2 Quick start

2.1

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

Procedure

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.

Power up the transmitter

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.

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.

2.2 Check meter status

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

Procedure

1. Wait approximately 10 seconds for the power-up sequence to complete. Immediately after power-up, the transmitter runs through diagnostic routines and checks for error

conditions. During the power-up sequence, Alert A009 is active. This alert should clear automatically when the power-up sequence is complete.

2. Check the status LED on the transmitter.

2.3

Determine the FOUNDATION Fieldbus unique device ID

The transmitter is shipped with a sticker that displays a unique 32-digit number that the fieldbus segment uses for identification. If the sticker is missing, use this procedure to determine your device ID.

Procedure

From ProLink III, navigate to Device Tools → Device Information → Transmitter Electronics → Fieldbus Device ID.

2.4 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

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

The special unit label displays only on the local display. The AI block uses and displays the actual engineering unit (i.e. lb/min).

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

18 Micro Motion 2700 Transmitters with FOUNDATION Fieldbus

Page 19

Configuration and Use Manual Configure process measurement

20000326 August 2022

The original mass flow rate value is divided by this value.

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:

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

Fieldbus host Measurement TB → FLOW_DAMPING → OD Index

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.

• Default: 0.8 seconds

• Range: 0 seconds to 51.2 seconds

• Valid damping values: 0.0, 0.1, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8, 25.6, 51.2

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.

Configuration and Use Manual 19

Page 20

Configure process measurement Configuration and Use Manual

August 2022 20000326

• 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.

• 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. 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.

Display Not available

ProLink III Device Tools → Configuration → Process Measurement → Flow

Fieldbus host Measurement TB → MASS_LOW_CUT (OD Index 38)

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.

Configure Mass Flow Cutoff

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.

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

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.

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

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.

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.

Configuration and Use Manual 31

Page 32

Configure process measurement Configuration and Use Manual

August 2022 20000326

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.

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:

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.

• 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.

• 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.

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.

The petroleum measurement application corrects line density to reference temperature according to American Petroleum Institute (API) standards. The resulting process variable is referred density.

4.7.1

The petroleum measurement parameters specify the API table, measurement units, and reference values to be used in referred density calculations.

Prerequisites

You will need API documentation for the API table that you select.

Depending on your API table, you may need to know the thermal expansion coefficient (TEC) for your process fluid.

You must know the reference temperature that you want to use.

Procedure

Configure petroleum measurement using ProLink III

1. Choose Device Tools → Configuration → Process Measurement → Petroleum Measurement.

2. Specify the API table to use to calculate referred density.

Each API table is associated with a specific set of equations.

a) Set Process Fluid to the API table group that your process fluid belongs to.

API table group Process fluids

A tables Generalized crude and JP4

B tables Generalized products: Gasoline, jet fuel, aviation fuel, kerosene, heating oils,

fuel oils, diesel, gas oil

C tables Liquids with a constant base density or known thermal expansion coefficient

(TEC). You will be required to enter the TEC for your process fluid.

D tables Lubricating oils

b) Set Referred Density Measurement Unit to the measurement units that you want to use for

referred density.

Click Apply.

These parameters uniquely identify the API table to be used to calculate referred density. The selected API table is displayed, and the meter automatically changes the density unit, temperature unit, pressure unit, and reference pressure to match the API table.

Your choice also determines the API table that will be used to calculate the correction factor for volume (CTL).

Restriction

Not all combinations are supported by the petroleum measurement application. See the list of API tables in this manual.

3. Refer to the API documentation and confirm your table selection.

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

Procedure

Configure concentration measurement using ProLink III

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

the density unit used by your matrix.

2. Choose Device Tools → Configuration → Process Measurement → Temperature and set

Temperature Unit to the temperature unit used by your matrix.

