Flowmeter Startup

2.1 Overview

This chapter describes the following procedures:

• Setting the node address – see Section 2.2

• Bringing the flowmeter online – see Section 2.3

2.2 Setting the node address

Three address switches are provided on the user interface module (see Figure 3-1 or Figure 3-2).
These switches are used to set a three-digit node address for the device:

• The leftmost switch sets the first digit.

• The center switch sets the second digit.

• The rightmost switch sets the third digit.

The default setting for the address switches is

You can set the node address manually before bringing the device online, by rotating the address
switches to any value between

Flowmeter Startup

WARNING

4. Apply power to the transmitter. The flowmeter will automatically perform diagnostic routines.

Note: If this is the initial startup, or if power has been off long enough to allow components to reach
ambient temperature, the flowmeter is ready to receive process fluid approximately one minute after
power-up. However, it may take up to ten minutes for the electronics in the flowmeter to reach thermal
equilibrium. During this warm-up period, you may observe minor measurement instability or
inaccuracy.

5. Ensure that the transmitter is visible on the network. For information on establishing

Operating the flowmeter without covers in place creates electrical hazards
that can cause death, injury, or property damage.

To avoid electrical hazards, ensure that the transmitter housing cover and all other
covers are in place before connecting the transmitter to the network.

When the flowmeter has completed its power-up sequence, the status LED will turn green. If
the status LED exhibits different behavior, an alarm condition is present or transmitter
calibration is in progress. See Section 7.6.

Startup Using ProLink IITransmitter User InterfaceBefore You Begin

- An internal termination resistor switch

- Three LEDs: a status LED, a network LED, and a software address LED

- Service port clips

- Zero button

For all other functions, either ProLink II or a customer-supplied PROFIBUS host is required.

• If ordered with a display, no zero button is provided (you must zero the transmitter with the
display menu, ProLink II, or a PROFIBUS host), and the following features are added:

- An LCD panel, which displays process variable data and also provides access to the

off-line menu for basic configuration and management. Optical switches are provided for
LCD control.

- An IrDA port which provides wireless access to the service port

• You must have Pocket ProLink v1.3 or higher.

• In addition:

- If you will connect to the transmitter via the service port clips, you must have either the

Pocket ProLink installation kit or the equivalent equipment. See the Pocket ProLink
manual or quick reference guide for details.

- If you will connect via the IrDA port, no additional equipment is required.

Configuration and Use Manual 17

Connecting with ProLink II or Pocket ProLink Software

4.3 Configuration upload/download

ProLink II and Pocket ProLink provide a configuration upload/download function which allows you
to save configuration sets to your PC. This allows:

• Easy backup and restore of transmitter configuration

• Easy replication of configuration sets

Micro Motion recommends that all transmitter configurations be saved to a PC as soon as the
configuration is complete. See Figure C-1, and refer to the ProLink II or Pocket ProLink manual for
details.

4.4 Connecting from a PC to a Model 2400S DP transmitter

To connect to the Model 2400S DP transmitter using ProLink II or Pocket ProLink, you must use a
service port connection.

4.4.1 Connection options

The service port can be accessed via the service port clips or the IrDA port.

The service port clips have priority over the IrDA port:

• If there is an active connection via the service port clips, access via the IrDA port is disabled.

• If there is an active connection via the IrDA port and a connection attempt is made via the
service port clips, the IrDA connection is terminated.

Additionally:

• Access via the IrDA port may be disabled altogether. In this case, it is not available for
connections at any time. By default, access via the IrDA port is disabled.

• The IrDA port may be write-protected. In this case, it can be used only to retrieve data from the
transmitter. By default, the IrDA port is write-protected.

See Section 8.10.2 for more information or to change these settings.

4.4.2 Service port connection parameters

The service port uses default connection parameters. Both ProLink II and Pocket ProLink
automatically use these default parameters when Protocol is set to Service Port.

Additionally, to minimize configuration requirements, the service port employs an auto-detection
scheme when responding to connection requests. The service port will accept all connection requests
within the limits described in Table 4-1. If you are connecting to the service port from another tool,
ensure that configuration parameters are set within these limits.

Note: Connections via the service port clips have priority over connections via the IrDA port. If you
are currently connected to the service port clips, you will not be able to connect via the IrDA port.

c. Position the IrDA device for communication with the IrDA port (see Figure 3-2). You do

not need to remove the transmitter housing cover.

