1.1 Operating Principles

1.2 Transit Time Operation

Page 5

1.0 Product Overview

The Hybrid Ultrasonic Flow Meter can measure fluid flow in virtually any fluid in which sound waves can travel. The meter is considered “hybrid” because it can measure fluid flow using either the Doppler or Transit Time methods. The system includes a set of ultrasonic sound Transducers and a Signal Processing Unit (SPU). The transducers are clamped to the outside of the pipe wall and include no moving parts. The SPU controls and processes the transducer signals into useful flow measurement data. This method of flow measurement is safe, non-intrusive and very easy to service.

The Transit Time measuring method requires relatively “clean” fluid to enable the sound waves to complete their circuit. The meter may be operated in the Transit-Time mode when the fluid contains particles. To allow for changes in the fluid’s particle count, the Sonic-Pro monitors the signal gain and employs an Automatic Gain Control (AGC) algorithm that automatically adjusts the gain to maintain the optimum power level.

The speed at which sound travels in the fluid must be known. The factory will configure the meter for a known fluid during the initial configuration. The model 3 includes a 5button user interface that can be used to configure the meter. Many common fluids are listed in the software and can be selected directly from the menu. Provided the speed of sound in the fluid is known, custom “unknown” fluids can be input manually by the user. A list of various fluids and their sound speeds are provided in the index of this user manual.

0% to 10% (0 to 100,000 ppm) of

TRANSIT TIME MEASUREMENT PRINCIPLE

When operated in the Transit Time measurement method, a short ultrasonic signal burst passes first in one direction and then in the other between two transducers separated along the length of the pipe. When traveling in the same direction as fluid flow, the burst is carried along by the fluid and arrives earlier as a result. When traveling against fluid flow, the burst is held back by the fluid and arrives later. The SPU (

measures this difference in time-of-flight in the two directions. From this, the

Unit) actual time-of-flights, the distance traveled in the fluid and the angle of the ultrasonic signal path, it calculates the fluid velocity.

As well as the V mounting method shown, the transducers could be on opposite sides of the pipe with no reflections in the path (Z mount).

Signal Processing

1.3 Doppler Operation

The Doppler measurement method requires that particles be present in the flow stream to “reflect” the sound waves. The particles must be of sufficient size, volume and type to reflect the sound waves. For example; although orange juice may contain pulp that is of sufficient size and volume, the properties of the pulp do not allow the sound waves to reflect. Therefore, the meter will not operate in the Doppler mode with orange juice containing pulp.

The meter may be operated in the Doppler mode when the fluid contains (200 to 150,000 ppm) of sound reflection properties.

particles that are at least 50 micron in size and have sufficient

0.02% to 15%

DOPPLER MEASUREMENT PRINCIPLE

When operated in the signal passes from a transmitting transducer into a pipe carrying a moving fluid. The signal is reflected by particles in the fluid and is picked up by a receiving transducer on the opposite side of the pipe.

When using the Doppler method, the transducers are installed directly opposite each other along the pipe axis, one each side of the pipe, either with or against the flow of fluid. The ultrasonic signal is subject to a Doppler shift when it is reflected from the particles moving at (nominally) the same velocity as the fluid. Therefore, the frequency at the receiving transducer will be slightly different from the transmitted frequency. SPU (

Signal Processing Unit) measures this difference in frequency and calculates the

fluid velocity.

Note that the meter is actually measuring the velocity of the particles and not the actual fluid. For this reason, measurement error will occur if the particles do not move at the same velocity as the fluid, such as when the particles are heavier than the fluid or when the fluid is moving at such a low velocity that the particles drop out of suspension. Large “gulps” of air or particles will temporarily disrupt the flow measurement resulting in error.

Note: The sound wave beam is only affected by fluid that actually passes through the beam and therefore, the meter will not measure with high accuracy if the fluid velocity is not consistent across the entire pipe diameter. Flow disturbances such as pumps, elbows, tees, and valves in the flow stream can cause swirl patterns and vortices that will affect the measurement. Install the transducers on a straight run of pipe as far as possible from any disturbances. The distance required for high accuracy will depend on the type of disturbance.

