Configuration and Use Manual21
Using a DeviceNet Tool
For complete documentation of the Model 2400S DN transmitter’s device profile, including input and
output assemblies, see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.
5.4Using a DeviceNet tool
Micro Motion supplies an Electronic Data Sheet (EDS) for the Model 2400S transmitter. The EDS
file is named
MMI2400S-MassFlow.eds. The EDS presents the device profile in a format designed to
be read and interpreted by other devices.
DeviceNet tools fall into two basic categories:
•Type A: Tools that use the EDS to build a unique user interface for the specific device
•Type B: Tools that do not use the EDS, and instead rely on the user to supply the
object-instance-attribute information required to interact with the device
5.4.1Type A tools
If you are using a Type A tool:
1. Use your tool’s standard methods to read or import the supplied EDS into the network
configuration tool (e.g., RSLinx).
2. Use your tool’s standard user interface to configure, view, and manage the transmitter.
3. If you want to perform a function that isn’t available through your tool, see the instructions for
Type B tools.
5.4.2Type B tools
If you are using a Type B tool, or if you want to access features that are not available through your
tool’s user interface, you must reference the feature by class, instance, and attribute, use the
appropriate service, and supply an attribute value if required. Depending on the attribute, the value
may be a numeric or character value or a code. Values must be entered in the data type appropriate to
the attribute.
For example:
•To configure the mass flow cutoff, you must:
a.Specify the Analog Input Point class.
b.Specify the Mass Flow instance.
c.Specify the cutoff attribute.
d.Use the Set service to set the attribute value to the desired cutoff.
•To read the mass flow process variable, you can use either of the following methods:
-Use the Get service to read the value of the corresponding attribute.
-Use one of the input assemblies that contains the mass flow process variable.
This manual provides class, instance, attribute, data type, and service information for most
configuration parameters and for all procedures. Complete documentation of the Model 2400S DN
transmitter’s device profile is provided in the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile.

Required Transmitter Configuration
6.1Overview
This chapter describes the configuration procedures that are usually required when a transmitter is
installed for the first time.
The following procedures are discussed:
•Characterizing the flowmeter – see Section 6.2
•Configuring measurement units – see Section 6.3
This chapter provides basic flowcharts for each procedure. For more detailed flowcharts, see the
flowcharts for your communication tool, provided in the appendices to this manual.
For optional transmitter configuration parameters and procedures, see Chapter 8.
Note: All ProLink II procedures provided in this chapter assume that you have established
communication between ProLink II and the Model 2400S DN transmitter and that you are complying
with all applicable safety requirements. See Chapter 4 for more information.

Note: All DeviceNet tool procedures provided in this chapter assume that you have established
communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are
complying with all applicable safety requirements. See Chapter 5 for more information.
6.2Characterizing the flowmeter
Characterizing the flowmeter adjusts the transmitter to compensate for the unique traits of the sensor
it is paired with. The characterization parameters, or calibration factors, describe the sensor’s
sensitivity to flow, density, and temperature.
6.2.1When to characterize
If the transmitter and sensor were ordered together, then the flowmeter has already been
characterized. You need to characterize the flowmeter only if the transmitter and sensor are being
paired together for the first time.
6.2.2Characterization parameters
The characterization parameters that must be configured depend on your flowmeter’s sensor type:
“T-Series” or “Other” (also referred to as “Straight Tube” and “Curved Tube,” respectively), as listed
in Table 6-1. The “Other” category includes all Micro Motion sensors except T-Series.
The characterization parameters are provided on the sensor tag. See Figure 6-1 for illustrations of
sensor tags.

Flow calibration values
Two factors are used to define flow calibration:
•The flow calibration factor, which is a 6-character string (five numbers and a decimal point)
•The temperature coefficient for flow, which is a 4-character string (three numbers and a
decimal point)
These values are concatenated on the sensor tag, but different labels are used for different sensors. As
shown in Figure 6-1:
•For T-Series sensors, the value is called the FCF value.
•For other sensors, the value is called the Flow Cal value.

