2.4 Commissioning

Commissioning the flowmeter consists of verifying the transmitter configuration and operation. Typically this should be done before the flowmeter is installed in the application environment. In most cases, the user-supplied variables are pre-configured in the transmitter at the factory, so the meter is ready to use upon arrival at the end user installation.

Configuration may be required if:

 Any configuration variables have changed.

 A replacement transmitter is being installed.

To commission, connect power to the device and connect a Field Communicator or Foundation Fieldbus host system to the signal loop.

1. Verify the device powers up and communicates with the Field Communicator or host system.

2. Verify transmitter configuration parameters. Following are typical parameters to check:

 Ta g

 Tra nsmit ter Mode

 Process Fluid

 Reference K-factor

 Flange Type

 Mating Pipe ID

 PV Units (configured in the AI block)

2.5 General block information

Reference information on the process control function blocks can be found in the Function Block manual document number 00809-0100-4783.

2.5.1 Modes of operation

The Resource, Transducer, and all other function blocks in the device have modes of operation. These modes govern the operation of the block. Every block supports both automatic (AUTO) and out of service (OOS) modes. Other modes may also be supported.

For the procedures described in this manual, it will be helpful to understand the following modes:

AUTO

The functions performed by the block will execute. If the block has any outputs, these will continue to update. This is typically the normal operating mode.

Out of Service (OOS)

Configuration and Operation

March 2016

The functions performed by the block will not execute. If the block has any outputs, these will typically not update and the status of any values passed to downstream blocks will be “BAD”. To make changes to the configuration of the block, change the mode of the block to OOS. When the changes are complete, change the mode back to AUTO.

MAN

In this mode, variables that are passed out of the block can be manually set for testing or override purposes.

Other types of modes

Other types of modes are Cas, RCas, ROut, IMan and LO. Some of these may be supported by different function blocks in the flowmeter. For more information, see the Function Block manual, document 00809-0100-4783.

Note

When an upstream block is set to OOS, the output status of all downstream blocks will be affected. The figure below depicts the hierarchy of blocks.

Configuration and Operation

Changing modes

To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the block is operating properly.

+86-755-8660-6182

March 2016

Permitted modes

It is possible to prevent unauthorized changes to the operating mode of a block. To do this, configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is recommended to always select OOS as one of the permitted modes.

2.5.2 Block instantiation

The Rosemount 8800D Device Revision 10 supports block instantiation. Previous device revisions do not support block instantiation. When a device supports block instantiation, the number of blocks and block types can be defined to match specific application needs. The number of blocks that can be instantiated is only limited by the amount of memory within the device and the block types that are supported by the device. Instantiation does not apply to standard device blocks like the Resource, Sensor Transducer, Analog Input, and PID Blocks.

By reading the parameter “FREE_SPACE” in the Resource Block you can determine how many blocks you can instantiate. Each block that you instantiate takes up 4.5573% of the “FREE_SPACE”.

Block instantiation is done by the host control system or configuration tool, but not all hosts are required to implement this functionality. Refer to your specific host or configuration tool manual for more information.

Reference Manual

00809-0100-4772, Rev FA

2.6 Resource Block

The Resource Block contains diagnostic, hardware and electronics information. There are no linkable inputs or outputs to the Resource Block.

2.6.1 FEATURES and FEATURES_SEL

The FEATURES parameter is read only and defines which features are supported by the flowmeter. Below is a list of the FEATURES the flowmeter supports.

FEATURES_SEL is used to turn on any of the supported features that are found in the FEATURES parameter. The default setting of the flowmeter does not select any of these features. Choose one or more of the supported features if any.

UNICODE

All configurable string variables in the flow meter, except tag names, are octet strings. Either ASCII or Unicode may be used. If the configuration device is generating Unicode octet strings, you must set the Unicode option bit.

REPORTS

The flow meter supports alert reports. The Reports option bit must be set in the features bit string to use this feature. If it is not set, the host must poll for alerts. If this bit is set, the transmitter will actively report alerts.

