2 Quick start

Topics covered in this chapter:

• Power up the transmitter

• Check flowmeter status

• Make a startup connection to the transmitter

• Characterize the flowmeter (if required)

• Verify mass flow measurement

• Verify the zero

2.1 Power up the transmitter

The transmitter must be powered up for all configuration and commissioning tasks, or for
process measurement.

1. Ensure that all transmitter and sensor covers and seals are closed.

Quick start

CAUTION!

To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.

2. Turn on the electrical power at the power supply.

The transmitter will automatically perform diagnostic routines. During this period,
Alarm 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 alarm condition is present.

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 is 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.

2.2 Check flowmeter status

Check the flowmeter for any error conditions that require user action or that affect
measurement accuracy.

Configuration and Use Manual 5

Quick start

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, Alarm A009 is active.
This alarm should clear automatically when the power-up sequence is complete.

2. Check the status LED on the transmitter.

Field Communicator Configure > Manual Setup > Characterize

Overview

Characterizing the flowmeter adjusts your transmitter to match the unique traits of the
sensor it is paired with. The characterization parameters (also called calibration
parameters) describe the sensor’s sensitivity to flow, density, and temperature.
Depending on your sensor type, different parameters are required. Values for your sensor
are provided by Micro Motion on the sensor tag or the calibration certificate.

Offline Maintain > Configuration > Calibrate Sensor

• ProLink > Configuration > Flow

• ProLink > Configuration > Density

• ProLink > Configuration > T Series

Tip

If your flowmeter was ordered as a unit, it has already been characterized at the factory. However,
you should still verify the characterization parameters.

Procedure

1. Specify Sensor Type.

• Straight-tube (T-Series)

(5)

• Curved-tube (all sensors except T-Series)

2. Set the flow characterization parameters. Be sure to include all decimal points.

• For straight-tube sensors, set FCF (Flow Cal or Flow Calibration Factor), FTG, and

(5)

FFQ.

• For curved-tube sensors, set Flow Cal (Flow Calibration Factor).

3. Set the density characterization parameters.

• For straight-tube sensors, set D1, D2, DT, DTG, K1, K2, FD, DFQ1, and DFQ2.

(5)

• For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown

as DT.)

(5) Devices with the Chinese-language display do not support T-Series sensors.

2.4.2 Flow calibration parameters (FCF, FT)

Two separate values are used to describe flow calibration: a 6-character FCF value and a 4­character FT value. They are provided on the sensor tag.

Both values contain decimal points. During characterization, these may be entered as two
values or as a single 10-character string. The 10-character string is called either Flowcal or
FCF.

If your sensor tag shows the FCF and the FT values separately and you need to enter a
single value, concatenate the two values to form the single parameter value.

If your sensor tag shows a concatenated Flowcal or FCF value and you need to enter the FCF
and the FT values separately, split the concatenated value:

• FCF = The first 6 characters, including the decimal point

• FT = The last 4 characters, including the decimal point

10 Micro Motion® Model 1700 Transmitters with Analog Outputs

Quick start

Example: Concatenating FCF and FT

FCF = x.xxxx
FT = y.yy
Flow calibration parameter: x.xxxxy.yy

Example: Splitting the concatenated Flowcal or FCF value

Flow calibration parameter: x.xxxxy.yy
FCF = x.xxxx
FT = y.yy

2.4.3 Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)

Density calibration parameters are typically on the sensor tag and the calibration
certificate.

If your sensor tag does not show a D1 or D2 value:

• For D1, enter the Dens A or D1 value from the calibration certificate. This value is the

line-condition density of the low-density calibration fluid. Micro Motion uses air. If
you cannot find a Dens A or D1 value, enter 0.001 g/cm3.

• For D2, enter the Dens B or D2 value from the calibration certificate. This value is the

line-condition density of the high-density calibration fluid. Micro Motion uses water.
If you cannot find a Dens B or D2 value, enter 0.998 g/cm3.

