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 7
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.
Transmitter status reported by status LEDTable 2-1:

and have been acknowledged.
One or more high-severity alarms are active and have not been acknowledged.
Continue with configuration or process meas­urement. If you choose, you can acknowledge the alarms.
A low-severity alarm condition does not affect measurement accuracy or output behavior. You can continue with configuration or proc­ess measurement. If you choose, you can iden­tify and resolve the alarm condition.
A low-severity alarm condition does not affect measurement accuracy or output behavior. You can continue with configuration or proc­ess measurement. If you choose, you can iden­tify and resolve the alarm condition. You may also acknowledge the alarm.
A high-severity alarm condition affects meas­urement accuracy and output behavior. Re­solve the alarm condition before continuing.

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.
Communications tool Connection type to use Instructions
ProLink II HART/RS-485 Appendix B
ProLink III HART/RS-485 Appendix C
Field Communicator HART Appendix D
Postrequisites
(Optional) Change the communications parameters to site-specific values.
To change the communications parameters using ProLink II:
• To change the protocol, baud rate, parity, or stop bits, choose ProLink > Configuration >
RS-485.
• To change the address, choose ProLink > Configuration > Device.
To change the communications parameters using ProLink III, choose Device Tools > Configuration > Communications.
To change the communications parameters using the Field Communicator, choose On-Line Menu > Configure > Manual Setup > Inputs/Outputs > Communications.
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.

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.
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
Specify Sensor Type.
1.
• Straight-tube (T-Series)
• 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 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.
• For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown
as DT.)
2.4.1 Sources and formats for characterization parameters
Different sensor tags display characterization parameters differently. On older sensors, the sensor tag may not contain all the required parameters.
Sample sensor tags
Sample sensor tags are shown in the following illustrations:
10 Micro Motion® Model 2700 Transmitters with Analog Outputs
• Older curved-tube sensors (all sensors except T-Series): see Figure 2-1
• Newer curved-tube sensors (all sensors except T-Series): see Figure 2-2

Density calibration parameters (D1, D2, K1, K2, FD, DT, TC)
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 (see Figure 2-1).
• For K2, enter the second 5 digits of the density calibration factor. In the sample tag,
this value is shown as 14286 (see Figure 2-1).
If your sensor does not show an FD value, contact Micro Motion customer service.
12 Micro Motion® Model 2700 Transmitters with Analog Outputs
Quick start
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 (see Figure 2-1).
Flow calibration parameters (FCF, FT)
Two separate values are used to describe flow calibration: a 6-character FCF value and a 4­character FT value. 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
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

2.5 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.
• 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.
Configuration and Use Manual 13
Quick start
• Review the troubleshooting suggestions for flow measurement issues. See
Section 12.3.

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.
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.
14 Micro Motion® Model 2700 Transmitters with Analog Outputs
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 Section 11.3.
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.

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.
Procedure
1. Prepare the flowmeter:
a. Allow the flowmeter to warm up for at least 20 minutes after applying power.
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 Device Tools > Device Calibration > Zero Verification and Calibration > Verify Zero and wait until the procedure completes.
Configuration and Use Manual 15

2.6.3 Terminology used with zero verification and zero calibration
Terminology used with zero verification and zero calibrationTable 2-2:
Term Definition
Zero In general, the offset required to synchronize the left pickoff and the right pickoff under
conditions of zero flow. Unit = microseconds.
Factory Zero The zero value obtained at the factory, under laboratory conditions.
Field Zero The zero value obtained by performing a zero calibration outside the factory.
Prior Zero The zero value stored in the transmitter at the time a field zero calibration is begun. May
be the factory zero or a previous field zero.
Manual Zero The zero value stored in the transmitter, typically obtained from a zero calibration 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.
Zero Time The time period over which the Zero Calibration procedure is performed. Unit = seconds.
Field Verification Zero A 3-minute running average of the Live Zero value, calculated by the transmitter. Unit =
configured mass flow measurement unit.
Zero Verification A procedure used to evaluate the stored zero and determine whether or not a field zero
can improve measurement accuracy.

Overview
A special measurement unit is a user-defined unit of measure that allows you to report process data, totalizer data, and inventory data in a unit that is not available in the transmitter. A special measurement unit is calculated from an existing measurement unit using a conversion factor.
Note
Although you cannot define a special measurement unit using the display, you can use the display to select an existing special measurement unit, and to view process data using the special measurement unit.
Procedure
Specify Base Mass Unit.
1.
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
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 Manual 25
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.
4.1.2 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
Not available
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
Standard
Enhanced Not applicable 0 to 51.2 seconds
Update Rate setting Flow Damping range
Normal
Special
0 to 51.2 seconds
0 to 10.24 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.
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
26 Micro Motion® Model 2700 Transmitters with Analog Outputs
Configure process measurement
• In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
• 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
Standard
Enhanced Not applicable 0, 0.2, 0.4, 0.8, ... 51.2
Update Rate setting
Normal
Special
Valid damping values
0, 0.2, 0.4, 0.8, ... 51.2
0, 0.04, 0.08, 0.16, ... 10.24
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.
4.1.3 Configure Mass Flow Cutoff
Display
ProLink II ProLink > Configuration > Flow > Mass Flow Cutoff
ProLink III Device 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.
Configuration and Use Manual 27
Not available
Configure process measurement
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:
• If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
- The mA output will report zero flow.
28 Micro Motion® Model 2700 Transmitters with Analog Outputs
Configure process measurement
- 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.