SOFT W LOCK and HARD W LOCK

Inputs to the security and write lock functions include the hardware security switch, the hardware and software write lock bits of the FEATURE_SEL parameter, the WRITE_LOCK parameter, and the DEFINE_WRITE_LOCK parameter.

The WRITE_LOCK parameter prevents modification of parameters within the device except to clear the WRITE_LOCK parameter. During this time, the block will function normally updating inputs and outputs and executing algorithms. When the WRITE_LOCK condition is cleared, a WRITE_ALM alert is generated with a priority that corresponds to the WRITE_PRI parameter.

The FEATURE_SEL parameter enables the user to select a hardware or software write lock or no write lock capability. To enable the hardware security function, enable the HW_SEL bit in the FEATURE_SEL parameter. When this bit has been enabled the WRITE_LOCK parameter becomes read only and will reflect the state of the hardware switch. In order to enable the software write lock, the SW_SEL bit must be set in the FEATURE_SEL parameter. Once this bit is set, the WRITE_LOCK parameter may be set to “Locked” or “Not Locked.” Once the WRITE_LOCK parameter is set to “Locked” by either the software or the hardware lock, all user requested writes as determined by the DEFINE_WRITE_LOCK parameter shall be rejected.

Configuration and Operation

March 2016

The DEFINE_WRITE_LOCK parameter allows the user to configure whether the write lock functions (both software and hardware) will control writing to all blocks, or only to the resource and transducer blocks. Internally updated data such as process variables and diagnostics will not be restricted by the security switch.

Table 2 -1displays all possible configurations of the WRITE_LOCK parameter.

2.6.3 PlantWeb™ alarms

The alarms and recommended actions should be used in conjunction with Tabl e 7-2 .

The Resource Block will act as a coordinator for PlantWeb alarms. There will be three alarm parameters (FAILED_ALARM, MAINT_ALARM, and ADVISE_ALARM) which will contain information regarding some of the device errors which are detected by the transmitter software. There will be a RECOMMENDED_ACTION parameter which will be used to display the recommended action text for the highest priority alarm. FAILED_ALARM will have the highest priority followed by MAINT_ALARM and ADVISE_ALARM will be the lowest priority.

FAILED_A LARMS

A failure alarm indicates a failure within a device that will make the device or some part of the device non-operational. This implies that the device is in need of repair and must be fixed immediately. There are four parameters associated with FAILED_ALARMS specifically, they are described below.

Reference Manual

00809-0100-4772, Rev FA

FAI LED_EN ABLED

This parameter contains a list of failures in the device which makes the device non-operational that will cause an alarm to be sent. Below is a list of the failures with the highest priority first.

1. NV memory failure

2. Sensor board electronics failure

3. Output board electronics failure

4. Thermocouple failure (MTA only)

FAILED_MASK

This parameter will mask any of the failed conditions listed in FAILED_ENABLED. A bit on means that the condition is masked out from alarming and will not be reported.

FAI LED_PR I

3.3 Environmental considerations

Avoid excessive vibration, heat, and magnetic interference to ensure maximum flowmeter life and proper operation. Typical problem areas include:

 High-vibration lines with integrally mounted electronics. Ensure the meter and

surrounding piping is properly supported.

 Warm-climate installations in direct sunlight, and outdoor installations in cold climates.

 Steam lines with improper insulation or flowmeter orientation. Follow the proper

insulation and orientation procedures described in this manual.

 High intensity electromagnetic and electrostatic fields. Although the

signal-conditioning functions reduce susceptibility to extraneous noise, some environments are more harsh than others. Avoid placing the flowmeter or its wiring close to devices that produce magnetic fields. Such devices include electric welding equipment, large electric motors and transformers, and communication transmitters.

3.4 Meter body installation tasks

Reference Manual

00809-0100-4772, Rev FA

The installation tasks include detailed mechanical and electrical installation procedures. For a general guide to meter installation, refer to Figure 2-1 on page 6.

3.4.1 Handling

Handle all parts carefully to prevent damage. Whenever possible, transport the system to the installation site in the original shipping containers. Keep the shipping plugs in the conduit connections until you are ready to connect and seal them.

