Topics covered in this chapter:
Power up the transmitter
•
Check meter status
•
Make a startup connection to the transmitter
•
(Optional) Adjust digital communications settings
•
Verify mass flow measurement
•
Verify the zero
•
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
Quick start
The Model 1500:
• Is DC powered only
• Has a minimum 19.2 to 28.8 VDC, 6.3 watts
• At startup, the transmitter power source must provide a minimum of 1.0 amperes of
short-term current per transmitter
• The length and conductor diameter of the power cable must be sized to provide
19.2 VDC minimum at the power terminals, at a load current of 330 mA
Procedure
1. Ensure that all transmitter and sensor covers and seals are closed.
WARNING!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.
2. Turn on the electrical power at the power supply.
The transmitter will automatically perform diagnostic routines. During this period,
Alert 009 is active. The diagnostic routines should complete in approximately
30 seconds. The status LED will turn green when the startup diagnostics are
complete. If the status LED exhibits different behavior, an alert is active.
Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics
can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial
startup, or if power has been off long enough to allow components to reach ambient
Configuration and Use Manual 5
Page 12
Quick start
temperature, allow the electronics to warm up for approximately 10 minutes before
relying on process measurements. During this warm-up period, you may observe minor
measurement instability or inaccuracy.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect
measurement accuracy.
1. Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and
checks for error conditions. During the power-up sequence, Alert A009 is active.
This alert should clear automatically when the power-up sequence is complete.
2. Check the status LED on the transmitter.

ment error (outputs continue to report process data)
Solid red High-severity alarm Alarm condition that will cause measurement
error (outputs in fault)
2.3 Make a startup connection to the transmitter
To configure the transmitter, you must have an active connection from a communications
tool. Follow this procedure to make your first connection to the transmitter.
Identify the connection type to use, and follow the instructions for that connection type in
the appropriate appendix. Use the default communications parameters shown in the
appendix.

1. To change the communications parameters using ProLink III, choose Device Tools >
Configuration > Communications.
2. To change the communications parameters using the Field Communicator, choose
On-Line Menu > Configure > Manual Setup > Inputs/Outputs > Communications.
Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use
any available method.
• Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in
the Process Variables panel.
• Connect to the transmitter with the Field Communicator and read the value for Mass
Flow Rate.
On-Line Menu > Overview > Primary Purpose Variables
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.
• Review the troubleshooting suggestions for flow measurement issues.

Configuration and Use Manual 7
Verify the zero
Verifying the zero helps you determine if the stored zero value is appropriate to your
installation, or if a field zero can improve measurement accuracy.
Page 14
Quick start
The zero verification procedure analyzes the Live Zero value under conditions of zero flow,
and compares it to the Zero Stability range for the sensor. If the average Live Zero value is
within a reasonable range, the zero value stored in the transmitter is valid. Performing a
field calibration will not improve measurement accuracy.
Important
In most cases, the factory zero is more accurate than the field zero. Do not zero the meter unless one
of the following is true:
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Procedure
1. Allow the flowmeter to warm up for at least 20 minutes after applying power.
2. Run the process fluid through the sensor until the sensor temperature reaches the
normal process operating temperature.
3. Stop flow through the sensor by shutting the downstream valve, and then the
upstream valve if available.
4. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
5. From ProLink III, choose Device Tools > Calibration > Zero Verification and
Calibration > Verify Zero and wait until the procedure completes.
6. Observe the drive gain, temperature, and density readings. If they are stable, check
the Live Zero or Field Verification Zero value. If the average value is close to 0, you
should not need to zero the meter.
7. If the zero verification procedure fails:
a. Confirm that the sensor is completely blocked in, that flow has stopped, and that
the sensor is completely full of process fluid.
b. Verify that the process fluid is not flashing or condensing, and that it does not
contain particles that can settle out.
c. Remove or reduce sources of electromechanical noise if appropriate.
d. Repeat the zero verification procedure.
e. If it fails again, zero the meter.
Postrequisites
Restore normal flow through the sensor by opening the valves.

2.6.1 Terminology used with zero verification and zero calibration
Term Definition
Zero In general, the offset required to synchronize the left pickoff and the right
pickoff under conditions of zero flow. Unit = microseconds.
Factory Zero The zero value obtained at the factory, under laboratory conditions.
Field Zero The zero value obtained by performing a zero calibration outside the fac-
tory.
Prior Zero The zero value stored in the transmitter at the time a field zero calibration
is begun. May be the factory zero or a previous field zero.
Manual Zero The zero value stored in the transmitter, typically obtained from a zero
calibration procedure. It may also be configured manually. Also called
“mechanical zero” or “stored zero”.
Live Zero The real-time bidirectional mass flow rate with no flow damping or mass
flow cutoff applied. An adaptive damping value is applied only when the
mass flow rate changes dramatically over a very short interval. Unit = configured mass flow measurement unit.
Zero Stability A laboratory-derived value used to calculate the expected accuracy for a
sensor. Under laboratory conditions at zero flow, the average flow rate is
expected to fall within the range defined by the Zero Stability value (0 ±
Zero Stability). Each sensor size and model has a unique Zero Stability value. Statistically, 95% of all data points should fall within the range defined
by the Zero Stability value.
Zero Calibration The procedure used to determine the zero value.
Zero Time The time period over which the Zero Calibration procedure is performed.
Unit = seconds.
Field Verification Zero A 3-minute running average of the Live Zero value, calculated by the
transmitter. Unit = configured mass flow measurement unit.
Zero Verification A procedure used to evaluate the stored zero and determine whether or
not a field zero can improve measurement accuracy.