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
Specify Base Volume Unit.
1.
Base Volume Unit is the existing 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 Volume Flow Conversion Factor as follows:
a. x base units = y special units
b. Volume Flow Conversion Factor = x/y
4. Enter Volume Flow Conversion Factor.
5. Set Volume Flow Label to the name you want to use for the volume flow unit.
6. Set Volume Total Label to the name you want to use for the volume total and 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 volume flow
You want to measure volume flow in pints per second (pints/sec).
1. Set Base Volume Unit to Gallons (gal).
2. Set Base Time Unit to Seconds (sec).
3. Calculate the conversion factor:
32 Micro Motion® Model 2700 Transmitters with Analog Outputs
a. 1 gal/sec = 8 pints/sec
b. Volume Flow Conversion Factor = 1/8 = 0.1250
4. Set Volume Flow Conversion Factor to 0.1250.
5. Set Volume Flow Label to pints/sec.
6. Set Volume Total Label to pints.

Display
ProLink II ProLink > Configuration > Flow > Vol Flow Cutoff
ProLink III Device Tools > Configuration > Process Measurement > Flow
Field Communicator Configure > Manual Setup > Measurements > Flow > Volume Flow Cutoff
Not available
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
• AO Cutoff: 10 l/sec
• Volume Flow Cutoff: 15 l/sec
Configuration and Use Manual 33
Configure process measurement
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
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.
Configuration and Use Manual 47
Configure process measurement
3. Set Slug Duration to the number of seconds that the transmitter will wait for a slug
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.
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:
The default value for Slug High Limit is 5.0 g/cm3. The range is 0.0 to 10.0 g/cm3.
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.
• 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.

Configure process measurement
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:
Core processor type
Standard
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.

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.

Configure process 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.

Overview
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.
The default value for Density Cutoff is 0.2 g/cm3. 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.

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
Enter the value you want to use for Temperature Damping.
The default value is 4.8 seconds. The range is 0.0 to 76.8 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. Valid values for Temperature Damping are 0, 0.6, 1.2, 2.4, 4.8, … 76.8.
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.
Temperature Damping affects petroleum measurement process variables only if the transmitter is configured to use temperature data from the sensor. If an external temperature value is used for petroleum measurement, Temperature Damping does not affect petroleum measurement process variables.
Temperature Damping affects concentration measurement process variables only if the transmitter is configured to use temperature data from the sensor. If an external temperature value is used for concentration measurement, Temperature Damping does not affect concentration measurement process variables.

Overview
Calculation Speed is used to apply a different algorithm to the calculation of process variables from the raw process data. Calculation Speed = Special produces faster and “noisier” response to changes in the process.
In ProLink II, Calculation Speed is called Response Time.
Restriction
Calculation Speed is available only on systems with the enhanced core processor.
Tip
You can use Calculation Speed = Special with either setting of Update Rate. The parameters control different aspects of flowmeter processing.
Procedure
Set Calculation Speed as desired.
Option Description
Normal
Special
Transmitter calculates process variables at the standard speed.
Transmitter calculates process variables at a faster speed.

5.5 Configure alarm handling

The alarm handling parameters control the transmitter’s response to process and device conditions.
Alarm handling parameters include:
Fault Timeout

Overview
Fault Timeout controls the delay before fault actions are performed.
Restriction
Fault Timeout is applied only to the following alarms (listed by Status Alarm Code): A003, A004, A005, A008, A016, A017, A033. For all other alarms, fault actions are performed as soon as the alarm is detected.
Procedure
Set Fault Timeout as desired.
The default value is 0 seconds. The range is 0 to 60 seconds.
If you set Fault Timeout to 0, fault actions are performed as soon as the alarm condition is detected.
The fault timeout period begins when the transmitter detects an alarm condition. During the fault timeout period, the transmitter continues to report its last valid measurements.
If the fault timeout period expires while the alarm is still active, the fault actions are performed. If the alarm condition clears before the fault timeout expires, no fault actions are performed.
Tip
ProLink II allows you to set Fault Timeout in two locations. However, there is only one parameter, and the same setting is applied to all outputs.

Overview
Use Status Alarm Severity to control the fault actions that the transmitter performs when it detects an alarm condition.
Restrictions
• For some alarms, Status Alarm Severity is not configurable.
• For some alarms, Status Alarm Severity can be set only to two of the three options.
Tip
Micro Motion recommends using the default settings for Status Alarm Severity unless you have a specific requirement to change them.
Procedure
1.
Select a status alarm.
2. For the selected status alarm, set Status Alarm Severity as desired.
Option Description

Actions when fault is detected:
• The alarm is posted to the Alert List.
• Outputs go to the configured fault action (after Fault Timeout has expired, if
applicable).
• Digital communications go to the configured fault action (after Fault Timeout
has expired, if applicable).
• The status LED (if available) changes to red or yellow (depending on alarm se-
verity).
Actions when alarm clears:
• Outputs return to normal behavior.
• Digital communications return to normal behavior.
• The status LED (if available) returns to green and may or may not flash.
