2.1
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
Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1.
Ensure that all transmitter and sensor covers and seals are closed.
DANGER!
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. The transmitter is
self-switching and will automatically detect the supply voltage. When using DC
power, a minimum of 1.5 amps of startup current is required. During this period,
Alert 009 is active. The diagnostic routines should complete in approximately
30 seconds. For transmitters with a display, the status LED will turn green and begin
to flash 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
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.
Configuration and Use Manual

Quick start
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.

any available method.
•
Read the value for Mass Flow Rate on the transmitter display.
•
Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in
the Process Variables panel.
•
Connect to the transmitter with the Field Communicator and read the value for Mass

•
Check the characterization parameters.
•
Review the troubleshooting suggestions for flow measurement issues.
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.
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 &gt; Calibration &gt; Zero Verification and
Calibration &gt; 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.

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 factory.
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 &plusmn;
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.

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.
Note
Although you cannot define a special measurement unit using the display, you can use the display to
select an existing special measurement unit, and to view process data using the special
measurement unit.
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 &divide; 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).

Field Communicator Configure &gt; Manual Setup &gt; Measurements &gt; Flow &gt; 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.
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
0 to 51.2 seconds
Special
0 to 40.96 seconds
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.

Field Communicator Configure &gt; Manual Setup &gt; Measurements &gt; Flow &gt; Mass Flow Cutoff
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.
Configuration and Use Manual
21
Configure process measurement
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:
•

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.

Interaction between Volume Flow Cutoff and mAO Cutoff
Volume Flow Cutoff defines the lowest liquid volume flow value that the transmitter will
report as measured. mAO Cutoff defines the lowest flow rate that will be reported via the
mA Output. If mA Output Process Variable is set to Volume Flow Rate, the volume flow rate
reported via the mA Output is controlled by the higher of the two cutoff values.
Volume Flow Cutoff affects both the volume flow values reported via the outputs and the
volume flow values used in other transmitter behavior (e.g., events defined on the volume
flow).
mAO Cutoff affects only flow values reported via the mA Output.
Example: Cutoff interaction with mAO Cutoff lower than Volume Flow Cutoff
Configuration:
•
mA Output Process Variable: Volume Flow Rate
•
Frequency Output Process Variable: Volume Flow Rate
•
AO Cutoff: 10 l/sec
•
Volume Flow Cutoff: 15 l/sec
Result: If the volume flow rate drops below 15 l/sec, volume flow will be reported as 0, and
0 will be used in all internal processing.
Example: Cutoff interaction with mAO Cutoff higher than Volume Flow Cutoff

• The device being polled (slave) cannot have special units set for density.
Otherwise, the master will reject the base density and report the following alarm:
A115: No External Input or Polled Data Alert
• On the slave side, setup the HART Primary Variable for Base Density. The master
will reject anything other than Base Density for the HART Primary Variable and
trigger an A115 alarm.
• The density units on the transmitter and the polled device can be different as
long as they can be classified as density units; for example, kg/m3 and g/cm3.
The transmitter converts the polled units into compatible specified units.

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.
Note
Although you cannot define a special measurement unit using the display, you can use the display to
select an existing special measurement unit, and to view process data using the special
measurement unit.
Procedure
1.
Specify Base Gas Standard Volume Unit.
Base Gas Standard Volume Unit is the existing gas standard volume 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 Gas Standard Volume Flow Conversion Factor as follows:
a. x base units = y special units
b. Gas Standard Volume Flow Conversion Factor = x &divide; y
4.
Enter the Gas Standard Volume Flow Conversion Factor.
The original gas standard volume flow value is divided by this conversion factor.
5.
Set Gas Standard Volume Flow Label to the name you want to use for the gas
standard volume flow unit.
6.
Set Gas Standard Volume Total Label to the name you want to use for the gas
standard volume total and gas standard volume 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 gas standard volume flow
You want to measure gas standard volume flow in thousands of standard cubic feet per
minute.
1.
Set Base Gas Standard Volume Unit to SCF.
2.
Set Base Time Unit to minutes (min).
3.
Calculate the conversion factor:
a. 1 thousands of standard cubic feet per minute = 1000 cubic feet per minute
b. Gas Standard Volume Flow Conversion Factor = 1 &divide; 1000 = 0.001 standard

