This chapter provides basic information for connecting ProLink II to your transmitter. The following topics and procedures are discussed:

• Requirements (see Section 2.2)

• Configuration upload/download (see Section 2.3)

• Connecting to a Model 1500 transmitter (see Section 2.4)

The instructions in this manual assume that users are already familiar with ProLink II software. For more information on using ProLink II, or for detailed instructions on installing ProLink II, see the ProLink II software manual, which is automatically installed with ProLink II, and is also available on the Micro Motion web site (www.micromotion.com).

Using ProLink II Required ConfigurationFlowmeter StartupBefore You Begin

2.2 Requirements

To use ProLink II with a Model 1500 transmitter with the filling and dosing application, the following are required:

• ProLink II v2.3 or later, for access to the filling and dosing application

• ProLink II v2.5 or later, for access to meter verification

• The appropriate signal converter and cables: RS-485 to RS-232 or USB to RS-232

- For RS-485 to RS-232, the Black Box Converter (Code IC521A-F) signal converter is available from Micro Motion.

- For USB to RS-232, the Black Box USB Solo (USB–>Serial) (Code IC138A-R2) converter can be used.

• 25-pin to 9-pin adapter (if required by your PC)

2.3 ProLink II configuration upload/download

ProLink II provides a configuration upload/download function which allows you to save configuration sets to your PC. This allows:

• Easy backup and restore of transmitter configuration

• Easy replication of configuration sets

Micro Motion recommends that all transmitter configurations be downloaded to a PC as soon as the configuration is complete.

To access the configuration upload/download function:

1. Connect ProLink II to your transmitter as described in this chapter.

2. Open the

File menu.

• To restore or load a configuration file to a transmitter, use the option.

2.4 Connecting from a PC to a Model 1500 transmitter

ProLink II software can communicate with a Model 1500 transmitter using Modbus protocol on the RS-485 physical layer. There are two connection types:

• RS-485 configurable connection

• SP (service port) non-configurable (standard) connection

Both connection types use the RS-485 terminals (terminals 33 and 34). These terminals are available in service port mode for 10 seconds after transmitter power-up. After this interval, the terminals revert to RS-485 mode.

• To make a service port connection, you must configure ProLink II appropriately and connect during the 10-second interval after transmitter power-up. Once a service port connection is made, the terminals will remain in service port mode. You may disconnect and reconnect as often as required, as long as you continue to use service port mode.

• To make an RS-485 connection, you must configure ProLink II appropriately, wait for the 10-second interval to expire, then connect. The terminals will now remain in RS-485 mode, and you may disconnect and reconnect as often as required, as long as you continue to use RS-485 mode.

• To change from service port mode to RS-485 mode, or vice versa, you must cycle power to the transmitter and reconnect using the desired connection type.

To connect a PC to the RS-485 terminals or an RS-485 network:

1. Attach the signal converter to the serial port of your PC, using a 25-pin to 9-pin adapter if required.

2. To connect to the RS-485 terminals, connect the signal converter leads to terminals 33 and 34. See Figure 2-1.

3. To connect to an RS-485 network, connect the signal converter leads to any point in the network. See Figure 2-2.

4. For long-distance communication, or if noise from an external source interferes with the signal, install 120-ohm, 1/2-watt resistors in parallel with the output at both ends of the communication segment.

5. Ensure that the transmitter is disconnected from a host PLC.

Flowmeter Startup

3.1 Overview

This chapter describes the procedures you should perform the first time you start the flowmeter. You do not need to use these procedures every time you cycle power to the flowmeter.

The following procedures are discussed:

• Applying power to the flowmeter (see Section 3.2)

• Performing a loop test on the transmitter outputs (see Section 3.3)

• Trimming the mA output (see Section 3.4)

• Zeroing the flowmeter (see Section 3.5)

Note: All ProLink II procedures provided in this chapter assume that your computer is already connected to the transmitter and you have established communication. All ProLink II procedures also assume that you are complying with all applicable safety requirements. See Chapter 2 for more information.

Using ProLink II Required ConfigurationFlowmeter StartupBefore You Begin

3.2 Applying power

Before you apply power to the flowmeter, close and tighten all housing covers. Turn on the electrical power at the power supply. The flowmeter will automatically perform

diagnostic routines. When the flowmeter has completed its power-up sequence, the status LED will turn green if conditions are normal. If the status LED exhibits different behavior, an alarm condition is present (see Section 5.4) or configuration of the filling and dosing application is not complete.

Configuration and Use Manual 9

Flowmeter Startup

WARNING

Upon transmitter startup or abnormal power reset, any external device controlled by a discrete output may be momentarily activated.

Upon transmitter startup or abnormal power reset, discrete output states are unknown. As a result, an external device controlled by a discrete output may receive current for a brief period.

When using Channel B as a discrete output:

• You can prevent current flow upon normal startup by setting Channel B polarity to active low (see Section 4.6).

• There is no programmatic method to prevent current flow for Channel B upon abnormal power reset. You must design the system so that a brief current flow to the external device controlled by Channel B cannot cause negative consequences.

When using Channel C as a discrete output, there is no programmatic method to prevent current flow upon either transmitter startup or abnormal power reset. You must design the system so that a brief current flow to the external device controlled by Channel C cannot cause negative consequences.

3.3 Performing a loop test

A loop test is a means to:

• Verify that the mA outupt is being sent by the transmitter and received accurately by the receiving device

• Determine whether or not you need to trim the mA output

• Select and verify the discrete output voltage

• Read the discrete input

Perform a loop test on all inputs and outputs available on your transmitter. Before performing the loop tests, ensure that your transmitter terminals are configured for the input/outputs that will be used in your application (see Section 4.3).

ProLink II is used for loop testing. See Figure 3-1 for the loop test procedure. Note the following:

• The mA reading does not need to be exact. You will correct differences when you trim the mA output. See Section 3.4.

3.4 Trimming the milliamp output

Trimming the mA output creates a common measurement range between the transmitter and the device that receives the mA output. For example, a transmitter might send a 4 mA signal that the receiving device reports incorrectly as 3.8 mA. If the transmitter output is trimmed correctly, it will send a signal appropriately compensated to ensure that the receiving device actually indicates a 4 mA signal.

You must trim the mA output at both the 4 mA and 20 mA points to ensure appropriate compensation across the entire output range.

ProLink II is used to trim the mA output. See Figure 3-2 for the mA output trim procedure. Note the following:

• Any trimming performed on the output should not exceed ± 200 microamps. If more trimming is required, contact Micro Motion customer support.

