8 Micro Motion 1700 Transmitters with Analog Outputs
Configuration and Use Manual Quick start
MMI-20019028 June 2022
2 Quick start
2.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks or for process
measurement.
Procedure
1. WARNING
If the transmitter is in a hazardous area, do not remove the housing cover while the transmitter is
powered up. Failure to follow these instructions can cause an explosion resulting in injury or death.
Ensure that all transmitter and sensor covers and seals are closed.
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. 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
ten 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 ten minutes before relying on process measurements. During this warm-up period, you may
observe minor measurement instability or inaccuracy.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect measurement accuracy.
Procedure
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.

2.4 (Optional) Adjust digital communications settings
Change the communications parameters to site-specific values.
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 → Configuration →
Communications.
2. To change the communications parameters using the Field Communicator, choose On-Line Menu →
Configure → Manual Setup → Inputs/Outputs → Communications.
2.5 Verify mass flow measurement
Check to see that the mass flow rate reported by the transmitter is accurate. You can use any available
method.
Procedure
• Read the value for Mass Flow Rate on the transmitter display.
Menu → Operations → Process Variable Values
• 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 a field communicator and read the value for Mass Flow Rate.
Online → Overview → Mass Flow Rate
Postrequisites
If the reported mass flow rate is not accurate:
• Check the characterization parameters.
• Review the troubleshooting suggestions for flow measurement issues.
For information about modifying these values, refer to Configure mass flow measurement.
2.6 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:
Configuration and Use Manual 11
Quick start Configuration and Use Manual
June 2022 MMI-20019028
• The zero is required by site procedures.
• The stored zero value fails the zero verification procedure.
Do not verify the zero or zero the meter if a high-severity alert is active. Correct the problem, then verify the
zero or zero the meter. You may verify the zero or zero the meter if a low-severity alert is active.
Procedure
1. Allow the flowmeter to warm up for at least 20 minutes after applying power.
2. Run the process fluid through the sensor until the sensor temperature reaches the normal process
operating temperature.
3. Stop flow through the sensor by shutting the downstream valve, and then the upstream valve if
available.
4. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is completely full of
process fluid.
5. From ProLink III, choose Device Tools → Calibration → Zero Verification and Calibration → Verify
Zero and wait until the procedure completes.
6. Observe the drive gain, temperature, and density readings. If they are stable, check the Live Zero or
Field Verification Zero value. If the average value is close to 0, you should not need to zero the meter.
7. If the zero verification procedure fails:
a) Confirm that the sensor is completely blocked in, that flow has stopped, and that the sensor is
completely full of process fluid.
b) Verify that the process fluid is not flashing or condensing, and that it does not contain particles
that can settle out.
c) Remove or reduce sources of electromechanical noise if appropriate.
d) Repeat the zero verification procedure.
e) If it fails again, zero the meter.
Postrequisites
Restore normal flow through the sensor by opening the valves.

Term Definition
Manual Zero The zero value stored in the transmitter, typically obtained from a zero calibration
procedure. It may also be configured manually. Also called “mechanical zero” or “stored
zero”.
Live Zero The real-time bidirectional mass flow rate with no flow damping or mass flow cutoff
applied. An adaptive damping value is applied only when the mass flow rate changes
dramatically over a very short interval. Unit = configured mass flow measurement unit.
Zero Stability A laboratory-derived value used to calculate the expected accuracy for a sensor. Under
laboratory conditions at zero flow, the average flow rate is expected to fall within the
range defined by the Zero Stability value (0 ± Zero Stability). Each sensor size and model
has a unique Zero Stability value.
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.

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 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 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 through 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.
4.1.3 Configure Mass Flow Cutoff
Display Not available
ProLink III Device Tools → Configuration → Process Measurement → Flow
Field Communicator Configure → Manual Setup → Measurements → Flow → Mass Flow Cutoff
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. Do
not leave Mass Flow Cutoff at 0.0 g/sec.
Effect of Mass Flow Cutoff on volume measurement
Mass Flow Cutoff does not affect volume measurement. Volume data is calculated from the actual mass data
rather than the reported value.
Volume flow has a separate Volume Flow Cutoff that is not affected by the Mass Flow Cutoff value.
Interaction between Mass Flow Cutoff and mA Output Cutoff
Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as measured. mA
Output Cutoff defines the lowest flow rate that will be reported through mA Output. If mA Output Process
Variable is set to Mass Flow Rate, the mass flow rate reported through 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 through mA Output.

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. Leaving the
volume flow cutoff at 0 is not recommended.
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 through mA Output. If mA Output Process
Variable is set to Volume Flow Rate, the volume flow rate reported through 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 through mA Output.