6.3Configuring the measurement units
For each process variable, the transmitter must be configured to use the measurement unit appropriate
to your application.
To configure measurement units for process variables, see the menu flowcharts in Figure 6-3. For
details on measurement units for each process variable, see Sections 6.3.1 through 6.3.4.
The measurement units used for totalizers and inventories are assigned automatically, based on the
measurement unit configured for the corresponding process variable. For example, if
per hour) is configured for mass flow, the unit used for the mass flow totalizer and mass flow
inventory is
kg (kilograms). DeviceNet codes used for the measurement units are listed in Tables C-12
through C-14.
Note: Pressure unit configuration is required only if you are using pressure compensation (see
Section 9.2) or you are using the Gas Wizard and you need to change the pressure units (see
Section 8.2).

procedures are discussed:
•Recording process variables – see Section 7.2
•Viewing process variables – see Section 7.3
•Viewing transmitter status and alarms – see Section 7.5
•Handling status alarms – see Section 7.6
•Viewing and controlling the totalizers and inventories – see Section 7.7

7.2Recording process variables
Micro Motion suggests that you make a record of the process variables listed below, under normal
operating conditions. This will help you recognize when the process variables are unusually high or
low, and may help in fine-tuning transmitter configuration.
Record the following process variables:
•Flow rate
•Density
•Temperature
•Tube frequency
•Pickoff voltage
•Drive gain
To view these values, see Section 7.3. For information on using this information in troubleshooting,
see Section 11.13.
Configuration and Use Manual35
Using the Transmitter
7.3Viewing process variables
Process variables include measurements such as mass flow rate, volume flow rate, mass total, volume
total, temperature, and density.
You can view process variables with the display (if your transmitter has a display), ProLink II, or a
DeviceNet tool.
Note: If the petroleum measurement application is enabled, two of the API process variables are
averages: Batch Weighted Average Density and Batch Weighted Average Temperature. For both of
these, the averages are calculated for the current totalizer period, i.e., since the last reset of the API
volume totalizer.
7.3.1With the display
By default, the display shows the mass flow rate, mass total, volume flow rate, volume total,
temperature, density, and drive gain. If desired, you can configure the display to show other process
variables. See Section 8.9.5.
The LCD panel reports the abbreviated name of the process variable (e.g.,
current value of that process variable, and the associated unit of measure (e.g.,
Appendix D for information on the codes and abbreviations used for display variables.
To view a process variable with the display:
•If Auto Scroll is enabled, wait until the desired process variable appears on the LCD panel.
DENS for density), the
G/CM3). See
•If Auto Scroll is not enabled,
Scroll until the name of the desired process variable either:
-Appears on the process variable line, or
-Begins to alternate with the units of measure
See Figure 3-2.
The display precision can be configured separately for each process variable (see Section 8.9.5). This
affects only the value shown on the display, and does not affect the actual value as reported by the
transmitter via digital communications.
Process variable values are displayed using either standard decimal notation or exponential notation:
•Values smaller than 100,000,000 are displayed in decimal notation (e.g.,
•Values greater than 100,000,000 are displayed using exponential notation (e.g.,
1234567.89).
1.000E08).
-If the value is less than the precision configured for that process variable, the value is
displayed as
0 (i.e., there is no exponential notation for fractional numbers).
-If the value is too large to be displayed with the configured precision, the displayed
precision is reduced (i.e., the decimal point is shifted to the right) as required so that the
value can be displayed.
7.3.2With ProLink II
The Process Variables window opens automatically when you first connect to the transmitter. This
window displays current values for the standard process variables (mass, volume, density,
temperature, external pressure, and external temperature).
To view the standard process variables with ProLink II, if you have closed the Process Variables
window, click

7.5Viewing transmitter status
You can view transmitter status using the status LED, ProLink II, or a DeviceNet tool. Depending on
the method chosen, different information is displayed.
7.5.1Using the status LED
The status LED shows transmitter status as described in Table 7-5. Note that the status LED does not
report event status or alarm status for alarms with severity level set to Ignore (see Section 8.8).