4.5 Transducer Positioning State

In the Transducer Positioning State, the flowmeter waits for the transducers to be correctly positioned on the pipe.

When operated in the Transit Time measurement mode, the separation distance of the transducers is computed by the flowmeter from the information in the Transducer Setup branch of the Configuration Menu. The correct separation distance is dependent on the pipe OD, pipe wall thickness, pipe type and chosen mounting mode. If the Doppler measurement mode is selected (by the motherboard switch), the separation of the transducers (along the pipe axis) is always zero.

When factory configured, the separation distance and mounting mode is printed on the serial label. The separation distance will also be displayed on the LCD display or on the optional communications PC software, in either inches or millimeters depending on the Measurement Units chosen in Transducer Setup. If the meter has not been factory configured, or if a new configuration is required, the pipe OD, pipe wall thickness, pipe type, fluid type and chosen mounting mode configuration data must be input before proceeding. See section 5.3 for instructions on how to create or modify a configuration.

If the flowmeter has neither an LCD display nor a connected user PC Software application, then the Configuration information cannot be changed by the user so the separation of the transducers will not change from the factory setting.

The flowmeter indicates that it is in the Transducer Positioning State as follows:

Model 1: two center yellow LEDs flash at 1 Hz.

4.6 Zero Calibration State

If the Transit Time measurement mode is selected, a zero calibration should be performed if possible. calibration. It is not necessary to perform zero calibration if Doppler measurement mode is selected, however it is harmless and will have no effect on the measurement.

In the Zero Calibration State, the flowmeter measures and records the apparent rate of fluid flow to offset measurements in Run Mode and compensate for any zero flow error. This information is associated and stored with the active Configuration Set and survives power loss and restarts. If a new Configuration Set is made activate, it will have its own zero calibration information. Therefore, the calibration must be performed after the configuration is created and saved. Although the zero calibration is not required, positive or negative zero offset reading error may result if the calibration is not performed.

The approximate duration of zero calibration is 15 to 20 seconds. movement of fluid in the pipe. Do not perform zero calibration if it is not possible to establish zero fluid flow in the pipe. If there is flow during zero calibration, then flow measurement in Run Mode will be inaccurate. The only means provided to cancel zero calibration or to undo its effect is to perform another zero calibration.

Zero calibration must be started while in the Startup State by holding down the SETUP button for at least 3 seconds. The Startup State may be entered by power cycling the flowmeter or upon exit from the Setup Mode or Transducer Positioning state. With either the Model S3 display or the optional Communications Board and a connected Host PC, the Setup Mode can be activated directly from the Run Mode by pressing the SETUP button and then the pressing the ESC button.

Faults and Warnings will be identified by two-digit error codes.

! A Fault will cause the meter to discontinue flow measurement. Note that the 4-20mA

analog output signal and 0-1000 Hz pulse output signal sets to the minimum values (fail safe low), and all relays will respond as if in a zero flow condition.

! A Warning will not interrupt flow measurement, output signals, or relay functions.

The fault LED will flash at a rate of 2 pulses per second (ON for 250 ms and OFF for 250 ms) to count out the first digit of the error code, will then stay OFF for 1.25 second, will then flash again to count out the second digit and then stay OFF for 5 seconds. The code will repeat. are available. The errors that can occur and their assigned codes are listed below.

The Faulted state will attempt to self correct, however, if the error is due to a configuration problem such as impossible pipe geometries, the configuration error must be corrected before the fault condition will clear. Repositioning the transducers may be required before the fault can correct itself. A fault that is caused by an empty pipe condition, excessive air or particles in the fluid, or other such flow stream disturbances will self correct when the flow stream returns to an acceptable condition.

Attempting Correction.....

MODEL 2 and MODEL 3

The Fault and Warning codes and their respective numbers are listed below. See the troubleshooting guide in the index of this manual for more information about correcting for errors.