Overview
Gas Standard Volume Flow Cutoff specifies the lowest gas standard volume flow rate that
will reported as measured. All gas standard volume flow rates below this cutoff will be
reported as 0.
Procedure
Set Gas Standard Volume Flow Cutoff to the value you want to use.
The default value for Gas Standard Volume Flow Cutoff is 0.0. The lower limit is 0.0. There
is no upper limit.
Interaction between Gas Standard Volume Flow Cutoff and
mA Output Cutoff
Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume 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 Gas
Standard Volume Flow Rate, the volume flow rate reported via the mA Output is controlled by
the higher of the two cutoff values.
Gas Standard Volume Flow Cutoff affects both the gas standard volume flow values
reported via outputs and the gas standard volume flow values used in other transmitter
behavior (e.g., events defined on gas standard volume flow).
mA Output Cutoff affects only flow values reported via the mA Output.
Example: Cutoff interaction with mA Output Cutoff lower than Gas Standard Volume

Result: If the gas standard volume flow rate drops below 15 SLPM, the volume flow will be
reported as 0, and 0 will be used in all internal processing.

Overview
Flow Direction controls how forward flow and reverse flow affect flow measurement and
reporting.
Flow Direction is defined with respect to the flow arrow on the sensor:
•
Forward flow (positive flow) moves in the direction of the flow arrow on the sensor.
•
Reverse flow (negative flow) moves in the direction opposite to the flow arrow on
the sensor.
Tip
Micro Motion sensors are bidirectional. Measurement accuracy is not affected by actual flow
direction or the setting of the Flow Direction parameter.

Note
Two-phase flow is also referred to as slug flow.
40
Micro Motion Model 1700 Transmitters with Analog Outputs
Configure process measurement
Procedure
1.
Set Two-Phase Flow Low Limit to the lowest density value that is considered normal
in your process.
Values below this will cause the transmitter to post Alert A105 (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/cm&sup3;, even if you configured another
unit for density measurement.
The default value for Two-Phase Flow Low Limit is 0.0 g/cm&sup3;. The range is 0.0 to
10.0 g/cm&sup3;.
2.
Set Two-Phase Flow High Limit to the highest density value that is considered
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/cm&sup3;, even if you configured another
unit for density measurement.
The default value for Two-Phase Flow High Limit is 5.0 g/cm&sup3;. The range is 0.0 to
10.0 g/cm&sup3;.
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.
Configuration and Use Manual
41
Configure process measurement
•
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.

Field Communicator Configure &gt; Manual Setup &gt; Measurements &gt; Density &gt; Density Damping
Overview
Density Damping controls the amount of damping that will be applied to the line density
value.
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
Damping range
Normal
0 to 51.2 seconds
Special
0 to 40.96 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.
42
Micro Motion Model 1700 Transmitters with Analog Outputs
Configure process measurement
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
The value you enter is automatically rounded off to the nearest valid value. The valid values
for Density Damping depend on the setting of Update Rate.

from the damped density value rather than the measured density value. Density Damping
does not affect gas standard volume measurement.

Configure process measurement
Overview
Temperature Damping controls the amount of damping that will be applied to the line
temperature value, when the on-board temperature data is used (RTD).
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
Tip
Temperature Damping affects all process variables, compensations, and corrections that use
temperature data from the sensor.
Procedure
Enter the value you want to use for Temperature Damping.
The default value is 4.8 seconds. 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
measurement because the reported value is being averaged over time.
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
The value you enter is automatically rounded off to the nearest valid value. Valid values for
Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, … 38.4.
4.6.3
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.
4.6.4
Configure Temperature Input
Temperature data from the on-board temperature sensor (RTD) is always available.
Optionally, you can set up an external temperature device and use external temperature
data.
Configuration and Use Manual
45
Configure process measurement
Choose Device Tools &gt; Configuration &gt; Process Measurement &gt; Temperature &gt; Source.
4.7
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.
Tip
Not all sensors or applications require pressure compensation. The pressure effect for a specific
sensor model can be found in the product data sheet located at www.emerson.com. If you are
uncertain about implementing pressure compensation, contact customer service.
Prerequisites
You will need the flow factor, density factor, and calibration pressure values for your
sensor.

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.
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.

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.
Note
For transmitter software v5.0 and later, if you change LRV and URV from the factory default values,
and you later change mA Output Process Variable, LRV and URV will not reset to the default values.
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.
74
Micro Motion Model 1700 Transmitters with Analog Outputs
Integrate the meter with the control system
• 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.
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.

MAO Cutoff
AO Cutoff (Analog Output Cutoff) specifies the lowest mass flow rate, volume flow rate, or

below AO Cutoff will be reported as 0.
Configuration and Use Manual
75
Integrate the meter with the control system
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.
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
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:
•
•
76
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.

Added Damping
Overview
Added Damping controls the amount of damping that will be applied to the mA Output.
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.

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.
Example: Damping interaction
Configuration:
•
Flow Damping = 1 second
•
mA Output Source = Mass Flow Rate
•
mA Output Damping = 2 seconds
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.