Tip
Write-protecting the transmitter prevents accidental changes to configuration. It does not prevent
normal operational use. You can always disable write-protection, perform any required configuration
changes, then re-enable write-protection.
Restore the factory configuration
ProLink III Device Tools > Configuration Transfer > Restore Factory Configuration
Field Communicator Service Tools > Maintenance > Reset/Restore > Restore Factory Configuration
Overview
Restoring the factory configuration returns the transmitter to a known operational
configuration. This may be useful if you experience problems during configuration.
Important
You cannot restore factory configurations with a 700 core.
Tip
Restoring the factory configuration is not a common action. You may want to contact customer
support to see if there is a preferred method to resolve any issues.

Overview
A special measurement unit is a user-defined unit of measure that allows you to report
process data, totalizer data, and inventory data in a unit that is not available in the
transmitter. A special measurement unit is calculated from an existing measurement unit
using a conversion factor.
Procedure
1. Specify Base Mass Unit.
Base Mass Unit is the existing mass unit that the special unit will be based on.

2. Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
3. Calculate Mass Flow Conversion Factor as follows:
a. x base units = y special units
b. Mass Flow Conversion Factor = x ÷ y
The original mass flow rate value is divided by this value.
4. Enter Mass Flow Conversion Factor.
5. Set Mass Flow Label to the name you want to use for the mass flow unit.
6. Set Mass Total Label to the name you want to use for the mass total and mass
inventory unit.
The special measurement unit is stored in the transmitter. You can configure the
transmitter to use the special measurement unit at any time.
Example: Defining a special measurement unit for mass flow
You want to measure mass flow in ounces per second (oz/sec).
4.1.2
1. Set Base Mass Unit to Pounds (lb).
2. Set Base Time Unit to Seconds (sec).
3. Calculate Mass Flow Conversion Factor:
a. 1 lb/sec = 16 oz/sec
b. Mass Flow Conversion Factor = 1 ÷ 16 = 0.0625
4. Set Mass Flow Conversion Factor to 0.0625.
5. Set Mass Flow Label to oz/sec.
6. Set Mass Total Label to oz.
Configure Flow Damping
ProLink III Device Tools > Configuration > Process Measurement > Flow
Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Damping
Overview
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
Procedure
Set Flow Damping to the value you want to use.
Configuration and Use Manual 19
Page 26
Configure process measurement
The default value is 0.8 seconds. The range depends on the core processor type and the
setting of Update Rate, as shown in the following table.
Update Rate setting Damping range
Normal
Special
The value you enter is automatically rounded off to the nearest valid value. For example, if
the damping is currently set to 0.8 seconds, any value entered up to 1.2 seconds will be
rounded down to 0.8 seconds, and any value entered from 1.21 to 1.59 seconds will be
rounded up to 1.6 seconds.

Effect of flow damping on volume measurement
Flow damping affects volume measurement for liquid volume data. Flow damping also
affects volume measurement for gas standard volume data. The transmitter calculates
volume data from the damped mass flow data.
Interaction between Flow Damping and mA Output Damping
In some circumstances, both Flow Damping and mA Output Damping are applied to the
reported mass flow value.
Flow Damping controls the rate of change in flow process variables. mA Output Damping
controls the rate of change reported via the mA Output. If mA Output Process Variable is
set to Mass Flow Rate, and both Flow Damping and mA Output Damping are set to non-zero
values, flow damping is applied first, and the added damping calculation is applied to the
result of the first calculation.