Fault Codes

F15 Transit Time: Burst onset not detected F13 Transit Time: Measured sound speed exceeded the configured allowable limit F19 Improbable flow rate over 40 feet per second (12 meters per second) F81 Receive signal too weak or absent during burst accusation F91 Impossible pipe geometries

Warning Codes

W11 Receive signal near lower limit of operation W12 Receive signal too strong W13 Transit Time: Measured sound speed exceeded the configured allowable limit W16 Transit Time: Burst onset not detected W17 Transit Time: Periodic burst onset detection has large decrease in confidence W18 Transit Time: Large gain in periodic receiver gain adjustment detected W37 Improbable scaling offset (e.g. less than 0.5 or greater than 2.0)

The user can configure a fluid sound speed limit value. This feature can be used to monitor the fluid and alert the user to changes in fluid density. Should the measured sound speed be greater then the acceptable percentage of error, error code 13 will be recorded. Error code 13 can be configured to result in either a fault condition or a warning condition. The default setting is recorded as a fault. See section 5.4.3 for more information on this feature.

If the ESC soft button is pressed repeatedly to go back up in a menu until the top level is reached and is then pressed one time more, the flowmeter “escapes” from the Setup Mode directly to the Startup State and from there to the Run Mode, as described in section 4.4 above. The Configuration Set used is the same as was previously selected. If no changes were made to this Set, for example if a different Configuration Set was changed, the flowmeter will operate exactly as before. However, if the active Set has been opened, edited and saved, then the changes will take effect without the re-calculation of internal parameters and therefore the flowmeter may not operate correctly.

5.2.2 Master Password

On selecting this action, you are prompted to supply a Master Password. The master password is “empty” when shipped from the factory. The first time user may enter any master password. Once entered, this master password can be used to enter

ANY configuration, as if no other passwords are present.

Once a Master Password has been entered, upon selecting this action, you will

prompted to supply the Master

flowmeter returns to the Setup Root Menu. If it is done correctly, you are given the choices of changing the Master Password or returning to the Setup Root Menu. If you elect to change the Master Password, you must enter it twice. You will

receive confirmation of the change or, if the

two entries were not the same, the password will not change and, in either case you are returned to the Setup Root Menu. Whether the Master Password is changed or not, on return to the Setup Root Menu, you will not need to enter passwords for the duration of the current Setup Mode session.

Wherever a password is required, the Master Password will be accepted. Therefore, knowing the Master Password lets you do anything. In particular, you can overwrite “forgotten” passwords. Knowing just the password of a single Configuration Set lets you edit, activate or delete only that set.

5.2.3 Setting the Date and Time

5.3 Manage Configuration Sets

Under the Manage Configuration Sets menu item, the user is offered actions to manage these Sets in much the same way as files on a computer.

Activate a Configuration Set allows the user to apply a Configuration Set to the flowmeter, which will then enter Run Mode and operate according to the configuration information in that Set plus the setting of the motherboard measurement mode switch.

Open a Saved Configuration Set allows the user to inspect and edit a Configuration Set, reset it to the Factory Configuration, save changes to it, save it to a different Set, etc. Create a New Configuration Set begins a fresh Configuration Set, starting from the pre-set Factory Configuration.

Delete a Saved Configuration Set removes a Configuration Set from the flowmeter.

Similar to operating on files in a computer, the editing of a Configuration Set takes place in a temporary location called the “Working” Set. This must be saved by the user, either back to where it came from or to a different numbered Set, otherwise it will be lost if the flowmeter loses power or the user escapes from Setup Mode.

On selecting this action, a list of the pre-saved Configuration Sets will be shown. The user can select a Configuration Set using the and soft buttons and press the ENTER soft button to activate that Set. The flowmeter then exits the Setup

Mode to the Transducer Positioning State and eventually the Startup State

and then to the Run Mode where it will perform flow measurement using the configuration data of that Set.

The Setup Root Menu will return to the screen without the activation of a Configuration Set if the user fails to supply a password (if required), or presses the ESC soft button twice.

This action is similar to Activate a Saved Configuration Set in that the user is able to select and open a valid Configuration Set. On pressing the ENTER soft button and supplying a password if necessary, the selected Configuration Set will be loaded into the Working Set and the Configuration Edit Menu will appear. From this screen, the user can navigate to and edit configuration items.