Note: The IrDA port is typically used with Pocket ProLink. To use the IrDA port with ProLink II, a
special device is required; the IrDA port built into many laptop PCs is not supported. For more
information on using the IrDA port with ProLink II, contact Micro Motion customer service.

2. If you are using the service port clips:

a. Attach the signal converter to the serial or USB port of your PC, using the appropriate

connectors or adapters (e.g., a 25-pin to 9-pin adapter or a USB connector).

b. Remove the transmitter housing cover from the transmitter (see Section 3.3), then connect

the signal converter leads to the service port clips. See Figure 4-1.

Removing the transmitter housing cover in a hazardous area can cause an
explosion.

Because the transmitter housing cover must be removed to connect to the service
port clips, the service port clips should be used only for temporary connections, for
example, for configuration or troubleshooting purposes.

When the transmitter is in an explosive atmosphere, use a different method to
connect to your transmitter.

Required Transmitter Configuration

6.1 Overview

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 procedures provided in this chapter assume that you have established communication with

the Model 2400S DP transmitter and that you are complying with all applicable safety requirements.

Required Configuration Optional ConfigurationUsing the TransmitterUsing a PROFIBUS Host

Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.

6.2 Characterizing 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 parameters, describe the sensor’s
sensitivity to flow, density, and temperature.

6.2.1 When 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.

6.2.2 Characterization 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.

6.3 Configuring 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, 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

following is true:

• You will configure pressure compensation (see Section 9.2). In this case, configure the
pressure unit to match the pressure unit used by the external pressure device.

• You will use the Gas Wizard, you will enter a reference pressure value, and you need to change
the pressure unit to match the reference pressure value (see Section 8.2).

If you do not know whether or not you will use pressure compensation or the Gas Wizard, you do not
need to configure a pressure unit at this time. You can always configure the pressure unit later.

Using the Transmitter

7.1 Overview

This chapter describes how to use the transmitter in everyday operation. The following topics and
procedures are discussed:

• Using the I&M functions – see Section 7.2

• Recording process variables – see Section 7.3

• Viewing process variables – see Section 7.4

• Using the LEDs – see Section 7.5

• Viewing transmitter status and alarms – see Section 7.6

• Handling status alarms – see Section 7.7

• Viewing and using the totalizers and inventories – see Section 7.8

Note: All procedures provided in this chapter assume that you have established communication with
the Model 2400S DP transmitter and that you are complying with all applicable safety requirements.

Required Configuration Optional ConfigurationUsing the TransmitterUsing a PROFIBUS Host

Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.

7.2 Using the I&M functions

The Model 2400S DP transmitter implements the following PROFIBUS identification and
maintenance (I&M) functions:

•I&M 0

•I&M 1

as specified in Profile Guidelines Part 1: Identification & Maintenance Functions Version 1.1.1,

March 2005.

The I&M functions contain a variety of device and manufacturer information. Two of the I&M value
are set by the user during installation (see Section 8.12). The other values, including the Manufacturer
ID, are hard-coded. The Manufacturer ID stored on the transmitter can be used as a code to obtain
current device and manufacturer data from the PROFIBUS web site
(http://www.profibus.com/IM/Man_ID_Table.xml).

The I&M functions are not accessible via ProLink II or the display. If you are using Siemens Simatic
PDM, v6.0 SP2 or higher is required. Earlier versions do not support I&M functions.

Configuration and Use Manual 35

Using the Transmitter

To use the I&M functions:

1. Read the data from the transmitter:

• Using a PROFIBUS host with the EDD, connect to the transmitter as a Specialist. See
Figure C-12.

• Using PROFIBUS bus parameters, use the I&M Functions block (see Table D-9). You
must read the entire 64-byte dataset.

2. If desired, log onto the PROFIBUS web site and enter the Manufacturer ID code retrieved
from the transmitter.

7.3 Recording 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 7.4. For information on using this information in troubleshooting,
see Section 11.13.

7.4 Viewing 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
PROFIBUS host.

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.

7.4.1 With 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 8.9.3.

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.,

DENS for density), the

G/CM3). See

Appendix E for information on the codes and abbreviations used for display variables.