Configure Mass Flow Cutoff
ProLink III Device Tools > Configuration > Process Measurement > Flow
Field Communicator Configure > Manual Setup > Measurements > Flow > Mass Flow Cutoff
Page 27
Configure process measurement
Overview
Mass Flow Cutoff specifies the lowest mass flow rate that will be reported as measured. All
mass flow rates below this cutoff will be reported as 0.
Procedure
Set Mass Flow Cutoff to the value you want to use.
The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the
factory. The recommended value is 0.5% of the nominal flow rate of the attached sensor.
See the sensor specifications. Leaving Mass Flow Cutoff at 0.0 g/sec is not recommended.
Effect of Mass Flow Cutoff on volume measurement
Mass Flow Cutoff does not affect volume measurement. Volume data is calculated from
the actual mass data rather than the reported value.
Volume flow has a separate Volume Flow Cutoff that is not affected by the Mass Flow
Cutoff value.
Interaction between Mass Flow Cutoff and mA Output Cutoff
Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as
measured. mA Output Cutoff defines the lowest flow rate that will be reported via the mA
output. If mA Output Process Variable is set to Mass Flow Rate, the mass flow rate reported
via the mA Output is controlled by the higher of the two cutoff values.
Mass Flow Cutoff affects all reported values and values used in other transmitter behavior
(e.g., events defined on mass flow).
mA Output Cutoff affects only mass flow values reported via the mA Output.
Example: Cutoff interaction with mA Output Cutoff lower than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 10 g/sec
• Mass Flow Cutoff: 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, mass flow will be reported as 0, and 0
will be used in all internal processing.
Example: Cutoff interaction with mA Output Cutoff higher than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 15 g/sec
Configuration and Use Manual 21
Page 28
Configure process measurement
• Mass Flow Cutoff: 10 g/sec
Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
- The mA Output will report zero flow.
- The Frequency Output will report the actual flow rate, and the actual flow rate
will be used in all internal processing.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0
will be used in all internal processing.
4.2 Configure volume flow measurement for liquid applications
The volume flow measurement parameters control how liquid volume flow is measured
and reported.
Restriction
You cannot implement both liquid volume flow and gas standard volume flow at the same time.

Effect of Flow Direction on mA Outputs
Flow Direction affects how the transmitter reports flow values via the mA Outputs. The mA
Outputs are affected by Flow Direction only if mA Output Process Variable is set to a flow
variable.
Flow Direction and mA Outputs
The effect of Flow Direction on the mA Outputs depends on Lower Range Value configured
for the mA Output:
• If Lower Range Value is set to 0, see Figure 4‐1.
• If Lower Range Value is set to a negative value, see Figure 4‐2.

Overview
The two-phase flow parameters control how the transmitter detects and reports twophase flow (gas in a liquid process or liquid in a gas process).
Note
Two-phase flow is also referred to as slug flow.
Configuration and Use Manual 39
Page 46
Configure process measurement
Procedure
1. Set Two-Phase Flow Low Limit to the lowest density value that is considered normal
2. Set Two-Phase Flow High Limit to the highest density value that is considered
in your process.
Values below this will cause the transmitter to post Alert A105 (Two-Phase Flow).
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the
occurrence of two-phase flow alerts that are not significant to your process, set Two-Phase
Flow Low Limit slightly below your expected lowest process density.
You must enter Two-Phase Flow Low Limit in g/cm³, even if you configured another
unit for density measurement.
The default value for Two-Phase Flow Low Limit is 0.0 g/cm³. The range is 0.0 to
10.0 g/cm³.
normal in your process.
Micro Motion recommends leaving Two-Phase Flow High Limit at the default value.
Values above this will cause the transmitter to post Alert A105 (Two-Phase Flow).
You must enter Two-Phase Flow High Limit in g/cm³, even if you configured another
unit for density measurement.
The default value for Two-Phase Flow High Limit is 5.0 g/cm³. The range is 0.0 to
10.0 g/cm³.
3. Set Two-Phase Flow Timeout to the number of seconds that the transmitter will wait
for a two-phase flow condition to clear before posting the alert.
The default value for Two-Phase Flow Timeout is 0.0 seconds, meaning that the alert
will be posted immediately. The range is 0.0 to 60.0 seconds.
Detecting and reporting two-phase flow
Two-phase flow (gas in a liquid process or liquid in a gas process) can cause a variety of
process control issues. By configuring the two-phase flow parameters appropriately for
your application, you can detect process conditions that require correction.
Micro Motion recommends leaving Two-Phase Flow High Limit at the default value.
A two-phase flow condition occurs whenever the measured density goes below Two-Phase
Flow Low Limit or above Two-Phase Flow High Limit. If this occurs:
• A two-phase flow alert is posted to the active alert log.
• All outputs that are configured to represent flow rate hold their last pre‐alert value
for the number of seconds configured in Two-Phase Flow Timeout.
If the two-phase flow condition clears before Two-Phase Flow Timeout expires:
• Outputs that represent flow rate revert to reporting actual flow.
40 Micro Motion Model 1500 Transmitters with Analog Outputs
Page 47
• The two-phase flow alert is deactivated, but remains in the active alert log until it is
acknowledged.
If the two-phase flow condition does not clear before Two-Phase Flow Timeout expires, the
outputs that represent flow rate report a flow rate of 0.
If Two-Phase Flow Timeout is set to 0.0 seconds, the outputs that represent flow rate will
report a flow rate of 0 as soon as two-phase flow is detected.
4.5.3 Configure Density Damping
ProLink III Device Tools > Configuration > Process Measurement > Density
Field Communicator Configure > Manual Setup > Measurements > Density > Density Damping
Overview
Density Damping controls the amount of damping that will be applied to the line density
value.
Configure process measurement
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
Tip
Density damping affects all process variables that are calculated from line density.
Procedure
Set Density Damping to the value you want to use.
The default value is 1.6 seconds. The range depends on the core processor type and the
setting of Update Rate, as shown in the following table:
Update Rate setting
Normal
Special
Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value
changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
Damping range
0 to 51.2 seconds
0 to 40.96 seconds
Configuration and Use Manual 41
Page 48
Configure process measurement
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
The value you enter is automatically rounded off to the nearest valid value. The valid values
for Density Damping depend on the setting of Update Rate.

