1. GENERAL INFORMATION

1.1 General

Vortex Shedding is not new. Da Vinci observed vortex shedding in 1513. Von Karman provided an empirically determined formula for it in 1911-1912. One observes it as eddies downstream of a rock or a piling in a fast moving stream. Yet, it wasn’t until it was successfully developed and installed in the late 1960’s that this significant development in the science of flow measurement was given considerable attention by industry.

1.2 Principles of Operation

With the controlled use of an obstruction installed in a given pipeline, vortices are generated downstream of the obstruction when fluid or gas flows through a pipe. A vortex is a swirling low pressure eddy which forms alternately from side to side of the bluff body. With each eddy, there is formed a corresponding high pressure pulse opposite the bluff body. (See Figure 1.) These pulses are directly proportional to the velocity of a given fluid. Each pulse represents given volumetric units of fluid for a given line size. Since each pulse represents a unit volume, the output is therefore linear with respect to flow rate.

FIGURE 1

1.3 Sensor Operation

Two pressure sensing devices are mounted in the pipe wall of the flow meter. Inserted in its center is a stainless steel bluff body, on either side of which alternating stresses are induced in response to the forming and shedding of vortices. The piezo electric sensors detect the pressure pulses, and their energy content is amplified in the preamplifier and processed to furnish an output proportional to the rate of flow.

1.4 Calibration Factor

The frequency at which vortices are shed is a linear function of fluid velocity, and therefore, a measure of flow. Vortex frequency is insensitive to density (temperature, pressure), the total volumetric flow of compressible fluids should however be adjusted to flow conditions other then calibration conditions. In the range covered by the particular flowmeter, vortex frequency is insensitive to specific gravity, viscosity, and temperature of the fluid and depends only upon the width (d) in inches and shape of the flow element, and the inside diameter (D) of the pipeline in inches.

The frequency is: F = SV/d

where : F = Karman vortex frequency

S = constant (Strouhal Number) V = fluid velocity at the flow element d = face width of the element

The frequency relationship is accurately linear and reproducible, eliminating the need for “wet calibration.” (See Figure 2.)

2. HANDLING AND STORAGE

FIGURE 2

2.1 Handling Precautions

The vortex flow meter has been tested at the factory. When the instrument is received, it should be inspected for damage due to mishandling during shipment. If damage is evident, report it to the carrier immediately and have them present when the case is opened. They are responsible for any damage during shipment. If you have any problems or questions, consult the factory or your local representative.

2.2 Storage

After receiving the Flow Meter, care should be taken to avoid unnecessary damage. If the meter is not scheduled to be installed soon after delivery, the following steps should be observed:

A) After inspection, the meter should be repacked into its original packing.

B) If the meter being stored has been previously installed, care should be

taken to remove all process fluids and corrosives.

C) Select a clean, dry site free of mechanical vibration, shock and chemical

corrosives.

3. INSTALLATION

3.1 Installation

The Aalborg7 vortex flow meter is designed to operate under a wide variety of conditions. To ensure its longevity of operation, precautions should be taken before and during its installation.

3.2 Selecting the Installation Site

A) The vortex meter requires a minimum of 20 straight diameters upstream

and 5 straight unobstructed diameters of downstream piping. One diameter is equal to the internal pipe diameter. This is necessary to ensure regulated formation of vortices. (See Figure 3 for the piping requirements chart for various piping recommendations.)

B) Choose a site with minimal mechanical vibrations.

C) Avoid areas of high humidity or corrosive atmosphere where possible.

D) When installing the meter, choose a site which is accessible and allows

ease of wiring and maintenance.

VALVES

Note : Straight pipe length on the downstream side to be 5 pipe diameters minimum. *D = Pipe internal diameter.

To ensure the high accuracy of flow measurement specified on the identification sheet, piping and installation instructions must be followed carefully.

A) The pipe immediately up and down stream of the flow meter must be of

sufficient length, straight and free of obstructions. Refer to the piping requirements chart for exact dimensions (Figure 3).

B) It is recommended that straightening vanes be used on all vortex meters,

but it is not necessary.

C) The schedule of the pipe being used must match the schedule of the

meter for at least 20 diameters upstream and 5 diameters downstream of the flow meter.

D) When the vortex meter is being used as a controller, it is recommended

that any regulating valve be located downstream of the flow meter.

E) Weld beads on the internal wall of the pipe before or after the flow meter

should be ground flush with the pipe wall before the meter is installed.

F) Proper style and proper size gaskets should always be used when

installing the flow meter.

G) The meter body and signal processor may be rotated into any position

permitted by the pipe flanges. The flow meter has no moving parts and is not position sensitive.

3.4 Temperature and Pressure Taps (Optional)

Installation of temperature and pressure transducers (if used) should be in accordance with the manufacturer’s specifications.

A) The temperature transducer should be installed between 2.5 and 3.5

diameters from the downstream side of the wafer body. Consult the factory for the exact dimensions, or refer to additional information at the end of this manual.

B) The pressure transducer should be installed between 2.0 and 3.5

diameters from the upstream side of the wafer body. Consult the factory for the exact dimensions, or refer to additional information at the end of this manual (See Figure 4).



3.5 Orientation

FIGURE 4

The flow meter uses piezo-electric sensing elements with no moving parts. This eliminates wear and allows for vertical or horizontal installation.