36 Micro Motion® Model 2400S Transmitters for PROFIBUS-DP

Using the Transmitter

To view a process variable with the display, refer to Figure 3-2 and:

• If Auto Scroll is enabled, wait until the desired process variable appears on the LCD panel.

• If Auto Scroll is not enabled,

- Appears on the process variable line, or

- Begins to alternate with the units of measure

The display precision can be configured separately for each process variable (see Section 8.9.3). 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 < 100,000,000 are displayed in decimal notation (e.g.,

•Values ≥ 100,000,000 are displayed using exponential notation (e.g.,

Scroll until the name of the desired process variable either:

1234567.8).

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.

7.4.2 With 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

To view API process variables (if the petroleum measurement application is enabled), click

• For all other process variables, use the Measurement block (see Table D-2)

7.5 Using the LEDs

The user interface module provides three LEDs: a status LED, a network LED, and a software address
LED (see Figures 3-1 and 3-2).

• For transmitters with a display, the LEDs can be viewed with the transmitter housing cover in
place.

• For transmitters without a display, the transmitter housing cover must be removed to view the
LEDs (see Section 3.3).

For information on:

• Using the network LED, see Section 7.5.1.

• Using the software address LED, see Section 7.5.2.

7.6.4 Using PROFIBUS bus parameters

Status information is located in the Diagnostic block (see Table D-4).

Configuration and Use Manual 39

Using the Transmitter

7.7 Handling 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 current “active” or “inactive” status.

• The second status flag indicates current “acknowledged” or “unacknowledged” status.

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 7-4.

40 Micro Motion® Model 2400S Transmitters for PROFIBUS-DP

Using the Transmitter

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 optional. If the alarm is acknowledged, the “alarm acknowledged” record is
written to alarm history.

7.7.1 Using 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 8.9.5), alarms can be viewed and acknowledged using ProLink II, a PROFIBUS host with the
EDD, or PROFIBUS bus parameters. Alarm acknowledgment is optional.

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.

Ignore alarms are never listed.

You can acknowledge alarms from the Alarm Log window.

In the Alarm Log window:

• The alarms are organized into two categories: High Priority and Low Priority. Each category is
displayed on a separate panel.

• On a panel, a green LED indicates “inactive but unacknowledged” and a red LED indicates
“active.”

Note: The location of alarms on the Alarm Log panels is pre-defined, and is not affected by alarm
severity.

and retrieve information from alarm history. See Table D-4.

To view the status of a group of preselected alarms, use Indices 10–17.

Acknowledge Alarm control to the alarm you want to acknowledge.

Acknowledge All Alarms control to Acknowledge.

Note: These are the same alarms that are displayed in the ProLink II Status window.

To view information about a single alarm:

1. Set Index 20 to the code of the alarm you want to check.

2. Read Index 22, and interpret the data using the following codes:

• 0x00 = Acknowledged and cleared

• 0x01 = Active and acknowledged

• 0x10 = Not acknowledged, but cleared

• 0x11 = Not acknowledged, and active

3. Other information about the indexed alarm is available in the following locations:

• Index 23: Number of times this alarm has become active

• Index 24: The time this alarm was last posted

7.8 Using 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 totalizers can be started and stopped, and the totals can be viewed and reset.

The inventories track the same values as the totalizers. Whenever totalizers are started or stopped, all
inventories (including the API volume inventory and enhanced density inventories) are started or

8.2 Configuring 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 want to use a gas volume flow unit,
additional configuration is required.

Note: If you will use the petroleum measurement application or the enhanced density application,
liquid volume flow measurement is required.

52 Micro Motion® Model 2400S Transmitters for PROFIBUS-DP

Optional Configuration

The method used to configure volume flow measurement for gas depends on the method you are
using: ProLink II, a PROFIBUS host with the EDD, or PROFIBUS bus parameters. In all cases, you
must:

• Enable gas standard volume flow

• Select the measurement unit to use

• Set the low flow cutoff value

• Specify the standard density (density at reference conditions) of your gas

Note: Using the display, you can only select a volume measurement unit from the set available for the

8.2.2 Using a PROFIBUS host with the EDD

To configure volume flow measurement for gas using a PROFIBUS host with the EDD:

1. Referring to Figure C-8:

a. Enable GSV.

b. Send the command to the transmitter.

c. Configure

Gas density value, GSV flow units, GSV total units, and GSV cutoff as

desired.