The two-phase flow parameters control how the transmitter detects and reports two-phase flow (gas in a
liquid process or liquid in a gas process).
Note
Two-phase flow is also referred to as slug flow.
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 twophase flow alerts that are not significant to your process, set Two-Phase Flow Low Limit slightly below
your expected lowest process density.
Configuration and Use Manual 37
Configure process measurement Configuration and Use Manual
June 2022 MMI-20019028
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.
The Two-Phase Flow alert is set immediately. The flow rate will hold the last measured value for the
Timeout time. Then the flow rate will report zero flow. If the density goes back in range, the error clears
immediately.
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.
• 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.

ProLink III Device Tools → Configuration → Process Measurement → Density
Field Communicator Configure → Manual Setup → Measurements → Density → Density Damping
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. For most applications, the default density damping setting is sufficient. 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
Tip
• 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. The valid values for Density
Damping depend on the setting of Update Rate.

Density Cutoff specifies the lowest density value that will be reported as measured. All density values below
this cutoff will be reported as 0.
Procedure
Set Density Cutoff to the value you want to use.
For most applications, the default setting (0.2 g/cm³) is sufficient. The range is 0.0 g/cm³ to 0.5 g/cm³.
Effect of Density Cutoff on volume measurement
Density Cutoff affects liquid volume measurement. If the density value goes below Density Cutoff, the
volume flow rate is reported as 0. Density Cutoff does not affect gas standard volume measurement. Gas
standard volume values are always calculated from the value configured for Standard Gas Density or polled
value if configured for polled base density.

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

data from the sensor.
Procedure
Enter the value you want to use for Temperature Damping.
The default value is 4.8 seconds. For most applications, the default temperature damping setting is sufficient.
The range is 0.0 to 38.4 seconds.
Tip
• A high damping value makes the process variable appear smoother because the reported value changes

Field Communicator • Configure → Manual Setup → Inputs/Outputs → mA Output → mA Output Settings → PV LRV
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.
• OFF-LINE MAINT → OFF-LINE CONFG → IO → CH A → 4 mA
• OFF-LINE MAINT → OFF-LINE CONFG → IO → CH A → 20 mA
• Configure → Manual Setup → Inputs/Outputs → mA Output → mA Output Settings → PV URV
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.
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.
Procedure

• LRVis the value of mA Output Process Variable represented by an output of 4 mA. The default value for
LRV depends on the setting of mA Output Process Variable. Enter LRV in the measurement units that are
configured for mA Output Process Variable.
• URV is the value of mA Output Process Variable represented by an output of 20 mA. The default value for
URV depends on the setting of mA Output Process Variable. Enter URV in the measurement units that are
configured for mA Output Process Variable.
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.

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

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.

Field Communicator Configure → Manual Setup → Inputs/Outputs → mA Output → mA Output Settings → PV Added
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.
Not available
Damping
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.

June 2022 MMI-20019028
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.

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.

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.

HART/RS-485 communications parameters support HART communication with the transmitter's RS-485
terminals.
HART/RS-485 communication parameters include:
• Protocol
• HART Address (Polling Address)
• Parity, Stop Bits, and Baud Rate
Restriction
The transmitter uses the same RS-485 terminals for HART/RS-485, Modbus® RTU, and Modbus ASCII
communications. All RS-485 connection requests must use the same protocol and connection parameters
that are configured in the transmitter.
Procedure
1. Set Protocol to HART RS-485.
2. Set Baud Rate to match the baud rate that will be used by your HART master.
3. Set Parity to match the parity that will be used by your HART master.
4. Set Stop Bits to match the stop bits setting that will be used by your HART master.
5. Set HART Address to a unique value on your network.
Valid address values are between 0 and 15. The default address (0) is typically used unless you are in a
multidrop environment.
Tip
Devices using HART protocol to communicate with the transmitter may use either HART Address or
HART Tag (Software Tag) to identify the transmitter. Configure either or both, as required by your
other HART devices.

8. When you have finished testing or tuning, disable sensor simulation.
7.1.1 Sensor simulation
Sensor simulation allows you to test the system or tune the loop without having to create the test conditions
in your process. When sensor simulation is enabled, the transmitter reports the simulated values for mass
flow, density, and temperature, and takes all appropriate actions. For example, the transmitter might apply a
cutoff, activate an event, or post an alert.
When sensor simulation is enabled, the simulated values are stored in the same memory locations used for
process data from the sensor. The simulated values are then used throughout transmitter functioning. For
example, sensor simulation will affect:
• All mass flow rate, temperature, and density values displayed or reported via outputs or digital
communications
• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and volume inventories
• 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 temperature-compensated
(adjusted for the effect of temperature on the sensor’s flow tubes).