3. Choose Device Tools → Configuration → Process Measurement → Concentration Measurement.

4. Set Derived Variable to the derived variable that your matrix is designed for, and click Apply.

Important

• All concentration matrices on your transmitter must use the same derived variable. If you are using

one of the standard matrices from Micro Motion, set Derived Variable to Mass Concentration (Density). If you are using a custom matrix, see the reference information for your matrix.

Configuration and Use Manual 39

Page 40

Configure process measurement Configuration and Use Manual

August 2022 20000326

• If you change the setting of Derived Variable, all existing concentration matrices will be deleted

from transmitter memory. Set Derived Variable before loading concentration matrices.

5. Load one or more matrices. Set Matrix Being Configured to the location to which the matrix will be loaded.

b) Click Load Matrix from a File, navigate to the matrix file on your computer, and load it.

c) Repeat until all required matrices are loaded.

6. Configure or review matrix data.

a) If necessary, set Matrix Being Configured to the matrix you want to configure or review, and

click Change Matrix.

b) Set Concentration Unit to the label that will be used for the concentration unit.

c) If you set Concentration Unit to Special, enter the custom label.

d) If desired, change the matrix name.

e) Review the data points for this 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.

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).

Concentration process variables are now available on the transmitter. You can view and report them in the same way that you view and report other process variables.

Restriction

This section does not cover building a concentration matrix. See Micro Motion Enhanced Density Application Manual for detailed information on building a matrix.

4.9.1 Set reference temperature values for specific gravity using a basic FF host

When Derived Variable is set to any option based on specific gravity, you must set the reference temperature for water, then verify the density of water at the configured reference temperature. These values affect specific gravity measurement.

To check the setting of Derived Variable, read the value of the Derived Variable parameter in the Concentration Measuremnt TB.

4.9.3

Modify extrapolation alerts for concentration measurement

using a basic FF host

You can enable and disable extrapolation alerts, and set extrapolation alert limits. These parameters control the behavior of the concentration measurement application but do not affect measurement directly.

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

Each concentration matrix has its own extrapolation alert limits.

Procedure

1. Choose the matrix you want to configure using the Active Matrix parameter in the Concentration

Measuremnt TB. Each saved matrix has a unique value of 0 through 5.

2. Write the desired values into the appropriate parameters in the Concentration Measuremnt TB.

4.9.4

You must select the concentration matrix to be used for measurement. Although the transmitter can store up to six concentration matrices, only one matrix can be used for measurement at any one time.

Procedure

Choose the matrix you want to use by writing to the Active Matrix parameter in the Concentration Measuremnt TB. Each saved matrix has a unique value of 0 through 5.

Select the active concentration matrix using a basic FF host

4.10 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.

8.1

Micro Motion provides several measurement support procedures to help you evaluate and maintain your flowmeter's accuracy.

The following methods are available:

• Smart Meter Verification (SMV) evaluates the structural integrity of the sensor tubes by comparing current

• Meter validation compares flowmeter measurements reported by the transmitter to an external

• Calibration establishes the relationship between a process variable and the signal produced at the sensor.

Tip

• Perform SMV at regular intervals to get the best data on your meter's performance.

• To prove the meter against a regulatory standard, or to correct measurement error, use meter validation

• Before performing a field calibration, contact customer support to see if there is an alternative. In many

Because a change in structural integrity changes the sensor’s response to mass and density, this value can be used as an indicator of measurement performance.

You can calibrate the flowmeter for zero, density, and temperature. Density and temperature calibration require two data points (low and high) and an external measurement for each.

cases, field calibrations have a negative effect on measurement accuracy.

8.2 Use Smart Meter Verification

Smart Meter Verification™ provides in-process flow meter health verification by analyzing the meter components related to measurement performance. You can run Smart Meter Verification without stopping the process. Use this section to run a Smart Meter Verification test, view and interpret the results, set up automatic execution, and check if a field reference point has been established.

8.2.1

To use SMV, the transmitter must be paired with an 800 enhanced core processor.

See Table 8-1 for the minimum version of the transmitter, an 800 enhanced core processor, and communication tool needed to support SMV. (If you are going to perform SMV using the display, only the transmitter and enhanced core processor versions apply.)

