quick start Configuration and Use Manual
April 2019 MMI-20048166
The base model code completely describes your transmitter, except for the features that can be
licensed independently. The base model code is set at the factory.
e) Set Model Code (Options) to the options model code of the transmitter.
The options model code describes the independent features that have been licensed for this
transmitter. The original options model code is set at the factory. If you license additional
options for this transmitter, Micro Motion will supply an updated options model code.
2. Set informational parameters for the sensor.
a) Set Sensor Serial Number to the serial number of the sensor connected to this transmitter.
The sensor serial number is provided on the metal tag that is attached to the sensor case.
b) Set Sensor Material to the material used for the sensor.
c) Set Sensor Liner to the material used for the sensor liner.
d) Set Flange Type to the type of flange that was used to install the sensor.
Do not set Sensor Type. Sensor Type is set or derived during characterization.
2.8 Characterize the meter (if required)
Display
ProLink III Device Tools > Calibration Data
Field Communicator Configure > Manual Setup > Characterization
Characterizing the meter adjusts your transmitter to match the unique traits of the sensor it is paired with.
The characterization parameters (also called calibration parameters) describe the sensor’s sensitivity to flow,
density, and temperature. Depending on your sensor type, different parameters are required.
Values for your sensor are provided on the sensor tag or the calibration certificate.
• If your transmitter was ordered with a sensor, it was characterized at the factory. However, you should still
verify the characterization parameters.
• Perform a characterization whenever you replace a core processor.
Procedure
1. Optional: Specify Sensor Type as Curved Tube.
Note
Unlike earlier transmitters, the 4200 derives Sensor Type from the user-specified values for FCF and K1
in combination with an internal ID.
2. Set the flow calibration factor: FCF (also called Flow Cal or Flow Calibration Factor). Be sure to include
all decimal points.
3. Set the density characterization parameters: D1, D2, TC, K1, K2, and FD. (TC is sometimes shown as
DT.)
4. Apply the changes as required by the tool you are using.
Menu > Configuration > Sensor Parameters
14 Micro Motion 4200 Transmitters
Configuration and Use Manual Quick start
MMI-20048166 April 2019
The transmitter identifies your sensor type, and characterization parameters are adjusted as required:
• If Sensor Type changed from Straight Tube to Curved Tube, five characterization parameters are
removed from the list.
• If Sensor Type did not change, the list of characterization parameters does not change.

Configuration and Use Manual 15
Quick start Configuration and Use Manual
April 2019 MMI-20048166
2.8.2 Flow calibration parameters (FCF, FT)
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4-character FT value.
They are provided on the sensor tag.
Both values contain decimal points. During characterization, these are entered as a single 10-character string.
The 10-character string is called either Flowcal or FCF.
If your sensor tag shows the FCF and the FT values separately and you need to enter a single value,
concatenate the two values to form the single parameter value, retaining both decimal points.
Concatenating FCF and FT
FCF = x.xxxx FT = y.yy Flow calibration parameter: x.xxxxy.yy
2.8.3 Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)
Density calibration parameters are typically on the sensor tag and the calibration certificate.
If your sensor tag does not show a D1 or D2 value:
• For D1, enter the Dens A or D1 value from the calibration certificate. This value is the line-condition
density of the low-density calibration fluid. Micro Motion uses air. If you cannot find a Dens A or D1 value,
enter 0.001 g/cm3.
• For D2, enter the Dens B or D2 value from the calibration certificate. This value is the line-condition density
of the high-density calibration fluid. Micro Motion uses water. If you cannot find a Dens B or D2 value,
enter 0.998g/cm3 .
If your sensor tag does not show a K1 or K2 value:
• For K1, enter the first 5 digits of the density calibration factor. In this sample tag, this value is shown as
12500.
• For K2, enter the second 5 digits of the density calibration factor. In this sample tag, this value is shown as
14286.

MMI-20048166 April 2019
If your sensor does not show an FD value, contact customer service.
If your sensor tag does not show a DT or TC value, enter the last 4 characters of the density calibration factor.
In the sample tag shown above, the value is shown as 4.44.
2.9 Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use any available
method.
Procedure
• Read the value for Mass Flow Rate on the transmitter display, which is the default initial display.
• Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in the Process Variables
panel.
• Connect to the transmitter with the Field Communicator and read the value for Mass Flow Rate.
Online > Overview > Mass Flow Rate
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.
• Review the troubleshooting suggestions for flow measurement issues.
2.10 Verify the zero
Display
ProLink III Device Tools > Calibration > Smart Zero Verification and Calibration > Verify Zero
Field Communicator Service Tools > Maintenance > Calibration > Zero Calibration > Perform Zero Verify
Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field
zero can improve measurement accuracy.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the meter unless one of the
following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Prerequisites
Important
Do not verify the zero or zero the meter if a high-severity alert is active. Correct the problem, then verify the
zero or zero the meter. You may verify the zero or zero the meter if a low-severity alert is active.