Effect of Density Damping on volume measurement
Density Damping affects liquid volume measurement. Liquid volume values are calculated
from the damped density value rather than the measured density value. Density Damping
does not affect gas standard volume measurement.

4.5.4
Interaction between Density Damping and Added Damping
When the mA Output is configured to report density, both Density Damping and Added
Damping are applied to the reported density value.
Density Damping controls the rate of change in the value of the process variable in
transmitter memory. Added Damping controls the rate of change reported via the mA
Output.
If mA Output Process Variable is set to Density, and both Density Damping and Added
Damping are set to non-zero values, density damping is applied first, and the added
damping calculation is applied to the result of the first calculation. This value is reported
over the mA Output.
Configure Density Cutoff
Density Cutoff specifies the lowest density value that will be reported as measured. All
density values below this cutoff will be reported as 0.
Procedure
Set Density Cutoff to the value you want to use.
For most applications, the default setting (0.2 g/cm³) is sufficient. The range is 0.0 g/cm³
to 0.5 g/cm³.
Effect of Density Cutoff on volume measurement
Density Cutoff affects liquid volume measurement. If the density value goes below Density
Cutoff, the volume flow rate is reported as 0. Density Cutoff does not affect gas standard
volume measurement. Gas standard volume values are always calculated from the value
configured for Standard Gas Density or polled value if configured for polled base density.

Tip
Temperature Damping affects all process variables, compensations, and corrections that use
temperature data from the sensor.
Procedure
Enter the value you want to use for Temperature Damping.
The default value is 4.8 seconds. The range is 0.0 to 38.4 seconds.
Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value
changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual

Effect of Temperature Damping on process measurement
Temperature Damping affects all processes and algorithms that use temperature data
from the internal sensor RTD.
Temperature compensation
Temperature compensation adjusts process measurement to compensate for the effect of
temperature on the sensor tubes.
Configure pressure compensation
Pressure compensation adjusts process measurement to compensate for the pressure
effect on the sensor. The pressure effect is the change in the sensor’s sensitivity to flow
and density caused by the difference between the calibration pressure and the process
pressure.

5.1 Configure response time parameters
You can configure the rate at which process data is polled and process variables are
calculated.
5.1.1 Configure Update Rate
ProLink III Device Tools > Configuration > Process Measurement > Response > Update Rate
Field Communicator Configure > Manual Setup > Measurements > Update Rate
Overview
Update Rate controls the rate at which process data is polled and process variables are
calculated. Update Rate = Special produces faster and “noisier” response to changes in the
process. Do not use Special mode unless required by your application.
Tip
For systems with a standard core processor, Special mode can improve performance for applications
with entrained air or Empty-Full-Empty conditions. This does not apply to systems with an enhanced
core processor.
Prerequisites
Before setting Update Rate to Special:
• Check the effects of Special mode on specific process variables.
• Contact customer support.
Procedure
1. Set Update Rate as desired.
Configuration and Use Manual 49
Page 56
Configure device options and preferences
Option Description
Normal
Special
If you change Update Rate, the settings for Flow Damping, Density Damping, and
Temperature Damping are automatically adjusted.
2. If you set Update Rate to Special, select the process variable to be polled at 100 Hz.
Effects of Update Rate = Special
All process data is polled at the rate of 20 times per second (20 Hz).
All process variables are calculated at 20 Hz.
This option is appropriate for most applications.
A single, user-specified process variable is polled at the rate of 100 times per second (100 Hz). Other process data is polled at 6.25 Hz. Some process, diagnostic,
and calibration data is not polled.
All available process variables are calculated at 100 Hz.
Use this option only if required by your application.
Incompatible features and functions
Special mode is not compatible with the following features and functions:
• Enhanced events. Use basic events instead.
• All calibration procedures.
• Zero verification.
• Restoring the factory zero or the prior zero.
If required, you can switch to Normal mode, perform the desired procedures, and then
return to Special mode.
Process variable updates
Some process variables are not updated when Special mode is enabled.