8.2.2 SMV test preparation

Prerequisites

The following information pertains to the transmitter when connected to an 800 enhanced core processor greater than or equal to v4.7 .

• To avoid or reduce corrosion, erosion, and other process effects, make sure the sensor tube material is

compatible with the process fluid in use. For more information, see the Micro Motion Corrosion Guide.

• Important

Micro Motion highly recommends:

— Running the first Smart Meter Verification test when the flow meter is installed in the pipeline

according to the installation instructions, and the process is running at its normal operating conditions

— Running all tests thereafter at similar operating conditions

• The Smart Meter Verification test runs best when process conditions are stable. If process conditions are

too unstable, the test will abort. To maximize process stability:

— Maintain a constant fluid temperature and pressure.

— Maintain a constant flow rate. If possible, stop flow through the sensor. The sensor should be full of

process fluid.

— Avoid changes to fluid composition; for example, two-phase flow or settling.

• For all applications, run Smart Meter Verification while commissioning the meter at normal operating

conditions and then run it regularly. Micro Motion also recommends using Smart Meter Verification results along with other diagnostics like drive gain and density to help determine the health of a sensor.

• In certain scenarios, Smart Meter Verification field upgrades for pre-installed meters are possible. Contact

factory support to discuss pre-installed meter upgrades.

Zeroing the meter establishes a baseline for process measurement by analyzing the sensor's output when there is no flow through the sensor tubes.

Prerequisites

Verify the zero and prepare the meter using the procedures in Verify the zero.

Procedure

Zero the meter.

If necessary, modify Zero Time. Zero Time controls the amount of time the transmitter takes to determine its zero-flow reference point. The default Zero Time is 20 seconds. For most applications, the default Zero Time is appropriate.

Postrequisites

Restore normal flow through the sensor by opening the valves. Verify that the sensor tubes are full.

Need help?

If the zero fails:

• Verify that there is no flow through the sensor, then retry.

• Remove or reduce sources of electromechanical noise, then retry.

• Set Zero Time to a lower value, then retry.

Field Communicator Configure → Manual Setup → Measurements → Flow

Configure → Manual Setup → Measurements → Density

Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. If the transmitter value for mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor. The flowmeter’s actual measurement is multiplied by the meter factor, and the resulting value is reported and used in further processing.

Prerequisites

Identify the meter factor(s) that you will calculate and set. You may set any combination of the three meter factors: mass flow, volume flow, and density. Note that all three meter factors are independent:

• The meter factor for mass flow affects only the value reported for mass flow.

• The meter factor for density affects only the value reported for density.

Important

To adjust volume flow, you must set the meter factor for volume flow. Setting a meter factor for mass flow and a meter factor for density will not produce the desired result. The volume flow calculations are based on original mass flow and density values, before the corresponding meter factors have been applied.

If you plan to calculate the meter factor for volume flow, be aware that validating volume in the field may be expensive, and the procedure may be hazardous for some process fluids. Therefore, because volume is inversely proportional to density, an alternative to direct measurement is to calculate the meter factor for volume flow from the meter factor for density. See Alternate method for calculating the meter factor for

volume flow for instructions on this method.

Obtain a reference device (external measurement device) for the appropriate process variable.

Important

For good results, the reference device must be highly accurate.

Procedure

Determine the meter factor as follows:

a) Set the meter factor to 1 to take a sample measurement.

b) Measure the same sample using the reference device.

c) Calculate the meter factor using the following formula:

erenceMeasurement

NewMeterFactor = C

2. Ensure that the calculated meter factor does not fall outside 0.98 and 1.02. If the meter factor is outside these limits, contact customer service.

Configure the meter factor in the transmitter.

Calculating the meter factor for mass flow

The flowmeter is installed and validated for the first time. The mass flow measurement from the transmitter is

250.27 lb. The mass flow measurement from the reference device is 250 lb. The mass flow meter factor is calculated as follows:

MeterFactor

assFlow = 1 ×

250

250.27

= 0.9989

The first meter factor for mass flow is 0.9989.

