2.1Power 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.
Quick start
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 Manual5
Quick start
2.2Check 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.

2.3Make a startup connection to the transmitter
For all configuration tools except the display, you must have an active connection to the
transmitter to configure the transmitter. 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.

Important
If you are changing communications parameters for the connection type that you are using, you will
lose the connection when you write the parameters to the transmitter. Reconnect using the new
parameters.
Procedure
1.To change the communications parameters using ProLink III, choose Device Tools >

2.To change the communications parameters using the Field Communicator, choose
Check to see that the mass flow rate reported by the transmitter is accurate. You can use
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
Flow Rate.
Configuration and Use Manual7
Quick start
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.
2.6Verify 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 > 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.
8Micro Motion Model 1700 Transmitters with Analog Outputs
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.

2.6.1Terminology used with zero verification and zero
calibration
TermDefinition
ZeroIn general, the offset required to synchronize the left pickoff and the right
pickoff under conditions of zero flow. Unit = microseconds.
Factory ZeroThe zero value obtained at the factory, under laboratory conditions.
Field ZeroThe zero value obtained by performing a zero calibration outside the fac-
tory.
Prior ZeroThe 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 ZeroThe 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 ZeroThe 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 StabilityA 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 CalibrationThe procedure used to determine the zero value.
Zero TimeThe time period over which the Zero Calibration procedure is performed.
Unit = seconds.
Field Verification ZeroA 3-minute running average of the Live Zero value, calculated by the
transmitter. Unit = configured mass flow measurement unit.
Zero VerificationA procedure used to evaluate the stored zero and determine whether or
not a field zero can improve measurement accuracy.

Field Communicator Configure > Manual Setup > Measurements > Special Units > Mass Special 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 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).
1.Set Base Mass Unit to Pounds (lb).
2.Set Base Time Unit to Seconds (sec).
3.Calculate Mass Flow Conversion Factor:
Configuration and Use Manual19
Configure process measurement
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.
4.1.2Configure Flow Damping
DisplayNot available
ProLink IIIDevice Tools > Configuration > Process Measurement > Flow
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
Normal
Special
Damping range
0 to 51.2 seconds
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.
20Micro Motion Model 1700 Transmitters with Analog Outputs
Effect of flow damping on volume measurement
Flow damping affects volume measurement for liquid volume data. Flow damping also
affects volume measurement for gas standard volume data. The transmitter calculates
volume data from the damped mass flow data.
Interaction between Flow Damping and mA Output
Damping
In some circumstances, both Flow Damping and mA Output Damping are applied to the
reported mass flow value.
Flow Damping controls the rate of change in flow process variables. mA Output Damping
controls the rate of change reported via the mA Output. If mA Output Process Variable is
set to Mass Flow Rate, and both Flow Damping and mA Output Damping are set to non-zero
values, flow damping is applied first, and the added damping calculation is applied to the
result of the first calculation.
4.1.3Configure Mass Flow Cutoff
Configure process measurement
DisplayNot available
ProLink IIIDevice Tools > Configuration > Process Measurement > Flow
Field Communicator Configure > Manual Setup > Measurements > Flow > 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 Manual21
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
4.2
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
•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.

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.

Configure Volume Flow Cutoff
DisplayNot available
ProLink IIIDevice Tools > Configuration > Process Measurement > Flow
Volume Flow Cutoff specifies the lowest volume flow rate that will be reported as
measured. All volume flow rates below this cutoff are reported as 0.
Procedure
Set Volume Flow Cutoff to the value you want to use.
The default value for Volume Flow Cutoff is 0.0 l/sec (liters per second). The lower limit is
0.

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
Configuration:
•mA Output Process Variable: Volume Flow Rate
•Frequency Output Process Variable: Volume Flow Rate
•AO Cutoff: 15 l/sec
•Volume Flow Cutoff: 10 l/sec
Result:
•If the volume flow rate drops below 15 l/sec but not below 10 l/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 volume flow rate drops below 10 l/sec, both outputs will report zero flow, and
0 will be used in all internal processing.

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.
40Micro 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/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.
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/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.
Configuration and Use Manual41
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.
4.5.3Configure Density Damping
DisplayNot available
ProLink IIIDevice 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.
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.
Damping range
0 to 51.2 seconds
0 to 40.96 seconds
42Micro 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.
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.

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.

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.
4.6.3
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.
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
Configuration and Use Manual45
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.
Configure process measurement
Choose Device Tools > Configuration > Process Measurement > Temperature > Source.
4.7Configure 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.
•For the flow factor and density factor, see the product data sheet for your sensor.
•For the calibration pressure, see the calibration sheet for your sensor. If the data is
If you will use an external pressure value, set Pressure Unit to match the pressure
unit used by the external pressure device.
4.Enter Flow Calibration Pressure for your sensor.
The calibration pressure is the pressure at which your sensor was calibrated, and
defines the pressure at which there is no pressure effect. If the data is unavailable,
enter 20 PSI.
5.Enter Flow Factor for your sensor.
The flow factor is the percent change in the flow rate per PSI. When entering the
value, reverse the sign.
Example: If the flow factor is 0.000004 % per PSI, enter −0.000004 % per PSI.
6.Enter Density Factor for your sensor.
The density factor is the change in fluid density, in g/cm3/PSI. When entering the
value, reverse the sign.

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

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.
74Micro 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
gas standard volume flow rate that will be reported through the mA Output. Any flow rates
below AO Cutoff will be reported as 0.
Configuration and Use Manual75
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:
•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.
Integrate the meter with the control system
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

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.

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

6.4.1Configure Discrete Output Source
DisplayOFF-LINE MAINT > OFF-LINE CONFG > IO > CH B > SET DO > DO SRC
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.

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.
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.

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
•HART/RS-485 over the RS-485 terminals
•Modbus/RS-485 over the RS-485 terminals
•Modbus RTU via the service port
Note
The service port responds automatically to a wide range of connection requests. It is not
configurable.
Configure HART/Bell 202 communications
HART/Bell 202 communications parameters support HART communications with the
transmitter's primary mA terminals over a HART/Bell 202 network.
Basic HART parameters include the HART address, HART tags, and the operation of the
primary mA Output.
HART/Bell 202 communications parameters support HART communication with the