Note

Do not lift the flowmeter by the transmitter. Lift the meter by the meter body. Lifting supports can be tied around the meter body as shown in Figure 3-1.

3.4.2 Flow direction

Mount the meter body so the arrow, shown on the meter body, points in the direction of flow.

3.4.3 Upstream/downstream piping

Allow enough straight pipe both upstream and downstream of the meter body to ensure a non-skewed, symmetrical profile. Ideally, the vortex meter should be installed with a minimum of 35 straight pipe diameters (D) upstream and 10 straight pipe diameters (D) downstream as shown in Figure 3-2. However, it can be installed with a minimum of 10 straight pipe diameters upstream and 5 straight pipe diameters downstream as shown in

Figure 3-3.

Rated accuracy is based on the number of pipe diameters from an upstream disturbance. An additional 0.5% shift in K-factor may be introduced between 10 D and 35 D, depending on disturbance.

The flowmeter requires gaskets supplied by the user. Be sure to select gasket material that is compatible with the process fluid and pressure ratings of the specific installation.

Note

Ensure the inside diameter of the gasket is larger than the inside diameter of the flowmeter and adjacent piping. If gasket material extends into the flow stream, it will disturb the flow and cause inaccurate measurements.

3.5.3 Meter body grounding

Installation

March 2016

Typically the meter body will be earth grounded once it is installed in the pipe. However, the meter body does have a ground lug bolt that can be used for attaching a grounding strap. Attach one end of the grounding strap to the grounding bolt and the other end to a suitable earth ground.

Note

The required bolt load for sealing the gasket joint is affected by several factors, including operating pressure and gasket material, width, and condition. A number of factors also affect the actual bolt load resulting from a measured torque, including condition of bolt threads, friction between the nut head and the flange, and parallelism of the flanges. Due to these application-dependent factors, the required torque for each application may be different. Follow the guidelines outlined in ASME PCC-1 for proper bolt tightening. Make sure the flowmeter is centered between flanges of the same nominal size as the flowmeter.

Spacers

Spacers are available with the flowmeter to maintain the Rosemount 8800A flowmeter dimensions. If a spacer is used, it should be downstream of the meter body. The spacer kit comes with an alignment ring for ease of installation. Gaskets should be placed on each side of the spacer.

3.6.1 Grounding the transmitter case

The transmitter case should always be grounded in accordance with national and local electrical codes. The most effective transmitter case grounding method is direct connection to earth ground with minimal impedance. Methods for grounding the transmitter case include:

 Internal ground connection—The internal ground connection screw is inside the

FIELD TERMINALS side of the electronics housing. SeeFigure 3-16.This screw is identified by a ground symbol ( ), and is standard on all flowmeters.

 If using a transient terminal block, the ground tab must be secured beneath the

internal ground screw.

Installation

March 2016

 External ground assembly—This assembly is located on the outside of the

electronics housing and is included with the optional transient protection terminal block (Option Code T1). This allows for a grounding strap to be run directly from the transmitter housing to earth ground. See Figure 3-17. The external ground assembly can also be ordered with the transmitter (Option Code V5) and is automatically included with certain hazardous area approvals.

Note

Grounding the transmitter case using the threaded conduit connection may not provide a sufficient ground. The transient protection terminal block (Option Code T1) does not provide transient protection unless the transmitter case is properly grounded. See

“Transient protection” on page 111 for transient terminal block grounding. Use the above

guidelines to ground the transmitter case. Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive electric current if a lightning strike occurs.

3.6.2 Commissioning tag

The flowmeters are supplied with a removable commissioning tag that contains both the Device ID and a space to record the device tag. The Device ID is a unique code that identifies a particular device in the absence of a device tag. The device tag is used as an operational identification for the device and is usually defined by the Piping and Instrumentation Diagram (P & ID).

When commissioning more than one device on a fieldbus segment, it can be difficult to identify which device is at a particular location. The removable tag provided with the transmitter can aid in this process by linking the Device ID and a physical location. For each device on the segment, the installer should note the physical location in both places on the removable commissioning tag and tear off the bottom portion. The bottom portion of the tags can be used for commissioning the segment in the control system.