If your sensor tag does not show a K1 or K2 value:

• For K1, enter the first 5 digits of the density calibration factor. In the sample tag, this

value is shown as 12500.

• For K2, enter the second 5 digits of the density calibration factor. In the sample tag,

this value is shown as 14286.

If your sensor does not show an FD value, contact Micro Motion customer service.

If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density
calibration factor. In the sample tag, this value is shown as 4.44.

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.

• Read the value for Mass Flow Rate on the transmitter display.

• Connect to the transmitter with ProLink II and read the value for Mass Flow Rate in the

Process Variables window (ProLink > Process Variables).

• Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in

the Process Variables panel.

Configuration and Use Manual 11

Quick start

• Connect to the transmitter with the Field Communicator and read the value for Mass

Flow Rate in the Process Variables menu (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. See

Section 10.3.

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.

2.6.1 Verify the zero using ProLink II

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.

Important

In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless
one of the following is true:

• The zero is required by site procedures.

• The stored zero value fails the zero verification procedure.

Prerequisites

ProLink II v2.94 or later

Important

Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem,
then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a low­severity alarm is active.

Procedure

1. Prepare the flowmeter:

a. Allow the flowmeter to warm up for at least 20 minutes after applying power.

12 Micro Motion® Model 1700 Transmitters with Analog Outputs

Quick start

b. Run the process fluid through the sensor until the sensor temperature reaches

the normal process operating temperature.

c. Stop flow through the sensor by shutting the downstream valve, and then the

upstream valve if available.

d. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is

completely full of process fluid.

2. Choose ProLink > Calibration > Zero Verification and Calibration > Verify Zero and wait until

the procedure completes.

3. 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. Repeat the zero verification procedure.

d. If it fails again, zero the flowmeter.

For instructions on zeroing the flowmeter, see Zero the flowmeter.

Postrequisites

Restore normal flow through the sensor by opening the valves.

2.6.2 Verify the zero using ProLink III

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.

Important

In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless
one of the following is true:

• The zero is required by site procedures.

• The stored zero value fails the zero verification procedure.

Prerequisites

ProLink III v1.0 with Patch Build 31, or a later release

Important

Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem,
then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a low­severity alarm is active.

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 proce-

dure. 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 ap-

plied. An adaptive damping value is applied only when the mass flow rate changes dra­matically over a very short interval. Unit = configured mass flow measurement unit.

Zero Stability A laboratory-derived value used to calculate the expected accuracy for a sensor. Under

laboratory conditions at zero flow, the average flow rate is expected to fall within the
range defined by the Zero Stability value (0 ± Zero Stability). Each sensor size and model
has a unique Zero Stability value. Statistically, 95% of all data points should fall within the
range defined by the Zero Stability value.

Zero Calibration The procedure used to determine the zero value.

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 (standard option), you can
use the standard display to select an existing special measurement unit, and to view process data
using the special measurement unit.

Offline Maintain > Configuration > Units > Special Mass Flow

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

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

4.1.2 Configure Flow Damping

display

ProLink II ProLink > Configuration > Flow > Flow Damp

ProLink III Device Tools > Configuration > Process Measurement > Flow

Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Damping

Offline Maintain > Configuration > Damping > Mass 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 reported process variable. At the end of the interval, the reported process variable
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.

Core processor type Update Rate setting Flow Damping range

Standard Normal 0 to 51.2 seconds

Special 0 to 10.24 seconds

Enhanced Not applicable 0 to 51.2 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.

• The combination of a high damping value and rapid, large changes in flow rate can result in

increased measurement error.

24 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.

• For gas applications, Micro Motion recommends setting Flow Damping to 2.56 or higher.

The value you enter is automatically rounded down to the nearest valid value. Valid
damping values are shown in the following table.

Valid values for Flow DampingTable 4-2:

Core processor type Update Rate setting Valid damping values

Standard Normal 0, 0.2, 0.4, 0.8, ... 51.2

Special 0, 0.04, 0.08, 0.16, ... 10.24

Enhanced Not applicable 0, 0.2, 0.4, 0.8, ... 51.2

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 Added Damping

In some circumstances, both Flow Damping and Added Damping are applied to the reported
mass flow value.