3.6 Alignment Rings and Gaskets

Alignment rings may be provided with the meter and should be used to ensure proper alignment of the flow meter to the pipe flanges. Misalignment can result in percentage errors and can even result in a non-functional meter.

Gasket size and correct installation are essential to accurate measurement. Care should be taken when installing the flow meter to prevent the slightest protrusion of the gasket into the flow line. The I.D. of the gasket should be 1/8 inch larger than the I.D. of the meter. This will prevent the gasket from slipping into the line during installation.

3.7 Identification Check

Before continuing on to the installation of the flow meter, be sure that all of the parameters of the application match or fall within the limits specified by the identification sheet. If more than one meter has been purchased, check the I.D. sheet versus the meter tag to ensure that the correct meter is being installed.

3.8 Installation Procedure

The Vortex Wafer flow meter is a flangeless style meter. It is installed between pipe flanges using alignment rings through bolts and gaskets. The inside diameter of the surrounding pipe should be identical to the I.D. of the meter.

The following installation procedures should be used to insure proper alignment of the flow meter which in turn will insure accuracy:

A) Check the weldmount mating flanges for internal weld bead. If weld bead

exists in the pipeline, it must be ground flush with the pipe wall. Failure to do this will result in high percentage errors and erratic outputs.

B) Check the pipe for proper alignment on both sides of the installation

location.

C) Check the overall piping. Be sure it meets or exceeds minimum straight

upstream and downstream requirements, approximately 20 diameter upstream and 5 diameters downstream.

D) Check for adequate clearance on both sides of the signal processor

housing. A minimum distance of 24 inches is required for ease of wiring and maintenance.

E) For meters over 150 lb. flange ratings, place the two purchased alignment

rings over the ends of the meter body.

F) Place the flange gaskets between the meter body and the opposing

flanges of the pipeline. Be sure that the arrow on the meter body is indicating the correct direction of flow.

G) Insert the bolts through the bolt holes in the flanges and run the nuts

onto the bolts. Snug the nuts tight enough to hold the alignment.

H) Check the alignment of the meter body to the pipeline. Check the

concentricity of the gaskets, being sure that they are not protruding into the flow line. The bolts should bear against the outside of the flange bolt holes. (See Figure 5, end view of flange, alignment ring and gasket.)

4.3 Handling and Storage

The smart transmitter has been tested and programmed at the factory. When the transmitter is received, it should be inspected for damage due to mishandling during shipment. If damage is evident, report it to the carrier immediately and have them present when the carton is opened. The carrier is responsible for any damage during shipment. If you have any problems or questions, consult the factory or your local representative.

After receiving the unit, handle with care to avoid any unnecessary damage. If the unit is not scheduled to be installed immediately after delivery, the following steps should be observed:

A) After inspection, the transmitter should be repacked into its original

packing.

B) Select a clean, dry place to store the meter.

C) Avoid areas of extreme temperatures. The unit should be stored in an area

that falls between -15 °F and +149 °F.

4.4 Mounting

The transmitter enclosure for remote option has two mounting feet for easy wall mounting. The enclosure should be located within 100 feet from the pipeline sensor, and ideally should be at eye level for easy viewing and access to the keypad for programming.

High-Temperature Installations:

Install the meter body so the electronics are positioned to the side of or below the pipe. Insulation may be required around the pipe to maintain a temperature below 149 °F (65 °C).

4.5. Wiring Connections

The transmitter module fits snugly within the enclosure, but will slide out by hand without the necessity of a tool for removal.

CAUTION: Make proper grounding connections before switching on

power. Grounding the flow meter and transmitter modules is one of

the most important procedures of Vortex installation. Proper

grounding ensures correct and accurate flow measurement.

Use dedicated Grounding Clamp on the meter and transmitter body

(see pages 105-107) to make the proper connection to building

protective earth.

WARNING:

Some of the IC devices used in the transmitter are static sensitive and

may be damaged by improper handling. When adjusting or servicing

the transmitter, use of a grounded wrist strap is recommended to

prevent inadvertent damage to the integral solid state circuitry.



CAUTION: Do not apply power voltage above 30Vdc. Doing so will

cause Vortex meter damage or faulty operation.

Make sure power is OFF when connecting or disconnecting any cables

in the system.



The TB1 – TB4 terminals accept 14 to 24 gauge wires, but 18 gauge shielded wire (Belden 8760) or 20 gauge shielded wire (Belden 9154) is recommended. When making wiring connections, cable glands should be fitted and sealed to prevent moisture entering the enclosure.

4.5.1 Power Supply Connections

The power supply requirements for Vortex flow meter are: 15 to 30 Vdc 100 mV maximum peak to peak output noise, (unipolar power supply)

Terminal TB1, Pin 1 --------------- DC Power (+) Terminal TB1, Pin 2 --------------- DC Power (-) Terminal TB1, Pin 3 --------------- GND, building protective earth

(connect to dedicated GND clamp inside of the enclosure).

The (+) and (-) power inputs are each protected by a 300mA M (medium timelag) resettable fuse. If a shorting condition or polarity reversal occurs, the fuse will cut power to the flow transducer circuit. Disconnect the power to the unit, remove the faulty condition, and reconnect the power. The fuse will reset once the faulty condition has been removed.