2.
Set Frequency Output Scaling Method.
Option
Description
Frequency=Flow (default)
Frequency calculated from flow rate
Pulses/Unit
A user-specified number of pulses represents one flow unit
Units/Pulse
A pulse represents a user-specified number of flow units
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
The maximum flow rate that you want the Frequency Output to report.

Frequency Output Fault Action controls the behavior of the Frequency 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 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

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. Your
transmitter may have zero or one Discrete Output: Channel B can be configured as a
Frequency Output or a Discrete Output.
Restriction
Before you can configure the Discrete Output, you must configure a channel to operate as a Discrete
Output.
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%.
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.

Overview
Digital Communications Fault Actionspecifies the values that will be reported via digital
communications if the device encounters an internal fault condition.
Procedure
Set Digital Communications Fault Action as desired.
The default setting is None.
Restrictions
• If mA Output Fault Action or Frequency Output Fault Action is set to None, Digital
Communications Fault Action should also be set 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.
• If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or
Frequency Output Fault Action to None. If you try to do this, the transmitter will not accept the
configuration.

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:

outputs or digital communications
•
The mass total and mass inventory values
•
All volume calculations and data, including reported values, volume totals, and

•
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).

Perform temperature calibration
Options for measurement support
Micro Motion provides several measurement support procedures to help you evaluate and
maintain your flowmeter's accuracy.
The following methods are available:
•
Smart Meter Verification (SMV) 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.
•
Meter validation compares flowmeter measurements reported by the transmitter to
an external measurement standard. Meter validation requires one data point.
•
Calibration establishes the relationship between a process variable and the signal
produced at the sensor. You can calibrate the flowmeter for zero, density, and
temperature. Density and temperature calibration require two data points (low and
high) and an external measurement for each.
Tips
•
Perform SMV at regular intervals to get the best data on your meter's performance.
•
To prove the meter against a regulatory standard, or to correct measurement error, use
meter validation and meter factors.
•
Before performing a field calibration, contact customer support to see if there is an
alternative. In many cases, field calibrations have a negative effect on measurement accuracy.

You can run an SMV test, view and interpret the results, and set up automatic execution.
9.2.1
SMV requirements
To use SMV, the transmitter must be paired with an enhanced core processor.
See Table 9‐1 for the minimum version of the transmitter, enhanced core processor, and
communication tool needed to support SMV. (If you are going to perform SMV using the
display, only the transmitter and enhanced core processor versions apply.)

SMV test preparation
Although it is not necessary to match factory conditions or change the transmitter's
configuration during an SMV test, the test will run more smoothly when conditions are
stable.
120
Micro Motion Model 1700 Transmitters with Analog Outputs
Measurement support
SMV has an output mode called Continuous Measurement that allows the transmitter to keep
measuring while the test is in progress. If you choose to run the test in Last Measured Value
or Fault modes instead, the transmitter outputs will be held constant for the two minute
duration of the test. If control loops depend on transmitter outputs, take appropriate
action.
Avoid process instability during the test. If conditions are too unstable, the SMV test will
abort. To maximize process stability:
•
Maintain a constant fluid pressure and temperature.
•
Avoid changes to fluid composition, e.g., two-phase flow or settling.
•
Maintain a constant flow rate.
Tips
9.2.3
•
The SMV test runs best when flow is stopped through the sensor.
•
SMV is not affected by any configured transmitter parameters for flow, density, or
temperature.

Understanding SMV results
When the SMV test is completed, the result is reported as Pass, Fail, or Abort. (Some tools
report the Fail result as Advisory instead.)
Pass
Smart Meter Verification does a statistical check between the factory baseline
value and the current Smart Meter Verification result. Pass indicates that the two
values are statistically the same.
Fail
The current SMV value is statistically different than the factory baseline value.
•
If the meter passes the second test, the first result can be ignored.
•
If the meter fails the second test, the flow tubes may be damaged. Call
customer support.
Abort A problem occurred with the meter verification test (such as process instability)
or you stopped the test manually. See Table 9‐3 for a list of abort codes, a

Restriction
PVR, TBR, and TMR are available only with a transmitter that is ordered with one of these software
options:
•
An 800 Enhanced Core Processor version 4.4 and later
•
HART with HART 7 enabled in order to view process variables over HART (default)
Restriction
PVR, TBR, and TMR process variables are available only over HART with HART 7 enabled