Transducer Block

Rosemount

For most parameters configured in the flowmeter, the transmitter must perform extensive calculations to derive internal parameters used to accurately measure flow. It is recommended that each parameter in the Transducer Block be configured and sent to the transmitter individually. If too many parameter changes are sent to the transmitter at one time, the transmitter will return an error. The parameters not accepted will have to be re-sent.

Configuration order

The Transducer Block parameters can be configured in any order, but the following is a recommended procedure and can also be used as a checklist for configuration items.

4.3 Flow units

The flow units are configured in the AI block. If Standard or Normal flow units are selected, the density ratio must be entered in the transducer block in order for the conversion to take place. If mass units are selected, the process density must be entered.

4.3.1 Standard/normal flow units

The flowmeter allows you to measure standard or normal flow units (SCFM, SCFH, NCMM, NCMH, NCMD). Configure the software in one of two ways:

1. Enter the density ratio to convert from actual flow rate to standard flow rate.

Set target mode to something other than OOS.

See 5.2.2: Modes for corrective action.

Flow is above SENSOR_RANGE.EU100.

or flow is being simulated in the transducer block.

2. Enter the process and base conditions. (The flowmeter electronics will then calculate the density ratio for you.)

See Density Ratio and Process and Base Conditions below for definitions.

Note

Be careful to calculate and enter the correct conversion factor. Standard flow is calculated with the conversion factor you enter. Any error in the factor entered will result in an error in the standard flow measurement. If pressure and temperature change over time, use actual volumetric flow units. The flowmeter does not compensate for changing temperature and pressure.

4.4 Transducer Block

The Transducer Block contains the actual flow measurement data. The data include information about sensor type, engineering units, digital filter settings, damping, and diagnostics.

4.4.1 Process Variables (PV)

PV value

PV Value is the actual measured flow rate in the line. On the bench, the value should be zero. Check the units of the value to make sure they are configured correctly. The unit configuration is contained in the AI block.

Sensor serial number

This parameter can be entered by the user to be the serial number of the unit or any other number they would like to insert.

Sensor range

The Sensor Range is the entire flow range of the vortex meter. This includes the range that is out of the accuracy specification. If the range is between the PV Range and the Sensor Range, the status of the value is UNCERTAIN. If the Sensor Range is exceeded, the status goes to BAD and OUT OF SERVICE.

Transducer Block

March 2016

PV range

The PV Range is the range of the flowmeter that can be met with stated accuracy.

4.4.2 Basic setup

Pipe I.D.

The Pipe I.D. (inside diameter) of the pipe adjacent to the flowmeter (mating pipe) can cause entrance effects that may alter flowmeter readings. You must specify the exact inside diameter of the pipe to correct for these effects. Enter the appropriate value for this variable.

Process fluid

The flowmeter can be used for liquid or gas applications, but it must be configured specifically for the application. The standard flow meter can be configured for a liquid process fluid or a gas process fluid which includes steam. The MTA model which is capable of measuring process fluid temperature can also be configured for temperature compensated saturated steam. This model is capable of dynamically calculating the density of the saturated steam process fluid and using that density in mass flow measurements. If the flowmeter is not configured for the proper process fluid, readings will be inaccurate. Select the proper Process Fluid for your application:

Process temperature

Process Temperature and Temperature Units are needed for the electronics to compensate for thermal expansion of the flowmeter as the process temperature differs from the reference temperature. Process temperature is the temperature of the liquid or gas/steam in the line during flowmeter operation.

Process density

Process Density and Density Units are required if you have designated mass units for your flow rate units. For liquid and gas/steam process fluids, the process density is used for the conversion from volumetric units to mass units. For example, if you have set flow units to kg/sec rather than gal/sec, a density is required to convert the measured volumetric flow into the desired mass flow.

For MTA models, Process Density and Density Units are important when measuring temperature compensated saturated steam. The Process Density must be set to a nominal process fluid density so that other parameters such as PV range, Sensor Limits and Recommended Minimum Low Flow Cutoff can be accurately calculated in flow units. If the actual process density changes frequently, it may be necessary to set the process density to the highest expected value. This will allow for the required Sensor Limits of the meter.