NOTE: For remote transmitter option use shielded twisted pair cable in order to reduce EMI on sensors signals. Use 24 AWG or larger wire and do not exceed 100 feet (30 meters). Use supplied cable termination kit to properly terminate the transmitter end of the signal cable.

The termination kit includes:

1. Molex 3 position Connector Housing (P/N: 50-57-9403) 1 ea.

2. Molex Female Connector Terminals (P/N: 16-02-1114) 3 ea.

Make sure to connect terminal #4 on the meter side to pin #2 (central pin) on the Molex connector (see APPENDIX D on page 104 for more details)



This linear output signal by default represents 0-100% of the selected process variable full scale range. User may adjust 4mA and 20 mA settings individually for each output if different range of the process variable is required (see Paragraph 5.3.12.4)

DATA ENTRY AND CONFIGURATION

5.1 Display Indications

Initially, after the power is first turned on, the Banner Screen is shown for 1 second, then flow meter model number is shown in the first line of the display and the revisions for EEPROM table and firmware in the second line. Subsequently the actual process information is displayed.

Figure 5.1: Vortex meter first Banner Screen

Figure 5.2: Vortex meter second Banner Screen

Figure 5.3: Vortex meter initial PI Screen

Based on flow meter configuration (with or without Temperature/Pressure option), different parameters may be displayed in the Process Information (PI) screen by pressing the Up or Dn pushbuttons.

Process Information screens can be configured to be static or dynamic (see Paragraph 5.3.11 “Display Menu”). Using Screen Mask settings user can enable (unmask) or disable (mask) up to 13 different process variable combinations (see Figure 5.4).

5.2 Menu Sequence

The listing below gives a general overview of the standard top-level display menu sequence when running firmware version A001. The ESC pushbutton is used to toggle between the process mode (PI screens) and the Setup menus.

The listing in Section 5.2 shows the standard display menu sequence and submenus using the UP button to move through the menu items. The first message displayed the first time the ESC button is pressed after the meter is powered up is “Prog. Protection ON”. Thereafter, pressing the ESC button while the flow meter is in monitoring mode (PI screens) will display the parameter that was last exited. Program Protection may be turned “off” by pressing the ENT pushbutton when the Program Protection menu is displayed. The firmware will prompt with “Change Prog Prot”. Pressing UP or DN button will toggle current protection status. If password is set to any value more than zero, the firmware will prompt with “Enter Prot Code”. User has to enter up to 3 digits program protection code, in order to be able to access password protected menus. Once correct password is entered, program protection is turned off until unit is powered up again.

When the last menu item is reached, the firmware “wraps around” and scrolls to the first item on the menu once again (see Figure 5.5). The menu items in the first column are upper-level configuration mode functions. Submenu selections are shown on the Figure 5.6). The allowable selections of sub-menu items which are selected by tabular means are shown in detail in Section 5.3.

5.3 Parameter Entry

There are two methods of data entry: • Direct numerical number entry.

• Tabular Input from a table menu.

If menu with direct numerical entry is selected use Up button to increment digit value from 0-9. Use Dn button to move cursor to another digit position. When desired value is entered use ENT button to accept (save in the EEPROM) new value.

If menu with tabular entry is selected, the available menu options can be set with the Up and Dn buttons and are accepted by pressing ENT button.

5.3.1 Submenu Program protection

After power has been turned on, programming parameters may only be changed by turning program protection “OFF”. There are two ways to turn off the program protection:

1. If program protection code (PP-code) is set to “0” (factory default), the program protection is turned off by pressing ENTER key.

2. If a PP-code (1 to 255) other than “0” has been entered, this code must be entered in order to turn the program protection “OFF”.

The PP-code can be changed after the program protection has been turned off.

In order to protect device configuration parameters when changing the PP-code

the old PP-code must be entered after ENTER has been pressed.

NOTE: During data entry the input values are checked for acceptability. If data is not acceptable, it is rejected and a message is generated indicating that the new data has not been accepted.



NOTE: Program the Measuring Units first because later menus may be based on the units selected.

Use the Measuring Units Menu to configure the flow meter with the desired units of measurement. These are global settings and determine what appears on all process information screens and data log records. Units should be selected to meet your particular metering needs.

The instantaneous flow rate may be simultaneously displayed in Volumetric and Mass engineering units. In addition to conventional flow units user defined flow engineering units may be configured for Volumetric and Mass flow units. Before using Volumetric User defined flow unit make sure proper conversion factor of the new unit with respect to one liter is set (the default entry is 1.00 Liter). Before using Mass User defined flow unit make sure proper conversion factor of the new unit with respect to one gram is set (the default entry is 1.00 gram) Also proper time base values for both User Defined Units have to be set. The following selections are available: 1 second, 60 seconds (1 minute), 3600 seconds (1 Hour), 86400 seconds (1 Day). The default entry is 60 seconds.

The Volumetric flow rate for Gases may be shown with following units conditions: Standard, Normal, and Actual. The temperature and pressure for Standard and Normal conditions can be programmed in the Flowing Fluid menu (see Paragraph

5.3.9). By default Standard conditions are: 70 °F and 14.7 PSIA, Normal conditions are 0 °C and 101.3 KPa.