132
Micro Motion Model 1700 Transmitters with Analog Outputs
Measurement support
9.3.1
PVR, TBR, and TMR applications
PVR, TBR, and TMR are applications designed to provide more accurate process data in the
presence of multiple phases. For example, if bubbles are present in the process fluid, or the
process fluid is flashing, the volume measurements are often incorrect.
Production Volume Reconciliation (PVR)
•
Provides oil and water volumes through density-based calculations for both line and
reference conditions
•
Detects bubble entrainment or flashing in the sensor, and can correct volumes
accordingly
•
Best for undersized three-phase separators that frequently have intermittent gas or
water contamination in the oil leg
•
Offers a simple, low-cost solution for net oil and net water measurement for twophase separators
Transient Bubble Remediation (TBR)
•
Used with single-component liquid streams that may experience intermittent low
levels of gas entrainment, that is, gas carryunder
•
Enables accurate measurement of a single fluid during periods of entrained gas by
providing a substitute density value based on the immediately preceding process
density (standard configuration)
•
Tracks total time of aerated flow to assist in diagnosing process issues that may
cause aeration
Transient Mist Remediation (TMR)
•
Used with gas streams that may experience intermittent low levels of liquid
entrainment, i.e., liquid carry-over
•
Allows gas measurement to continue during periods of entrained liquid (mist) by
providing a substitute flow rate value based on the immediately preceding process
flow rate
•
Returns to reporting the measured flow rate when the mist interval is over,
increased or decreased by a maximum of 10%, until flow totals are appropriately
adjusted for the unmeasured flow
•
Provides an indication of the amount of time that liquid was present in the stream —
identifying process improvements to reduce gas stream contamination

Piecewise linearization (PWL) for calibrating
gas meters
Piecewise linearization (PWL) can linearize the measurements of flow meters for greater
accuracy in order to measure gas over a wide range of flow rates. PWL does not apply when
measuring liquid flow. When better accuracy is required over the published gas
measurement specifications, an Emerson-approved independent gas laboratory can
calibrate gas up to 10 PWL adjustment points.
PWL configuration and calibration information is not available through HART.
For more information, see the white paper, The Practical Application of Multi‐Point Piecewise
Linear Interpolation (PWL) and Other Developing Trends with Coriolis Meters for Natural Gas
Custody Transfer Applications, available at www.emerson.com.
The PWL feature is available in ProLink III, so you can view the points that are stored and
capture them in the uploaded and downloaded configuration files.

Overview
Meter validation compares flowmeter measurements reported by the transmitter to an
external measurement standard. If the transmitter value for mass flow, volume flow, or
density measurement is significantly different from the external measurement standard,
you may want to adjust the corresponding meter factor. The flowmeter’s actual
measurement is multiplied by the meter factor, and the resulting value is reported and
used in further processing.
Prerequisites
Identify the meter factor(s) that you will calculate and set. You may set any combination of
the three meter factors: mass flow, volume flow, and density. Note that all three meter
factors are independent:
•
The meter factor for mass flow affects only the value reported for mass flow.
•
The meter factor for density affects only the value reported for density.
•
The meter factor for volume flow affects only the value reported for volume flow or
gas standard volume flow.
Important
To adjust volume flow, you must set the meter factor for volume flow. Setting a meter factor for
mass flow and a meter factor for density will not produce the desired result. The volume flow
calculations are based on original mass flow and density values, before the corresponding meter
factors have been applied.
If you plan to calculate the meter factor for volume flow, be aware that validating volume
in the field may be expensive, and the procedure may be hazardous for some process
fluids. Therefore, because volume is inversely proportional to density, an alternative to
direct measurement is to calculate the meter factor for volume flow from the meter factor
for density. See Section 9.6.1 for instructions on this method.
Configuration and Use Manual
135
Measurement support
Obtain a reference device (external measurement device) for the appropriate process
variable.
Important
For good results, the reference device must be highly accurate.
Procedure
1.
Determine the meter factor as follows:
a. Set the meter factor to 1 to take a sample measurement.
b. Measure the same sample using the reference device.
c. Calculate the meter factor using the following formula:
ReferenceMeasurement
NewMeterFactor = ConfiguredMeterFactor
FlowmeterMeasurement
2.
Ensure that the calculated meter factor does not fall outside 0.98 and 1.02. If the
meter factor is outside these limits, contact customer service.
3.
Configure the meter factor in the transmitter.
Example: Calculating the meter factor for mass flow
The flowmeter is installed and validated for the first time. The mass flow measurement
from the transmitter is 250.27 lb. The mass flow measurement from the reference device
is 250 lb. The mass flow meter factor is calculated as follows:
MeterFactorMassFlow = 1
250
250.27
= 0.9989
The first meter factor for mass flow is 0.9989.
One year later, the flowmeter is validated again. The mass flow measurement from the
transmitter is 250.07 lb. The mass flow measurement from the reference device is
250.25 lb. The new mass flow meter factor is calculated as follows:
MeterFactorMassFlow = 0.9989
250.25
250.07
= 0.9996
The new meter factor for mass flow is 0.9996.
9.6.1
Alternate method for calculating the meter factor for
volume flow
The alternate method for calculating the meter factor for volume flow is used to avoid the
difficulties that may be associated with the standard method.
This alternate method is based on the fact that volume is inversely proportional to density.
It provides partial correction of the volume flow measurement by adjusting for the portion
of the total offset that is caused by the density measurement offset. Use this method only
when a volume flow reference is not available, but a density reference is available.