One year later, the flowmeter is validated again. The mass flow measurement from the transmitter is

250.07 lb. The mass flow measurement from the reference device is 250.25 lb. The new mass flow meter factor is calculated as follows:

MeterFactor

assFlow = 0.9989 ×

250.25

250.07

= 0.9996

The new meter factor for mass flow is 0.9996.

8.4.1

Alternate method for calculating the meter factor for volume

flow

The alternate method for calculating the meter factor for volume flow is used to avoid the difficulties that may be associated with the standard method.

This alternate method is based on the fact that volume is inversely proportional to density. It provides partial correction of the volume flow measurement by adjusting for the portion of the total offset that is caused by the density measurement offset. Use this method only when a volume flow reference is not available, but a density reference is available.

Procedure

1. Calculate the meter factor for density, using the standard method.

8.5 Perform a (standard) D1 and D2 density calibration

Density calibration establishes the relationship between the density of the calibration fluids and the signal produced at the sensor. Density calibration includes the calibration of the D1 (low-density) and D2 (highdensity) calibration points.

Important

Micro Motion flow meters are calibrated at the factory, and normally do not need to be calibrated in the field. Calibrate the flow meter only if you must do so to meet regulatory requirements. Contact customer support before calibrating the flow meter.

Tip

Use meter validation and meter factors, rather than calibration, to prove the meter against a regulatory standard or to correct measurement error.

Prerequisites

• During density calibration, the sensor must be completely filled with the calibration fluid, and flow

through the sensor must be at the lowest rate allowed by your application. This is usually accomplished by closing the shutoff valve downstream from the sensor, then filling the sensor with the appropriate fluid.

• D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-density) fluid. You may use

air and water.

• If LD Optimization is enabled on your meter, disable it. To do this using a field communicator, choose

Configure → Manual Setup → Measurements → Optional Setup → LD Optimization. LD Optimization is used only with large sensors in hydrocarbon applications. If you are not using a field communicator, contact Emerson before continuing.

• The calibrations must be performed without interruption, in the order shown. Make sure that you are

prepared to complete the process without interruption.

• Before performing the calibration, record your current calibration parameters. You can do this by saving

the current configuration to a file on the PC. If the calibration fails, restore the known values.

Restriction

For T-Series sensors, the D1 calibration must be performed on air and the D2 calibration must be performed on water.

8.6 Perform temperature calibration

Temperature calibration establishes the relationship between the temperature of the calibration fluids and the signal produced by the sensor.

Prerequisites

The temperature calibration is a two-part procedure: temperature offset calibration and temperature slope calibration. The two parts must be performed without interruption, in the order shown. Ensure that you are prepared to complete the process without interruption. You will need a low-temperature calibration fluid and a high-temperature calibration fluid. You will not see the effect of the calibration until both the temperature offset calibration and the temperature slope calibration are complete.

Important

Consult customer support before performing a temperature calibration. Under normal circumstances, the temperature circuit is stable and should not need an adjustment.

9.2 Check the drive gain

Excessive or erratic drive gain may indicate any of a variety of process conditions or sensor problems.

To know whether your drive gain is excessive or erratic, you must collect drive gain data during the problem condition and compare it to drive gain data from a period of normal operation.

Excessive (saturated) drive gain

Table 9-1: Possible causes and recommended actions for excessive (saturated) drive gain

Possible cause Recommended actions

Bent sensor tube Check the pickoff voltages (see Check the pickoff voltage). If either of them are close to

zero (but neither is zero), the sensor tubes may be bent. The sensor will need to be replaced.

Cracked sensor tube Replace the sensor.

Core processor or module failure

Flow rate out of range Ensure that the flow rate is within sensor limits.

Open drive or pickoff sensor coil

Over-pressurized tubes Contact customer support.