On selecting this action, the pre-set Factory Configuration data will be loaded into the

Working Set and the Configuration Edit Menu will appear. The banner will read New Configuration Set. From this screen, you can navigate to and edit configuration

items and save the configuration to a numbered Set.

Deleting a Configuration Set starts out the same as Activate a Saved Configuration Set. On pressing the ENTER soft button and supplying a password if necessary, the Configuration Set number and data will be deleted. Note that new configuration data can now be saved to that numbered set). If all Configuration Sets are deleted, the flowmeter will operate according to the Factory Configuration.

The Working Configuration set cannot be directly activated. It must first be saved (to a numbered Set). Actions do not appear in the menu if they are inappropriate (for example, Save and Save and Activate do not appear for a new Set until it is saved to a Numbered Set).

There are two possible ways to change editable data in the flowmeter. From the user PC software, decimal digits can be typed directly. From the flowmeter, the user is limited to the five soft buttons. Data is not available for editing in Model 1 and Models 2 without the user PC Software application.

5.4.1.1 Editing Numerical Values

If you press the ENTER soft button when the highlight is on a leaf item that has a editable value (rather than a list of choices), you can then edit the value, one digit at a time. The current value is displayed to an appropriate precision and the leftmost digit is highlighted (see example below).

Using the soft button, the value of

the highlighted digit can be increased by one for each press. Upon reaching 9, it wraps to

0. Using the and soft

Buttons, the highlight can be moved to the left or right one digit at a time. The highlight skips non-editable positions, such

as the decimal point. If the highlight is moved beyond the leftmost digit, a new digit will appear with the value 0. If this digit is not changed before the highlight is moved

ENTER

ESC

back to the right, it will be removed. A similar procedure can be used to add zeros to the right of the number, but only if the number is a real number (contains a decimal point).

When the ENTER soft button is pressed, the currently displayed value becomes the new value of the item being edited and the menu system moves one place back, appearing as it did before the edit began. If the ESC soft button is pressed, then the menu system also moves one place back but the value of the item is not changed and remains as it was before the edit.

5.4.1.2 Entering Passwords using the Soft Buttons

All passwords must contain 5 digits. Each of the five soft buttons represent 2 digits. The numbers 5, 6, 7, 8 and 9 are interchangeable with 0, 1, 2, 3 and 4 (respectively), so only five choices are needed to enter any digit from 0 thru 9. Entering the number 00000 (55555) effectively cancels the password

flow units can be configured for U.S. Barrels Liquid. Note that total units do not include

time as a variable.

When entering data in the , any value associated with rate of flow must be entered in the units of measure that is currently configured at the time the data entry takes place.

Metering Setup and the Process Control Setup screens

rate of flow

Any value associated with the total flow must be entered in the total flow units of measure configured at the time the data entry takes place. This requirement does not apply to values in the Transducer Setup branch, (such as pipe sizes) which are governed by a separate selection of units of measure (see section 5.4.2 below). When entering data by making a selection from a list, it is not necessary to be aware of the units of measure in force.

For example, if in Flow Rate Volume Units you chose U.S. Gallons and in Flow Rate Time Units you chose Hours, then Log Rate Setpoints must be entered in U.S. Gallons per Hour. Similarly, if in Flow Total Volume Units you chose U.S. Barrels Liquid, Log Total Setpoints must be entered in U.S. barrels liquid.

If the configured units of measure are changed, all editable data item displays will automatically change to the new units, but they will represent the same actual quantities. This happens because the flowmeter converts and stores these data values in SI units.

measurement. This is done when a Configuration Set is “activated”, but not when a user exits Setup Mode by “escaping” (for example, after the five minute timeout). Note that changes in this area of configuration followed by an escape from Setup Mode may cause the flowmeter to display incorrect flow information.

Under the Transducer Setup branch, the following actions are available:

Measurement Units allows you to specify whether dimensions will be entered in inches and the speed of sound in feet-persecond (English) or dimensions will be entered in millimeters and the speed of sound in meters-per-second (Metric). This choice and all entered numbers must be consistent when a Set is activated. If, for example, the pipe diameter is entered as

2.00 when English units are selected but the choice is then changed to Metric, it is necessary to go back and enter 50.8 as the pipe diameter or the flowmeter will attempt to configure itself for a pipe which is only 2 millimeters across (and will fault).