Perform a (standard) D1 and D2 density
calibration
Density calibration establishes the relationship between the density of the calibration
fluids and the signal produced at the sensor. Density calibration includes the calibration of
the D1 (low-density) and D2 (high-density) calibration points.
Important
Micro Motion flowmeters 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
customer support before calibrating the flowmeter.
Tip
Use meter validation and meter factors, rather than calibration, to prove the meter against a
regulatory standard or to correct measurement error.
Prerequisites
•
During density calibration, the sensor must be completely filled with the calibration
fluid, and flow through the sensor must be at the lowest rate allowed by your
application. This is usually accomplished by closing the shutoff valve downstream
from the sensor, then filling the sensor with the appropriate fluid.
•
D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (highdensity) fluid. You may use air and water.

service has access to this parameter. If this is the case, contact customer service
before continuing.
•
The calibrations must be performed without interruption, in the order shown. Make
sure that you are prepared to complete the process without interruption.
•
Before performing the calibration, record your current calibration parameters. You
can do this by saving the current configuration to a file on the PC. If the calibration
fails, restore the known values.

Perform a D3 and D4 density calibration (TSeries sensors only)
For T-Series sensors, the optional D3 and D4 calibration could improve the accuracy of the
density measurement if the density of your process fluid is less than 0.8 g/cm3 or greater
than 1.2 g/cm3 .
If you perform the D3 and D4 calibration, note the following:
•
Do not perform the D1 and D2 calibration.
•
Perform the D3 calibration if you have one calibrated fluid.
•
Perform both the D3 and D4 calibrations if you have two calibrated fluids (other
than air and water). The calibrations must be performed without interruption, in the
order shown. Make sure that you are prepared to complete the process without
interruption.
Prerequisites
•
During density calibration, the sensor must be completely filled with the calibration
fluid, and flow through the sensor must be at the lowest rate allowed by your
application. This is usually accomplished by closing the shutoff valve downstream
from the sensor, then filling the sensor with the appropriate fluid.
•
For D3 density calibration, the D3 fluid must meet the following requirements:
•
•
9.8.1
-
Minimum density of 0.6 g/cm3
-
Minimum difference of 0.1 g/cm3 between the density of the D3 fluid and the
density of water. The density of the D3 fluid may be either greater or less than
the density of water.
For D4 density calibration, the D4 fluid must meet the following requirements:
-
Minimum density of 0.6 g/cm3
-
Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the
density of the D3 fluid. The density of the D4 fluid must be greater than the
density of the D3 fluid.
-
Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the
density of water. The density of the D4 fluid may be either greater or less than

Status LED states
The status LED on the transmitter indicates whether or not alerts are active. If alerts are
active, view the alert list to identify the alerts, then take appropriate action to correct the
alert condition.
Your transmitter has a status LED only if it has a display.
If the transmitter has a display and LED Blinking is disabled, the status LED does not flash to
indicate an unacknowledged alert.

Troubleshooting
10.8
Using sensor simulation for troubleshooting
When sensor simulation is enabled, the transmitter reports user-specified values for basic
process variables. This allows you to reproduce various process conditions or to test the
system.
You can use sensor simulation to help distinguish between legitimate process noise and
externally caused variation. For example, consider a receiving device that reports an
unexpectedly erratic density value. If sensor simulation is enabled and the observed
density value does not match the simulated value, the source of the problem is likely to be
somewhere between the transmitter and the receiving device.
Sensor simulation requires an Enhanced Core and a communication device.
Important
When sensor simulation is active, the simulated value is used in all transmitter outputs and
calculations, including totals and inventories, volume flow calculations, and concentration
calculations. Disable all automatic functions related to the transmitter outputs and place the loop in
manual operation. Do not enable simulation mode unless your application can tolerate these effects,
and be sure to disable simulation mode when you have finished testing.
10.9
Check power supply wiring
If the power supply wiring is damaged or improperly connected, the transmitter may not
receive enough power to operate properly.
Prerequisites
•
You will need the installation manual for your transmitter.
•
When using DC power, a minimum of 1.5 amps of startup current is required.
Procedure
1.
Use a voltmeter to test the voltage at the transmitter’s power supply terminals.
• If the voltage is within the specified range, you do not have a power supply
problem.
• If the voltage is low, ensure that the power supply is adequate at the source, the
power cable is sized correctly, there is no damage to the power cable, and an
appropriate fuse is installed.
• If there is no power, continue with this procedure.
2.
Before inspecting the power supply wiring, disconnect the power source.
CAUTION!
If the transmitter is in a hazardous area, wait five minutes after disconnecting the
power.
3.
Ensure that the terminals, wires, and wiring compartment are clean and dry.