3.5 Zeroing the flowmeter

Zeroing the flowmeter establishes the flowmeter’s point of reference when there is no flow. The meter was zeroed at the factory, and should not require a field zero. However, you may wish to perform a field zero to meet local requirements or to confirm the factory zero.

Finish

Note: Do not zero the flowmeter if a high severity alarm is active. Correct the problem, then zero the flowmeter. You may zero the flowmeter if a low severity alarm is active. See Section 5.4 for information on viewing transmitter status and alarms.

When you zero the flowmeter, you may need to adjust the zero time parameter. Zero time is the amount of time the transmitter takes to determine its zero-flow reference point.

•A long zero time may produce a more accurate zero reference but is more likely to result in a zero failure. This is due to the increased possibility of noisy flow, which causes incorrect calibration.

•A short zero time is less likely to result in a zero failure but may produce a less accurate zero reference.

The default zero time is 20 seconds. For most applications, the default zero time is appropriate. You can zero the flowmeter with ProLink II or with the zero button on the transmitter. If the zero procedure fails, see Section 11.6 for troubleshooting information.

Flowmeter Startup

Additionally, if you have the enhanced core processor and you are using ProLink II to zero the flowmeter, you can also restore the prior zero immediately after zeroing (e.g., an “undo” function), as long as you have not closed the Calibration window or disconnected from the transmitter. Once you have closed the Calibration window or disconnected from the transmitter, you can no longer restore the prior zero.

3.5.1 Preparing for zero

To prepare for the zero procedure:

1. Apply power to the flowmeter. Allow the flowmeter to warm up for approximately 20 minutes.

2. Run the process fluid through the sensor until the sensor temperature reaches the normal

3. Close the shutoff valve downstream from the sensor.

4. Ensure that the sensor is completely filled with fluid.

5. Ensure that the process flow has completely stopped.

Using ProLink II Required ConfigurationFlowmeter StartupBefore You Begin

CAUTION

If fluid is flowing through the sensor, the sensor zero calibration may be inaccurate, resulting in inaccurate process measurement.

To improve the sensor zero calibration and measurement accuracy, ensure that process flow through the sensor has completely stopped.

3.5.2 Zero procedure

To zero the transmitter:

• With ProLink II, see Figure 3-3.

• With the zero button, see Figure 3-4. Note the following:

- You cannot change the zero time with the zero button. If you need to change the zero time, you must use ProLink II.

- The zero button is located on the front panel of the transmitter. To press the zero button, use a fine-pointed object that will fit into the opening (0.14 in [3.5 mm]). Hold the button down until the status LED on the front panel begins to flash yellow.

Required Transmitter Configuration

4.2 Characterizing the flowmeter

Characterizing the flowmeter adjusts the transmitter to compensate for the unique traits of the sensor it is paired with. The characterization parameters, or calibration parameters, describe the sensor’s sensitivity to flow, density, and temperature.

4.2.1 When to characterize

If the transmitter, core processor, and sensor were ordered together, then the flowmeter has already been characterized. You need to characterize the flowmeter only if the core processor and sensor are being paired together for the first time.

4.2.2 Characterization parameters

The characterization parameters that must be configured depend on your flowmeter’s sensor type: “T-Series” or “Other” (also referred to as “Straight Tube” and “Curved Tube,” respectively), as listed in Table 4-1. The “Other” category includes all Micro Motion sensors except T-Series.

The characterization parameters are provided on the sensor tag. The format of the sensor tag varies depending on your sensor’s date of purchase. See Figures 4-2 and 4-3 for illustrations of newer and older sensor tags.

Density calibration factors

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.

• 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 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 in Figure 4-2, this value is shown as

12500.

• For K2, enter the second 5 digits of the density calibration factor. In the sample tag in Figure 4-2, this value is shown as

14286.

If your sensor does not show an FD value, contact Micro Motion customer service. If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density calibration

factor. In the sample tag in Figure 4-2, this value is shown as

4.44.

Configuration and Use Manual 17

Required Transmitter Configuration

Flow calibration values

Two separate values are used to describe flow calibration: a 6-character FCF value and a 4-character FT value. Both values contain decimal points. During characterization, these are entered as a single 10-character string that includes two decimal points. In ProLink II, this value is called the Flowcal parameter.

To obtain the required value:

• For older T-Series sensors, concatenate the FCF value and the FT value from the sensor tag, as shown below.

Flow FCF X.XXXX FT X.XX

• For newer T-Series sensors, the 10-character string is represented on the sensor tag as the FCF value. The value should be entered exactly as shown, including the decimal points. No concatenation is required.

• For all other sensors, the 10-character string is represented on the sensor tag as the Flow Cal value. The value should be entered exactly as shown, including the decimal points. No concatenation is required.

4.2.3 How to characterize

To characterize the flowmeter:

1. See the menu flowchart in Figure 4-4.

2. Ensure that the correct sensor type is configured.

4.3 Configuring the channels

The six input/output terminals provided on the Model 1500 are organized into three pairs. These pairs are called Channels A, B, and C. The channels should be configured before doing any other I/O configuration.

Changing the channel configuration without verifying I/O configuration can produce process error.

When the configuration of a channel is changed, the channel’s behavior will be controlled by the I/O configuration that is stored for the new channel type, which may or may not be appropriate for the process. To avoid causing process error:

CAUTION

• Configure the channels before configuring the I/O

• When changing channel configuration, be sure that all control loops affected by this channel are under manual control.

• Before returning the loop to automatic control, ensure that the channel's I/O is correctly configured for your process. See Sections 4.5, 4.6, and 4.7.

The outputs and variable assignments are controlled by the channel configuration. Table 4-2 shows how each channel may be configured and the power options for each channel.

Note: If the mA output is configured for valve control, it cannot be used to report alarm status, and the mA output will never go to fault levels.

22 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application

Required Transmitter Configuration

Changing the channel configuration without verifying I/O configuration can produce process error.

When the configuration of a channel is changed, the channel’s behavior will be controlled by the configuration that is stored for the new channel type, which may or may not be appropriate for the process. To avoid causing process error:

CAUTION

• Configure the channels before configuring the mA output (see Section 4.3

• When changing the mA output configuration, be sure that all control loops affected by this output are under manual control.

• Before returning the loop to automatic control, ensure that the mA output is correctly configured for your process.

If the mA output is used to report mass flow or volume flow, the following parameters must be configured:

• Primary variable

• Upper range value (URV) and lower range value (LRV)

• AO (analog output) cutoff

• AO added damping

• Fault action and fault value

• Last measured value timeout

To configure the mA output, see the menu flowchart in Figure 4-7. For details on mA output parameters, see Sections 4.5.1 through 4.5.5.