Reference Manual

00809-0100-4772, Rev FA

Note

The user-entered process density value can also be used as a reference value for optimizing the digital “signal processing” filters. When optimizing the filters, always select a density value from the list of choices nearest and below the actual process density.

Damping

Damping changes the response time of the flowmeter to smooth variations in output readings caused by rapid changes in input. The default damping is 2.0 seconds. This can be reset to any value between 0.2 and 255 seconds.

The MTA model flowmeter has the additional capability of providing the measured process temperature. A separate damping for this measurement is provided and can be configured from 0.4 to 32.0 seconds.

4.4.3 Flow units

Density ratio

Density Ratio is used to convert the actual volumetric flow to standard/normal volumetric flow rates based on the following equations:

This value must be entered if using Standard or Normal units (SCFM, SCFH, NCMM, NCMH, NCMD). These units are configured in the AI block. The density ratio can also be calculated by entering the process and base conditions as described below (The flowmeter electronics will then calculate the density ratio for you.)

Reference K-Factor

The Reference K-factor is a calibration number assigned at the factory. It is located on the meter body tag. It should only be changed if the meter body is replaced.

Installation effects

Reference Manual

00809-0100-4772, Rev FA

Installation Effects enables you to compensate the flowmeter for installation effects. See reference graphs located in Technical Data Sheet (document number 00816-0100-3250) for the percent of K-factor shift based on entrance effects of upstream disturbances. This value can be set between +1.5% to -1.5%.

Compensated K-factor

The Compensated K-factor is based on the reference K-factor as compensated for the given process temperature, wetted materials, body number and pipe I.D. Compensated K-factor is an informational variable that is calculated by the electronics of your flowmeter.

Meter body number

The Meter Body Number is a factory set configuration variable that stores the body number of your particular flowmeter and the type of construction. The meter body number is found to the right of the body number on the meter body tag, which is attached to the support tube of the meter body.

The format of this variable is a number followed by an alpha numeric character. The number designates the body number. The alpha numeric character designates the meter body type. There are three options for the alpha numeric character:

1. None – Indicates welded meter construction

2. A – Indicates welded meter construction

3. B – Indicates cast construction

4.4.5 Filtering

Flow rate value

Flow Rate Value is the actual measured flow rate in the line. On the bench, the value should be zero. Check the units of the value to make sure they are configured correctly. The unit configuration is contained in the AI block.

Shedding frequency

Shedding Frequency is a direct indication of the shedding “vortices” across the shedder bar.

Sensor signal strength

Sensor Signal Strength is a variable that indicates the flow signal strength. This value indicates if there is enough flow signal strength for the meter to work properly. For accurate flow measurement, ideally the value should be greater than 4.0. Values greater than 4.0 will allow increased filtering for noisy applications. Values less than 4.0 may indicate applications with very low densities and/or applications with excessive filtering.

Lowpass corner

The Lowpass Corner filter sets the low-pass corner frequency to minimize the effects of high frequency noise. It is factory set based on line size and service type. Adjustments may be required only if there are problems.

Reference Manual

00809-0100-4772, Rev FA

Low flow cutoff

The Low Flow Cutoff enables adjustment of the filter for noise at no flow. It is set at the factory to handle most applications, but certain applications may require adjustment either to expand measurability or to reduce noise. It also includes a dead band such that once flow goes below the cutoff value, output does not return to the normal flow range until flow goes above the dead band.

Filter trigger level

Filter Trigger Level is configured to reject noise within the flow range while allowing normal amplitude variation of the vortex signal. Signals of amplitude lower than the Filter Trigger Level setting are filtered out. The default factory setting of “4” is optimized to work best with most applications.

Filter auto adjust

The Filter Auto Adjust is a function that can be used to optimize the range of the flowmeter based on the density of the fluid. The electronics uses process density to calculate the minimum measurable flow rate, while retaining at least a 4.0 signal strength value.