Troubleshooting
4.
Ensure that the power supply wires are connected to the correct terminals.
5.
Ensure that the power supply wires are making good contact, and are not clamped
to the wire insulation.
6.
Inspect the voltage label inside the wiring compartment.
The voltage supplied to the transmitter should match the voltage specified on the
label.
7.
Reapply power to the transmitter.
CAUTION!
If the transmitter is in a hazardous area, do not reapply power to the transmitter with
the housing cover removed. Reapplying power to the transmitter while the housing
cover is removed could cause an explosion.
8.
Test the voltage at the terminals.
If there is no power, contact customer service.
10.10
Check sensor-to-transmitter wiring
A number of power-supply and output problems may occur if the wiring between the
sensor and the transmitter is improperly connected, or if the wiring becomes damaged.
Be sure to check all wiring segments:
•
If you have a 4-wire transmitter, check the wiring between the transmitter and the
core processor.
•
If you have a 9-wire transmitter, check the wiring between the transmitter and the
sensor junction box.
•
If you have a remote transmitter with remote core processor, check the wiring
between the transmitter and the core processor and the wiring between the core
processor and the sensor junction box.
Prerequisites
You will need the installation manual for your transmitter.

You will need:
•
A copy of your transmitter installation manual
•
A 250–600 Ω resistor
•
A Field Communicator
Configuration and Use Manual
171
Troubleshooting
•
Optional: the HART Application Guide, available at www.hartcomm.org
Procedure
1.
Verify that the loop wires are connected as shown in the wiring diagrams in the
transmitter installation manual.
If your HART network is more complex than the wiring diagrams in the transmitter
installation manual, contact either customer service or the HART Communication
Foundation.
2.
Disconnect the primary mA Output wiring from the transmitter.
3.
Install a 250–600 Ω resistor across the transmitter’s primary mA Output terminals.
4.
Check the voltage drop across the resistor (4–20 mA = 1–5 VDC for a 250 Ω
resistor).
If voltage drop is less than 1 VDC, add resistance to achieve a voltage drop of greater
than 1 VDC .
5.
Connect a Field Communicator directly across the resistor and attempt to
communicate (poll).
If communication with the transmitter cannot be established, the transmitter may
need service. Contact customer service.
10.14
Check HART Address and mA Output Action
If the transmitter is producing a fixed current from the mA Output, the mA Output Action
parameter may be set incorrectly.
When the mA Output Action parameter is set to Fixed, the mA Output produces a fixed
value, and does not report process data or implement its fault action.
When HART Address is changed, some configuration tools will automatically change mA
Output Action.
Tip
Always verify mA Output Action after setting or changing HART Address.
Procedure
1.
Set HART Address as appropriate for your HART network.
The default address is 0. This is the recommended value unless the transmitter is in a
multidrop network.
2.

HART burst mode is normally disabled, and should be enabled only if a HART Triloop is
being used.
10.16
1.
Check to see if burst mode is enabled or disabled.
2.
If burst mode is enabled, disable it.
Check the trimming of the mA Output
If the trim values for the mA Output are inaccurate, the transmitter will under-compensate
or over-compensate the output.
10.17
1.
Trim the output, following the standard procedure.
2.
If this does not correct the problem, contact customer support.
Check Lower Range Value and Upper Range
Value
If the process variable assigned to the mA Output falls below the configured Lower Range
Value (LRV) or rises above the configured Upper Range Value (URV), the meter will post a
saturation alert (A100), then perform the configured fault action.
10.18
1.
Record your current process conditions.
2.
Check the configuration of the LRV and URV.
Check mA Output Fault Action
mA Output Fault Action controls the behavior of the mA Output if the transmitter
encounters an internal fault condition. If the mA Output is reporting a constant value
below 4 mA or above 20 mA, the transmitter may be in a fault condition.
1.
Check the status alerts for active fault conditions.
2.
If there are active fault conditions, the transmitter is performing correctly. If you
want to change its behavior, consider the following options:
• Change the setting of mA Output Fault Action.
• For the relevant status alerts, change the setting of Alert Severity to Ignore.
Restriction
For some status alerts, Alert Severity is not configurable.