Sensor Flow Direction Arrow interacts with mA Output Direction, Frequency Output Direction, and
Totalizer Direction to control how flow is reported by the outputs and accumulated by the totalizers and
inventories.
Sensor Flow Direction Arrow also affects how flow is reported on the transmitter display and via digital
communications. This includes ProLink III and the Field Communicator.

A special measurement unit is a user-defined unit of measure that allows you to report process data, totalizer
data, and inventory 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.
Procedure
1. Specify Base Mass Unit.
Base Mass Unit is the existing mass unit that the special unit will be based on.
2. Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
3. Calculate Mass Flow Conversion Factor as follows:
a) x base units = y special units
b) Mass Flow Conversion Factor = x ÷ y
4. Enter Mass Flow Conversion Factor.
The original mass flow rate value is divided by this value.
5. Set Mass Flow Label to the name you want to use for the mass flow unit.
6. Set Mass Total Label to the name you want to use for the mass total and mass inventory unit.
The special measurement unit is stored in the transmitter. You can configure the transmitter to use the
special measurement unit at any time.
Defining a special measurement unit for mass flow
You want to measure mass flow in ounces per second (oz/sec).
1. Set Base Mass Unit to Pounds (lb).
2. Set Base Time Unit to Seconds (sec).
3. Calculate Mass Flow Conversion Factor:
a. 1 lb/sec = 16 oz/sec
b. Mass Flow Conversion Factor = 1 ÷ 16 = 0.0625

April 2019 MMI-20048166
Flow Damping controls the amount of damping that will be applied to the measured mass flow rate. It affects
flow rate process variables that are based on the measured mass flow rate. This includes volume flow rate and
gas standard volume flow rate.
Flow Damping also affects specialized flow rate variables such as temperature-corrected volume flow rate
(API referral) and net mass flow rate (concentration measurement). It is not applied to the flow rate received
via the frequency input.
Damping is used to smooth out small, rapid fluctuations in process measurement. The 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 of the process variable (the damped value) will reflect 63% of the
change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
• Default: 0.64 seconds
• Range: 0 seconds to 60 seconds
Note
If a number greater than 60 is entered, it is automatically changed to 60.
Tip
• 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.
• The combination of a high damping value and rapid, large changes in flow rate can result in increased
measurement error.
• 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 transmitter automatically rounds off any entered damping value to the nearest valid value. Therefore,
the recommended damping value for gas applications should be 3.2 seconds. If you enter 2.56, the
transmitter will round it off to 3.2.
• For filling applications, Micro Motion recommends using the default value of 0.04 seconds.

Effect of flow damping on volume measurement
Flow damping affects volume measurement for liquid volume data. Flow damping also affects volume
measurement for gas standard volume data. The transmitter calculates volume data from the damped mass
flow data.
Interaction between Flow Damping and mA Output Damping
In some circumstances, both Flow Damping and mA Output Damping are applied to the reported mass flow
value.
Flow Damping controls the rate of change in flow process variables. mA Output Damping controls the rate
of change reported via the mA Output. If mA Output Process Variable is set to Mass Flow Rate, and both
Flow Damping and mA Output Damping are set to non-zero values, flow damping is applied first, and the
added damping calculation is applied to the result of the first calculation.
4.2.3 Configure Mass Flow Cutoff
Display Menu > Configuration > Process Measurement > Flow Variables > Mass Flow Settings > Low Flow Cutoff
ProLink III Device Tools > Configuration > Process Measurement > Flow > Mass Flow Cutoff
Field Communicator Configure > Manual Setup > Measurements > Flow > Mass Flow Cutoff
Mass Flow Cutoff specifies the lowest mass flow rate that will be reported as measured. All mass flow rates
below this cutoff will be reported as 0.
Procedure
Set Mass Flow Cutoff to the value you want to use.
• Default: A sensor-specific value set at the factory. If your transmitter was ordered without a sensor, the
default may be 0.0.
• Recommendation: 0.5% of maximum flow rate of the attached sensor. See the sensor specifications.
Important
Do not use your meter for measurement with Mass Flow Cutoff set to 0.0 g/sec. Ensure that Mass Flow
Cutoff is set to the value that is appropriate for your sensor.
Effect of Mass Flow Cutoff on volume measurement
Mass Flow Cutoff does not affect volume measurement. Volume data is calculated from the actual mass data
rather than the reported value.
Volume flow has a separate Volume Flow Cutoff that is not affected by the Mass Flow Cutoff value.
Interaction between Mass Flow Cutoff and mA Output Cutoff
Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as measured. mA
Output Cutoff defines the lowest flow rate that will be reported via the mA Output. If mA Output Process
Configuration and Use Manual 27

Variable is set to Mass Flow Rate, the mass flow rate reported via the mA Output is controlled by the higher of
the two cutoff values.
Mass Flow Cutoff affects all reported values and values used in other transmitter behavior (e.g., events
defined on mass flow).
mA Output Cutoff affects only mass flow values reported via the mA Output.

Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 10 g/sec
• Mass Flow Cutoff: 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, mass flow will be reported as 0, and 0 will be used in all
internal processing.

Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 15 g/sec

Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
— The mA Output will report zero flow.
— The Frequency Output will report the actual flow rate, and the actual flow rate will be used in all
internal processing.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0 will be used in all
internal processing.

4.5.2 Configure Density Damping
Display Menu > Configuration > Process Measurement > Density > Damping
ProLink III Device Tools > Configuration > Process Measurement > Density > Density Damping
Field Communicator Configure > Manual Setup > Measurements > Density > Density Damping
Density Damping controls the amount of damping that will be applied to density data.
Damping is used to smooth out small, rapid fluctuations in process measurement. The 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 of the process variable (the damped value) will reflect 63% of the
change in the actual measured value.
Procedure
Set Density Damping to the desired value.
• Default: 1.28 seconds
• Range: 0.0 to 60 seconds
Tip
• 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.
• The combination of a high damping value and rapid, large changes in density can result in increased
measurement error.
• Whenever the damping value is non-zero, the damped value will lag the actual measurement because the
damped 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 damped value.
• If a number greater than 60 is entered, it is automatically changed to 60.
Effect of Density Damping on volume measurement
Density Damping affects liquid volume measurement. Liquid volume values are calculated from the damped
density value rather than the measured density value. Density Damping does not affect gas standard volume
measurement.
Interaction between Density Damping and mA Output Damping
When the mA Output is configured to report density, both Density Damping and mA Output Damping are
applied to the reported density value.
Density Damping controls the rate of change in the value of the process variable in transmitter memory. mA
Output Damping controls the rate of change reported via the mA Output.
Configuration and Use Manual 37
Configure process measurement Configuration and Use Manual
April 2019 MMI-20048166
If mA Output Source is set to Density, and both Density Damping and mA Output Damping are set to nonzero values, density damping is applied first, and the mA Output damping calculation is applied to the result
of the first calculation. This value is reported over the mA Output.
4.5.3 Configure Density Cutoff
Display Menu > Configuration > Process Measurement > Density > Cutoff
ProLink III Device Tools > Configuration > Process Measurement > Density > Density Cutoff
Field Communicator Configure > Manual Setup > Measurements > Density > Density Cutoff
Density Cutoff specifies the lowest density value that will be reported as measured. All density values below
this cutoff will be reported as 0.
Procedure
Set Density Cutoff to the value you want to use.
• Default: 0.2 g/cm³
• Range: 0.0 g/cm³ to 0.5 g/cm³
Effect of Density Cutoff on volume measurement
Density Cutoff affects liquid volume measurement. If the density value goes below Density Cutoff, the
volume flow rate is reported as 0. Density Cutoff does not affect gas standard volume measurement. Gas
standard volume values are always calculated from the value configured for Standard Gas Density or polled
value if configured for polled base density.
4.6 Configure temperature measurement
The temperature measurement parameters control how temperature data is processed. Temperature data is
used in several different ways, including temperature compensation, API referral, and concentration
measurement.

Field Communicator Configure > Manual Setup > Measurements > Temperature > Damping
Temperature Damping controls the amount of damping that will be applied to temperature data from the
sensor. Temperature Damping is not applied to external temperature data.
Damping is used to smooth out small, rapid fluctuations in process measurement. The 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 of the process variable (the damped value) will reflect 63% of the
change in the actual measured value.
Procedure
Set Temperature Damping to the desired value.
• Default: 4.8 seconds
• Range: 0.0 to 80 seconds
Note
If a number greater than 80 is entered, it is automatically changed to 80.
Tip
• 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.
• The combination of a high damping value and rapid, large changes in temperature can result in increased
measurement error.
• Whenever the damping value is non-zero, the damped value will lag the actual measurement because the
damped 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 damped value.

Effect of Temperature Damping on process measurement
Temperature Damping affects all processes and algorithms that use temperature data from the internal
sensor RTD.
Temperature compensation
Temperature compensation adjusts process measurement to compensate for the effect of temperature on
the sensor tubes.
API referral
Temperature Damping affects API referral process variables only if the transmitter is configured to use
temperature data from the sensor. If an external temperature value is used for API referral, Temperature
Damping does not affect API referral process variables.
Concentration measurement
Temperature Damping affects concentration measurement process variables only if the transmitter is
configured to use temperature data from the sensor. If an external temperature value is used for
concentration measurement, Temperature Damping does not affect concentration measurement process
variables.