2. Send the command to the transmitter.

8.2.3 Using PROFIBUS bus parameters

To configure volume flow measurement for gas using PROFIBUS bus parameters:

1. Referring to the Measurement block (Table D-2):

a. Enable gas standard volume measurement (Index 33).

b. Set other gas measurement parameters as desired (Indices 34, 38, and 40).

2. Send the command to the transmitter.

8.3 Configuring cutoffs

Cutoffs are user-defined values below which the transmitter reports a value of zero for the specified
process variable. Cutoffs can be set for mass flow, volume flow, gas standard volume flow, and
density.

See Table 8-2 for cutoff default values and related information. See Section 8.3.1 for information on
how the cutoffs interact with other transmitter measurements.

To configure cutoffs:

• Using ProLink II, see Figure C-2.

• Using a PROFIBUS host with the EDD, see Figure C-8.

• Using PROFIBUS bus parameters, use the Measurement block (see Table D-2), Indices 18, 19,
20, and 40.

Note: This functionality cannot be configured via the display menus.

8.3.1 Cutoffs and volume flow

If liquid volume flow is enabled:

• 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 gas standard volume flow is enabled, neither the mass flow cutoff nor the density cutoff is applied
to the volume flow calculation.

8.4 Configuring 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 specify a new damping value, it 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.

To configure damping values:

• Using ProLink II, see Figure C-2.

• Using a PROFIBUS host with the EDD, see Figure C-8.

• Using PROFIBUS bus parameters, use the Measurement block (see Table D-2), Indices 12, 13,
and 14.

Note: This functionality cannot be configured via the display menus.

Configuration and Use Manual 55

Optional Configuration

Table 8-3 Valid damping values

Process variable Valid damping values

Flow (mass and volume) 0, 0.04, 0.08, 0.16, ... 40.96

Density 0, 0.04, 0.08, 0.16, ... 40.96

Temperature 0, 0.6, 1.2, 2.4, 4.8, ... 76.8

8.4.1 Damping 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.

8.5 Configuring 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.

Options for flow direction include:

• Forward only

•Reverse only

• Absolute value

• Bidirectional

• Negate/Forward only

• Negate/Bidirectional

For the effect of flow direction on flow totals and flow values, see Table 8-4.

To configure flow direction:

• Using ProLink II, see Figure C-2.

• Using a PROFIBUS host with the EDD, see Figure C-8.

• Using PROFIBUS bus parameters, use the Measurement block (see Table D-2), Index 21.

Note: This functionality cannot be configured via the display menus.

(3) Process fluid flowing in opposite direction from flow direction arrow on sensor.

8.6 Configuring 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.

8.6.1 Defining events

To define an event:

• Using ProLink II, see Figure C-3.

• Using a PROFIBUS host with the EDD, see Figure C-9.

• Using PROFIBUS bus parameters, use the Diagnostic block (see Table D-4).

The following general steps are required:

1. Select the event to define (Diagnostic block, Index 4).

2. Specify the Event Type (Diagnostic block, Index 5). Event Type options are defined in
Table 8-5.

3. Assign a process variable to the event (Diagnostic block, Index 8).

Configuration and Use Manual 57

Optional Configuration

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 (Diagnostic block, Index 6) is used.

• If Event Type is In Range or Out of Range, both Setpoint A (Diagnostic block, Index 6)

Note: If a mass or volume total has been assigned to Event 1 or Event 2 and also configured as a
display variable, if the event type is High or Low, and the transmitter is configured to allow resetting
totalizers from the display, you can use the display to define or change the high setpoint (Setpoint A).
See Section 7-3.

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

Note: For consistency with other Micro Motion products, the Discrete Input panel is used here even
though the Model 2400S DP transmitter does not provide a discrete input.

• Using the display, see Figure C-15 and use the ACT submenu.

• Using a PROFIBUS host with the EDD, see Figure C-10.

• Using PROFIBUS bus parameters, use Index 83 in the Diagnostic block (see Table D-4) to

• Discrete event process variable (Index 8) = 0

• Discrete event setpoint A (Index 6) = 2

• Discrete event setpoint B (Index 7) = 20

• Discrete event assignment (Index 83) = 57

• Discrete event action code (Index 82) = 9

8.6.2 Checking 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, and also in the Output Levels window.

• For PROFIBUS hosts using the EDD, event status is displayed in the Device menu (see
Figure C-6).