Check for radio frequency interference (RFI)
The transmitter's Frequency Output or Discrete Output can be affected by radio frequency
interference (RFI). Possible sources of RFI include a source of radio emissions, or a large
transformer, pump, or motor that can generate a strong electromagnetic field. Several
methods to reduce RFI are available. Use one or more of the following suggestions, as
appropriate to your installation.
Procedure
•
10.20
Use shielded cable between the output and the receiving device.
-
Terminate the shielding at the receiving device. If this is impossible, terminate
the shielding at the cable gland or conduit fitting.
-
Do not terminate the shielding inside the wiring compartment.
-
360-degree termination of shielding is unnecessary.
•
Eliminate the RFI source.
•
Move the transmitter.
Check Frequency Output Scaling Method
If Frequency Output Scaling Method is set incorrectly, the Frequency Output may report an
incorrect value.
10.21
1.
Verify the configuration of the Frequency Output.
2.
If you changed the setting of Frequency Output Scaling Method, check the settings
of all other Frequency Output parameters.
Check Frequency Output Fault Action
The Frequency Output Fault Action controls the behavior of the Frequency Output if the
transmitter encounters an internal fault condition. If the Frequency Output is reporting a
constant value, the transmitter may be in a fault condition.
1.
Check the status alerts for active fault conditions.
2.
If there are active fault conditions, the transmitter is performing correctly. If you
want to change its behavior, consider the following options:
• Change the setting of Frequency Output Fault Action.
• For the relevant status alerts, change the setting of Alert Severity to Ignore.

Check Flow Direction
If Flow Direction is set inappropriately for your process, the transmitter may report flow
data that is not appropriate for your requirements.
The Flow Direction parameter interacts with actual flow direction to affect flow values,
flow totals and inventories, and output behavior. For the simplest operation, actual
process flow should match the flow arrow that is on the side of the sensor case.
Procedure
10.23
1.
Verify the actual direction of process flow through the sensor.
2.
Verify the configuration of Flow Direction.
Check the cutoffs
If the transmitter cutoffs are configured incorrectly, the transmitter may report zero flow
when flow is present, or very small amounts of flow under no-flow conditions.
There are separate cutoff parameters for mass flow rate, volume flow rate, gas standard
volume flow rate (if applicable), and density. There is an independent cutoff for the mA
Output on your transmitter. The interaction between cutoffs sometimes produces
unexpected results.
Procedure
Verify the configuration of all cutoffs.
Tip
For typical applications, set Mass Flow Cutoff to 0.5% of the nominal flow rate of the attached sensor.
See the sensor specifications for nominal flow rate data.
10.24
Check for two-phase flow (slug flow)
Two-phase flow can cause rapid changes in the drive gain. This can cause a variety of
measurement issues.
1.
Check for two-phase flow alerts (e.g., A105).
If the transmitter is not generating two-phase flow alerts, verify that two-phase flow
limits have been set. If limits are set, two-phase flow is not the source of your
problem.
2.
Check the process for cavitation, flashing, or leaks.
3.
Monitor the density of your process fluid output under normal process conditions.
4.
Check the settings of Two-Phase Flow Low Limit, Two-Phase Flow High Limit, and
Two-Phase Flow Timeout.
Configuration and Use Manual

Tip
You can reduce the occurrence of two-phase flow alerts by setting Two-Phase Flow Low Limit
to a lower value, Two-Phase Flow High Limit to a higher value, or Two-Phase Flow Timeout to
a higher value. Micro Motion recommends leaving the Two-Phase Flow High Limit at the
default value.
10.25
Check the drive gain
Excessive or erratic drive gain may indicate any of a variety of process conditions or sensor
problems.

The F300/H300/CMF400 fixed resistor applies to only certain specific sensor releases. Contact
customer support for more information.
There should be no open circuits, that is, no infinite resistance readings. The left
pickoff and right pickoff readings should be the same or very close (&plusmn;5 Ω). If there
are any unusual readings, repeat the coil resistance tests at the sensor junction box
to eliminate the possibility of faulty cable. The readings for each coil pair should
match at both ends.
5.
Test the terminals in the sensor junction box for shorts to case.
Test results will be inconclusive with nonconductive process fluids such as
hydrocarbons.
a. Leave the terminal blocks disconnected.
b. Remove the lid of the junction box.
c. Testing one terminal at a time, place a DMM lead on the terminal and the other
lead on the sensor case.
With the DMM set to its highest range, there should be infinite resistance on
each lead. If there is any resistance at all, there is a short to case.
6.
Test the resistance of junction box terminal pairs.
a. Test the brown terminal against all other terminals except the red one.
b. Test the red terminal against all other terminals except the brown one.
c. Test the green terminal against all other terminals except the white one.
d. Test the white terminal against all other terminals except the green one.
e. Test the blue terminal against all other terminals except the gray one.
f. Test the gray terminal against all other terminals except the blue one.
g. Test the orange terminal against all other terminals except the yellow and violet
ones.
h. Test the yellow terminal against all other terminals except the orange and violet
ones.
i. Test the violet terminal against all other terminals except the yellow and orange
ones.