(1) Each API table represents a specialized equation defined by the American Petroleum Institute for a specific combination
of process fluid, line conditions, and output.
(2) Referred density is calculated from line density. You must specify this table, either directly or by selecting the process
fluid and base density measurement unit.
(3) You do not need to specify this table. It is invoked automatically as a result of the previous table selection.
(4) CTL or CTPL is calculated from the result of the referred density calculation. A, B, C, and D tables calculate CTPL, which
is a correction factor based on both line pressure and line temperature. E tables calculate CTL, which is a correction
factor based on line temperature and pressure at saturation conditions (bubble point or saturation vapor pressure).
(5) The Thermal Expansion Coefficient (TEC) replaces the referred density calculation. Use the CTL/CTPL table instead.

5.2 Set up concentration measurement
The concentration measurement application calculates concentration from line density and line temperature.
5.2.1 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.
• The API Referral application must be disabled.
• The advanced phase measurement application must be disabled.
• A concentration matrix must be loaded into one of the six slots on the transmitter.
Tip
In most cases, the concentration matrix that you ordered was loaded at the factory. If it was not, you have
several options for loading a matrix. You can also build a matrix.
56 Micro Motion 4200 Transmitters
Configuration and Use Manual Configure process measurement applications
MMI-20048166 April 2019
• Temperature Source must be configured and set up.
• One matrix must be selected as the active matrix (the matrix used for measurement).
Requirements for matrices
A matrix is the set of coefficients used to convert process data to concentration, plus related parameters. The
matrix can be saved as a file.
The transmitter requires all matrices to be in .matrix format. You can use ProLink III to load matrices in other
formats:
• .edf (used by ProLink II )
• .xml (used by ProLink III )
The transmitter can store matrices in one of the six slots in memory.
Any matrix in a slot is available for use. In other words, it can be selected as the active matrix and used for
measurement.
All matrices in slots must use the same derived variable.
See the following table for the different ways that you can load matrices.
Requirements for derived variables
A derived variable is the process variable that a concentration matrix measures. All other process variables are
calculated from the derived variable. There are eight possible derived variables. Each matrix is designed for
one specific derived variable.
The transmitter can store up to six matrices in six slots. All matrices in the six slots must use the same derived
variable. If you change the setting of Derived Variable, all matrices are deleted from the six slots.
Tip
Always ensure that Derived Variable is set correctly before loading matrices into slots.
Derived variables and net flow rate
If you want the transmitter to calculate Net Mass Flow Rate, the derived variable must be set to Mass
Concentration (Density). If your matrix is not designed for Mass Concentration (Density), contact
Micro Motion for assistance.
If you want the transmitter to calculate Net Volume Flow Rate, the derived variable must be set to Volume
Concentration (Density). If your matrix is not designed for Volume Concentration (Density), contact
Micro Motion for assistance.
Derived variables based on specific gravity
The following derived variables are based on specific gravity:
• Specific Gravity
• Concentration (Specific Gravity)
• Mass Concentration (Specific Gravity)
• Volume Concentration (Specific Gravity)
If you are using one of these derived variables, two additional parameters can be configured:
• Reference Temperature of Water (default setting: 4 °C)
Configuration and Use Manual 57
Configure process measurement applications Configuration and Use Manual
April 2019 MMI-20048166
• Water Density at Reference Temperature(default setting: 999.99988 kg/m³)
These two parameters are used to calculate specific gravity.
You cannot set these parameters from the display. If the default values are not appropriate, you must use
another method to set them.
Optional tasks in setting up concentration measurement
The following tasks are optional:
• Modifying names and labels
• Configuring extrapolation alerts
5.2.2 Set up concentration measurement using ProLink III
This section guides you through the tasks required to set up, configure, and implement concentration
measurement.
Enable the concentration measurement application using ProLink III
The concentration measurement application must be enabled before you can perform any setup. If the
concentration measurement application was enabled at the factory, you do not need to enable it now.
Prerequisites
• The concentration measurement application must be licensed on your transmitter.
• The concentration measurement application cannot be enabled at the same time as the API referral
application or the Advanced Phase Measurement application. They must be disabled first.
Procedure
1. Choose Device Tools > Configuration > Process Measurement > Flow and ensure that Volume Flow
Type is set to Liquid Volume.
2. Choose Device Tools > Configuration > Transmitter Options.
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.
Prerequisites
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. The file can be on your computer or in the transmitter's internal memory.
The file must be in one of the formats that ProLink III supports. This includes:
• .xml (ProLink III)
• .matrix (4200)
If you are loading an .xml file, you must know the following information for your matrix:
58 Micro Motion 4200 Transmitters
Configuration and Use Manual Configure process measurement applications
MMI-20048166 April 2019
• 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
If you are loading a .matrix file, you must know the derived variable that the matrix is designed to calculate.
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 from the
six slots on the transmitter, but not from the transmitter's SD card. Set Derived Variable before loading
concentration matrices.
Tip
In many cases, concentration matrices were ordered with the device and loaded at the factory. You may not
need to load any matrices.
Restriction
You cannot use ProLink III to load a matrix to the transmitter's SD card. ProLink III loads matrices directly to
one of the transmitter's six slots.
Procedure
1. If you are loading an .xml file, 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 in one of these formats, 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. If you are loading an .xml file, choose Device Tools > Configuration > Process Measurement > Line
Temperatureand set Temperature Unit to the temperature unit used by your matrix.
Important
When you load a matrix in one of these formats, 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.
4. In Step 1, ensure that the setting of Derived Variable matches the derived variable used by your
matrix. If it does not, change it as required and click Apply.
Important
If you change the setting of Derived Variable, all existing concentration matrices will be deleted from
the six slots. Verify the setting of Derived Variable before continuing.
5. Load one or more matrices.
a) In Step 2, set Matrix Being Configured to the location (slot) to which the matrix will be loaded.