Flow Damping controls the rate of change in flow process variables. Added 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 Added Damping are set to non-zero values, flow
damping is applied first, and the added damping calculation is applied to the result of the
first calculation.

Configure process measurement

Overview

Mass Flow Cutoff specifies the lowest mass flow rate that will be reported as measured. All
mass flow rates below this cutoff will be reported as 0.

Procedure

Set Mass Flow Cutoff to the value you want to use.

The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the
factory. The recommended setting is 0.05% of the sensor's rated maximum flow rate or a
value below the highest expected flow rate. Do not set Mass Flow Cutoff to 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.

Interaction between Mass Flow Cutoff and AO Cutoff

Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as
measured. AO 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).

AO Cutoff affects only mass flow values reported via the mA output.

Example: Cutoff interaction with AO Cutoff lower than Mass Flow Cutoff

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, mass flow will be reported as 0, and 0
will be used in all internal processing.

Example: Cutoff interaction with AO Cutoff higher than Mass Flow Cutoff

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:

26 Micro Motion® Model 1700 Transmitters with Analog Outputs

Configure process measurement

• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:

- The mA output will report zero flow.

- The frequency output will report the actual flow rate, and the actual flow rate will

be used in all internal processing.

• If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0

will be used in all internal processing.

4.2 Configure volume flow measurement for liquid applications

Overview

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.
The upper limit is the sensor’s flow calibration factor, in units of l/sec, multiplied by 0.2.

Interaction between Volume Flow Cutoff and AO Cutoff

Volume Flow Cutoff defines the lowest liquid volume flow value that the transmitter will

report as measured. AO 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).

AO Cutoff affects only flow values reported via the mA output.

Example: Cutoff interaction with AO Cutoff lower than Volume Flow Cutoff

Configuration:

• mA Output Process Variable: Volume Flow Rate

• Frequency Output Process Variable: Volume Flow Rate

Configuration and Use Manual 31

Configure process measurement

• 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 AO 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:

• If the volume flow rate drops below 10 l/sec, both outputs will report zero flow, and

- 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.

0 will be used in all internal processing.

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.

Not available

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/y

4. Enter the Gas Standard Volume Flow 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 SCFM.

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 = 1/1000 = 0.001

4. Set Gas Standard Volume Flow Conversion Factor to 0.001.

5. Set Gas Standard Volume Flow Label to KSCFM.

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 AO Cutoff

Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume flow value that the

transmitter will report as measured. AO 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.

Configuration and Use Manual 37

Configure process measurement

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).

AO Cutoff affects only flow values reported via the mA output.

Example: Cutoff interaction with AO Cutoff lower than Gas Standard Volume Flow Cutoff

Configuration:

• mA Output Process Variable for the primary mA output: Gas Standard Volume Flow Rate

• Frequency Output Process Variable: Gas Standard Volume Flow Rate

• AO Cutoff for the primary mA output: 10 SLPM (standard liters per minute)

• Gas Standard Volume Flow Cutoff: 15 SLPM

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.

Example: Cutoff interaction with AO Cutoff higher than Gas Standard Volume Flow Cutoff

Configuration:

• mA Output Process Variable for the primary mA output: Gas Standard Volume Flow Rate

• Frequency Output Process Variable: Gas Standard Volume Flow Rate

• AO Cutoff for the primary mA output: 15 SLPM (standard liters per minute)

• Gas Standard Volume Flow Cutoff: 10 SLPM

Result:

• If the gas standard volume flow rate drops below 15 SLPM but not below 10 SLPM:

- The primary 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 gas standard volume flow rate drops below 10 SLPM, both outputs will report

zero flow, and 0 will be used in all internal processing.

38 Micro Motion® Model 1700 Transmitters with Analog Outputs

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.

Procedure

Set Flow Direction to the value you want to use.