4.5.1 Configuring the primary variable

The primary variable is the process variable to be reported through the mA output. Table 4-7 lists the process variables that can be assigned to the mA outputs.

Tabl e 4-7 mA output process variable assignments

Process variable ProLink II label

Mass flow Mass Flow Rate Volume flow Volume Flow Rate

Note: The process variable assigned to the mA output is always the PV (primary variable).

4.5.2 Configuring the mA output range (LRV and URV)

The mA output uses a range of 4 to 20 mA to represent the assigned process variable. You must specify:

• The lower range value (LRV) – the value of the process variable that will be indicated when the mA output produces 4 mA

• The upper range value (URV) – the value of the process variable that will be indicated when the mA output produces 20 mA

Enter values in the measurement units that are configured for the assigned process variable (see Section 4.4).

Note: The URV can be set below the LRV; for example, the URV can be set to 0 and the LRV can be set to 100.

4.5.3 Configuring the AO cutoff

The AO (analog output) cutoff specifies the lowest mass flow or volume flow value that will be reported through the mA output. Any mass flow or volume flow values below the AO cutoff will be reported as zero.

Note: For most applications, the default AO cutoff is used. Contact Micro Motion customer support before changing the AO cutoff.

Multiple cutoffs

Cutoffs can also be configured for the mass flow and volume flow process variables (see Section 6.5). If mass flow or volume flow has been assigned to the mA output, a non-zero value is configured for the flow cutoff, and the AO cutoff is also configured, the cutoff occurs at the highest setting, as shown in the following example.

Example

24 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application

Configuration:

• mA output: Mass flow

• AO cutoff: 10 g/sec

• Mass flow cutoff: 15 g/sec

As a result, if the mass flow rate drops below 15 g/sec, the mA output will report zero flow.

Required Transmitter Configuration

4.5.4 Configuring the fault action, fault value, and last measured value timeout

Note: If the mA output is configured for valve control, it cannot be used to report alarm status, and the mA output will never go to fault levels.

If the transmitter encounters an internal fault condition, it can indicate the fault by sending a preprogrammed output level to the receiving device. You can specify the output level by configuring the fault action. Options are shown in Table 4-8.

By default, the transmitter immediately reports a fault when a fault is encountered. You can configure the transmitter to delay reporting a fault by changing the last measured value timeout to a non-zero value. During the fault timeout period, the transmitter continues to report its last valid measurement.

None

(1) If the mA output fault action is set to None, the digital communications fault action should also be set to None. See

Section 6.12.1.

Tracks data for the assigned process variable; no fault action

CAUTION

Setting the fault action to NONE may result in process error due to undetected fault conditions.

To avoid undetected fault conditions when the fault action is set to NONE, use some other mechanism such as digital communications to monitor device status.

4.5.5 Configuring added damping

A damping value is a period of time, in seconds, over which the process variable value will change to reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small, rapid measurement fluctuations:

• A high damping value makes the output appear to be smoother because the output must change slowly.

• A low damping value makes the output appear to be more erratic because the output changes more quickly.

The added damping parameter specifies damping that will be applied to the mA output. It affects the measurement of the process variable assigned to the mA output, but does not affect other outputs.

When you specify a new added damping value, it is automatically rounded down to the nearest valid value. Note that added damping values are affected by the Update Rate parameter (see Section 6.7).

Note: Added damping is not applied if the mA output is fixed (i.e., during loop testing) or is reporting a fault.

Configuration and Use Manual 25

Required Transmitter Configuration

Multiple damping parameters

Damping can also be configured for the mass flow and volume flow process variables (see Section 6.6). If one of these process variables has been assigned to the mA output, a non-zero value is configured for its damping, and added damping is also configured for the mA output, the effect of damping the process variable is calculated first, and the added damping calculation is applied to the result of that calculation. See the following example.

Example

Configuration:

• Flow damping: 1

• mA output: Mass flow

• Added damping: 2

As a result:

• A change in mass flow will be reflected in the primary mA output

4.6 Configuring the discrete output(s)

Note: Configure the transmitter channels for the required output types before configuring individual outputs. See Section 4.3.

Changing the channel configuration without verifying I/O configuration can produce process error.

over a time period that is greater than 3 seconds. The exact time period is calculated by the transmitter according to internal algorithms which are not configurable.

CAUTION

• Configure the channels before configuring the discrete output (see Section 4.3

• When changing the discrete output configuration, be sure that all control loops affected by this output are under manual control.

• Before returning the loop to automatic control, ensure that the discrete output is correctly configured for your process.

The discrete outputs generate two voltage levels to represent ON or OFF states. The voltage levels depend on the output’s polarity, as shown in Table 4-9

4.7 Configuring the discrete input

Note: Configure the transmitter channels for the required input/output types before configuring the discrete input. See Section 4.3.

Changing the channel configuration without verifying I/O configuration can produce process error.

CAUTION

• Configure the channels before configuring the discrete output (see Section 4.3

• When changing the discrete output configuration, be sure that all control loops

affected by this output are under manual control.

• Before returning the loop to automatic control, ensure that the discrete output is

correctly configured for your process.

The discrete input is used to initiate a transmitter action from a remote input device. If your transmitter has been configured for a discrete input, the following actions may be assigned to the discrete input:

•Begin fill

• End fill

• Pause fill

• Resume fill

• Reset fill total

• Reset mass total

• Reset volume total

• Reset all totals

Note: If the filling and dosing application is active, the Reset All Totals function includes resetting the fill total.

To configure the discrete input, see the menu flowchart in Figure 4-9.

4.8 Establishing a meter verification baseline

Note: This procedure applies only if your transmitter is connected to an enhanced core processor and you have ordered the meter verification option. In addition, ProLink II v2.5 or later is required.

Meter verification is a method of establishing that the flowmeter is performing within factory specifications. See Chapter 10 for more information about meter verification.

Micro Motion recommends performing meter verification several times over a range of process conditions after the transmitter’s required configuration procedures have been completed. This will establish a baseline for how widely the verification measurement varies under normal circumstances. The range of process conditions should include expected temperature, pressure, density, and flow rate variations.

Configuration and Use Manual 29

Required Transmitter Configuration

View the trend chart for these initial tests. By default, the specification uncertainty limit is set at ±4.0%, which will avoid false Fail/Caution results over the entire range of specified process conditions. If you observe a structural integrity variation greater than 4% due to normal process conditions, you may adjust the specification uncertainty limit to match your process variation. To avoid false Fail/Caution results, it is advisable to set the specification uncertainty limit to approximately twice the variation due to the effect of normal process conditions.