Required process density

The Required Process Density is calculated from the filter settings. It is the process density that is required to obtain an adequate sensor signal.

Resource Block

The resource block supports two modes of operation as defined by the MODE_BLK parameter:

 Automatic (Auto) The block is processing its normal background memory checks.

 Out of Service (OOS) The block is not processing its tasks. When the resource

block is in OOS, all blocks within the resource (device) are forced into OOS. The BLOCK_ERR parameter shows OUT OF SERVICE. In this mode, you can make changes to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes.

5.2.3 Alarm detection

A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the resource block are defined above (see Table 5 -2).

A write alarm is generated whenever the WRITE_LOCK parameter is cleared. The priority of the write alarm is set in the following parameter:

 WRITE_PRI

Alarms are grouped into five levels of priority as shown in Table 5 - 3.

6.1 Overview

This section provides descriptions of analog input function block parameters and the engineering units that are supported by the flowmeter.

6.2 Analog Input (AI) Function Block

The Analog Input (AI) Function Block processes the measurement from the Transducer Block and makes it available to other function blocks. The output from the AI Block is in engineering units and contains a status indicating the quality of the measurement. There is one AI Block for each measurement performed by the transmitter.

6.2.1 Configure the AI Block

A minimum of four parameters are required to configure the AI Block:

 CHANNEL

 L_TYPE

 XD_SCALE

 OUT_SCALE

Refer to Ta b le 6 - 2 for analog input function block system parameters. Refer to Tab l e 6- 3 for supported engineering units.

CHANNEL

Select the channel that corresponds to the desired sensor measurement. Refer to Table 6- 1 .

Table 6-1. I/O Channel Definitions

L_TYPE

The L_TYPE parameter defines the relationship of the sensor measurement to the desired output of the AI block. The relationship can be direct, indirect, or indirect square root.

Direct

Select direct when the desired output will be the same as the sensor measurement. This is the most common configuration for the Vortex flow measurement. The Vortex meter is a linear meter.

Indirect

Select indirect when the desired output is a calculated measurement based on the sensor measurement. The relationship between the sensor measurement and the calculated measurement will be linear.

Indirect Square Root

Select indirect square root when the desired output is an inferred measurement based on the sensor measurement and the relationship between the sensor measurement and the inferred measurement is square root. Indirect square root should not be used with the Vor tex meter.

Reference Manual

00809-0100-4772, Rev FA

XD_SCALE and OUT_SCALE

The XD_SCALE and OUT_SCALE each include three parameters: 0%, 100%, and engineering units. Set these based on the L_TYPE:

L_TYPE is Direct

XD_Scale 0% = 0

XD_Scale 100% = desired upper range value

XD_Scale units = desired flow units. See Tab l e 6- 3 for supported engineering units.

Note

XD_Scale units are written to transducer block units.

L_TYPE is Indirect

When an inferred measurement is made based on the sensor measurement, set the XD_SCALE to represent the operating range that the sensor will see in the process. Determine the inferred measurement values that correspond to the XD_SCALE 0 and 100% points and set these for the OUT_SCALE.

Troubleshooting

Expected flow in pipe does not match the transmitter flow reading

Basics

 Check and verify configuration parameters in this order: K-factor, process fluid,

transmitter mode, fixed process temperature, fixed process density, density ratio, pipe diameter, trigger level, low-flow cutoff, and low-pass corner frequency.

 Check sizing. Make sure the predicted flow is within the measurable flow limits.

 See Appendix C: Electronics verification for electronics verification procedure.

Possible application problems

 If the process is air or a gas and when reading in standard or normal units, verify the

density ratio is correct. Also verify the process density is correct and the signal processing filters are optimized for the process density.

 Check signal_strength in the Transducer Block. Signal_strength should ideally be

greater than or equal to 4 to indicate a sufficient flow signal.

 If using a remote mount installation, verify that no 50Hz or 60Hz interference is

coupling in to the flow meter and being interpreted as flow. Verify the remote sensor cable is connected properly.