Configure process measurement

Overview

The slug flow parameters control how the transmitter detects and reports two-phase flow
(gas in a liquid process or liquid in a gas process).

Procedure

1. Set Slug Low Limit to the lowest density value that is considered normal in your
process.

Values below this will cause the transmitter to perform the configured slug flow
action. Typically, this value is the lowest density value in the normal range of your
process.

Tip

Gas entrainment can cause your process density to drop temporarily. To reduce the
occurrence of slug flow alarms that are not significant to your process, set Slug Low Limit
slightly below your expected lowest process density.

You must enter Slug Low Limit in g/cm3, even if you configured another unit for
density measurement.

The default value for Slug Low Limit is 0.0 g/cm3. The range is 0.0 to 10.0 g/cm3.

2. Set Slug High Limit to the highest density value that is considered normal in your
process.

Values above this will cause the transmitter to perform the configured slug flow
action. Typically, this value is the highest density value in the normal range of your
process.

Tip

To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug
High Limit slightly above your expected highest process density.

You must enter Slug High Limit in g/cm3, even if you configured another unit for
density measurement.

The default value for Slug High Limit is 5.0 g/cm3. The range is 0.0 to 10.0 g/cm3.

3. Set Slug Duration to the number of seconds that the transmitter will wait for a slug
flow condition to clear before performing the configured slug flow action.

The default value for Slug Duration is 0.0 seconds. The range is 0.0 to 60.0 seconds.

Slug flow detection and reporting

Slug flow is typically used as an indicator of two-phase flow (gas in a liquid process or liquid
in a gas process). Two-phase flow can cause a variety of process control issues. By
configuring the slug flow parameters appropriately for your application, you can detect
process conditions that require correction.

46 Micro Motion® Model 1700 Transmitters with Analog Outputs

Configure process measurement

Tip

To decrease the occurrence of slug flow alarms, lower Slug Low Limit or raise Slug High Limit.

A slug flow condition occurs whenever the measured density goes below Slug Low Limit or
above Slug High Limit. If this occurs:

• A slug flow alarm is posted to the active alarm log.

• All outputs that are configured to represent flow rate hold their last “pre-slug flow”

value for the configured Slug Duration.

If the slug flow condition clears before Slug Duration expires:

• Outputs that represent flow rate revert to reporting actual flow.

• The slug flow alarm is deactivated, but remains in the active alarm log until it is

acknowledged.

If the slug flow condition does not clear before Slug Duration expires, the outputs that
represent flow rate report a flow rate of 0.

If Slug Duration is set to 0.0 seconds, the outputs that represent flow rate will report a flow
rate of 0 as soon as slug flow is detected.

4.5.3 Configure Density Damping

Display (standard) Not available

Chinese-language
display

ProLink II ProLink > Configuration > Density > Density Damping

ProLink III Device Tools > Configuration > Process Measurement > Density

Field Communicator Configure > Manual Setup > Measurements > Density > Density 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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value.

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:

Offline Maintain > Configuration > Damping > Density Damping

Core processor type Update Rate setting Density Damping range

Standard Normal 0 to 51.2 seconds

Special 0 to 10.24 seconds

Configuration and Use Manual 47

Configure process measurement

Core processor type Update Rate setting Density Damping range

Enhanced Not applicable 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.

• 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 automaticaly rounded down to the nearest valid value. The valid
values for Density Damping depend on the setting of Update Rate.

Valid values for Density DampingTable 4-11:

Core processor type Update Rate setting Valid damping values

Standard Normal 0, 0.2, 0.4, 0.8, ... 51.2

Special 0, 0.04, 0.08, 0.16, ... 10.24

Enhanced Not applicable 0, 0.04, 0.08, 0.16, ... 40.96

Effect of Density Damping on volume measurement

Density Damping affects liquid volume measurement. Liquid volume values are calculated

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

Interaction between Density Damping and Added Damping

In some circumstances, both Density Damping and Added Damping are applied to the reported
density value.