for measurement.
Set reference temperature values for specific gravity using ProLink III
When Derived Variable is set to any option based on specific gravity, you must set the reference temperature
for water, then verify the density of water at the configured reference temperature. These values affect
specific gravity measurement.
This requirement applies to the following derived variables:
• Specific Gravity
• Concentration (Specific Gravity)
• Mass Concentration (Specific Gravity)
• Volume Concentration (Specific Gravity)
Procedure
1. 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.
2. Scroll to Step 2, set Matrix Being Configured to the matrix you want to modify, and click Change

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 onboard 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.
Procedure

6.1 Detect and report 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.
The transmitter provides two methods to detect and report or respond to two-phase flow.
6.1.1 Detect two-phase flow using density
Display Menu > Configuration > Process Measurement > Density
ProLink III Device Tools > Configuration > Process Measurement > Density
Field Communicator Configure > Manual Setup > Measurements > Density > Slug Low Limit
Configure > Manual Setup > Measurements > Density > Slug High Limit
Configure > Manual Setup > Measurements > Density > Slug Duration
The transmitter can use line density data to detect two-phase flow (gas in a liquid process or liquid in a gas
process). The density limits are user-specified. When two-phase flow is detected, an alert is posted.
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 a Process Aberration alert.
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the occurrence of twophase 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.
• Default: 0 g/cm³
• Range: 0 g/cm³ to the sensor limit
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 a Process Aberration alert.
Tip
To reduce the occurrence of two-phase flow alerts that are not significant to your process, set TwoPhase 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.
• Default: 5 g/cm³
• Range: 5 g/cm³ to the sensor limit

April 2019 MMI-20048166
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.
• Default: 0 seconds, meaning that the alert will be posted immediately
• Range: 0 to 60 seconds
6.1.2 Detect two-phase flow using sensor diagnostics
Display Menu > Configuration > Inputs/Outputs > Channel x > I/O Settings > Source
ProLink III Device Tools > Configuration > I/O > Outputs > mA Output x
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x > mA Output x > mAOxSource
The transmitter always monitors sensor diagnostics and applies a two-phase flow algorithm. You can assign
an mA Output to report the results of this calculation: single-phase flow, moderate two-phase flow, or severe
two-phase flow.
Procedure
Set mA Output Source to Two-Phase Flow Detection.
The signal from the mA output indicates the current state of the process:
• 12 mA: Single-phase flow
• 16 mA: Moderate two-phase flow
• 20 mA: Severe two-phase flow
6.2 Configure Flow Rate Switch
Display
ProLink III Device Tools > Configuration > I/O > Outputs > Discrete Output > Source > Flow Switch Indication
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x > Discrete Output x > Flow Switch
Flow Rate Switch is used to indicate that the flow rate has moved past a user-specified setpoint, in either
direction. The flow rate switch is implemented with a user-configurable hysteresis.
Typically, a Discrete Output is assigned as the flow rate switch indicator. The Discrete Output can be wired to
an external device such as a light or a horn.
Prerequisites
A channel must be configured as a Discrete Output, and the Discrete Output must be available for this use.
Menu > Configuration > Alert Setup > Enhanced Events > Flow Rate Switch
Procedure
1. Set Discrete Output Source to Flow Switch, if you have not already done so.
2. Set Flow Switch Variable to the flow variable that you want to use to control the flow rate switch.
3. Set Flow Switch Setpoint to the value at which the flow switch will be triggered (after Hysteresis is
applied).
• If the flow rate is below this value, the Discrete Output is ON.
70 Micro Motion 4200 Transmitters
Configuration and Use Manual Configure advanced options for process measurement
MMI-20048166 April 2019
• If the flow rate is above this value, the Discrete Output is OFF.
4. Set Hysteresis to the percentage of variation above and below the setpoint that will operate as a
deadband.
Hysteresis defines a range around the setpoint within which the flow rate switch will not change.
• Default: 5%
• Range: 0.1% to 10%
Example
If Flow Switch Setpoint = 100 g/sec and Hysteresis = 5%, and the first measured flow rate is above
100 g/sec, the discrete output is OFF. It will remain OFF unless the flow rate drops below 95 g/sec. If
this happens, the discrete output will turn ON, and remain ON until the flow rate rises above 105 g/sec.