• Using PROFIBUS bus parameters, event status is reported in the Diagnostic block, Index 9
(see Table D-4).

Note: You cannot view event status using a PROFIBUS host with the GSD.

8.6.3 Changing event setpoints from the display

For Event 1 or Event 2 only, the value of Setpoint A can be changed from the display, under the
following circumstances:

• A mass total, volume total, petroleum measurement total, or enhanced density total must be
assigned to the event.

• The event type must be either High or Low.

• The assigned total must be configured as a display variable (see Section 8.9.3).

• The transmitter must be configured to allow resetting totalizers from the display (see
Section 8.9.5

Then, to change Setpoint A from the display:

3. Enter the new setpoint value. See Section 3.5.5 for instructions on entering floating-point
values with the display.

8.7 Configuring 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:

• Low slug flow 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/cm3.

• High slug flow 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/cm3.

• 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 appropriate

Required Configuration Optional ConfigurationUsing the TransmitterUsing a PROFIBUS Host Required Configuration Optional ConfigurationUsing the TransmitterUsing a PROFIBUS Host Required Configuration Optional ConfigurationUsing the TransmitterUsing a PROFIBUS Host Required Configuration Optional ConfigurationUsing the TransmitterUsing a PROFIBUS Host

0.0 g/cm3;

5.0 g/cm3;

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 rate 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 Manual 61

Optional Configuration

To configure slug flow parameters:

• Using ProLink II, see Figure C-2.

• Using a PROFIBUS host with the EDD, see Figure C-8.

• Using PROFIBUS bus parameters, use the Diagnostic block (see Table D-4), Indices 1, 2,
and 3.

Note: This functionality cannot be configured via the display menus.

Note: The slug flow limits must be entered in g/cm
density. Slug flow duration is entered in seconds. 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. If
slug flow duration is set to 0, the mass flow rate will be forced to 0 as soon as slug flow is detected.

8.8 Configuring status alarm severity

The 2400S DP transmitter can report faults in the following ways:

• Setting the “alarm active” status bit

• Writing an “alarm active” record to alarm history

• Implementing the digital communications fault action (see Section 8.10.7)

Status alarm severity determines which methods the transmitter will use when a specific alarm
condition occurs. See Table 8-8. (For a more extensive discussion of status alarm processing and
handling, see Section 7.7.)

The password can contain up to four numbers.

• If you are using the display to configure the display:

- You must enable Auto Scroll before you can configure Scroll Rate.

- You must enable the off-line password before you can configure the password.

8.10 Configuring digital communications

The digital communications parameters control how the transmitter will communicate using digital
communications. The following digital communications parameters can be configured:

• PROFIBUS-DP node address

• IrDA port usage

• Modbus address

• Modbus ASCII support

• Floating-point byte order

• Additional communications response delay

• Digital communications fault action

• Fault timeout

8.10.1 PROFIBUS-DP node address

The PROFIBUS-DP node address can be set with the address switches on the device (hardware
addressing mode) or with a PROFIBUS host.

Note: You cannot set the node address from ProLink II or the display.

The transmitter operates in either hardware addressing mode or software addressing mode:

• In hardware addressing mode, the address switches are set to a value between

0 and 126, and

the position of the address switches determines the actual node address. The software address
LED on the face of the transmitter is off (see Figure 3-1 or Figure 3-2).

• In software addressing mode, the address switches are set to

126 or greater, and the node

address is set via a Set Slave Address telegram from the host. The position of the address
switches does not necessarily match the actual node address. The software address LED is
either red or green:

- Red – the transmitter has not received a Set Slave Address telegram.

- Green – the transmitter has received a Set Slave Address telegram and recognized the

address.

The default node address for the Model 2400S DP transmitter is

126, which allows either hardware

addressing or software addressing.

68 Micro Motion® Model 2400S Transmitters for PROFIBUS-DP

Optional Configuration

To set the node address with address switches:

1. Remove the transmitter housing cover as described in Section 3.3.

2. Identify the three address switches on the user interface module of your transmitter (see
Figure 3-1 or Figure 3-2).

3. For each switch, insert a small blade into the slot to rotate the arrow to the desired position. For
example, to set the node address to

a. Rotate the arrow in the left switch to point to the digit

b. Rotate the arrow in the center switch to point to the digit

60:

0.