For flow meters with T/P hardware installed the actual process temperature and pressure derived from corresponding sensors. For flow meters without T/P hardware the actual process temperature and pressure should be preset in the Flowing Fluid menu (see Paragraph 5.3.9).



NOTE: Your flow meter is pre-programmed at the factory for your application’s process fluid and T/P conditions and does not require any reprogramming unless your process fluid or T/P conditions are changed.



NOTE: If Gas is selected as flowing fluid, when Standard Volumetric units are selected the prefix S will precede engineering units name on the PI screens (for example: Slitr/min). When Normal Volumetric units are selected the prefix N will precede engineering units name on the PI screens (for example: Nlitr/min). For Actual Volumetric units there will be no prefix in front of engineering unit name (for example: litr/min). Flow Units Conditions settings only applicable for Volumetric Flow units. For Liquids the Flow Units conditions are always Actual.

5.3.4 Submenu L1 Alarm Menu

5.3.4.1 Submenu L2 Flow Alarm

Vortex flow meter provides the user with a flexible alarm/warning system that monitors the Fluid Flow for conditions that fall outside configurable limits as well as visual feedback for the user via the LCD or via an optically isolated outputs. The flow alarm has several attributes which may be configured by the user via LCD/Keypad or digital communication interface. These attributes control the conditions which cause the alarm to occur and to specify actions to be taken when the flow rate is outside the specified conditions. Flow Alarm can be assigned to Volumetric or Mass Flow reading.

Flow Alarm conditions become true when the current flow reading is equal or higher/lower than corresponding values of high and low flow alarm levels. Alarm action can be assigned with preset delay interval (0-3600 seconds) to activate the optically isolated output (separate for High and Low alarm). Latch Mode control feature allows each optical output to be latched on or follow the corresponding alarm status.

Following settings are available for Flow Alarm (see Figure 5.8):

a) Flow Alarm Mode Tabular entry

This function determines whether Flow Alarm is Enabled or Disabled. The following selections are available: Enabled or Disabled. The default entry is Disabled. Alarm Mode selections can be set with the Up and Dn buttons and are accepted by pressing ENT button.

5.3.5.1 Submenu L2 Totalizer#1 and Totalizer#2 Menus

Vortex flow meter provides the user with two independent Programmable Flow Totalizers. Each Totalizer can be configured for Volumetric or Mass flow.

The total volume of the flowing fluid is calculated by integrating the actual instantaneous fluid flow rate with respect to time. The Totalizers value are stored in the Battery Backed RAM and saved every 1 second. In case of power interruption the last saved Totalizers values will be loaded on the next power on cycle, so Totalizers reading will not be lost. The LCD/keypad and digital communication interface commands are provided to:

- Enable/Disable totalizing the flow

- configure totalizer to Volumetric or Mass flow process variable

- start the totalizer at a preset flow rate (in current Vol. or Mass flow units)

- assign action at a preset total volume (Event Volume)

- reset the totalizer to ZERO

NOTE: Before enabling the Totalizer, ensure that all totalizer settings are configured properly. Totalizer Start values have to be entered in currently active Volumetric or Mass flow engineering unit. The Totalizer will not totalize until the process flow rate becomes equal to or more than the Totalizer Start value. Totalizer Event values must be entered in currently active volume or mass based engineering units. If the Totalizer Event at preset total volume feature is not required, then set Totalizer Event value to zero (default settings).

The flow Pulse Output is operating independently from totalizers and based on configuration settings (see Figure 5.9) can provide pulse frequency proportional to instantaneous fluid flow rate.

The LCD/keypad and digital communication interface commands are provided to:

- Enable/Disable Pulse Output

- configure Pulse Output for Volumetric or Mass flow process variable

- configure the Unit/Pulse value (in current Vol. or Mass flow units)

- configure Pulse Active On Time (50 - 13000 ms)

NOTE: The Pulse Output minimum Active On time is a 50 millisecond (.05 second). The Optical Pulse Output cannot operate faster than one pulse every 100 millisecond (.1 second). A good rule to follow is to set the Unit/Pulse value equal to the maximum flow in the same units per second. This will limit the pulse rate to no faster than one pulse every second.

The Totalizer has been reset!

For example: Maximum flow rate = 1200 kg/min

(1200 kg/min = 20 kg/sec) If unit per pulse is set to 1200 kg per pulse, the Optical Pulse Output will pulse once every minute. If unit per pulse is set to 20 kg per pulse, the Optical Pulse Output will pulse once every second.

The Optically isolated Pulse Output incorporate Pulse output queue, which accumulate pulses if the Pulse Output is accumulating process flow faster than the pulse output hardware can function. The queue will allow the pulses to “catch up” later if the flow rate decreases. A better practice is to slow down the Pulse Output by increasing the value in the Unit/Pulse setting in the Pulse Output menu (see Figure 5.9).

5.3.6.1 Submenu L2 Analog 4-20mA Menus

Vortex Flow Meters are equipped with two channels programmable analog 4-20 mA outputs. Each channel can be individually assigned to one of the following process variables: Volumetric Flow, Mass Flow, Temperature*, Pressure*. By default channel #1 is set to Volumetric Flow and channel #2 is set for Mass flow. For each channel 4 mA and 20 mA points, which define the flow meter output range, can be preset to maximize resolution of analog output. The meter is most accurate when operated within the expected flow ranges for your application. Setting the range to the limits of expected readings will maximize flow meter performance.