•Event status
•Assorted other transmitter data
Required ConfigurationOptional ConfigurationUsing the TransmitterUsing a DeviceNet Tool
7.5.3Using a DeviceNet tool
Status information is located in the Diagnostics Object (0x66), Instance 1. This Object includes,
among other data:
•Alarm status (Attributes 12–17, Attributes 40–41)
•Event status (Attribute 11)
•Drive gain (Attribute 20)
•Tube frequency (Attribute 21)
•Left and right pickoff voltages (Attributes 23 and 24)
Use the Get service to read the required data. See Table C-7, or see the manual entitled Micro Motion Model 2400S Transmitters for DeviceNet: Device Profile for detailed information.
7.6Handling status alarms
Specific process or flowmeter conditions cause status alarms. Each status alarm has an alarm code.
Status alarms are classified into three severity levels: Fault, Information, and Ignore. Severity level
controls how the transmitter responds to the alarm condition.
Note: Some status alarms can be reclassified, i.e., configured for a different severity level. For
information on configuring severity level, see Section 8.8.
Note: For detailed information on a specific status alarm, including possible causes and
troubleshooting suggestions, see Table 11-2. Before troubleshooting status alarms, first acknowledge
all alarms. This will remove inactive alarms from the list so that you can focus troubleshooting efforts
on active alarms.
The transmitter maintains two status flags for each alarm:
•The first status flag indicates “active” or “inactive.”
•The second status flag indicates “acknowledged” or “unacknowledged.”
Configuration and Use Manual43
Using the Transmitter
In addition, the transmitter maintains alarm history for the 50 most recent alarm occurrences. Alarm
history includes:
•The alarm code
•The “alarm active” timestamp
•The “alarm inactive” timestamp
•The “alarm acknowledged” timestamp
When the transmitter detects an alarm condition, it checks the severity level of the specific alarm and
performs the actions described in Table 7-6.

When the transmitter detects that the alarm condition has cleared:
•The first status flag is set to “inactive.”
•Digital communications fault action is deactivated (Fault alarms only).
•The “alarm inactive” record is written to alarm history (Fault and Informational alarms only).
•The second status flag is not changed.
Operator action is required to return the second status flag to “acknowledged.” Alarm
acknowledgment is not necessary. If the alarm is acknowledged, the “alarm acknowledged” record is
written to alarm history.
7.6.1Using the display
The display shows information only about active Fault or Informational alarms, based on alarm status
bits. Ignore alarms are filtered out, and you cannot access alarm history via the display.
To view or acknowledge alarms using the display menus, see the flowchart in Figure 7-1.
If the transmitter does not have a display, or if operator access to the alarm menu is disabled (see
Section 8.9.3), alarms can be viewed and acknowledged using ProLink II or a DeviceNet tool. Alarm
acknowledgment is not required.
Additionally, the display may be configured to enable or disable the Ack All function. If disabled, the
Ack All screen is not displayed and alarms must be acknowledged individually.

7.6.2Using ProLink II
ProLink II provides two ways to view alarm information:
•The Status window
•The Alarm Log window
Status window
The Status window displays the current status of the alarms considered to be most useful for
information, service, or troubleshooting, including Ignore alarms. The Status window reads alarm
status bits, and does not access alarm history. The Status window does not display acknowledgment
information, and you cannot acknowledge alarms from the Status window.
Configuration and Use Manual45
Using the Transmitter
In the Status window:
•Alarms are organized into three categories: Critical, Informational, and Operational. Each
category is displayed on a separate panel.
•If one or more alarms is active on a panel, the corresponding tab is red.
•On a panel, a green LED indicates “inactive” and a red LED indicates “active.”
Note: The location of alarms on the Status panels is pre-defined, and is not affected by alarm severity.
To use the Status window:

7.7Using the totalizers and inventories
The totalizers keep track of the total amount of mass or volume measured by the transmitter over a
period of time.
The inventories track the same values as the totalizers. Whenever totalizers are started or stopped, all
inventories (including the API volume inventory and concentration measurement inventories) are
started or stopped automatically. However, when totalizers are reset, inventories are not reset
automatically – you must reset inventories separately. This allows you to use the inventories to keep
running totals across multiple totalizer resets.
You can view all totalizer and inventory values using any of the communication tools: the display,
ProLink II, or a DeviceNet tool. Specific starting, stopping, and resetting functionality depends on the
tool you are using.