A.3.1
Enter a floating-point value using the display
Certain configuration values (for example, Lower Range Value and Upper Range Value) are
entered as floating-point values. The display supports both decimal notation and
exponential notation for floating-point values.
The display allows you to enter a maximum of 8 characters, including the sign. The decimal
point is not counted as a character. Exponential notation is used to enter values that
require more than 8 characters.
Enter a floating-point value using decimal notation
Decimal notation allows you to enter values between –9999999 and 99999999. You can
use the decimal point to enter values with a precision of 0 through 4 (4 characters to the
right of the decimal point).
Decimal values entered via the display must meet the following requirements:
•
They can contain a maximum of 8 digits, or 7 digits plus a minus sign (−) to indicate
a negative number.
•
They can contain a decimal point. The decimal point does not count as a digit. The
decimal point must be positioned so that the precision of the value does not exceed
4.
When you first enter the configuration screen, the current configuration value is displayed
in decimal notation, and the active character is flashing. If the value is positive, no sign is
displayed. If the value is negative, a minus sign is displayed.

•
To change the sign of the value:
-
If the current value is negative, activate Select until the minus sign is flashing,
then activate Scroll until the space is blank.
-
If the current value is positive and there is a blank space at the left of the value,
activate Select until the cursor is flashing under the blank space, then activate
Scroll until the minus sign appears.
-
If the current value is positive and there is no blank space at the left of the value,
activate Select until the cursor is flashing under the leftmost digit, then activate
Scroll until the minus sign appears.
To move the decimal point:
1. Activate Select until the decimal point is flashing.
2. Activate Scroll.
The decimal point is removed from its current position.
3. Activate Select and watch the position of the decimal point.
As the cursor moves to the left, the decimal point will flash between each pair of
digits, up to a maximum precision of four (four digits to the right of the decimal
point).
Tip

Connect with ProLink III
A connection from ProLink III to your transmitter allows you to read process data,
configure the transmitter, and perform maintenance and troubleshooting tasks.
B.2.1
Connection types supported by ProLink III
Different connection types are available for connecting from ProLink III to the transmitter.
Choose the connection type appropriate to your network and the tasks you intend to
perform.
The transmitter supports the following ProLink III connection types:
•
Service port connections
•
HART/Bell 202 connections
•
HART/RS-485 connections
•
Modbus/RS-485 8-bit connections (Modbus RTU)
•
Modbus/RS-485 7-bit connections (Modbus ASCII)
When selecting a connection type, consider the following:
202
•
Service port connections are specialized Modbus/RS-485 connections that use
standard connection parameters and a standard address that are already defined in
ProLink III. A service port connection is the preferred connection.
•
HART/Bell 202 connections use standard HART connection parameters that are
already defined in ProLink III. The only parameter you must configure is the
transmitter address.
•
Some connection types require opening the wiring compartment or the power
supply compartment. These connection types should be used only for temporary
connections, and may require extra safety precautions.
•
When you are using a HART connection, ProLink III will not allow you to open more
than one window at a time. This is done to manage network traffic and optimize
speed.

B.2.2
You cannot make concurrent Modbus connections if the connections use the same
terminals. You can make concurrent Modbus connections if the connections use
different terminals.
Connect with ProLink III to the service port
CAUTION!
If the transmitter is in a hazardous area, do not use a service port connection. Service port
connections require opening the wiring compartment, and opening the wiring compartment
while the transmitter is powered up could cause an explosion. To connect to the transmitter in
a hazardous environment, use a connection method that does not require removing the
transmitter housing cover.

Frequently asked questions

Read the value for Mass Flow Rate on the transmitter display, connect to the transmitter with ProLink III and read the value for Mass Flow Rate in the Process Variables panel, or connect to the transmitter with the Field Communicator and read the value for Mass Flow Rate.

In most cases, the factory zero is more accurate than the field zero. Do not zero the meter unless the zero is required by site procedures, or the stored zero value fails the zero verification procedure.

Ensure that all transmitter and sensor covers and seals are closed. Then, turn on the electrical power at the power supply. The transmitter will automatically perform diagnostic routines.