A008, A016, A017, A033. For all other alerts, fault actions are performed as soon as the alert is
detected.
Procedure
Set Fault Timeout as desired.
The default value is 0 seconds. The range is 0 to 60 seconds.
If you set Fault Timeout to 0, fault actions are performed as soon as the alert condition is
detected.
The fault timeout period begins when the transmitter detects an alert condition. During
the fault timeout period, the transmitter continues to report its last valid measurements.
If the fault timeout period expires while the alert is still active, the fault actions are
performed. If the alert condition clears before the fault timeout expires, no fault actions
are performed.

6.1 Configure the transmitter channels
ProLink III Device Tools > Configuration > I/O > Outputs
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channels > Channel C
Overview
You can configure Channel C on your transmitter to operate as a Frequency Output or a
Discrete Output. The channel configuration must match the wiring at the transmitter
terminals.
Prerequisites
To avoid causing process errors:
• Configure the channels before configuring the outputs.
• Before changing the channel configuration, ensure that all control loops affected by
the channel are under manual control.
Procedure
Set Channel C as desired.
Option
Frequency Output Channel C will operate as a Frequency Output.
Discrete Output Channel C will operate as a Discrete Output.
Description
Configuration and Use Manual 61
Page 68
Integrate the meter with the control system
Postrequisites
For each channel that you configured, perform or verify the corresponding input or output
configuration. When the configuration of a channel is changed, the channel’s behavior will
be controlled by the configuration that is stored for the selected input or output type, and
the stored configuration may not be appropriate for your process.
After verifying channel and output configuration, return the control loop to automatic
control.
6.2 Configure the mA Output
The mA Output is used to report the configured process variable. The mA Output
parameters control how the process variable is reported.
Your transmitter has one mA Output: Channel A.
Restriction
The process variable assigned to the primary mA Output is automatically assigned to the Frequency
Output. You cannot assign a different process variable.
6.2.1
Important
Whenever you change an mA Output parameter, verify all other mA Output parameters before
returning the meter to service. In some situations, the transmitter automatically loads a set of stored
values, and these values may not be appropriate for your application.
Configure mA Output Process Variable
ProLink III Device Tools > Configuration > I/O > Outputs > mA Output
Field Communicator Configure > Manual Setup > Inputs/Outputs > mA Output > Primary Variable
Overview
Use mA Output Process Variable to select the variable that is reported over the mA Output.
This variable is applied automatically to the Frequency Output.
Prerequisites
• If you plan to configure the output to report volume flow, ensure that you have set
Volume Flow Type as desired: Liquid or Gas Standard Volume.
• If you are using the HART variables, be aware that changing the configuration of mA
Output Process Variable will change the configuration of the HART Primary Variable
(PV) and the HART Tertiary Variable (TV).
Procedure
Set mA Output Process Variable as desired.
62 Micro Motion Model 1500 Transmitters with Analog Outputs

Integrate the meter with the control system
The default setting is Mass Flow Rate.
Postrequisites
If you changed the setting of mA Output Process Variable, verify the settings of Lower
Range Value (LRV) and Upper Range Value (URV).
Options for mA Output Process Variable
The transmitter provides a basic set of options for mA Output Process Variable, plus
several application-specific options. Different communications tools may use different
labels for the options.

URV
Overview
The Lower Range Value (LRV) and Upper Range Value (URV) are used to scale the mA
Output, that is, to define the relationship between mA Output Process Variable and the
mA Output level.
Prerequisites
Ensure that mA Output Process Variable is set to the desired process variable. Each process
variable has its own set of LRV and URV values. When you change the values of LRV and
URV, you are configuring values for the currently assigned mA Output process variable.
Ensure that the measurement unit for the configured process variable has been set as
desired.
Procedure
Set LRV and URV as desired.
• LRVis the value of mA Output Process Variable represented by an output of 4 mA. The
default value for LRV depends on the setting of mA Output Process Variable. Enter LRV
in the measurement units that are configured for mA Output Process Variable.
• URV is the value of mA Output Process Variable represented by an output of 20 mA.
The default value for URV depends on the setting of mA Output Process Variable. Enter
URV in the measurement units that are configured for mA Output Process Variable.
Tip
For best performance:
• Set LRV ≥ LSL (lower sensor limit).
• Set URV ≤ USL (upper sensor limit).
• Set these values so that the difference between URV and LRV is ≥ Min Span (minimum span).
Defining URV and LRV within the recommended values for Min Span, LSL, and USL ensures that the
resolution of the mA Output signal is within the range of the bit precision of the D/A converter.
64 Micro Motion Model 1500 Transmitters with Analog Outputs
Page 71
Integrate the meter with the control system
The mA Output uses a range of 4–20 mA to represent mA Output Process Variable.
Between LRV and URV, the mA Output is linear with the process variable. If the process
variable drops below LRV or rises above URV, the transmitter posts an output saturation
alert.
Default values for Lower Range Value (LRV) and Upper Range Value (URV)
Each option for mA Output Process Variable has its own LRV and URV. If you change the
configuration of mA Output Process Variable, the corresponding LRV and URV are loaded
and used.
Default values for Lower Range Value (LRV) and Upper Range Value (URV)Table 6-3:

6.2.3 Configure AO Cutoff
ProLink III Device Tools > Configuration > I/O > Outputs > mA Output
Field Communicator Configure > Manual Setup > Inputs/Outputs > mA Output > mA Output Settings > PV
MAO Cutoff
AO Cutoff (Analog Output Cutoff) specifies the lowest mass flow rate, volume flow rate, or
gas standard volume flow rate that will be reported through the mA Output. Any flow rates
below AO Cutoff will be reported as 0.
Restriction
AO Cutoff is applied only if mA Output Process Variable is set to Mass Flow Rate, Volume Flow Rate, or
Gas Standard Volume Flow Rate. If mA Output Process Variable is set to a different process variable, AO
Cutoff is not configurable, and the transmitter does not implement the AO cutoff function.
Procedure
Set AO Cutoff as desired.
The default value for AO Cutoff is 0.0 g/sec.
Tip
For most applications, the default value of AO Cutoff should be used. Contact customer service
before changing AO Cutoff.
Configuration and Use Manual 65
Page 72
Integrate the meter with the control system
Interaction between AO Cutoff and process variable cutoffs
When mA Output Process Variable is set to a flow variable (for example, mass flow rate or
volume flow rate), AO Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The
transmitter puts the cutoff into effect at the highest flow rate at which a cutoff is
applicable.
Example: Cutoff interaction
Configuration:
• mA Output Process Variable = Mass Flow Rate
• Frequency Output Process Variable = Mass Flow Rate
• AO Cutoff = 10 g/sec
• Mass Flow Cutoff = 15 g/sec
Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will
report zero flow.
Example: Cutoff interaction
6.2.4
Configuration:
• mA Output Process Variable = Mass Flow Rate
• Frequency Output Process Variable = Mass Flow Rate
• AO Cutoff = 15 g/sec
• Mass Flow Cutoff = 10 g/sec
Result:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
- The mA Output will report zero flow.
- The Frequency Output will report the actual flow rate.
• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.
Configure Added Damping
ProLink III Device Tools > Configuration > I/O > Outputs > mA Output
Field Communicator Configure > Manual Setup > Inputs/Outputs > mA Output > mA Output Settings > PV
Added Damping
Overview
Added Damping controls the amount of damping that will be applied to the mA Output.
66 Micro Motion Model 1500 Transmitters with Analog Outputs
Page 73
Integrate the meter with the control system
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
Added Damping affects the reporting of mA Output Process Variable through the mA
Output only. It does not affect the reporting of that process variable via any other method
(e.g., a Frequency Output or digital communications), or the value of the process variable
used in calculations.
Note
Added Damping is not applied if the mA Output is fixed (for example, during loop testing) or if the
mA Output is reporting a fault. Added Damping is applied while sensor simulation is active.
Procedure
Set Added Damping to the desired value.
The default value is 0.0 seconds. The range is 0.0 to 440 seconds.
When you specify a value for Added Damping, the transmitter automatically rounds the
value down to the nearest valid value.
Note
Added Damping values are affected by the setting of Update Rate and 100 Hz Variable.
Valid values for Added Damping Table 6-4:

Interaction between mA Output Damping and process variable damping
When mA Output Source is set to a flow rate variable, mA Output Damping interacts with
Flow Damping. If multiple damping parameters are applicable, the effect of damping the
process variable is calculated first, and the mA output damping calculation is applied to
the result of that calculation.

Result: A change in the mass flow rate will be reflected in the mA Output over a time
period that is greater than 3 seconds. The exact time period is calculated by the
transmitter according to internal algorithms which are not configurable.
6.2.5 Configure mA Output Fault Action and mA Output Fault Level
ProLink III Device Tools > Configuration > Fault Processing
Field Communicator Configure > Manual Setup > Inputs/Outputs > mA Output > mA Fault Settings
Overview
mA Output Fault Action controls the behavior of the mA Output if the transmitter
encounters an internal fault condition.
Note
For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement
the fault action until the timeout has elapsed.
Procedure
1. Set mA Output Fault Action to the desired value.
The default setting is Downscale.
Restriction
If Digital Communications Fault Action is set to NAN (not a number), you cannot set mA
Output Fault Action or Frequency Output Fault Action to None. If you try to do this, the
transmitter will not accept the configuration.
2. If you set mA Output Fault Action to Upscale or Downscale, set mA Output Fault Level
as desired.

6.3 Configure the Frequency Output
The Frequency Output is used to report a process variable. The Frequency Output
parameters control how the process variable is reported. Your transmitter has one
Frequency Output: Channel C.
Restriction
The process variable assigned to the primary mA Output is automatically assigned to the Frequency
Output. You cannot assign a different process variable.