8.2Configuring volume flow measurement for gas
Two types of volume flow measurement are available:
•Liquid volume (the default)
•Gas standard volume
Only one type of volume flow measurement can be performed at a time (i.e., if liquid volume flow
measurement is enabled, gas standard volume flow measurement is disabled, and vice versa).
Different sets of volume flow measurement units are available, depending on which type of volume
flow measurement is enabled (see Tables 6-3 and 6-4). If you will use a gas standard volume flow
unit, additional configuration is required.
Note: If you will use the petroleum measurement application or the concentration measurement
application, liquid volume flow measurement is required.
The method used to configure volume flow measurement for gas depends on the tool you are using:
ProLink II or a DeviceNet tool.
Note: For complete configuration of volume flow measurement for gas, you must use either ProLink II
or a DeviceNet tool. Using the display, you can only select a volume measurement unit from the set
available for the configured volume flow type.

Optional Configuration
8.3.1Cutoffs and volume flow
If you are using liquid volume flow measurement:
•The density cutoff is applied to the volume flow calculation. Accordingly, if the density drops
below its configured cutoff value, the volume flow rate will go to zero.
•The mass flow cutoff is not applied to the volume flow calculation. Even if the mass flow
drops below the cutoff, and therefore the mass flow indicators go to zero, the volume flow rate
will be calculated from the actual mass flow process variable.
If you are using gas standard volume flow measurement, neither the mass flow cutoff nor the density
cutoff is applied to the volume flow calculation.
8.4Configuring the damping values
A damping value is a period of time, in seconds, over which the process variable value will change to
reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small,
rapid measurement fluctuations.
•A high damping value makes the output appear to be smoother because the output must change
slowly.
•A low damping value makes the output appear to be more erratic because the output changes
more quickly.
Damping can be configured for flow, density, and temperature.
When you change the damping value, the specified value is automatically rounded down to the nearest
valid damping value. Valid damping values are listed in Table 8-3.
Note: For gas applications, Micro Motion recommends a minimum flow damping value of 2.56.
Before setting the damping values, review Section 8.4.1 for information on how the damping values
affect other transmitter measurements.

8.4.1Damping and volume measurement
When configuring damping values, note the following:
•Liquid volume flow is derived from mass and density measurements; therefore, any damping
applied to mass flow and density will affect liquid volume measurement.
•Gas standard volume flow is derived from mass flow measurement, but not from density
measurement. Therefore, only damping applied to mass flow will affect gas standard volume
measurement.
Be sure to set damping values accordingly.
8.5Configuring the flow direction parameter
The flow direction parameter controls how the transmitter reports flow rate and how flow is added to
or subtracted from the totalizers, under conditions of forward flow, reverse flow, or zero flow.
•Forward (positive) flow moves in the direction of the arrow on the sensor.
•Reverse (negative) flow moves in the direction opposite of the arrow on the sensor.
The options for flow direction and their effects on flow values and flow totals are shown in Table 8-4.

8.6Configuring events
An event occurs if the real-time value of a user-specified process variable varies above or below a
user-specified value, or inside or outside a user-specified range. You can configure up to five events.
You may optionally specify one or more actions that will occur if the event occurs. For example, if
Event 1 occurs, you may specify that the transmitter will stop all totalizers and inventories and reset
the mass totalizer.
8.6.1Defining events
To define an event:
•Using ProLink II, see Figure B-3.
•Using a DeviceNet tool, event specifications reside in the Diagnostics Object (0x66),
Instance 1. See Table C-7.
The following general steps are required:
1. Select the event to define (Attribute 6).
2. Specify the event type (Attribute 7). Event Type options are defined in Table 8-5.
3. Assign a process variable to the event (Attribute 10).
4. Specify the event’s setpoint(s) – the value(s) at which the event will occur or switch state (ON
to OFF, or vice versa).
•If Event Type is High or Low, only Setpoint A is used (Attribute 8)
•If Event Type is In Range or Out of Range, both Setpoint A and Setpoint B (Attributes 9
and 10) are required.
5. Assign the event to an action or actions, if desired. Possible actions are listed in Table 8-6. To
do this:
•Using ProLink II, open the Discrete Input panel in the Configuration window, identify the
action to be performed, then specify the event using the drop-down list. See Figure B-3.
Note: For consistency with other Micro Motion products, the Discrete Input panel is used here even
though the Model 2400S DN transmitter does not provide a discrete input.
•Using the display, see Figure B-6 and use the ACT submenu.
•Using a DeviceNet tool, refer to Table C-7, use Attribute 84 to specify the action to be
performed, and set Attribute 85 to specify which event will initiate the action.