In order to perform this baseline analysis, you will need the enhanced meter verification capabilities of ProLink II v2.5 or later. Refer to the manual entitled ProLink

Configuration and Use Manual 35

Optional Transmitter Configuration

6.4.1 About special measurement units

Special measurement units consist of:

• Base unit – A combination of:

- Base mass or base volume unit – A measurement unit that the transmitter already recognizes (e.g., kg, m

)

- Base time unit – A unit of time that the transmitter already recognizes (e.g., seconds, days)

• Conversion factor – The number by which the base unit will be divided to convert to the special unit

• Special unit – A non-standard volume flow or mass flow unit of measure that you want to be reported by the transmitter

The terms above are related by the following formula:

x BaseUnit(s)[]y SpecialUnit(s)[]=

ConversionFactor

x BaseUnit(s)[]

---------------------------------------------= y SpecialUnit(s)[]

To create a special unit, you must:

1. Identify the simplest base volume or mass and base time units for your special mass flow or volume flow unit. For example, to create the special volume flow unit pints per minute, the simplest base units are gallons per minute:

• Base volume unit: gallon

• Base time unit: minute

2. Calculate the conversion factor using the formula below:

1 (gallon per minute)

------------------------------------------------------- 0.125 (conversion factor)=

8 (pints per minute)

Note: 1 gallon per minute = 8 pints per minute

3. Name the new special mass flow or volume flow measurement unit and its corresponding totalizer measurement unit:

• Special volume flow measurement unit name: Pint/min

• Volume totalizer measurement unit name: Pints Names can be up to 8 characters long.

4. To apply the special measurement unit to mass flow or volume flow measurement, select

Special from the list of measurement units (see Section 4.4.1 or 4.4.2).

3. Specify the volume flow conversion factor.

4. Assign a name to the new special volume flow measurement unit.

5. Assign a name to the volume totalizer measurement unit.

6.4.4 Special unit for gas

For many gas applications, standard or normal volume flow rate is used as the quasi mass flow rate. Standard or normal volume flow rate is calculated as the mass flow rate divided by the density of the gas at a reference condition.

To configure a mass flow special unit that represents standard or normal volume flow rate, you must calculate the mass flow conversion factor from the density of the gas at a reference temperature, pressure, and composition.

ProLink II offers a Gas Unit Configurator tool to calculate this mass flow conversion factor. The tool will automatically update the mass flow conversion factor in the not available, special mass units can be used to set up standard or normal volume flow units for gas applications.

Note: Micro Motion recommends that you do not use the flowmeter to measure actual volume flow of a gas (volumetric flow at line conditions). If you need to measure actual volume flow, contact Micro Motion customer support.

CAUTION

The flowmeter should not be used for measuring the actual volume of gases.

Standard or normal volume is the traditional unit for gas flow. Coriolis flowmeters measure mass. Mass divided by standard or normal density yields standard or normal volume units.

6.5 Configuring cutoffs

Cutoffs are user-defined values below which the transmitter reports a value of zero for the specified process variable. Cutoffs can be set for mass flow, volume flow, or density.

See Table 6-1 for cutoff default values and related information. See Sections 6.5.1 and 6.5.2 for information on how the cutoffs interact with other transmitter measurements.

Upper limit: the sensor’s flow calibration factor, in units of L/s, multiplied by 0.2

Range: 0.0–0.5 g/cm

6.5.1 Cutoffs and volume flow

The mass flow cutoff is not applied to the volume flow calculation. Even if the mass flow drops below the cutoff, and therefore the mass flow indicators go to zero, the volume flow rate will be calculated from the actual mass flow process variable.

However, the density cutoff is applied to the volume flow calculation. Accordingly, if the density drops below its configured cutoff value, both the reported density and the reported volume flow rate will go to zero.

6.5.2 Interaction with the AO cutoff

The mA output also has a cutoff – the AO cutoff. If the mA output is configured for mass or volume flow:

• And the AO cutoff is set to a greater value than the mass and volume cutoffs, the flow indicators will go to zero when the AO cutoff is reached.

• And the AO cutoff is set to a lower value than the mass or volume cutoff, the flow indicator will go to zero when the mass or volume cutoff is reached.

See Section 4.5.3 for more information on the AO cutoff.

6.6 Configuring the damping values

• A high damping value makes the output appear to be smoother because the output must change slowly.

• A low damping value makes the output appear to be more erratic because the output changes more quickly.

When you specify a new damping value, it is automatically rounded down to the nearest valid damping value. Flow, density, and temperature have different valid damping values. Valid damping values are listed in Table 6-2.

For the Model 1500 transmitter with the filling and dosing application, the default damping value for flow has been set to 0.04 seconds. For most filling and dosing applications, the default flow damping value is used. Contact Micro Motion customer support before changing the flow damping value.

Before setting the damping values, review Sections 6.6.1 through 6.6.3 for information on how the damping values interact with other transmitter measurements and parameters.

6.6.1 Damping and volume measurement

When configuring damping values, be aware that volume measurement is derived from mass and density measurements; therefore, any damping applied to mass flow and density will affect volume measurements. Be sure to set damping values accordingly.

6.6.2 Interaction with the added damping parameter

The mA output has a damping parameter – added damping. If damping is configured for flow, the mA output is configured for mass flow or volume flow, and added damping is also configured for the mA output, the effect of damping the process variable is calculated first, and the added damping calculation is applied to the result of that calculation.

See Section 4.5.5 for more information on the added damping parameter.

Configuration and Use Manual 39

Optional Transmitter Configuration

6.6.3 Interaction with the update rate

Flow and density damping values depend on the configured Update Rate (see Section 6.7). If you change the update rate, the damping values are automatically adjusted. Damping rates for Special are 20% of Normal damping rates. See Table 6-2.

Note: The specific process variable selected for the Special update rate is not relevant; all damping values are adjusted as described.

6.7 Configuring the update rate

The update rate is the rate at which the sensor reports process variables to the transmitter. This affects transmitter response time to changes in the process.

There are two settings for Update Rate:

• When

Normal is configured, most process variables are polled at the rate of 20 times per

second (20 Hz).

• When

Special is configured, a single, user-specified process variable is reported at a faster

rate, and all others are reported at a slower rate. If you set the update rate to also specify which process variable will be updated at 100 Hz. Polling for some process variables and diagnostic/calibration data is dropped (see Section 6.7.1), and the remaining process variables are polled a minimum of 6 times per second (6.25 Hz).

Not all process variables can be used as the 100 Hz variable. Only the following process variables can be selected:

• Mass flow rate

6.8 Configuring the flow direction parameter

Note: If the mA output is configured for valve control, this parameter has no effect.