Plugged sensor tube A dull, audible hum, and unusually high sensor vibration is usually accompanied by high,

Sensor case full of process fluid

Sensor imbalance Contact customer support.

Sensor tubes not completely full

Two-phase flow Check for two-phase flow. See Check for two-phase flow (slug flow).

even saturated, drive gain. Check the pickoff voltages (see Check the pickoff voltage). If either of them are close to zero (but neither is zero), plugged tubes may be the source of your problem. Purge the tubes. In extreme cases, you may need to replace the sensor.

Replace the sensor.

Correct process conditions so that the sensor tubes are full.

Ensure that the vibrating element is free to vibrate.

Erratic drive gain

Table 9-2: Possible causes and recommended actions for erratic drive gain

Possible cause Recommended actions

Foreign material caught in sensor tubes

• Purge the sensor tubes.

• Replace the sensor.

9.2.1 Collect drive gain data

Drive gain data can be used to diagnose a variety of process and equipment conditions. Collect drive gain data from a period of normal operation, and use this data as a baseline for troubleshooting.

Procedure

Navigate to the drive gain data.

2. Observe and record drive gain data over an appropriate period of time, under a variety of process conditions.

9.3 Check for internal electrical problems

Shorts between sensor terminals or between the sensor terminals and the sensor case can cause the sensor to stop working.

Possible cause Recommended action

Moisture inside the sensor junction box Ensure that the junction box is dry and no corrosion is

present.

Liquid or moisture inside the sensor case Contact customer support.

Internally shorted feedthrough Contact customer support.

Faulty cable Replace the cable.

Improper wire termination Verify wire terminations inside the sensor junction box. See

Micro Motion 9-Wire Flowmeter Cable Preparation and Installation Manual Micro Motion 9-Wire Flow Meter Cable

Preparation and Installation Guide.

Shorts to the housing created by trapped or damaged wires

Loose wires or connectors Contact customer support.

Liquid or moisture inside the housing Contact customer support.

Contact customer support.

9.3.1 Check the sensor coils

Checking the sensor coils can identify a cause for a no sensor response alert.

Restriction

This procedure applies only to 9-wire remote-mount transmitters and remote transmitters with remote core processors.

Procedure

Disconnect power to the transmitter.

WARNING

If the transmitter is in a hazardous area, wait five minutes after disconnecting the power. Failure to do so could result in an explosion causing death or injury.

Unplug the terminal blocks from the terminal board on the core processor.

3. Using a digital multimeter (DMM), check the pickoff coils by placing the DMM leads on the unplugged terminal blocks for each terminal pair. See the following table for a list of the coils. Record the values.

There should be no open circuits, that is, no infinite resistance readings. The left pickoff and right pickoff readings should be the same or very close (±5 Ω). If there are any unusual readings, repeat the coil resistance tests at the sensor junction box to eliminate the possibility of faulty cable. The readings for each coil pair should match at both ends.

Test the terminals in the sensor junction box for shorts to case. Test results will be inconclusive with nonconductive process fluids such as hydrocarbons.

a) Leave the terminal blocks disconnected.

b) Remove the lid of the junction box.

c) Testing one terminal at a time, place a DMM lead on the terminal and the other lead on the

sensor case.

With the DMM set to its highest range, there should be infinite resistance on each lead. If there is any resistance at all, there is a short to case.

5. Test the resistance of junction box terminal pairs.

a) Test the brown terminal against all other terminals except the red one.

b) Test the red terminal against all other terminals except the brown one.

c) Test the green terminal against all other terminals except the white one.

d) Test the white terminal against all other terminals except the green one.

e) Test the blue terminal against all other terminals except the gray one.

f) Test the gray terminal against all other terminals except the blue one.

g) Test the orange terminal against all other terminals except the yellow and violet ones.

h) Test the yellow terminal against all other terminals except the orange and violet ones.

i) Test the violet terminal against all other terminals except the yellow and orange ones.

There should be infinite resistance for each pair. If there is any resistance at all, there is a short between terminals.
