MMI-20019048 May 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.

measurement accuracy and output behavior. Resolve the alert condition before continuing.

A high-severity alert condition affects measurement accuracy and output behavior. Resolve the alert condition before continuing. Acknowledge the alert if you choose.

If Status LED Blinking is disabled, all LEDs will show a solid color rather than flashing.

2.3 Make a startup connection to the transmitter

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

Procedure

Identify the connection type to use, and follow the instructions for that connection type in the appropriate appendix.

2.4 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.

2.5 Verify the zero

Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy.

The zero verification procedure analyzes the Live Zero value under conditions of zero flow, and compares it to the Zero Stability range for the sensor. If the average Live Zero value is within a reasonable range, the zero value stored in the transmitter is valid. Performing a field calibration will not improve measurement accuracy.

Important

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

• The zero is required by site procedures.

• The stored zero value fails the zero verification procedure.

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.

ProLink III Device Tools → Configuration → Process Measurement → Flow

Field Communicator Configure → Manual Setup → Measurements → Flow → Mass Flow Unit

Mass Flow Measurement Unit specifies the unit of measure that will be used for the mass flow rate. The unit used for mass total and mass inventory is derived from this unit.

You can configure the mA and Frequency Outputs independently. For example, you can configure the mA Output for mass flow and the Frequency Output for liquid volume or gas standard volume. If the same process variable is assigned to both the mA and Frequency Outputs, then any selected measurement unit, (mass, volume or gas standard volume), is automatically applied to both outputs.

Procedure

Set Mass Flow Measurement Unit to the unit you want to use.

The default setting for Mass Flow Measurement Unit is g/sec (grams per second).

Tip

If the measurement unit you want to use is not available, you can define a special measurement unit.

Options for Mass Flow Measurement Unit

The transmitter provides a standard set of measurement units for Mass Flow Measurement Unit, plus one user-defined special measurement unit. Different communications tools may use different labels for the units.

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.

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:

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 Not available

ProLink III Device Tools → Configuration → Process Measurement → Flow

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

Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies the time period (in seconds) over which the transmitter will spread changes in the process variable. At the end of the interval, the internal value will reflect 63% of the change in the actual measured value.

Procedure

Set Flow Damping to the value you want to use.

The default value is 0.8 seconds. The range depends on the core processor type and the setting of Update Rate, as shown in the following table.

Update Rate setting

Normal 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.

— 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.

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.

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

Configuration:

• Configure → Manual Setup → Measurements → Density → Slug Duration

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 41

Configure process measurement Configuration and Use Manual

May 2022 MMI-20019048

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.

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.

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

When the mA Output is configured to report density, both Density Damping and Added Damping are applied to the reported density value.

Density Damping controls the rate of change in the value of the process variable in transmitter memory. 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. This value is reported over the mA Output.

4.5.4 Configure Density Cutoff

Display Not available

ProLink III Device Tools → Configuration → Process Measurement → Density

Field Communicator Configure → Manual Setup → Measurements → Density → Density Cutoff

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.

4.8 Set up concentration measurement

This section guides you through loading and setting up a concentration matrix used for measurement. It does not cover building a concentration matrix.

The concentration measurement application calculates concentration data from process temperature and density. Micro Motion provides a set of concentration matrices that provide the reference data for several standard industry applications and process fluids. If desired, you can build a custom matrix for your process fluid, or purchase a custom matrix from Micro Motion.

Note

Concentration matrices can be made available on your transmitter either by loading an existing matrix from a file or by building a new matrix. Up to 6 matrices can be available on your transmitter, but only 1 can be used for measurement at any given time. For detailed information on building a matrix, see the Micro Motion Enhanced Density Application Manual.

Prerequisites

Before you can configure concentration measurement:

• The concentration measurement application must be purchased on your transmitter.

• The concentration matrix you want to use must be available on your transmitter, or it must be available as

a file on your computer.

• You must know the derived variable that your matrix is designed for.

• You must know the density unit used by your matrix.

• You must know the temperature unit used by your matrix.

• The concentration measurement application must be unlocked.

4.8.1 Configure concentration measurement using ProLink III

Procedure

1. Choose Device Tools → Configuration → Process Measurement → Density and set Density Unit to

the density unit used by your matrix.

f) Do not change Reference Temperature or Curve Fit Maximum Order.

g) If you changed any matrix data, click Apply.

7. Set up extrapolation alarms.

Each concentration matrix is built for a specific density range and a specific temperature range. If process density or process temperature goes outside the range, the transmitter will extrapolate concentration values. However, extrapolation may affect accuracy. Extrapolation alarms are used to notify the operator that extrapolation is occurring.

a) If necessary, set Matrix Being Configured to the matrix you want to view, and select Change

Matrix.

b) Set Extrapolation Alarm Limit to the point, in percent, at which an extrapolation alarm will be

posted.

c) Enable or disable the high and low limit alarms for temperature and density, as desired, and

select Apply.

Restriction

The high and low limit alarms require the enhanced core processor.

Example

If Extrapolation Alarm Limit is set to 5%, High Extrapolation Limit (Temperature) is enabled, and the matrix is built for a temperature range of 40 °F (4.4 °C) to 80 °F (26.7 °C), an extrapolation alarm will be posted if process temperature goes above 82 °F (27.8 °C).

4.9 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 Emerson.com. If you are uncertain about implementing pressure compensation, contact customer service.