6.3 Configure events
An event occurs when the real-time value of a user-specified process variable moves past a user-defined
setpoint. Events are used to provide notification of process changes or to perform specific transmitter actions
if a process change occurs.
Your transmitter supports the enhanced event model.
Tip
Enhanced events allow:
• Defining events by range (In Range or Out of Range), in addition to High and Low
• Triggering transmitter actions if an event occurs
6.3.1 Configure an enhanced event
Display
ProLink III Device Tools > Configuration > Events > Enhanced Events
Field Communicator Configure > Alert Setup > Enhanced Events
An enhanced event is used to provide notification of process changes and, optionally, to perform specific
transmitter actions if the event occurs. An enhanced event occurs (is ON) if the real-time value of a userspecified process variable moves above (HI) or below (LO) a user-defined setpoint, or in range (IN) or out of
range (OUT) with respect to two user-defined setpoints. Event status can be queried via digital
communications, and a discrete output can be configured to report event status.
Menu > Configuration > Alert Setup > Enhanced Events
You can define up to five enhanced events. For each enhanced event, you can assign one or more actions that
the transmitter will perform if the enhanced event occurs.

The transmitter provides seven configurable totalizers and seven configurable inventories. Each totalizer and
each inventory can be configured independently.
Totalizers track the process since the last totalizer reset. Inventories track the process since the last inventory
reset. Inventories are typically used to track the process across totalizer resets.
Tip
The default configurations cover the most typical uses of totalizers and inventories. You may not need to
change any configurations.
Prerequisites
Before configuring the totalizers and inventories, ensure that the process variables you plan to track are
available on the transmitter.
Procedure
1. Select the totalizer or inventory that you want to configure.
2. Set Totalizer Source or Inventory Source to the process variable that the totalizer or inventory will
track.
Option

Net volume flow The totalizer or inventory will track Net Volume Flow Rate and calculate
total volume since the last reset.
Note
The totalizer/inventory value will not automatically be reset when the source is changed. The user must
manually reset the totalizer/inventory.
Tip
If you are using the API referral application and you want to measure batch-weighted average density
or batch-weighted average temperature, you must have a totalizer configured to measure
temperature-corrected volume flow.
3. Set Totalizer Direction to specify how the totalizer or inventory will respond to forward or reverse flow.

4. Optional: Set User Name to the name you want to use for the inventory or totalizer.
User Name can have a maximum of 16 characters.
The transmitter automatically generates a name for each totalizer and inventory, based on its source,
direction, and type.
Example
• Totalizer Source=Mass Flow
• Totalizer Direction=Forward Only
• Totalizer name=Mass Fwd Total
Example
• Inventory Source=Gas Standard Volume Flow
• Inventory Direction=Bidirectional
• Inventory name=GSV Bidir Inv
The specified name is used on the transmitter display and on all interfaces that support it. If User Name
contains only spaces, the transmitter-generated name is used. Not all interfaces support totalizer and
inventory names.
Checking for backflow
You suspect that there is a significant amount of backflow through the sensor. To collect data, configure two
totalizers as follows:
• Source=Mass Flow, Direction=Forward Only
• Source=Mass Flow, Direction=Reverse Only
Reset both totalizers, allow them to run for an appropriate period, then look at the amount of reverse flow as
a percentage of forward flow.
Tracking three different process fluids
Three tanks are connected to a loading dock through a single meter. Each tank contains a different process
fluid. You want to track each process fluid separately.
1. Set up three totalizers, one for each tank.
2. Name the totalizers Tank 1, Tank 2, and Tank 3.
3. Configure each totalizer as required for the corresponding process fluid.
4. Stop and reset all three totalizers to ensure that the beginning values are 0.
5. When loading from a tank, start the corresponding totalizer, and stop it when the load is finished.

Process Variable Fault Action specifies the values that will be reported via the display and digital
communications if the device encounters a fault condition. The values are also sent to the outputs for
processing against their configured fault actions.
Procedure
Set Process Variable Fault Action as desired.
• Default: None
Restriction
If you set Process Variable Fault Action to NAN, you cannot set mA Output Fault Action or Frequency
Output Fault Action to None. If you try to do this, the transmitter will not accept the configuration.
Important
• If you want the mA Output to continue reporting process data during fault conditions, you must set both
Process Variable Fault Action and mA Output Fault Action to None. If mA Output Fault Action is set to
None and Process Variable Fault Action is set to any other option, the mA Output will produce the signal
associated with the selection.
• If you want the Frequency Output to continue reporting process data during fault conditions, you must set
both Process Variable Fault Action and Frequency Output Fault Action to None. If Frequency Output
Fault Action is set to None and Process Variable Fault Action is set to any other option, the Frequency
Output will produce the signal associated with the selection.