The flow direction parameter controls how the transmitter reports flow rate and how flow is added to or subtracted from the totalizers, under conditions of forward flow, reverse flow, or zero flow.

• Forward (positive) flow moves in the direction of the arrow on the sensor.

• Reverse (negative) flow moves in the direction opposite of the arrow on the sensor.

6.9 Configuring events

An event occurs if the real-time value of a user-specified process variable varies beyond a user-specified value. Events are used to perform specific actions on the transmitter. For example, the event can be defined to activate a discrete output if the flow rate is above a specified value. The discrete output, then, may be configured to close a valve.

Note: Events cannot be used to manage the filling process.

You can define one or two events. You may define the events on a single process variable or on two different process variables. Each event is associated with either a high or a low alarm.

Configuring an event includes the following steps:

1. Selecting Event 1 or Event 2.

2. Assigning a process variable to the event.

3. Specifying the Event Type:

• Active High – alarm is triggered if process variable goes above setpoint

• Active Low – alarm is triggered if process variable goes below setpoint

Configuration and Use Manual 45

Optional Transmitter Configuration

4. Specifying the setpoint – the value at which the event will occur or switch state (ON to OFF, or vice versa).

Note: Events do not occur if the process variable equals the setpoint. The process variable must be greater than (Active High) or less than (Active Low) the setpoint for the event to occur.

Example

Define Event 1 to indicate that the mass flow rate in forward or backward direction is less than 2 lb/min.

1. Specify lb/min as the mass flow unit.

2. Set Flow Direction to Absolute Value.

3. Select Event 1.

4. Configure:

• Variable = Mass Flow Rate

• Type = Active Low

• Setpoint = 2

Output Levels window.

6.10 Configuring slug flow limits and duration

Slugs – gas in a liquid process or liquid in a gas process – occasionally appear in some applications. The presence of slugs can significantly affect the process density reading. The slug flow parameters can help the transmitter suppress extreme changes in process variables, and can also be used to identify process conditions that require correction.

Slug flow parameters are as follows:

• Low slug flow limit – the point below which a condition of slug flow will exist. Typically, this is the lowest density point in your process’s normal density range. Default value is 0.0 g/cm range is 0.0–10.0 g/cm

• High slug flow limit – the point above which a condition of slug flow will exist. Typically, this is the highest density point in your process’s normal density range. Default value is 5.0 g/cm range is 0.0–10.0 g/cm

Informational panel of the Status window

;

• Slug flow duration – the number of seconds the transmitter waits for a slug flow condition (outside the slug flow limits) to return to normal (inside the slug flow limits). If the transmitter detects slug flow, it will post a slug flow alarm and hold its last “pre-slug flow” flow rate until the end of the slug flow duration. If slugs are still present after the slug flow duration has expired, the transmitter will report a flow rate of zero. Default value for slug flow duration is

0.0 seconds; range is 0.0–60.0 seconds.

46 Micro Motion® Model 1500 Transmitters with the Filling and Dosing Application

Optional Transmitter Configuration

If the transmitter detects slug flow:

• A slug flow alarm is posted immediately.

• During the slug duration period, the transmitter holds the mass flow rate at the last measured pre-slug value, independent of the mass flow rate measured by the sensor. All outputs that report mass flow rate and all internal calculations that include mass flow rate will use this value.

• If slugs are still present after the slug duration period expires, the transmitter forces the mass flow rate to 0, independent of the mass flow rate measured by the sensor. All outputs that report mass flow rate and all internal calculations that include mass flow rate will use 0.

• When process density returns to a value within the slug flow limits, the slug flow alarm is cleared and the mass flow rate reverts to the actual measured value.

Note: Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility that the transmitter will report slug flow.

Note: The slug flow limits must be entered in g/cm density. Slug flow duration is entered in seconds.

Note: If slug flow duration is set to 0, the mass flow rate will be forced to 0 as soon as slug flow is detected.

6.11 Configuring fault handling

There are four ways that the transmitter can report faults:

• By setting the mA output to its configured fault level (see Section 4.5.4 )

• By configuring a discrete output to indicate fault status (see Section 4.6)

• By setting the digital communications fault indicator (see Section 6.12.1)

• By posting an alarm to the active alarm log

Status alarm severity controls which of these methods is used. For some faults only, fault timeout controls when the fault is reported.

6.11.1 Changing status alarm severity

Status alarms are classified into three levels of severity. Severity level controls transmitter behavior when the alarm condition occurs. See Table 6-4.

6.11.2 Changing the fault timeout

By default, the transmitter immediately reports a fault when a fault is encountered. For specific faults, you can configure the transmitter to delay reporting the fault by changing the fault timeout to a non-zero value. If fault timeout is configured:

• During the fault timeout period, the transmitter continues to report its last valid measurement.

• The fault timeout applies only to the mA output and discrete output. Fault indication via digital communications is unaffected.

The fault timeout is not applicable to all faults. See Table 6-5 for information about which faults are affected by fault timeout.

6.12.2 Changing the Modbus address

The transmitter’s Modbus address is used by devices on a network to identify and communicate with the transmitter using Modbus protocol. The Modbus address must be unique on the network. If the transmitter will not be accessed using Modbus protocol, the Modbus address is not required.

Modbus addresses must be in the range 1–110, inclusive. If you are connected to the transmitter using an RS-485 connection, and you change the Modbus

address, then:

• If you are using ProLink II, ProLink II will automatically switch to the new address and retain the connection.

• If you are using a different host program, the connection will be broken. You must reconnect using the new Modbus address.

Note: Changing the Modbus address does not affect service port connections. Service port connections always use a default address of 111.

6.12.3 Changing the RS-485 parameters

RS-485 parameters control how the transmitter will communicate over its RS-485 terminals. The following parameters can be set:

•Protocol

•Baud rate

• Parity

• Stop bits

To enable RS-485 communications with the transmitter from a remote device:

1. Set the transmitter’s digital communications parameters appropriately for your network.

2. Configure the remote device to use the specified parameters.

If you are connected to the transmitter using an RS-485 connection:

• And you change the the baud rate:

- If you are using ProLink II, ProLink II will automatically switch to the new baud rate and

retain the connection.

- If you are using a different host program, the connection will be broken. You must

reconnect using the new baud rate.

• And you change the protocol, parity or stop bits, all host programs will lose the connection. You must reconnect using the new settings.

Note: Changing the RS-485 communication settings does not affect service port connections. Service port connections always use default settings.

6.12.5 Changing the additional communications response delay

Some hosts or PLCs operate at slower speeds than the transmitter. In order to synchronize communication with these devices, you can configure an additional time delay to be added to each response the transmitter sends to the remote host.