Prerequisites

You will need the flow factor, density factor, and calibration pressure values for your sensor.

• For the flow factor and density factor, see the product data sheet for your sensor.

• For the calibration pressure, see the calibration sheet for your sensor. If the data is unavailable, use 20 PSI.

ProLink III Device Tools → Configuration → I/O → Outputs

Field communicator Configure → Manual Setup → Inputs/Outputs → Channels → Channel B

You can configure Channel B on your transmitter to operate as a Frequency Output or a Discrete Output. The channel configuration must match the wiring at the transmitter terminals.

Prerequisites

To avoid causing process errors:

• Configure the channels before configuring the outputs.

• Before changing the channel configuration, ensure that all control loops affected by the channel are under

manual control.

Procedure

Set Channel B as desired.

Option

Frequency Output Channel B will operate as a Frequency Output.

Discrete Output Channel B will operate as a Discrete Output.

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.

Description

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 two mA Outputs: Channel A and Channel C.

Important

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

(URV)

Display

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

Field Communicator

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/C → 4 mA

• Configure → Manual Setup → Inputs/Outputs → mA Output X → mA Output Settings → PV/SV 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.

86 Micro Motion 2700 Transmitters with Intrinsically Safe Outputs

Configuration and Use Manual Integrate the meter with the control system

MMI-20019048 May 2022

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.

• 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.

Cutoff

• Configure → Manual Setup → Inputs/Outputs → mA Output 2 → mA Output Settings → MAO

Cutoff

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

volume flow rate that will be reported through the mA Output. Any flow rates below AO Cutoff will be reported as 0.

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 values for AO Cutoff are as follows:

• Primary mA Output: 0.0 g/sec

• Secondary mA Output: Not-A-Number

Tip

For most applications, the default value of AO Cutoff should be used. Contact customer service before changing AO Cutoff.

Interaction between AO Cutoff and process variable cutoffs

When mA Output Process Variable is set to a flow variable (for example, mass flow rate or volume flow rate), AO Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The transmitter puts the cutoff into effect

at the highest flow rate at which a cutoff is applicable.

Example: Cutoff interaction

Configuration:

• mA Output Process Variable = Mass Flow Rate

• Frequency Output Process Variable = Mass Flow Rate

• AO Cutoff = 10 g/sec

• Mass Flow Cutoff = 15 g/sec

Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will report zero flow.

Example: Cutoff interaction

Configuration:

• mA Output Process Variable = Mass Flow Rate

• Frequency Output Process Variable = Mass Flow Rate

• AO Cutoff = 15 g/sec

• Mass Flow Cutoff = 10 g/sec

Result:

• If the mass flow rate drops below 15 g/sec but not below 10 g/sec: — The mA Output will report zero flow.

— The Frequency Output will report the actual flow rate.

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

Field Communicator • Configure → Manual Setup → Inputs/Outputs → mA Output 1 → mA Output Settings → PV Added

Damping

• Configure → Manual Setup → Inputs/Outputs → mA Output 2 → mA Output Settings → SV Added

Damping

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

Added Damping affects the reporting of mA Output Process Variable through the mA Output only. It does not affect the reporting of that process variable via any other method (e.g., a Frequency Output or digital communications), or the value of the process variable used in calculations.

Note

Added Damping is not applied if the mA Output is fixed (for example, during loop testing) or if the mA Output is reporting a fault. Added Damping is applied while sensor simulation is active.

Procedure

Set Added Damping to the desired value.

The default value is 0.0 seconds. The range is 0.0 to 440 seconds.

When you specify a value for Added Damping, the transmitter automatically rounds the value down to the nearest valid value.

Note

Added Damping values are affected by the setting of Update Rate and 100 Hz Variable.

Interaction between mA Output Damping and process variable damping

When mA Output Source is set to a flow rate variable, density, or temperature, mA Output 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 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.

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 default assignment for Channel B is Frequency Output.

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.

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.

For all scaling methods, the transmitter puts out a fixed number of pulses per unit, and at the same time, the Frequency Output signal varies in proportion to flowrate.

Calculate frequency from flow rate

The Frequency=Flow option is used to customize the Frequency Output for your application when you do not know appropriate values for Units/Pulse or Pulses/Unit.

If you specify Frequency=Flow, you must provide values for Rate Factor and Frequency Factor:

Frequency Factor

The resulting Frequency Factor must be within the range of the Frequency Output 0 to 10,000 Hz:

• If Frequency Factor is less than 1 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

• Configure → Manual Setup → Inputs/Outputs → Discrete Output → Flow Switch Setpoint

• Configure → Manual Setup → Inputs/Outputs → Discrete Output → Hysteresis

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.

Discrete Outputs have two states: ON (active) and OFF (inactive). Two different voltage levels are used to represent these states. Discrete Output Polarity controls which voltage level represents which state.

Procedure

Set Discrete Output Polarity as desired.

The default setting is Active High.

Options for Discrete Output Polarity

Polarity option Description

Active High • When asserted (condition tied to DO is

true), the circuit provides a pull-up to a site-specific voltage, maximum 30 V.

• When not asserted (condition tied to DO is

false), the circuit provides 0 V.

Active Low • When asserted (condition tied to DO is

true), the circuit provides 0 V.

• When not asserted (condition tied to DO is

false), the circuit provides a pull-up to a site-specific voltage, to a maximum of 30 V.