2. Configure the Flow Direction parameter for bidirectional flow. See
Section 8.5.
3. Select Event 1.
4. Configure:
•Event Type = Low
•Process Variable (PV) = Mass Flow Rate
•Low Setpoint (A) = 2
5. In the Discrete Input panel, open the drop-down list for Start/Stop
All Totalization and select Discrete Event 1.
Using a DeviceNet tool:
1. Specify lb/min as the mass flow unit. See Section 6.3.1.
2. Configure the Flow Direction parameter for bidirectional flow. See
Section 8.5.
3. In the Diagnostics Object (0x66), Instance 1, set the following
attributes:
•Discrete event index (Attribute 6) = 0
•Discrete event action (Attribute 7) = 1
•Discrete event process variable (Attribute 10) = 0
•Discrete event setpoint A (Attribute 8) = 2
•Discrete event action code (Attribute 84) = 9
•Discrete event assignment (Attribute 85) = 57
8.6.2Checking and reporting event status
There are several ways that event status can be determined:
•ProLink II automatically displays event information on the Informational panel of the Status
window.
•The status of each event is stored in the Diagnostics Object (0x66), Instance 1, Attribute 11.

8.7Configuring slug flow limits and duration
Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications.
The presence of slugs can significantly affect the process density reading. The slug flow parameters
can help the transmitter suppress extreme changes in process variables, and can also be used to
identify process conditions that require correction.
Slug flow parameters are as follows:
•Slug flow low limit – the point below which a condition of slug flow will exist. Typically, this
is the lowest density point in your process’s normal density range. Default value is
range is
0.0–10.0 g/cm
3
.
•Slug flow high limit – the point above which a condition of slug flow will exist. Typically, this
is the highest density point in your process’s normal density range. Default value is
range is
0.0–10.0 g/cm
3
.
•Slug flow duration – the number of seconds the transmitter waits for a slug flow condition
(outside the slug flow limits) to return to normal (inside the slug flow limits). Default value is
0.0 sec; range is 0.0–60.0 sec.
Scroll to the mass total screen.

;
If the transmitter detects slug flow:
•A slug flow alarm is posted immediately.
•During the slug duration period, the transmitter holds the mass flow rate at the last measured
pre-slug value, independent of the mass flow rate measured by the sensor. The reported mass
flow value is set to this value, and all internal calculations that include mass flow rate will use
this value.
•If slugs are still present after the slug duration period expires, the transmitter forces the mass
flow rate to
reported as
0, independent of the mass flow rate measured by the sensor. Mass flow rate is
0 and all internal calculations that include mass flow rate will use 0.
•When process density returns to a value within the slug flow limits, the slug flow alarm is
cleared and the mass flow rate reverts to the actual measured value.
Configuration and Use Manual65
Optional Configuration
To configure slug flow parameters:
•Using ProLink II, use the Density panel in the Configuration window. See Figure B-2.
•Using a DeviceNet tool, set Attributes 3, 4, and 5 in the Diagnostics Object (0x66), Instance 1.
See Table C-7.
Note: This functionality is not available via the display menus.
Note: The slug flow limits must be entered in g/cm
density. Slug flow duration is entered in seconds.
Note: Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility
of slug flow conditions. Conversely, lowering the low slug flow limit or raising the high slug flow limit
will decrease the possibility of slug flow conditions.
Note: If slug flow duration is set to 0, the mass flow rate will be forced to 0 as soon as slug flow is
detected.
8.8Configuring status alarm severity
The Model 2400S transmitter can report faults in the following ways:
•Setting the “alarm active” status bit
•Writing an “alarm active” record to alarm history

8.10.4Modbus address
Note: The Modbus address is applicable only when you are connecting to the service port from a tool
that uses Modbus protocol. After initial startup, service port connections are typically used only for
troubleshooting or for specific procedures such as temperature calibration. ProLink II is typically
used for service port connections, and by default ProLink II will use the standard service port address
rather than the configured Modbus address. See Section 4.4 for more information.
The set of valid Modbus addresses depends on whether or not support for Modbus ASCII is enabled
or disabled (see Section 8.10.5). Valid Modbus addresses are as follows:
•Modbus ASCII enabled:
1–15, 32–47, 64–79, 96–110
•Modbus ASCII disabled: 0–127
To configure the Modbus address:
•Using ProLink II, see Figure B-2.
•Using the display menus, see Figure B-6.