The basic unit of delay is in terms of 2/3 of one character time as calculated for the current serial port baud rate setting and character transmission parameters. This basic delay unit is multiplied by the configured value to arrive at the total additional time delay. You can specify a value in the range 1 to

255.

This chapter explains how to configure the filling and dosing application on the Model 1500 transmitter. For information on using the filling and dosing application, see Chapter 8.

CAUTION

Changing configuration can affect transmitter operation, including filling.

Changes made to filling configuration while a fill is running do not take effect until the fill is ended. Changes made to other configuration parameters may affect filling. To ensure correct filling, do not make any configuration changes while a fill is in progress.

7.2 User interface requirements

ProLink II v2.3 or later is required to configure the filling and dosing application. Alternatively, configuration can be performed via a customer-written program using the Modbus

interface to the Model 1500 transmitter and the filling and dosing application. Micro Motion has published the Modbus interface in the following manuals:

• Using Modbus Protocol with Micro Motion Transmitters, November 2004, P/N 3600219, Rev. C (manual plus map)

• Modbus Mapping Assignments for Micro Motion Transmitters, October 2004, P/N 20001741, Rev. B (map only)

Both of these manuals are available on the Micro Motion web site.

7.3 About the filling and dosing application

The filling and dosing application is used to begin flow, then end flow automatically when the target amount of process fluid has flowed through the sensor. During a fill, flow may be paused and resumed. A fill may also be ended before the target is reached.

Configuration and Use Manual 53

Configuring the Filling and Dosing Application

Transmitter outputs change state according to fill status or operator commands. The control system opens or closes valves in response to the signals from the transmitter. The filling and dosing application must be configured for the type of valve used for fill control:

• One-stage discrete – Fill controlled by a single discrete (ON/OFF) valve. The valve opens completely when the fill begins, and closes completely when the fill target is reached (or the fill is paused or ended).

• Two-stage discrete – Fill controlled by two discrete valves: a primary valve and a secondary valve. One valve must open at the beginning of the fill; the other opens at a user-defined point. One valve must stay open until the end of the fill; the other closes at a user-defined point. See Figure 7-1 for illustrations of the different opening and closing options.

• Three-position analog – Fill controlled by one analog valve which can be fully open, fully closed, or partially closed. See Figure 7-2 for an illustration of the three-position analog fill.

The Model 1500 filling transmitter provides three outputs which can be used for valve control:

• Channel B always functions as a discrete output, and can be used to control the primary valve.

• Channel C can function as a discrete output or a discrete input. When used as a discrete output, it can be assigned to control the secondary valve.

• The mA output on Channel A can function as:

- A discrete output, to control either the primary or secondary valve. When used as a

discrete output, an interposing solid-state relay is required.

- A three-level output, to control a three-position analog valve. When used as a three-level

output, the 20 mA output level sets the valve to open full, and two user-specified output levels are used to set the valve to closed and to closed partial.

Note: If Channel A is configured for valve control, the channel cannot be used to report alarm status and the mA output will never go to fault levels.

Accordingly:

• A one-stage discrete fill requires either Channel A or Channel B configured to control the primary valve.

• A two-stage discrete fill requires any valid pair of Channels A, B, and C configured to control the primary and secondary valves.

• A three-position analog fill requires Channel A configured as a three-level output.

Note: See Table 7-1 for detailed information on output options.

7.3.1 Purge

Note: Two-stage discrete filling is not supported if a purge cycle is configured. If this functionality is required, configure the mA output as a three-level output, to control the fill, and configure Channel C as a discrete output, to control the purge.

If purge will be performed, one of the following valve control configurations is required:

• Two discrete outputs (one may be the mA output configured as a discrete output). One must be assigned to the primary valve and the other must be assigned to the secondary valve. The primary valve is used to control the fill, and the secondary valve controls the purge.

• The mA output configured as a three-level output, and Channel C configured as a discrete output assigned to the secondary valve.

The second discrete output is typically set up to control compressed air or a vacuum. These techniques are used to clear any process fluid that may be left in the piping from the previous fill.

There are two purge modes: manual and automatic.

• If

Manual is configured, the Begin Purge and End Purge buttons on the Run Filler window

Purge Time. The purge may be stopped manually using the End

In both cases, the discrete output assigned to the secondary valve transmits an Open signal when the purge begins, and transmits a Closed signal when the purge ends. The primary valve remains closed throughout the purge.

The purge can be stopped at any point, by using the

7.3.2 Cleaning

Cleaning does not require any special valve configuration. When cleaning is started, all valves assigned to the system (except any valves configured for purging, as discussed in the previous section) are opened; when cleaning is stopped, all valves assigned to the system are closed.

Typically, cleaning involves flowing water or air through the system.

7.5 Overshoot compensation

Overshoot compensation keeps the actual quantity delivered as close as possible to the fill target by compensating for the time required to close the valve. Without overshoot compensation, there will always be some amount of overfill because of the time required for the transmitter to observe that the target has been reached and send the command to close the valve, and then for the control system and valve to respond. When overshoot compensation is configured, the transmitter issues the valve close command before the target is reached. See Figure 7-6.

Three types of overshoot compensation can be configured:

• Fixed – The valve will close at the point defined by the target minus the quantity specified in

Fixed Overshoot Comp.

• Underfill – The valve will close at the point defined by the AOC coefficient calculated during AOC calibration, adjusted to ensure that the actual quantity delivered never exceeds the target. (The initial adjusted target is less than the actual target, and moves upward toward the target during calibration.)

• Overfill – The valve will close at the point defined by the AOC coefficient calculated during AOC calibration, adjusted to ensure that the actual quantity delivered is never less than the target. (The variance of the fills is added to the AOC-adjusted target.)

Optional Configuration Using the FillerFiller ConfigurationUsing the Transmitter

AOC calibration is required only if Underfill or Overfill is configured. There are two forms of AOC calibration:

• Standard – Several fills are run during a special “calibration period.” The AOC coefficient is calculated from data collected from these fills. See Section 7.5.2 for instructions on the standard AOC calibration procedure.

• Rolling – The AOC coefficient is calculated from data collected from the x most recent fills, where x is the value specified for For example, if

AOC Window Length is set to 10, the first AOC coefficient is calculated from

7.5.2 Standard AOC calibration

Note: In common use, the first training fill will always be slightly overfilled because the default compensation factor is 0. To prevent this, set the AOC Coeff value in the Run Filler window (see Figure 8-1) to a small positive number. This value must be small enough so that when it is multiplied by the flow rate, the resulting value is less than the fill target.