6.6.2 Interaction between Process Variable Fault Action and other fault actions
The setting of Process Variable Fault Action affects the operation of the mA Outputs, Frequency Outputs,
and Discrete Outputs if the corresponding output fault actions are set to None.
Interaction between Process Variable Fault Action and mA Output Fault Action
If mA Output Fault Action is set to None, the mA Output signal depends on the setting of Process Variable
Fault Action.
If the device detects a fault condition:
1. Process Variable Fault Action is evaluated and applied.
2. mA Output Fault Action is evaluated.
• If it is set to None, the output reports the value associated with the setting of Process Variable
Fault Action.
• If it is set to any other option, the output performs the specified fault action.
If you want the mA Output to continue to report process data during fault conditions, you must set both mA
Output Fault Action and Process Variable Fault Action to None.
Interaction between Process Variable Fault Action and Frequency Output Fault Action
If Frequency Output Fault Action is set to None, the Frequency Output signal depends on the setting of
Process Variable Fault Action.
If the device detects a fault condition:
1. Process Variable Fault Action is evaluated and applied.
78 Micro Motion 4200 Transmitters
Configuration and Use Manual Configure advanced options for process measurement
MMI-20048166 April 2019
2. Frequency Output Fault Action is evaluated.
• If it is set to None, the output reports the value associated with the setting of Process Variable
Fault Action.
• If it is set to any other option, the output performs the specified fault action.
If you want the Frequency Output to continue to report process data during fault conditions, you must set
both Frequency Output Fault Action and Process Variable Fault Action to None.
Interaction between Process Variable Fault Action and Discrete Output Fault Action
If Discrete Output Fault Action is set to None and Discrete Output Source is set to Flow Rate Switch, the
discrete output state during a fault depends on the setting of Process Variable Fault Action.
If the device detects a fault condition:
1. Process Variable Fault Action is evaluated and applied.
2. Discrete Output Fault Action is evaluated.
• If it is set to None, and Discrete Output Source is set to Flow Rate Switch, the discrete output will
use the value determined by the current setting of Process Variable Fault Action to determine if a
flow rate switch has occurred.
• If Discrete Output Source is set to any other option, the setting of Process Variable Fault Action is
irrelevant to the behavior of the Discrete Output during fault conditions. The Discrete Output is set
to the specified fault action.
If you want the Discrete Output to report a flow rate switch appropriately during fault conditions, you must
set both Discrete Output Fault Action and Process Variable Fault Action to None.

• During the fault timeout period, the transmitter continues to report its last valid measurements.
• If the fault timeout period expires while the alert is still active, the fault actions are performed.
• If the alert condition clears before the fault timeout expires, no fault actions are performed.
Restriction
• Fault Timeout is not applied to all alerts. For some alerts, fault actions are performed as soon as the alert
condition is detected. See the list of alerts and conditions for details.
• Fault Timeout is applicable only when Alert Severity = Failure. For all other settings of Alert Severity,
Fault Timeout is irrelevant.
Procedure
Set Fault Timeout as desired.
• Default: 0 seconds
• Range: 0 to 60 seconds
If you set Fault Timeout to 0, fault actions are performed as soon as the alert condition is detected.

8.1 Configure the transmitter channels
Display Menu > Configuration > Inputs/Outputs > Channel x
ProLink Device Tools > Configuration > I/O > Channels > Channel x
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x
Your transmitter uses Channels A and B to support the control system and communications. Channel B is
configurable.
Depending on your purchase order, some channels may not be activated on your device. To see which
channels are activated:
• Using the display: Menu > About > Licenses
• Using ProLink: Device Information
• Using the Field Communicator: Overview > Device Information > Licenses > Permanent Feature Set >
Input/Output Channels
To activate additional channels, contact customer service.
Important
The channel configuration must match the I/O wiring.
Prerequisites
Plan your channel assignments before configuring channels. Not all combinations are supported. For
example:
• You cannot have two discrete outputs and a frequency output.
For details, see Channel combinations.
Important
To avoid causing process errors:
• Configure the channels before configuring the outputs.
• Before changing the channel configuration, ensure that all control loops affected by the channel are under
manual control.
Procedure
1. Identify the channels that are activated on your device.
2. For Channel B, if activated, set Channel Type as desired.
Configuration and Use Manual 93
Integrate the meter with the control system Configuration and Use Manual
April 2019 MMI-20048166
Channel Options
Channel B • mA Output 2
• Frequency Output 1 (default)
• Discrete Output 1
Restriction
You cannot configure Channel Type for Channel A and Channel B. Channel A is always mA Output 1.
Channel B is always mA Output 2.
Postrequisites
For each channel that you configured, perform or verify the corresponding output configuration. When the
configuration of a channel is changed, the channel's behavior will be controlled by the configuration that is
stored for the selected output type, and the stored configuration may not be appropriate for your process.
After verifying channel and output configuration, return the control loop to automatic control.
8.2 Configure the mA outputs
The mA outputs are used to report current values of process variables. The mA signal varies between 4 mA
and 20 mA in proportion to the current value of the assigned process variable.
Depending on your purchase order and channel configuration, your transmitter may have 1-2 mA outputs.
Channel A is always mA Output 1, and Channel B is always mA Output 2.
Note
Channel A also supports HART/Bell 202 communications, superimposed on the mA signal. HART is not
available on Channel B.