Density Damping controls the rate of change in the density process variable. Added Damping
controls the rate of change reported via the mA output. If mA Output Process Variable is set to
Density, and both Density Damping and Added Damping are set to non-zero values, density
damping is applied first, and the added damping calculation is applied to the result of the
first calculation.

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.

4.6 Configure temperature measurement

Effect of Temperature Damping on process measurement

Temperature Damping affects the response speed for temperature compensation with

fluctuating temperatures. Temperature compensation adjusts the process measurement
to compensate for the effect of temperature on the sensor tube.

Configuration and Use Manual 51

Configure process measurement

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.micromotion.com. If you are
uncertain about implementing pressure compensation, contact Micro Motion customer service.

4.7.1 Configure pressure compensation using ProLink II

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

unavailable, use 20 PSI.

Procedure

1. Choose View > Preferences and ensure that Enable External Pressure Compensation is
checked.

2. Choose ProLink > Configuration > Pressure.

3. 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.

4. 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.

Example:

If the density factor is 0.000006 g/cm3/PSI, enter −0.000006 g/cm3/PSI.

5. Enter Cal 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.

80 Micro Motion® Model 1700 Transmitters with Analog Outputs

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.

The mA output parameters include:

• mA Output Process Variable

• Lower Range Value (LRV) and Upper Range Value (URV)

• AO Cutoff

• Added Damping

• AO Fault Action and AO Fault Value

Integrate the meter with the control system

Important

Whenever you change an mA output parameter, verify all other mA output parameters before
returning the flowmeter to service. In some situations, the transmitter automatically loads a set of
stored values, and these values may not be appropriate for your application.

Integrate the meter with the control system

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. For
example, if you set mA Output Process Variable to Mass Flow Rate and change the LRV and URV, then you
set mA Output Process Variable to Density, and finally you change mA Output Process Variable back to Mass
Flow Rate, LRV and URV for Mass Flow Rate reset to the values that you configured. In earlier versions of
the transmitter software, LRV and URV reset to the factory default values.

Procedure

Set LRV and URV as desired.

• LRV is 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.

Tips

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 range of the bit precision of the D/A converter.

Note

You can set URV below LRV. For example, you can set URV to 50 and LRV to 100.

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 alarm.

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.

ProLink III Device Tools > Configuration > I/O > Outputs > mA Output

Field Communicator Configure > Manual Setup > Inputs/Outputs > mA Output > mA Output Settings > PV MAO Cutoff

Not available

Overview

AO Cutoff (Analog Output Cutoff) specifies the lowest mass flow rate, volume flow rate, or
gas standard volume flow rate that will be reported through the mA output. Any flow rates
below AO Cutoff will be reported as 0.

Restriction

AO Cutoff is applied only if mA Output Process Variable is set to Mass Flow Rate, Volume Flow Rate, or Gas
Standard Volume Flow Rate. If mA Output Process Variable is set to a different process variable, AO Cutoff is

not configurable, and the transmitter does not implement the AO cutoff function.

Procedure

Set AO Cutoff as desired.

The default value for AO Cutoff is 0.0 g/sec.

Tip

For most applications, the default value of AO Cutoff should be used. Contact Micro Motion 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.

84 Micro Motion® Model 1700 Transmitters with Analog Outputs

Integrate the meter with the control system

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.

ProLink II ProLink > Configuration > Analog Output > Primary Output > AO Added Damp

ProLink III Device Tools > Configuration > I/O > Outputs > mA Output

Field Communicator Configure > Manual Setup > Inputs/Outputs > mA Output > mA Output Settings > PV Added Damping

Overview

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 reported process variable. At the end of the interval, the reported process variable
will reflect 63% of the change in the actual measured value. Added Damping controls the
amount of damping that will be applied to the mA output. It 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., the frequency output or digital
communications), or the value of the process variable used in calculations.

Not available

Configuration and Use Manual 85

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.