• If flow rate has changed significantly

• If fills are consistently missing the target value

7.5.3 Rolling AOC calibration

Note: In common use, the first fill may be slightly overfilled because the default compensation factor is 0.2. To prevent this, increase the AOC Coeff value in the Run Filler window (see Figure 8-1).

Pressure Compensation

9.1 Overview

This chapter defines pressure compensation and describes how to configure it.

Note: All procedures provided in this chapter assume that your computer is already connected to the transmitter and you have established communication. All procedures also assume that you are complying with all applicable safety requirements. See Chapter 2 for more information.

9.2 Pressure compensation

The Model 1500 transmitter can compensate for the effect of pressure on the sensor flow tubes. Pressure effect is defined as the change in sensor flow and density sensitivity due to process pressure change away from calibration pressure.

Measurement Performance DefaultsTroubleshootingCompensation

Note: Pressure compensation is optional. Configure pressure compensation only if required by your application.

9.2.1 Options

There are two ways to configure pressure compensation:

• If the operating pressure is a known static value, you can enter the external pressure in the software.

• If the operating pressure varies significantly, you can use the transmitter’s Modbus interface to write the current pressure value to the transmitter at appropriate intervals.

Note: If you configure a static pressure value, ensure that it is accurate. If you update the pressure via Modbus, ensure that the external pressure measurement device is accurate and reliable.

9.2.2 Pressure correction factors

When configuring pressure compensation, you must provide the flow calibration pressure – the pressure at which the flowmeter was calibrated (which therefore defines the pressure at which there will be no effect on the calibration factor). Refer to the calibration document shipped with your sensor. If the data is unavailable, use 20 psi.

Two additional pressure correction factors may be configured: one for flow and one for density. These are defined as follows:

• Flow factor – the percent change in the flow rate per psi

• Density factor – the change in fluid density, in g/cm

/psi

Configuration and Use Manual 77

Pressure Compensation

Not all sensors or applications require pressure correction factors. For the pressure correction values to be used, obtain the pressure effect values from the product data sheet for your sensor, then reverse the signs (e.g., if the pressure effect is 0.000004, enter a pressure correction factor of –0.000004).

9.2.3 Pressure measurement unit

The default measurement unit for pressure is pressure data in psi. If you will use a different pressure measurement unit, you must configure the transmitter to use that measurement unit.

See Table 9-1 for a complete list of pressure measurement units.

10.1 Overview

This chapter describes the following procedures:

• Meter verification (see Section 10.3)

• Meter validation and adjusting meter factors (see Section 10.4)

• Density calibration (see Section 10.5)

• Temperature calibration (see Section 10.6)

Note: All procedures discussed in this chapter assume that you have established communication between ProLink II and the Model 1500 transmitter and that you are complying with all applicable safety requirements. See Chapter 2 for more information.

Note: For information on zero calibration, see Section 3.5. For information on AOC calibration, see Chapter 7.

Measurement Performance DefaultsTroubleshootingCompensation

10.2 Meter validation, meter verification, and calibration

The Model 1500 transmitter supports the following procedures for the evaluation and adjustment of measurement performance:

• Meter verification – establishing confidence in the sensor’s performance by analyzing secondary variables associated with flow and density

• Meter validation – confirming performance by comparing the sensor’s measurements to a primary standard

• Calibration – establishing the relationship between a process variable (flow, density, or temperature) and the signal produced by the sensor

To perform meter verification, your flowmeter must use the enhanced core processor and the meter verification option must have been purchased.

These three procedures are discussed and compared in Sections 10.2.1 through 10.2.4. Before performing any of these procedures, review these sections to ensure that you will be performing the appropriate procedure for your purposes.

10.2.1 Meter verification

Meter verification evaluates the structural integrity of the sensor tubes by comparing current tube stiffness to the stiffness measured at the factory. Stiffness is defined as the deflection of the tube per unit of load, or force divided by displacement. 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. Changes in tube stiffness are typically caused by erosion, corrosion, or tube damage.

Notes: To use meter verification, the transmitter must be paired with an enhanced core processor, and the meter verification option must be purchased for the transmitter.

Configuration and Use Manual 81

Measurement Performance

Meter verification either holds the last output value or causes the outputs to go to the configured fault values during the procedure (approximately 4 minutes).

Micro Motion recommends that you perform meter verification on a regular basis.

10.2.2 Meter validation and meter factors

Meter validation compares a measurement value reported by the transmitter with an external measurement standard. Meter validation requires one data point.

Note: For meter validation to be useful, the external measurement standard must be more accurate than the sensor. See the sensor’s product data sheet for its accuracy specification.

If the transmitter’s mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor. A meter factor is the value by which the transmitter multiplies the process variable value. The default meter factors are

1.0, resulting in no difference between the data retrieved from the sensor and the data

reported externally. Meter factors are typically used for proving the flowmeter against a weights and measures standard.

You may need to calculate and adjust meter factors periodically to comply with regulations.

10.2.3 Calibration

The flowmeter measures process variables based on fixed points of reference. Calibration adjusts those points of reference. Three types of calibration can be performed:

• Zero (see Section 3.5)

• Density calibration

• Temperature calibration

Density and temperature calibration require two data points (low and high) and an external measurement for each. Calibration produces a change in the offset and/or the slope of the line that represents the relationship between process density and the reported density value, or the relationship between process temperature and the reported temperature value.

Note: For density or temperature calibration to be useful, the external measurements must be accurate.

Flowmeters are calibrated at the factory, and normally do not need to be calibrated in the field. Calibrate the flowmeter only if you must do so to meet regulatory requirements. Contact Micro Motion before calibrating your flowmeter.

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

Measurement Performance

10.2.4 Comparison and recommendations

When choosing among meter verification, meter validation, and calibration, consider the following factors:

• Process interruption

- Meter verification requires approximately four minutes to perform. During these four

minutes, flow can continue (provided sufficient stability is maintained); however, outputs will not report process data.

- Meter validation for density does not interrupt the process at all. However, meter

validation for mass flow or volume flow requires process down-time for the length of the test.

- Calibration requires process down-time. In addition, density and temperature calibration

require replacing the process fluid with low-density and high density fluids, or low-temperature and high-temperature fluids.

• External measurement requirements

- Meter verification does not require external measurements.

- Zero calibration does not require external measurements.

- Density calibration, temperature calibration, and meter validation require external

measurements. For good results, the external measurement must be highly accurate.

Measurement Performance DefaultsTroubleshootingCompensation

• Measurement adjustment

- Meter verification is an indicator of sensor condition, but does not change flowmeter

internal measurement in any way.

- Meter validation does not change flowmeter internal measurement in any way. If you

decide to adjust a meter factor as a result of a meter validation procedure, only the reported measurement is changed – the base measurement is not changed. You can always reverse the change by returning the meter factor to its previous value.