When support for Modbus ASCII is enabled, the service port can accept connection requests that use
either Modbus ASCII or Modbus RTU. When support for Modbus ASCII is disabled, the service port
cannot accept connection requests that use Modbus ASCII. Only Modbus RTU connections are
accepted.
The primary reason to disable Modbus ASCII support is to allow a wider range of Modbus addresses
for the service port.
To enable or disable Modbus ASCII support:
•Using ProLink II, see Figure B-2.
•Using the display menus, see Figure B-6.
8.10.6IrDA port usage
The IrDA port on the display can be enabled or disabled. If enabled, it can be set for read-only or
read/write access.
To enable or disable the IrDA port:
•Using ProLink II, see Figure B-2.
•Using the display menus, see Figure B-6.
•Using a DeviceNet tool, see Table C-9.
To configure the IrDA port for read-only or read-write access:
•Using ProLink II, see Figure B-2.

8.10.7Digital communications fault action
Digital communications fault action controls how digital communications will be affected by fault
conditions. Table 8-12 lists the options for digital communications fault action.
Note: Digital communications fault action does not affect the alarm status bits. For example, if digital
communications fault action is set to None, the alarm status bits will still be set if an alarm occurs.

8.10.8Fault timeout
By default, the transmitter activates the digital communications fault action as soon as the fault is
detected. The fault timeout allows you to delay the digital communications fault action for a specified
interval, for certain faults only. During the fault timeout period, digital communications behaves
normally.
Note: The fault timeout applies only to the digital communications fault action. The “alarm active”
status bit is set as soon as the fault is detected (all alarm severity levels), and the “alarm active”
record is written to history immediately (Fault and Informational alarms only). For more information
on alarm handling, see Section 7.6. For more information on alarm severity, see Section 8.8.
The fault timeout applies only to specific faults. Other faults are reported immediately, regardless of
the fault timeout setting. For information on which faults are affected by the fault timeout, see
Tabl e 8-8.

parameters are available only if the petroleum measurement application is enabled on your
transmitter.
Note: The petroleum measurement application requires liquid volume measurement units. If you plan
to use API process variables, ensure that liquid volume flow measurement is specified. See
Section 8.2.
8.13.1About the petroleum measurement application
Some applications that measure liquid volume flow or liquid density are particularly sensitive to
temperature factors, and must comply with American Petroleum Institute (API) standards for
measurement. The petroleum measurement enables Correction of Temperature on volume of Liquids,
or CTL.

Optional Configuration
Terms and definitions
The following terms and definitions are relevant to the petroleum measurement application:
•API – American Petroleum Institute
•CTL – Correction of Temperature on volume of Liquids. The CTL value is used to calculate
the VCF value
•TEC – Thermal Expansion Coefficient
•VCF – Volume Correction Factor. The correction factor to be applied to volume process
variables. VCF can be calculated after CTL is derived
CTL derivation methods
There are two derivation methods for CTL:
•Method 1 is based on observed density and observed temperature.
•Method 2 is based on a user-supplied reference density (or thermal expansion coefficient, in
some cases) and observed temperature.
API reference tables
Reference tables are organized by reference temperature, CTL derivation method, liquid type, and
density unit. The table selected here controls all the remaining options.

8.14Configuring the concentration measurement application
Micro Motion sensors provide direct measurements of density, but not of concentration. The
concentration measurement application calculates concentration measurement process variables, such
as concentration or density at reference temperature, from density process data, appropriately
corrected for temperature.
Note: For a detailed description of the concentration measurement application, see the manual
entitled Micro Motion Enhanced Density Application: Theory, Configuration, and Use.
Note: The concentration measurement application requires liquid volume measurement units. If you
plan to use concentration measurement process variables, ensure that liquid volume flow
measurement is specified. See Section 8.2.
8.14.1About the concentration measurement application
The concentration measurement calculation requires an concentration measurement curve, which
specifies the relationship between temperature, concentration, and density for the process fluid being
measured. Micro Motion supplies a set of six standard concentration measurement curves (see
Table 8-16). If none of these curves is appropriate for your process fluid, you can configure a custom
curve or purchase a custom curve from Micro Motion.
The derived variable, specified during configuration, controls the type of concentration measurement
that will be produced. Each derived variable allows the calculation of a subset of concentration
measurement process variables (see Table 8-17). The available concentration measurement process
variables can be used in process control, just as mass flow rate, volume flow rate, and other process
variables are used. For example, an event can be defined on an concentration measurement process
variable.
•For all standard curves, the derived variable is Mass Conc (Dens).
•For custom curves, the derived variable may be any of the variables listed in Table 8-17.