Range Value
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the mA Output, that is, to
define the relationship between mA Output Process Variable and the mA Output signal.
LRV is the value of mA Output Source represented by an output of 4 mA. URV is the value of mA Output
Source represented by an output of 20 mA. Between LRV and URV, the mA Output is linear with the process
variable. If the process variable drops below LRV or rises above URV, the transmitter posts an output
saturation alert.
Procedure
Set LRV and URV as desired.
Enter LRV and URV in the measurement units used for mA Output Source.
• Defaults: Specific to each process variable
• Range: Unlimited
Note
You can set URV below LRV. For example, you can set URV to 50 and LRV to 100. If you do this, the mA
Output will be inversely proportional to the value of mA Output Source.
Tip
For best performance:
• Set LRV ≥ LSL (lower sensor limit).
• Set URV ≤ USL (upper sensor limit).
• Set these values so that the difference between URV and LRV is ≥ Min Span (minimum span).

Configuration and Use Manual Integrate the meter with the control system
MMI-20048166 April 2019
This ensures that the resolution of the mA output signal is within the range of the bit precision of the D/A
converter.
Note
The transmitter always stores LRV and URV for the current process variable and the previous process variable.
If mA Output Source is set to Mass Flow Rate and you set LRV and URV for this configuration, then you
change mA Output Source to Volume Flow Rate and set LRV and URV, then change mA Output Source back
to Mass Flow Rate, the corresponding LRV and URV are restored automatically. However, if you changed mA
Output Source to Volume Flow Rate, then to Phase Genius Flow Severity, and then back to Mass Flow Rate,
the configured LRV and URV for Mass Flow Rate are no longer available. The sensor's lower limit and upper
limit are used instead.

Effect of mA Output Direction on an mA Output
mA Output Direction affects how the transmitter reports flow values via an mA Output. An mA Output is
affected by mA Output Direction only if mA Output Source is set to a flow variable.
The effect of mA Output Direction depends on the setting of Lower Range Value (LRV).
• If Lower Range Value = 0, see Figure 8-1.
• If Lower Range Value > 0, see Figure 8-1 and adapt the chart.
• If Lower Range Value < 0, see Figure 8-2.

• Under conditions of forward flow, up to a flow rate of 100 g/sec, the mA Output varies between 4 mA and
20 mA in proportion to the flow rate.
• Under conditions of forward flow, if the flow rate equals or exceeds 100 g/sec, the mA Output will be
proportional to the flow rate up to 20.5 mA, and will be level at 20.5 mA at higher flow rates.

• Under conditions of forward flow, if (the absolute value of) the flow rate equals or exceeds 100 g/sec, the
mA Output is proportional to the flow rate up to 20.5 mA, and will be level at 20.5 mA at higher flow rates.
• Under conditions of reverse flow, for flow rates between 0 and −100 g/sec, the mA Output varies between
4 mA and 12 mA in inverse proportion to the absolute value of the flow rate.
• Under conditions of reverse flow, if the absolute value of the flow rate equals or exceeds 100 g/sec, the mA
Output is inversely proportional to the flow rate down to 3.8 mA, and will be level at 3.8 mA at higher
absolute values.
8.2.4 Configure mA Output Cutoff

ProLink III Device Tools > Configuration > I/O > Outputs > mA Output x > Flow Rate Cutoff
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x > mA Output x > mA Output x Settings > mAO
Flow Rate Cutoff
mA Output Cutoff specifies the lowest flow rate that will be reported through the mA Output. All flow rates
below the specified value are reported as 0.
mA Output Cutoff is applicable only when mA Output Source is set to a flow rate variable. It is applied to all
flow rate variables: mass flow rate, liquid volume flow rate, gas standard volume flow rate, and so on.
Procedure
Set mA Output Cutoff as desired.
Set mA Output Cutoff in the measurement units used for the process variable. If you change the
measurement unit, mA Output Cutoff is adjusted automatically.
• Default: 0
• Range: 0 or any positive value
Tip
For most applications the default value of mA Output Cutoff should be used. Contact customer service
before changing mA Output Cutoff.
Interaction between mA Output Cutoff and process variable cutoffs
When mA Output Process Variable is set to a flow variable (for example, mass flow rate or volume flow rate),
mA Output Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The transmitter puts the cutoff
into effect at the highest flow rate at which a cutoff is applicable.