6.

c. Rotate the arrow in the right switch to point to the digit

0.

4. Power-cycle the transmitter. At this point, the new node address is recognized by the
transmitter, but not the host. You must update the host configuration for the new address.

To set the node address with software:

1. Ensure that the transmitter is in software addressing mode (software address LED is red or
green). If it is, skip this step and go to Step 2. If it is currently in hardware addressing mode
(software address LED is off):

a. Set the address switches to

126 or higher.

b. Power-cycle the transmitter. At this point, the transmitter enters software addressing mode,

and the software address LED is red.

2. Send a Set Slave Address telegram from the host. It is not necessary to power-cycle the
transmitter. At this point, the new node address is recognized by both the transmitter and the
host, and the software address LED is green.

To return the node address to

1. Because a Set Slave Address telegram cannot specify a node address of

126 (sometimes required for maintenance):

126, you must set this

address via the address switches. If the transmitter is currently in hardware addressing mode
(software address LED is off), skip this step and go to Step 2. If it is currently in software
addressing mode (software address LED is red or green), switch to hardware addressing mode
as follows:

a. Set the address switches to any value between

0 and 125 (e.g., 100).

b. Power-cycle the transmitter. The transmitter enters hardware addressing mode, and the

software address LED is off.

2. Set the address switches to

126.

3. Power-cycle the transmitter.

8.10.2 IrDA 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.

To enable or disable the IrDA port:

• Using ProLink II, see Figure C-2.

• Using the display menus, see Figure C-15.

• Using a PROFIBUS host with the EDD, see Figure C-10.

• Using PROFIBUS bus parameters, use the Local Display block (see Table D-6), Index 34.

Configuration and Use Manual 69

Optional Configuration

To configure the IrDA port for read-only or read/write access:

• Using ProLink II, see Figure C-2.

• Using the display menus, see Figure C-15.

• Using a PROFIBUS host with the EDD, see Figure C-10.

• Using PROFIBUS bus parameters, use the Local Display block (see Table D-6), Index 35.

8.10.3 Modbus 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 8.10.4). Valid Modbus addresses are as follows:

• Modbus ASCII enabled:

• Modbus ASCII disabled: 0–127

To configure the Modbus address:

• Using ProLink II, see Figure C-2.

1–15, 32–47, 64–79, 96–110

• Using the display, see Figure C-15.

Note: This functionality cannot be configured via PROFIBUS protocol.

8.10.4 Modbus ASCII support

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 C-2.

• Using the display, see Figure C-15.

Note: This functionality cannot be configured via PROFIBUS protocol.

8.10.5 Floating-point byte order

Note: This parameter affects only Modbus communications. PROFIBUS communications are not
changed.

Four bytes are used to transmit floating-point values. For contents of bytes, see Table 8-11.

2 E M M M M M M M E = Exponent

3 M M M M M M M M M = Mantissa

4 M M M M M M M M M = Mantissa

The default byte order for the Model 2400S transmitter is 3–4 1–2. You may need to reset byte order
to match the byte order used by a remote host or PLC.

To configure byte order using ProLink II, see Figure C-2.

Note: This functionality cannot be configured via the display menus or PROFIBUS protocol.

Some hosts or PLCs operate at slower speeds than the transmitter. In order to synchronize
communication with these devices, you can configure an additional time delay to be added to each
response the transmitter sends to the remote host.

The basic unit of delay is 2/3 of one character time, as calculated for the current serial port baud rate
setting and character transmission parameters. This basic delay unit is multiplied by the configured
value to arrive at the total additional time delay. You can specify a value in the range 1 to 255.

To configure additional communications response delay using ProLink II, see Figure C-2.

Note: This functionality cannot be configured via the display menus or PROFIBUS protocol.

8.10.7 Digital communications fault action

Note: This parameter affects both PROFIBUS and Modbus communications.

Digital communications fault action controls how process variables will be reported via digital
communications during 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.
See Section 7.7 for more information.

To configure digital communications fault action:

• Using ProLink II, see Figure C-2.

• Using a PROFIBUS host with the EDD, see Figure C-9.

• Using PROFIBUS bus parameters, use the Diagnostic block (see Table D-4), Index 18.