Pressure Compensation
and Temperature Compensation
9.1Overview
This chapter describes the following procedures:
•Configuring pressure compensation – see Section 9.2
•Configuring external temperature compensation – see Section 9.3
•Obtaining external pressure or temperature data – see Section 9.4
Note: All ProLink II procedures provided in this chapter assume that you have established
communication between ProLink II and the Model 2400S DN transmitter and that you are complying
with all applicable safety requirements. See Chapter 4 for more information.
Note: All DeviceNet tool procedures provided in this chapter assume that you have established
communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are
complying with all applicable safety requirements. See Chapter 5 for more information.
9.2Pressure compensation
The Model 2400S DN transmitter can compensate for the effect of pressure on the sensor flow tubes.
Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure
change away from calibration pressure.
Note: Pressure compensation is an optional procedure. Perform this procedure only if required by
your application.
There are two ways to configure pressure compensation:
•If the operating pressure is a known static value, you can configure that value in the
transmitter.
•If the operating pressure varies significantly, you must write a pressure value to the transmitter
at appropriate intervals, using an appropriate output assembly. See Section 9.4.
Note: Ensure that your pressure value is accurate, or that your pressure measurement device is
accurate and reliable.

Two additional pressure correction factors may be configured: one for flow and one for density. These
are defined as follows:
•Flow factor – the percent change in the flow rate per psi
•Density factor – the change in fluid density, in g/cm
Not all sensors or applications require pressure correction factors. For the pressure correction values
to be used, obtain the pressure effect values from the product data sheet for your sensor, then reverse
the signs (e.g., if the pressure effect is
0.000004, enter a pressure correction factor of –0.000004).

•Meter validation and adjusting meter factors – see Section 10.4
•Zero calibration – see Section 10.5
•Density calibration – see Section 10.6
•Temperature calibration – see Section 10.7
Note: All ProLink II procedures provided in this chapter assume that you have established
communication between ProLink II and the Model 2400S DN transmitter and that you are complying
with all applicable safety requirements. See Chapter 4 for more information.
Note: All DeviceNet tool procedures provided in this chapter assume that you have established
communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are
complying with all applicable safety requirements. See Chapter 5 for more information.
10.2Meter validation, Smart Meter Verification, and calibration
The Model 2400S transmitter supports the following procedures for the evaluation and adjustment of
measurement performance:
•Smart Meter Verification – establishing confidence in the sensor’s performance by analyzing
secondary variables associated with flow and density
•Meter validation – confirming performance by comparing the sensor’s measurements to a
primary standard
•Calibration – establishing the relationship between a process variable (flow, density, or
temperature) and the signal produced by the sensor
Meter validation and calibration are available on all Model 2400S DN transmitters. Smart Meter
Verification is available only if the Smart Meter Verification option was ordered with the transmitter.
These three procedures are discussed and compared in Sections 10.2.1 through 10.2.4. Before
performing any of these procedures, review these sections to ensure that you will be performing the
appropriate procedure for your purposes.
Configuration and Use Manual89
Measurement Performance
10.2.1Smart Meter Verification
Smart Meter Verification evaluates the structural integrity of the sensor tubes by comparing current
tube stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit
deflection, or force divided by displacement. Because a change in structural integrity changes the
sensor’s response to mass and density, this value can be used as an indicator of measurement
performance. Changes in tube stiffness are typically caused by erosion, corrosion, or tube damage.
Smart Meter Verification does not affect measurement in any way. Micro Motion recommends
performing Smart Meter Verification at regular intervals.
10.2.2Meter validation and meter factors
Meter validation compares a measurement value reported by the transmitter with an external
measurement standard. Meter validation requires one data point.
Note: For meter validation to be useful, the external measurement standard must be more accurate
than the sensor. See the sensor’s product data sheet for its accuracy specification.
If the transmitter’s mass flow, volume flow, or density measurement is significantly different from the
external measurement standard, you may want to adjust the corresponding meter factor. A meter
factor is the value by which the transmitter multiplies the process variable value. The default meter
factors are
1.0, resulting in no difference between the data retrieved from the sensor and the data
reported externally.
Meter factors are typically used for proving the flowmeter against a weights and measures standard.
You may need to calculate and adjust meter factors periodically to comply with regulations.
10.2.3Calibration
The flowmeter measures process variables based on fixed points of reference. Calibration adjusts
those points of reference. Three types of calibration can be performed:
•Zero, or no flow
•Density calibration
•Temperature calibration
Density and temperature calibration require two data points (low and high) and an external
measurement for each. Zero calibration requires one data point. Calibration produces a change in the
offset and/or the slope of the line that represents the relationship between the actual process value and
the reported value.
Note: For density or temperature calibration to be useful, the external measurements must be
accurate.
Micro Motion flowmeters with the Model 2400S transmitter are calibrated at the factory, and
normally do not need to be calibrated in the field. Calibrate the flowmeter only if you must do so to
meet regulatory requirements. Contact Micro Motion before calibrating your flowmeter.
Note: Micro Motion recommends using meter validation and meter factors, rather than calibration, to
prove the meter against a regulatory standard or to correct measurement error.