When adjusting 4-20mA limits, the value of the limits have to be entered in currently selected (global) for particular process variable engineering units.

5.3.6.2 Submenu L2 Digital Optical Outputs Menus

Two sets of optically isolated digital outputs are provided to actuate user supplied equipment. These are programmable via digital interface or LCD/Keypad such that the outputs can be made to switch when a specified event occurs (e.g. when a low or high flow alarm limit is exceeded or when the totalizer reaches a specified value) or may be directly controlled by user.

The user can configure each optical output action from 14 different options:

- Disabled: No Action (output is not assigned to any events and not energized)

- Low Flow Alarm

- High Flow Alarm

- Range between H&L Flow alarm settings

- Totalizer #1 reading exceed set limit

- Totalizer #2 reading exceed set limit

- Low Temperature alarm (*T/P option only)

- High Temperature alarm (*T/P option only)

- Range between High and Low Temperature alarm (*T/P option only)

- Low Pressure alarm (*T/P option only)

- High Pressure alarm (*T/P option only)

- Range between High and Low Pressure alarm (*T/P option only)

NOTE: Your Vortex Flow Meter was calibrated at the factory for the specified fluid and full scale flow range: 4mA – 0%F.S. and 20mA – 100%F.S. (see device’s label or calibration data sheet). There is no need to adjust the Flow Meter 4-20 mA range limits settings, unless adjustment for specific range is needed.



- Diagnostic: Output will be energized when any of the Diagnostic or System events are active

- Manual On Control: Output will be energized until Disabled option will be selected.

By default both optically isolated outputs are disabled.

5.3.6.3 Submenu L2 RS-485 Address Menus

The standard Vortex flow meter comes with an RS-232 interface. For the optional RS-485 interface, two hexadecimal characters of the address must be assigned. By default each flow meter is shipped with RS-485 address 11. When more than one device is present on RS-485 bus each device should have unique address. The two characters of address in the hexadecimal representation can be changed from 00 to FF.

RS-485 address setting is not used for Vortex flow meter with RS-232 interface.

5.3.7 Submenu L1 Calibration Menu

The Calibration Menu contains the calibration coefficients for the flow meter, DSP algorithm settings and Noise Reduction Filters parameters. These values should be changed only by properly trained personnel. The Pipe ID, Vortex Meter Calibration Factor, Full Scale Range and Low Flow Cutoff are set at the factory. Consult the factory for help with these settings if the meter is showing erratic flow rate.

NOTE: Address 00 is reserved for global addressing. Do not assign, the global address for any device. When command with global address is sent, all devices on the RS-485 bus execute the command but do not reply with an acknowledge message.



NOTE: Do not assign the RS-485 address for two or more devices on the same RS-485 bus. If two or more devices with the same address are connected to the one RS-485 network, a communication collision will take place on the bus and communication errors will occur.



NOTE: Your Vortex Flow Meter was calibrated configured at the factory for the specified fluid, flowing conditions, and full scale flow range (see device’s label or calibration data sheet). There is no need to adjust the Flow Meter calibration factor, unless adjustment for specific installation or flowing conditions high or low frequency off is needed. Any alteration of the flow meter calibration factor will VOID calibration warranty supplied with instrument.



5.3.7.1 Submenu L2 PWM DSP Menu

Digital Signal Processing software algorithm can be set to calculate flow rate based on five different methods:

a) Auto b) number of pulses over preset measure interval c) PWM (pulse width measurement) d) FFT e) AWD (Analog Watchdog circuitry, for troubleshooting only)

By default Vortex Frequency source is set to Auto. In this mode flow meter automatically switching source to best suited algorithm.

All methods calculates frequency of the pulses from the flow meter sensor. The number of pulses over preset measure interval method convenient when pulsating flow or especially noisy signals are encountered. This method allows to get stable average flow rate if pulse measure interval is set to values equal or more than 2000 ms. This parameters effects the flow update rate. With higher value of the pulse measure interval, the and stability of the flow measurement improves, but response time become longer. A suggested pulse measure interval value of 2000 seconds is a good starting point for most applicable process fluids. With lower settings the response time of the meter will be shorter, but and stability will degrade. The pulse measure interval settings are only related to the number of pulses over preset measure interval method. Pulse measure interval can be selected between 500 and 60000 ms.

Parameters

The Flow Damping value can be selected between 0 and 99 seconds. The value represents the response time for a 0 - 66 % step flow rate change. When damping value set to 0 it is disabled.

A Noise Reduction Filter algorithm (running average of the individual flow inputs) is available in the flow meter when pulsating flow or especially noisy signals are encountered.

There are three parameters that make up Signal Processing Control:

- Number of Samples

- Time Limit

- Error Limit

They are described individually below.

Number of Samples [NRF]: The sample number value can be selected between 1 and 32. The number of samples value represents the number of previous individual inputs used to calculate the average value. Eventually the number of samples in the running average also affects the response time. The more samples is used, the more inertial flow output reading will be to the actual flow change. A suggested nominal number of 16 samples is a good starting point for most applicable process fluids.