Note: This functionality cannot be configured via the display menus.

Note: Digital communications fault action is affected by the configured fault timeout. See
Section 8.10.8.

8.10.8 Fault timeout

By default, the transmitter activates the digital communications fault action as soon as the fault is
detected. The fault timeout (last measured value 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 reports the last measured value.

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 7.7. 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
Table 8-8.

8.13 Configuring sensor parameters

The sensor parameters are used to describe the sensor component of your flowmeter. One sensor
parameter (curved or straight tube) must be set during characterization (see Section 6.2). The
remaining sensor parameters are not used in transmitter processing, and are not required:

• Serial number

• Sensor material

• Liner material

•Flange

To configure sensor parameters:

• Using ProLink II, see Figure C-2.

• Using a PROFIBUS host with the EDD, see Figure C-10.

• Using PROFIBUS bus parameters, use the Device Information block (see Table D-5),
Indices 7–12.

Note: This functionality cannot be configured via the display menus.

8.14 Configuring the petroleum measurement application

The API parameters determine the values that will be used in API-related calculations. The API
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.

8.14.1 About 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 application enables Correction of Temperature on volume
of Liquids, or CTL.

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.

8.15 Configuring the enhanced density application

Micro Motion sensors provide direct measurements of density, but not of concentration. The enhanced
density application calculates enhanced density 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 enhanced density application, see the manual entitled
Micro Motion Enhanced Density Application: Theory, Configuration, and Use.

Note: The enhanced density application requires liquid volume measurement units. If you plan to use
enhanced density process variables, ensure that liquid volume flow measurement is specified. See
Section 8.2.

8.15.1 About the enhanced density application

The enhanced density calculation requires an enhanced density curve, which specifies the relationship
between temperature, concentration, and density for the process fluid being measured. Micro Motion
supplies a set of six standard enhanced density 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 enhanced density
process variables (see Table 8-17). The available enhanced density 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 enhanced density 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.

The transmitter can hold up to six curves at any given time, but only one curve can be active (used for
measurement) at a time. All curves that are in transmitter memory must use the same derived variable.

8.15.2 Configuration procedure

Complete configuration instructions for the enhanced density application are provided in the manual
entitled Micro Motion Enhanced Density Application: Theory, Configuration, and Use.

Note: The enhanced density manual uses ProLink II as the standard configuration tool for the
enhanced density application. Because the menu structure defined in the EDD is very similar to the
ProLink II menus, you can follow the instructions for ProLink II and adapt them to your host.

The typical configuration procedure simply sets up the enhanced density application to use a standard
curve. The following steps are required:

1. Set the transmitter’s density measurement unit to match the unit used by the curve (as listed in
Table 8-16).

2. Set the transmitter’s temperature measurement unit to match the unit used by the curve (as
listed in Table 8-16).

3. Set the derived variable to Mass Conc (Dens).

4. Specify the active curve.

To perform these steps:

• With ProLink II, see Figures C-2 and C-3.

• With a PROFIBUS host and the EDD, see Figures C-8 and C-11.

• With PROFIBUS bus parameters, use the Measurement block and the Enhanced Density block
(see Tables D-2 and D-8).

Pressure Compensation and External Temperature Compensation

9.1 Overview

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 procedures provided in this chapter assume that you have established communication with
the Model 2400S DP transmitter and that you are complying with all applicable safety requirements.

Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.

9.2 Pressure compensation

The Model 2400S DP 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.

Measurement Performance DefaultsTroubleshootingCompensation

9.2.1 Options

There are two ways to implement pressure compensation:

• You can use an output module to obtain pressure data from the system. See Section 9.4.

• If the operating pressure is a known static value, you can configure that value in the
transmitter.

Note: Ensure that your pressure value is accurate, or that your pressure measurement device is
accurate and reliable.

9.2.2 Pressure correction factors

When configuring pressure compensation, you must provide the flow calibration pressure – the
pressure at which the flowmeter was calibrated (which therefore defines the pressure at which there
will be no effect on the calibration factor). Refer to the calibration document shipped with your
sensor. If the data is unavailable, enter

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 flow factor is 0.000004 % per PSI, enter a pressure correction flow factor of
–0.000004 % per PSI).