Measurement Performance
10.2.4Comparison and recommendations
When choosing among Smart Meter Verification, meter validation, and calibration, consider the
following factors:
•Process and measurement interruption
-Smart Meter Verification provides an option that allows process measurement to continue
during the test.
-Meter validation for density does not interrupt the process. However, meter validation for
mass flow or volume flow requires process down-time for the length of the test.
-Calibration requires process down-time. In addition, density and temperature calibration
require replacing the process fluid with low-density and high density fluids, or
low-temperature and high-temperature fluids. Zero calibration requires stopping flow
through the sensor.
•External measurement requirements
-Smart Meter Verification does not require external measurements.
-Zero calibration does not require external measurements.
-Density calibration, temperature calibration, and meter validation require external
measurements. For good results, the external measurement must be highly accurate.
•Measurement adjustment
-Smart Meter Verification is an indicator of sensor condition, but does not change
flowmeter internal measurement in any way.
-Meter validation does not change flowmeter internal measurement in any way. If you
decide to adjust a meter factor as a result of a meter validation procedure, only the reported
measurement is changed – the base measurement is not changed. You can always reverse
the change by returning the meter factor to its previous value.
-Calibration changes the transmitter’s interpretation of process data, and accordingly
changes the base measurement. If you perform a zero calibration, you can return to the
previous zero or the factory zero. However, if you perform a density calibration or a
temperature calibration, you cannot return to the previous calibration factors unless you
have manually recorded them.
Micro Motion recommends obtaining the Smart Meter Verification transmitter option and performing
Smart Meter Verification on a regular basis.
10.3Performing Smart Meter Verification
Note: To use Smart Meter Verification, the Smart Meter Verification option must be purchased for the
transmitter.
10.3.1Preparing for the Smart Meter Verification test
The Smart Meter Verification procedure can be performed on any process fluid. It is not necessary to
match factory conditions.
During the test, process conditions must be stable. To maximize stability:
•Maintain a constant temperature and pressure.
•Avoid changes to fluid composition (e.g., two-phase flow, settling, etc.).
•Maintain a constant flow. For higher test certainty, stop flow.
Configuration and Use Manual91
Measurement Performance
If stability varies outside test limits, the Smart Meter Verification procedure will be aborted. Verify
the stability of the process and retry the test.

Smart Meter Verification is not affected by any parameters configured for flow, density, or
temperature. It is not necessary to change the transmitter configuration.
Control loops and process measurement
If the transmitter outputs will be set to Last Measured Value or Fault during the test, the outputs will
be fixed for two minutes. Disable all control loops for the duration of the test, and ensure that any data
reported during this period is handled appropriately.