Time Limit: can be selected between 0 and 99 seconds. The value represents the response time of the running average flow rate change. The higher the Time Limit the longer the response time of the filter. If noise reduction filter is not desired it may be disabled by setting Time Limit parameter to zero. By default unit shipped from the factory with Time Limit value set to 6.

Error Limit: can be selected between 0.0 and 100.0 % of full scale. The value represents the difference of the signal sample from previous measured value. Error Limit is configured to reject noise spikes within the flow range while allowing normal frequency variation of the vortex signal. The factory setting 2.0% of full scale optimizes noise rejection in most applications.

The Turbulence Flow Window parameter is used to define turbulence conditions. The value represents the difference between two consecutive measurements in % of full scale. If the difference between two consecutive measurements will be higher than value set for Turbulence Flow Window parameter, the Turbulence Event will be triggered. Default settings are 30.

NOTE: NRF settings only applicable to PWM algorithm.



The Flow Linearization algorithm may be used to improve linearity of the flow measurement. The Flow Linearization table is built during factory calibration procedure and stored in the device EEPROM. The Flow Linearizer can be used with all flow measurement algorithms. By default unit shipped from the factory with disabled Flow Linearizer.

5.3.7.2 Submenu L2 FFT DSP Menu

FFT Trigger Level is used to define lowest amplitude of the harmonic to be considered as valid vortex signal. When set to zero the FFT Trigger Level will be determine automatically as ¼ of the signal amplitude.

FFT Sample/Second defines the number of samples per second for Analog to Digital Converter (ADC) taken from a continuous analog signal to make a discreet signal. This is tabular entry. When set to Automatic mode, the sample rate will be switched automatically to keep best resolutions (default settings).

NOTE: Do not adjust FFT DSP parameter unless directed to do so by a AALBORG Technical Support Representative.

FFT Noise Threshold is configured to reject noise within the flow range while allowing normal amplitude variation of the vortex signal. Signals of amplitude lower than the Trigger Level setting are filtered out. The factory setting optimizes noise rejection in most applications.

Attenuator Target Level defines the target RMS level for the sensor signals. If Auto Attenuation is enabled the DSP algorithm will constantly adjust attenuation to keep sensors RMS output within Attenuator Target Level value. Default factory setting value (200) works for most applications.

Manual Attenuation Adjustment allows you to manually adjust the sensors RMS output individually for each sensor. This feature mostly useful only for troubleshooting procedure.

Sensor Auto Balancing procedure designed to automatically balance sensors RMS output.

5.3.7.3 Submenu Meter Size

The Meter Size or pipe I/D (for insertion type) is preset at the factory and should not be changed unless meter body or PCB electronics are replaced or meter is being installed in to the pipe with different internal diameter for insertion flow meter.

The second record of the same Event code may occur only if corresponding Event bit was reset in the flag register (for example if Low Flow Alarm conditions was activated and flow rate increased above Low Flow Alarm threshold settings).

a) Event Log Status

With this menu selection user may check how many total events are recorded in the Event Log file. The Overflow counter (OF) indicates how many times Event Log index was wrapped around back to zero. Pressing Enter key from Event Log Status screen will allow customer to list and review all recorded events. The Event record will display Date and Time on the first line of the LCD and Event code on the second. Pressing Enter key one more time will momentarily (for 2 seconds) replace Event code with detailed description of the corresponding event. Pressing UP or

DN button will allow to list all other Events in the Event Log file.

NOTE: Each Alarm Event can be individually masked (disabled) using

Event Log Mask menu selection (see Figure 5.15). If alarm event is masked (disabled) it will not be recorded in to the Event Log File, even actual event has occurred. System Events (see table 5.x) can not be

masked therefore will be always recorded in to the Event Log File.

6. ANALOG CIRCUITRY CALIBRATION

6.1 Analog 4-20 mA output Circuitry calibration

The Vortex 4-20 mA analog output calibration involves calculation and storing of the offset and span variables in the EEPROM for both output channels. The following is a list of the EEPROM variables used for analog outputs computation:

Analog Output#1 variables:

Index Name Description

32 Out1_Scale_mA - Analog 4-20 mA Output #1 Scale 33 Out1_Offset_mA - Analog 4-20 mA Output #1 Offset

Analog Output#2 variables:

Index Name Description

34 Out2_Scale_mA - Analog 4-20 mA Output #2 Scale 35 Out2_Offset_mA - Analog 4-20 mA Output #2 Offset



NOTE: The 4-20 mA analog outputs available on the Vortex Flow Meter were calibrated at the factory. There is no need to perform analog out put calibration unless the CPU or TERM PCB was replaced. Any alteration of the analog output scaling variables in the EEPROM table will VOID calibration warranty supplied with instrument.



NOTE: It is recommended to use the Aalborg

supplied calibration and maintenance software for analog output calibration. This software includes an automated calibration procedure which may radically simplify calculation of the offsets and spans variables and, the reading and writing for the EEPROM table.



6.1.1 Initial setup

Power up the Vortex Flow Meter for at least 15 minutes prior to commencing the calibration procedure. Make sure absolutely no flow takes place through the meter. Establish digital RS-485/RS-232 communication between PC (communication terminal) and Vortex flow meter. The commands provided below assume that calibration will be performed manually (w/o Aalborg

supplied calibration and mainte-

nance software) and the device has RS-485 address 11. If Aalborg

supplied calibration and maintenance software is used, skip the next section and follow the software prompts.