- Calibration changes the transmitter’s interpretation of process data, and accordingly

changes the base measurement. If you perform a zero calibration, you can restore the factory zero at a later time. You cannot return to the previous zero (if different from the factory zero), density calibration values, or temperature calibration values unless you have manually recorded them.

Micro Motion recommends obtaining the meter verification transmitter option and performing meter verification on a regular basis.

10.3 Performing meter verification

Note: To use meter verification, the transmitter must be paired with an enhanced core processor, and the meter verification option must be purchased for the transmitter.

The meter verification procedure can be performed on any process fluid. It is not necessary to match factory conditions. Meter verification is not affected by any parameters configured for flow, density, or temperature.

During the test, process conditions must be stable. To maximize stability:

• Maintain a constant temperature and pressure.

• Avoid changes to fluid composition (e.g., two-phase flow, settling, etc.).

• Maintain a constant flow. For higher test certainty, reduce or stop flow.

Configuration and Use Manual 83

Measurement Performance

If stability varies outside test limits, the meter verification procedure will be aborted. Verify process stability and retry.

During meter verification, you must choose to fix the outputs at either the configured fault levels or the last measured value. The outputs will remain fixed for the duration of the test (approximately four minutes). Disable all control loops for the duration of the procedure, and ensure that any data reported during this period is handled appropriately.

To perform meter verification, follow the procedure illustrated in Figure 10-1. For a discussion of meter verification results, see Section 10.2.1. For additional meter verification options provided by ProLink II, see Section 10.3.2.

Measurement Performance

10.3.1 Specification uncertainty limit and test results

The result of the meter verification test will be a percent uncertainty of normalized tube stiffness. The default limit for this uncertainty is ±4.0%. This limit is stored in the transmitter, and can be changed with ProLink II when optional test parameters are entered. For most installations, it is advisable to leave the uncertainty limit at the default value.

When the test is completed, the result will be reported as Pass, Fail, or Abort:

• Pa ss – The test result is within the specification uncertainty limit. If transmitter zero and configuration match factory values, the sensor will meet factory specifications for flow and density measurement. It is expected that meters will pass meter verification every time the test is run.

• Fail/Caution – The test result is not within the specification uncertainty limit. Micro Motion recommends that you immediately re-run the meter verification test. If the meter passes the second test, the first Fail/Caution result can be ignored. If the meter fails the second test, the flow tubes may be damaged. Use the knowledge of your process to consider the type of damage and determine the appropriate action. These actions might include removing the meter from service and physically inspecting the tubes. At minimum, you should perform a flow validation (see Section 10.4) and a density calibration (see Section 10.5).

• Abort – A problem occurred with the meter verification test (e.g., process instability). Check your process and retry the test.

10.3.2 Additional ProLink II tools for meter verification

In addition to the Pass, Fail, and Abort result provided by the procedure, ProLink II provides the following additional meter verification tools:

• Test metadata – ProLink II allows you to enter a large amount of metadata about each test so that past tests can be audited easily. ProLink II will prompt you for this optional data during the test.

• Visibility of configuration and zero changes – ProLink II has a pair of indicators that show whether the transmitter’s configuration or zero has changed since the last meter verification test. The indicators will be green if configuration and zero are the same, and red otherwise. You can find out more information about changes to configuration and zero by clicking the button next to each indicator.

• Plotted data points – ProLink II shows the exact stiffness uncertainty on a graph. This allows you to see not only whether the meter is operating within specification, but also where the results fall within the specified limits. (The results are shown as two data points: LPO and RPO. The trending of these two points can help identify if local or uniform changes are occurring to the flow tubes.)

• Trending – ProLink II has the ability to store a history of meter verification data points. This history is displayed on the results graph. The rightmost data points are the most recent. This history lets you see how your meter is trending over time, which can be an important way of detecting meter problems before they become severe. You can view the graph of past results at either the beginning or the end of the meter verification procedure. The graph is shown automatically at the end. Click

View Previous Test Data to view the graph at the beginning.

• Data manipulation – You can manipulate the graphed data in various ways by double-clicking the graph. When the graph configuration dialog is open, you can also export the graph in a number of formats (including “to printer”) by clicking

• Detailed report form – At the end of a meter verification test, ProLink II displays a detailed report of the test, which includes the same recommendations for pass/caution/abort results found in Section 10.3.1. You have the options of printing the report or saving it to disk as an HTML file.

More information about using ProLink II to perform meter verification can be found in the ProLink II manual (ProLink II Software for Micro Motion Transmitters, P/N 20001909, Rev D or later) and in the on-line ProLink II help system.

Note: Historical data (e.g., previous test results or whether zero has changed) are stored on the computer on which ProLink II is installed. If you perform meter verification on the same transmitter from a different computer, the historical data will not be visible.

10.4 Performing meter validation

To perform meter validation, measure a sample of the process fluid and compare the measurement with the flowmeter’s reported value.

Measurement Performance DefaultsTroubleshootingCompensation

For T-Series sensors, the optional D3 and D4 calibrations could improve the accuracy of the density measurement. If you choose to perform the D3 and D4 calibration:

• Do not perform the D1 or D2 calibration.

• Perform D3 calibration if you have one calibrated fluid.

• Perform both D3 and D4 calibrations if you have two calibrated fluids (other than air and water).

The calibrations that you choose must be performed without interruption, in the order listed here.

Note: Before performing the calibration, record your current calibration parameters. If you are using ProLink II, you can do this by saving the current configuration to a file on the PC. If the calibration fails, restore the known values.

You can calibrate for density with ProLink II.

10.5.1 Preparing for density calibration

Before beginning density calibration, review the requirements in this section.

Sensor requirements

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.

Configuration and Use Manual 87

Measurement Performance

Density calibration fluids

D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-density) fluid. You may use air and water. If you are calibrating a T-Series sensor, the D1 fluid must be air and the D2 fluid must be water.

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

For D3 density calibration, the D3 fluid must meet the following requirements:

• Minimum density of 0.6 g/cm

• Minimum difference of 0.1 g/cm3 between the density of the D3 fluid and the density of water. The density of the D3 fluid may be either greater or less than the density of water

For D4 density calibration, the D4 fluid must meet the following requirements:

• Minimum density of 0.6 g/cm

• Minimum difference of 0.1 g/cm3 between the density of the D4 fluid and the density of the D3 fluid. The density of the D4 fluid must be greater than the density of the D3 fluid

• Minimum difference of 0.1 g/cm The density of the D4 fluid may be either greater or less than the density of water

CAUTION

between the density of the D4 fluid and the density of water.