Option Description
Frequency=Flow (default) Frequency calculated from flow rate

A user-specified number of pulses represents one flow unit
A pulse represents a user-specified number of flow units
2. Set additional required parameters.
• If you set Frequency Output Scaling Method to Frequency=Flow, set Rate Factor
and Frequency Factor.
• If you set Frequency Output Scaling Method to Pulses/Unit, define the number of
pulses that will represent one flow unit.
• If you set Frequency Output Scaling Method to Units/Pulse, define the number of
units that each pulse will indicate.
For all scaling methods, the transmitter puts out a fixed number of pulses per unit,
and at the same time, the Frequency Output signal varies in proportion to flowrate.
Calculate frequency from flow rate
The Frequency=Flow option is used to customize the Frequency Output for your application
when you do not know appropriate values for Units/Pulse or Pulses/Unit.
If you specify Frequency=Flow, you must provide values for Rate Factor and Frequency
Factor:
Rate Factor
Frequency

The maximum flow rate that you want the Frequency Output to report.
A value calculated as follows:
FrequencyFactor = x N
RateFactor
T
where:
T
Factor to convert selected time base to seconds
N
Number of pulses per flow unit, as configured in the receiving
device
The resulting Frequency Factor must be within the range of the Frequency Output ( :
• If Frequency Factor is less than1 Hz, reconfigure the receiving device for a higher
pulses/unit setting.
• If Frequency Factor is greater than 10,000 Hz, reconfigure the receiving device for a
lower pulses/unit setting.

transmitter encounters an internal fault condition.
Note
For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement
the fault action until the timeout has elapsed.
Procedure
1. Set Frequency Output Fault Action as desired.
The default value is Downscale (0 Hz).
2. If you set Frequency Output Fault Action to Upscale, set Frequency Fault Level to the
desired value.
The default value is 15000 Hz. The range is 10 to 15000 Hz.

CAUTION!
If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set
Digital Communications Fault Action to None. If you do not, the output will not report actual
process data, and this may result in measurement errors or unintended consequences for your
process.
Restriction
If Digital Communications Fault Action is set to NAN (not a number), you cannot set mA Output Fault
Action or Frequency Output Fault Action to None. If you try to do this, the transmitter will not accept
the configuration.
6.4 Configure the Discrete Output
The Discrete Output is used to report specific meter or process conditions. The Discrete
Output parameters control which condition is reported and how it is reported.
Restriction
Before you can configure the Discrete Output, you must configure a channel to operate as a Discrete
Output.
6.4.1
Important
Whenever you change a Discrete Output parameter, verify all other Discrete Output parameters
before returning the meter to service. In some situations, the transmitter automatically loads a set of
stored values, and these values may not be appropriate for your application.

Overview
Flow Switch is used to indicate that the flow rate (measured by the configured flow variable)
has moved past the configured setpoint, in either direction. The flow switch is
implemented with a user-configurable hysteresis.
Procedure
1. Set Discrete Output Source to Flow Switch, if you have not already done so.
2. Set Flow Switch Variable to the flow variable that you want to use to control the flow
switch.
3. Set Flow Switch Setpoint to the value at which the flow switch will be triggered
(after Hysteresis is applied).
• If the flow rate is below this value, the Discrete Output is ON.
• If the flow rate is above this value, the Discrete Output is OFF.
4. Set Hysteresis to the percentage of variation above and below the setpoint that will
operate as a deadband.
Hysteresis defines a range around the setpoint within which the flow switch will not
change. The default is 5%. The valid range is 0.1% to 10%.
6.4.2
Example: If Flow Switch Setpoint = 100 g/sec and Hysteresis = 5%, and the first
measured flow rate is above 100 g/sec, the Discrete Output is OFF. It will remain OFF
unless the flow rate drops below 95 g/sec. If this happens, the Discrete Output will
turn ON, and remain ON until the flow rate rises above 105 g/sec. At this point it
turns OFF and will remain OFF until the flow rate drops below 95 g/sec.
Configure Discrete Output Polarity
ProLink III Device Tools > Configuration > I/O > Outputs > Discrete Output

Overview
Discrete Outputs have two states: ON (active) and OFF (inactive). Two different voltage
levels are used to represent these states. Discrete Output Polarity controls which voltage
level represents which state.

6.5 Configure events
An event occurs when the real-time value of a user-specified process variable moves past a
user-defined setpoint. Events are used to provide notification of process changes or to
perform specific transmitter actions if a process change occurs.
Your transmitter supports two event models:
• Basic event model
• Enhanced event model
6.5.1
Configure a basic event
ProLink III Device Tools > Configuration > Events > Basic Events
Field Communicator Not available
Overview
A basic event is used to provide notification of process changes. A basic event occurs (is
ON) if the real-time value of a user-specified process variable moves above (HI) or below
(LO) a user-defined setpoint. You can define up to two basic events. Event status can be
queried via digital communications, and a Discrete Output can be configured to report
event status.
Procedure
1. Select the event that you want to configure.