Where: Y – the calculated Out2_Scale_mA value.

Z – the calculated Out2_Offset_mA value.

6.2 Temperature and Pressure Sensors Calibration*

7. START UP

7.1 Cautions Prior to Start Up

In general, it is good practice to purge the line slowly to prevent unnecessary damage to the meter.

Once the pipeline is pressurized, check the flow meter and flanges for leaks.

The temperature and pressure transducers should also be checked for leaks.

The meter may give erratic outputs during purging the line if the power has been turned on before purging the line.

The Vortex flow meter does not have the capability of measuring two phase flow. In liquid applications, the line should be totally purged of air before powering the flow meter.

During start up, remember that the meter will not read accurately until the flow rate meets or exceeds the minimum flow rates stated on the I.D. sheet. The maximum and minimum flow rates for a specific flow meter can be found on the meter I.D. sheet.

NOTE: If recalibration of the Temperature or Pressure sensors is required, it is recommended to use the Aalborg

and writing for the EEPROM table.



NOTE: If your flow meter is equipped with optional Temperature and Pressure sensors, then they were calibrated at the factory. There is no need to perform Temperature and Pressure sensors calibration unless the CPU / TERM PCB or actual Temperature or Pressure sensor was replaced. Any alteration of the temperature or pressure input scaling variables in the EEPROM table will VOID calibration warranty supplied with instrument.



8. TROUBLESHOOTING

8.1 Common Conditions

Your Vortex Flow Meter was thoroughly checked at numerous quality control points during and after manufacturing and assembly operations. It was calibrated according to your desired flow and pressure conditions for a given fluid. It was carefully packed to prevent damage during shipment. Should you feel that the instrument is not functioning properly, please check for the following common conditions first:

Are all cables connected correctly?

Are there any leaks in the installation?

Is the power supply correctly selected according to requirements?

When several meters are used a power supply with appropriate current rating should be selected. Were the connector pinouts matched properly?

When interchanging with other manufacturers' equipment, cables and connectors must be carefully wired for correct pin configuration.

8.2 Troubleshooting Guide

NO. INDICATION LIKELY REASON SOLUTION

1 LCD Display

remains blank when unit is powered up. No response when flow is introduced from analog 4-20 mA.

Power supply is bad or polarity is reversed.

Measure voltage on pins 1 and 2 of the TB1 screw terminal connector. If voltage is out of specified range, then replace power supply with a new one. If polarity is reversed (reading is negative) make correct connection.

PC board is defective.

Return flow meter to factory for repair.

2 LCD Displays flow

reading, but 4-20 mA output signal does not change (always the same or reading around

4.0 mA).

Volumetric or Mass Flow PV is no assigned to corresponding 4-20mA output

Using Key Pad, navigate to Submenu L1 “Output Menu” and select one of the Submenu L2 options: “4-20mA Output1” or “4-20mA Output2” (see paragraph 5.3.6.1). Make sure that parameter “4-20mA Output1 Mode” or “4-20mA Output2 Mode” is set to Volumetric or Mass Flow.

External loop is open or load resistance more than 600 Ohm

Check external connections to pins 1 and 2 (for channel #1), 3 and 4 (for channel #2) of the TB3 screw terminal connector. Make sure the loop resistance is less than 600 Ohm.

Flow output 4-20 mA schematic is burned out or damaged.

Using Key Pad, navigate to Submenu L1 “Diagnostic Menu” and select “Submenu DAC Outputs”. Record the #1 and #2 counts values and consult the factory with findings.

3 Fluid flows

through the Vortex flow meter, but LCD Display reading and the corresponding 4-20 mA flow output signal do not respond to flow.

The fluid flow rate is below set Low flow cut-off value. Sensors or PC board is defective.

Check settings for Low flow cut-off value and make required adjustment (see paragraph 5.3.7.6 “Submenu Meter Low Flow Cut Off”).

Using ESD precautions and hazardous area precautions, remove the electronics enclosure window cover. Remove electronics assembly unit. Disconnect the vortex sensor connector from the CPU board (the CPU board is the board with LCD display) via cut out in the terminal board. Measure the resistance from each outside pin to the center pin (meter ground) – each should be open. Measure the resistance from the center pin to the meter ground (metal enclosure or pipe) – this should be grounded to the meter. With the sensor connector still disconnected from PCB, using Key Pad, navigate to Submenu L1 “Diagnostic Menu” and select “Pulse Frequency” or “PWM Frequency” screen. Hold a finger on the metal part of the small screwdriver and touch exposed outside pins of the sensor connector on the CPU board. The meter should read electrical noise, 60 or 50 Hz for example. If it is true, re-install vortex sensor connector back and check flow meter with flow conditions. If necessary contact factory for additional help.

NO. INDICATION LIKELY REASON SOLUTION

4 There is no actual

fluid flow through the Vortex meter (no flow conditions), but LCD Display reading some flow rate.

Sensors wires are disconnected from CPU board.

Make sure two wires from the sensor are firmly attached to outside pins of the connector and wire from the center of the connector is attached to the grounding terminal screw inside of the electronics assembly enclosure.

Vortex flow meter not properly grounded.

Make sure flow meter enclosure case (external Grounding terminal) is directly connected to earth ground with minimal impedance (see pages 105-107).