9.3 External temperature compensation

External temperature compensation can be used with the petroleum measurement application or the
enhanced density application:

• If external temperature compensation is enabled, an external temperature value (or a static
temperature value), rather than the temperature value from the sensor, is used in petroleum
measurement or enhanced density calculations only. The temperature value from the sensor is
used for all other calculations.

• If external temperature compensation is disabled, the temperature value from the sensor is
used in all calculations.

There are two ways to implement external temperature compensation:

• You can use an output module to obtain temperature data from the system. See Section 9.4.

• If the operating temperature is a known static value, you can configure that value in the
transmitter.

Note: Ensure that your temperature value is accurate, or that your temperature measurement device is
accurate and reliable.

To enable and configure external temperature compensation:

Measurement Performance

10.1 Overview

This chapter describes the following procedures:

• Meter verification – see Section 10.3

• 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 procedures provided in this chapter assume that you have established communication with
the Model 2400S DP transmitter and that you are complying with all applicable safety requirements.

Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter.

10.2 Meter validation, meter verification, and calibration

The Model 2400S transmitter supports the following procedures for the evaluation and adjustment of
measurement performance:

• 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 DP transmitters. Meter verification
is available only if the 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.

Measurement Performance DefaultsTroubleshootingCompensation

10.2.1 Meter verification

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.

Note: Micro Motion recommends performing meter verification at regular intervals.

Configuration and Use Manual 87

Measurement Performance

There are two versions of the meter verification application: the original version and Micro Motion
Smart Meter Verification. Table 10-1 lists requirements for each version. Table 10-2 provides a
comparison of the two versions.

Note: If you are running an older version of ProLink II or the EDD, you will not be able to access the
additional features in Smart Meter Verification. If you are running an updated version of ProLink II
or the EDD with the original version of meter verification, the meter verification procedures will be
slightly different from the procedures shown here.

10.2.2 Meter 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.

Measurement Performance DefaultsTroubleshootingCompensation

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 & Measures standard.
You may need to calculate and adjust meter factors periodically to comply with regulations.

10.2.3 Calibration

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.

Configuration and Use Manual 89

Measurement Performance

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.

10.2.4 Comparison and recommendations

When choosing among 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.

- The original version of meter verification requires approximately three minutes to
perform. During these three minutes, flow can continue (provided sufficient stability is
maintained); however, measurement is halted.

- 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 with
low-temperature and high-temperature fluids. Zero calibration requires stopping flow
through the sensor.

• External measurement requirements

- Neither version of meter verification requires 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

- 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
factory zero (or, if using ProLink II, the previous 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 that you purchase the meter verification option and perform meter
verification frequently.

10.3 Performing meter verification

10.3.1 Preparing for the meter verification test

Process fluid and process conditions

The meter verification test 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, reduce or stop flow.

If stability varies outside test limits, the test will be aborted. Verify the stability of the process and
repeat the test.

Transmitter configuration

Meter verification is not affected by any parameters configured for flow, density, or temperature. It is
not necessary to change the transmitter configuration.

Measurement Performance DefaultsTroubleshootingCompensation

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 (Smart Meter Verification) or three minutes (original version). Disable all
control loops for the duration of the test, and ensure that any data reported during this period is
handled appropriately.

Specification uncertainty limit

The specification uncertainty limit defines the acceptable degree of variation from factory results,
expressed as a percentage. Variation inside the limit is reported as Pass. Variation outside the limit is
reported as Fail or Caution.

• In Smart Meter Verification, the specification uncertainty limit is set at the factory and cannot
be configured.

• In the original version of meter verification, the specification uncertainty limit is configurable.
However, Micro Motion suggests using the default value. Contact Micro Motion Customer
Service before changing the specification uncertainty limit.

10.3.2 Running the meter verification test, original version

To perform meter verification:

• Using ProLink II, follow the procedure illustrated in Figure 10-1.

• Using the display menu, follow the procedure illustrated in Figure 10-2. For a complete
illustration of the meter verification display menu, see Figure C-17.

• Using a PROFIBUS host with the EDD, refer to Figure C-7 and follow the procedure
illustrated in Figure 10-4.

• Using PROFIBUS bus parameters, use the Diagnostic block (see Table D-4) and follow the
procedure illustrated in Figure 10-4.

Note: If you start a meter verification test remotely, the transmitter display shows the following