 If the process is a liquid, check for flashing or cavitation. This will cause the flow

reading to be erratic. Check the line temperature and pressure. If possible, increase back pressure.

 Where applicable, verify viscosity and specific gravity requirements for the line size.

All installations

 Verify any valve(s) in series with the meter are operating properly.

 Verify there are no parallel bypass lines running flow.

Troubleshooting

Pipe/line vibration

 Add support to the process piping as near the meter as possible. This will help to

dampen vibration at the meter.

 If the vibration frequency is “in band” with the flow signal, it may be possible to

adjust the signal processing filters, specifically the low flow cutoff point to ignore the vibration.

 Rotate the meter body 90 degrees.

Flow in pipe but transmitter indicates zero flow

Basics

 Check to make sure that the meter is installed with the arrow in the direction of flow.

 Check and verify configuration parameters in this order: K-factor, process fluid,

transmitter mode, fixed process temperature, fixed process density, density ratio, pipe diameter, trigger level, low-flow cutoff, and low-pass corner frequency.

 Check sizing. Make sure the predicted flow is within the measurable flow limits.

 See Appendix C: Electronics verification for electronics verification procedure.

Possible application problems

 Check signal_strength in the Transducer Block. Signal_strength should ideally be

greater than or equal to 4 to indicate a sufficient flow signal. If the number is below 4, verify the “process density” is correct and the signal processing filters are optimized for the process density. If the signal_strength is “zero” refer to the Vortex sensor and

remote sensor cable section below.

 If the filters are set correctly and the signal strength is still weak (less than 4), it is

possible the actual flow is below the low flow cutoff setting. Lower the low_flow_cutoff and/or the trigger. Monitor the signal strength again to see if it has increased.

 For liquid applications with the meter installed horizontally, verify the pipe is full.

Vortex sensor and remote sensor cable

 If using a remote mount installation, inspect the black coaxial remote sensor cable

for cracks, cuts or other physical damage. If the cable is visibly damaged it should be replaced. Note: The Vortex remote mount sensor cable is NOT field repairable.

 Disconnect the remote sensor cable at the transmitter. Using an ohmmeter on its

highest range, measure the insulation resistance of the remote sensor cable by measuring between the center conductor and the outer conductor. It should be greater than 1 MΩ. If not, disconnect the remote sensor cable at the flow sensor. Measure the cable again and see if the insulation resistance is greater than 1 MΩ. Refer to Figure 7-17 and Table 7-3 on page 107 for detailed cable troubleshooting. If less than 1 MΩ, the cable should be replaced. If it measures 1 MΩ or greater, then measure the flow sensor resistance at the sensor SMA connector. It should read greater than 1 MΩ resistance between the center conductor and the outer metal jacket. If not, the sensor is defective and should be replaced.

 If the Vortex sensor has been damaged by “water hammer” it may not be sitting on

the meter body post properly. The only way to verify this is to remove the sensor. See

7.5.4: Replacing the sensor.

Electronics

 See Appendix C: Electronics verification for electronics verification procedure.

 Check sizing; make sure the predicted flow is within the measurable flow limits.

Pipe/line vibration

In many cases if the Vortex transmitter indicates some flow when there is no actual flow, it is due to pipe or line vibration. If there is obvious vibration, follow these recommendations:

 Add support to the process piping as near the meter as possible. This will help to

dampen vibration at the meter.

 If the vibration frequency is “in band” with the flow signal, it may be possible to

adjust the signal processing filters—specifically the “low flow cutoff” point—to ignore the vibration.

 Rotate the meter body 90 degrees.

50/60 Hz Measurement

 Verify that no 50Hz or 60Hz interference is coupling in to the flow meter and being

interpreted as flow. Verify the remote sensor cable is properly earth grounded.

 If the remote sensor cable runs near other cables carrying large AC currents, separate

the cables. The Vortex sensor cable should not be placed near other cables carrying high current.

 Lastly, if feasible, integrally mount the electronics to the meter body to see if the

problem goes away.

Troubleshooting

Application Problems

 Verify any valve or valves in series with the meter are closed entirely.

 Check if any pump pulsations are disturbing flow.