Flow Meter is too sensitive to the external noise or vibration.

Using Key Pad, navigate to Submenu L1 “Diagnostic Menu” and record following parameters: “FFT Output”, “FFT Average”, “Sensors RMS” and consult the factory with findings.

5 Erratic Flow rate

Reading

The flow rate may be too low, just at the cutoff of the meter range, and the flow cycles above and below the cutoff making an erratic output.

The meter range is provided with product label attached to the meter body (based on customer’s application flowing conditions when the meter was ordered). Consult the factory if necessary to confirm the meter range based on current operating conditions. It may be possible to lower the low flow cutoff to increase the meter range.

Mechanical installation may be wrong.

Verify the straight run is adequate as described in Paragraph 3.3 “PIPING GUIDELINES”. For in-line meters, make sure the meter is not installed backwards and there are no gaskets protruding into the flow stream. For insertion meters, verify the insertion depth and flow direction.

The meter may be reacting to actual changes in the flow stream.

The displayed flow rate values can be smoothed using the Flow damping and NRF time constant parameters in the PWM DSP Menu (see paragraph

5.3.7.1).

NO. INDICATION LIKELY REASON SOLUTION

6 The Temperature*

reading on the LCD is not correct (out of the device measurement range: -20 to 260C) * - for devices with T/P option.

RTD connector got loose and is not connected to the PCB board.

Check RTD connector on the terminal PCB, make sure it is firmly attached to the header J3.

RTD sensor is defective

With power applied to the flow meter, navigate to Submenu L1 “Diagnostic Menu” and select “T/P ADC Out” menu option. The T value should be around 840 counts at room temperature (20 - 25 °C). Using ESD precautions and hazardous area precautions, remove the electronics enclosure window cover. Remove electronics assembly unit. Disconnect the RTD temperature sensor connector from the header J3 on the terminal board. Measure the resistance across the outside pins of the temperature sensor connector. It should read approximately 109 ohms at room temperature (higher resistance at higher temperatures). Contact factory with finding.

7 The Pressure*

reading on the LCD is not correct (out of the device measurement range or does not react on pressure change in the process line) * - for devices with T/P option.

Pressure sensor connector got loose and is not connected to the PCB board.

Check pressure connector on the terminal PCB, make sure it is firmly attached to the header J2.

Pressure sensor is defective

With power applied to the flow meter, navigate to Submenu L1 “Diagnostic Menu” and select “T/P ADC Out” menu option. The P value should be around 900* counts at ambient pressure (14.7 PSIA) * this value only applicable for pressure sensor with full scale range 100 PSIA. Consult factory if your flow meter has different pressure range.

8 The Flow Meter

Diagnostic Alarm Event with code 0 – “CPU Temp. High” is active.

MCU temperature is too high (overload).

Disconnect power from the Vortex flow meter. Make sure the ambient temperature is within specified range (below 65 °C). Let the device cool down for at least 15 minutes. Apply power to the flow meter and check Diagnostic Alarm Event. If overload condition will be indicated again the unit has to be returned to the factory for repair.

9 The Flow Meter

System Event with code 24 - “Fatal Error” is active.

Fatal Error (EEPROM or SRAM corrupted)

Cycle the power on the Vortex flow meter. If System Event with code 24 indicating again the unit has to be returned to the factory for repair.

VORTEX METER ASCII COMMANDS SET Rev. 07/29/2010

RS232/RS485 The standard VORTEX METER comes with an RS232 interface. The protocol described below allows communication with the unit using

either a custom software program or a “dumb” terminal. All values are sent as printable ASCII characters. For RS-232 interface, the start character and

two characters of address have to be omitted. For the RS485 interface the start character is always ‘!’ and two characters of address are follow. The com-

mand string is terminated with a carriage return (line feeds are automatically stripped out by the VORTEX METER:

RS-485: !<Addr>,<Cmd>,Arg1,Arg2,Arg3,Arg4<CR> Example: !12,VF<CR>

RS-232: <Cmd>,Arg1,Arg2,Arg3,Arg4<CR> Example: VF<CR>

Where: ! Start character **

Addr RS485 device address in the ASCII representation of hexadecimal (00 through FF are valid).**

Cmd The one or two character command from the table below.

Arg1 to Arg4 The command arguments from the table below. Multiple arguments are comma delimited.

CR Carriage return character.

** Default address for all units is set to 11 hex. Do not submit start character and device address for RS-232 option.

Several examples of commands follow. All assume that the VORTEX METER has been configured for address 18 (12 hex) on the RS485 bus:

1. To get a volumetric flow reading: !12,VF<CR>

The device will reply: !12,50.0<CR> (Assuming the flow is at 50.0% FS)

2. To get current Flow Alarm status: !12,FA,S<CR>

The device will reply: !12,FAS:N<CR> > (Assuming no alarm conditions)

3. To get Totalizer#1 reading: !12,T,1,R<CR>

The device will reply: !12,T1R:93.5<CR> (Assuming the Totalizer#1 reading is 93.5)

4. Set the volumetric flow high and low alarm limit to 90% and 10% of full scale flow rate: !12,FA,C,V,90.0,10.0<CR>

The device will reply: !12, FAC:V,90.0,10.0<CR>