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 Added Damping and process variable damping

When mA Output Process Variable is set to a flow variable, density, or temperature, Added
Damping interacts with Flow Damping, Density Damping, or Temperature Damping. If multiple

damping parameters are applicable, the effect of damping the process variable is
calculated first, and the added damping calculation is applied to the result of that
calculation.

Example: Damping interaction

Configuration:

• Flow Damping = 1 second

• mA Output Process Variable = Mass Flow Rate

• Added 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.

CAUTION!

If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action to None. If you do not, the output will not report actual process data,
and this may result in measurement errors or unintended consequences for your process.

Restriction

If 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.

6.3 Configure the frequency output

The frequency output is used to report a process variable. The frequency output
parameters control how the process variable is reported. Your transmitter may have zero
or one frequency output: Channel B can be configured as a frequency output or a discrete
output.

The frequency output parameters include:

• Frequency Output Polarity

• Frequency Output Scaling Method

• Frequency Output Maximum Pulse Width

• Frequency Output Fault Action and Frequency Output Fault Value

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 a frequency output parameter, verify all other frequency output parameters
before returning the flowmeter to service. In some situations, the transmitter automatically loads a
set of stored values, and these values may not be appropriate for your application.

Option Description

Pulses/Unit A user-specified number of pulses represents one flow unit

Units/Pulse A pulse represents a user-specified number of flow units

2. Set additional required parameters.

• If you set Frequency Output Scaling Method to Frequency=Flow, set Rate Factor and

Frequency Factor.

• If you set Frequency Output Scaling Method to Pulses/Unit, define the number of pulses

that will represent one flow unit.

• If you set Frequency Output Scaling Method to Units/Pulse, define the number of units

that each pulse will indicate.

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.

Above this rate, the transmitter will report A110: Frequency Output Saturated.

Frequency
Factor

A value calculated as follows:

FrequencyFactor = x N

RateFactor

T

where:

T Factor to convert selected time base to seconds

N Number of pulses per flow unit, as configured in the receiving device

The resulting Frequency Factor must be within the range of the frequency output (0 to
10,000 Hz):

• If Frequency Factor is less than1 Hz,reconfigure the receiving device for a higher

pulses/unit setting.

• If Frequency Factor is greater than 10,000 Hz, reconfigure the receiving device for a

lower pulses/unit setting.

Tip

If Frequency Output Scale Method is set to Frequency=Flow, and Frequency Output Maximum Pulse Width is set
to a non-zero value, Micro Motion recommends setting Frequency Factor to a value below 200 Hz.

Example: Configure Frequency=Flow

You want the frequency output to report all flow rates up to 2000 kg/min.

Overview

Frequency Output Maximum Pulse Width is used to ensure that the duration of the ON signal is
great enough for your frequency receiving device to detect.

The ON signal may be the high voltage or 0.0 V, depending on Frequency Output Polarity.

Procedure

Set Frequency Output Maximum Pulse Width as desired.

Configuration and Use Manual 91

Integrate the meter with the control system

The default value is 277 milliseconds. You can set Frequency Output Maximum Pulse Width to
0 milliseconds or to a value between 0.5 milliseconds and 277.5 milliseconds. The
transmitter automatically adjusts the value to the nearest valid value.

Tip

Micro Motion recommends leaving Frequency Output Maximum Pulse Width at the default value. Contact
Micro Motion customer service before changing Frequency Output Maximum Pulse Width.

Fault Level

Overview

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 Last Measured Value 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.

None (default) Tracks data for the assigned process variable; no fault action

CAUTION!

If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action to None. If you do not, the output will not report actual process data,
and this may result in measurement errors or unintended consequences for your process.

Restriction

If 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.

6.4 Configure the discrete output

The discrete output is used to report specific flowmeter 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.

The discrete output parameters include:

• Discrete Output Source

• Discrete Output Polarity

• Discrete Output Fault Action

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 flowmeter to service. In some situations, the transmitter automatically loads a
set of stored values, and these values may not be appropriate for your application.