Overview
An enhanced event is used to provide notification of process changes and, optionally, to
perform specific transmitter actions if the event occurs. An enhanced event occurs (is ON)
if the real-time value of a user-specified process variable moves above (HI) or below (LO) a
user-defined setpoint, or in range (IN) or out of range (OUT) with respect to two userdefined setpoints. You can define up to five enhanced events.

6.6 Configure digital communications
The digital communications parameters control how the transmitter will communicate
using digital communications.
Your transmitter supports the following types of digital communications:
• HART/Bell 202 over the primary mA terminals
• Modbus/RS-485 over the RS-485 terminals
• Modbus RTU via the service port
The Model 1500 has only a single Modbus port.
Procedure
You have the following digital communication options:
• During the first 10 seconds after a power cycle, connect to the service port using
address 111 and the service port communication parameters.
• After the initial startup period, you can connect using Modbus with the configured
Modbus address and communication parameters.

Procedure
1. Set HART Address to a value that is unique on your network.
• Default: 0
• Range: 0 to 15
Tips
• The default address is typically used unless you are in a multidrop environment.
• Devices using HART protocol to communicate with the transmitter may use either HART
Address or HART Tag (Software Tag) to identify the transmitter. Configure either or both,
as required by your other HART devices.
2. Ensure that mA Output Action is configured appropriately.
Option
Enabled (Live)
Disabled (Fixed)
Important
If you use ProLink III to set HART Address to 0, the program automatically enables mA Output
Action. If you use ProLink III to set HART Address to any other value, the program
automatically disables mA Output Action. This is designed to make it easier to configure the
transmitter for legacy behavior. Always verify mA Output Action after setting HART Address.
Description
The primary mA Output reports process data as configured.
The primary mA Output is fixed at 4 mA and does not report process
data.
Configure burst parameters
ProLink III
Field Communicator Configure > Manual Setup > Inputs/Outputs > Communications > Set Up Burst Mode
Overview
Burst mode is a mode of communication during which the transmitter regularly
broadcasts HART digital information over the mA Output. The burst parameters control
the information that is broadcast when burst mode is enabled.
Device Tools > Configuration > Communications > Communications (HART)
Tip
In typical installations, burst mode is disabled. Enable burst mode only if you are using a HART
Triloop.
Procedure
1. Enable Burst Mode.

DescriptionProLink III Field Communicator
The transmitter sends the primary variable (PV) in the configured measurement units in each burst (e.g., 14.0 g/sec,
13.5 g/sec, 12.0 g/sec.
The transmitter sends the PV’s percent of range and the
PV’s actual mA level in each burst (e.g., 25%, 11.0 mA.
The transmitter sends PV, SV, TV, and QV values in measurement units and the PV’s actual milliamp reading in each
burst (e.g., 50 g/sec, 23 °C, 50 g/sec, 0.0023 g/cm3,
11.8 mA.
The transmitter sends four user-specified process variables
in each burst.
• If you set Burst Mode Output to send four user-specified variables, set the four
process variables to be sent in each burst.
• If you set Burst Mode Output to any other option, ensure that the HART variables
are set as desired.

Overview
The HART variables are a set of four variables predefined for HART use. The HART variables
include the Primary Variable (PV), Secondary Variable (SV), Tertiary Variable (TV), and
Quaternary Variable (QV). You can assign specific process variables to the HART variables,
and then use standard HART methods to read or broadcast the assigned process data.
Restriction
The TV is automatically set to match the PV and cannot be configured independently.
Tip
The Tertiary Variable and Quaternary Variable are also called the Third Variable (TV) and Fourth
Variable (FV).

8. When you have finished testing or tuning, disable sensor simulation.
Sensor simulation
Sensor simulation allows you to test the system or tune the loop without having to create
the test conditions in your process. When sensor simulation is enabled, the transmitter
reports the simulated values for mass flow, density, and temperature, and takes all
appropriate actions. For example, the transmitter might apply a cutoff, activate an event,
or post an alert.
When sensor simulation is enabled, the simulated values are stored in the same memory
locations used for process data from the sensor. The simulated values are then used
throughout transmitter functioning. For example, sensor simulation will affect:
• All mass flow rate, temperature, and density values displayed or reported via
outputs or digital communications
• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and
volume inventories
90 Micro Motion Model 1500 Transmitters with Analog Outputs
Page 97
• All mass, temperature, density, or volume values logged to Data Logger
Sensor simulation does not affect any diagnostic values.
Unlike actual mass flow rate and density values, the simulated values are not temperaturecompensated (adjusted for the effect of temperature on the sensor’s flow tubes).
7.2 Back up transmitter configuration
ProLink III provides a configuration upload/download function which allows you to save
configuration sets to your PC. This allows you to back up and restore your transmitter
configuration. This is also a convenient way to replicate a configuration across multiple