Transducer --> Model Number allows you to specify the model number of the transducer pair used. You should not change this setting unless you use a different transducer pair from that originally supplied. The transducer model number (A00 through A20) is printed on the transducer housing.

6.4 Transducer Separation Distance

When the meter is operated in the Doppler measurement method, the transducers are ALWAYS mounted directly opposite each other. The separation is therefore zero.

When the meter is operated in the Transit-Time measurement method, the front faces of the transducers must be positioned the correct distance apart.

Separation

Distance

The correct separation distance is dependent on the pipe size, pipe type and chosen mounting mode. When factory configured, the separation distance and mounting mode is printed on the serial label. If the meter has not been factory configured, or if a new configuration is required, the configuration data must be input before proceeding. See section 5 for instructions on how to create or modify a configuration.

Transit Time V mounting method:

If the fluid contains little or no particles (up to 10% maximum), operate the meter using the Transit Time method to obtain the best accuracy.

When the meter is operated in the Transit Time method, marking the second transducer location is required.

The V Mount mode requires careful separation distance measurements. Inaccurate placement of the transducers may result in insufficient signal strength and poor measurement accuracy.

Draw a straight centerline, parallel to the center line of the pipe, from the first transducer location mark (A) through to the second transducer location (B). Place a mark on the centerline at the correct transducer separation distance.

6.9 Transducer Acoustic Mounting Gaskets

An acoustic coupling material must be placed between the transducer and the pipe surface at the point where the sound waves enter the pipe.. Without this material, the ultrasonic sound waves will not penetrate into the pipe. The meter package includes three different gasket materials for this purpose.

The blue gasket should be used for permanent installations. This gasket will be damaged be repeated installations.

The white gasket should be used for non-permenant installations such as in portable applications. This gasket will withstand multiple installations.

Dow Corning Silicone Seal #111 may be used in place of the gaskets if desired.

7.0 Run Mode

This section describes the flowmeter operation in the Run Mode. A mock-up of the Run Mode screen is shown at right. This is how it appears for Model 2 and 3 Displays or if it is viewed from the User PC Software application . For Model 2, the only difference is that the SETUP and RELAY soft buttons are absent (blank) on the flowmeter display (but they are still present at the PC).

In the Run Mode, the flowmeter measures the velocity of fluid movement in the pipe and from this, and the user-specified dimensions of the pipe, determines the volumetric flow rate and accumulates the total volume of fluid flow. The flowmeter is not sensitive to the direction of fluid movement and flow in either direction is treated as positive for both flow rate display and accumulation of the total volume of fluid that has passed (totalization). Should fluid flow first in one direction and then return in the other direction, the flowmeter will register a total of twice the amount of fluid, even though the net actual flow is zero.

Two display areas are provided to show the current flow rate and the total accumulated flow. Both areas can display ten digits and the decimal point.

You may configure the number of digits that appear after the decimal point in each display area (see section 5.4.3 above). Digits remaining (from the maximum of ten) are available for digits to the left of the decimal point. Leading zeros are not shown. If it is not possible to display the value as configured, for example if only five digits are available to the left of the decimal point and the value reaches 100,000, then the display automatically switches to engineering notation. Seven significant digits are displayed followed by “E” a two digit exponent value. Example: 2.09E12

Pressing and holding the SWAP soft button a again changes the flow rate display back to the units of measure as specified in section 6.3.3. This soft button is present on Model 2 and Model 3 displays.

Pressing the CLEAR soft button zeros the total accumulated flow reading, in whichever display area it is showing. The previous total is lost and flow now accumulates in a new total. This soft button is present on . This feature can be disabled by configuration, in which case the CLEAR soft button will not appear.

7.1.1 Flow Rate Measurement

The rate of fluid flow in the pipe is measured by the flowmeter many times per second. To improve accuracy and the stability of the display, these measurements are averaged over a configurable time and new values are presented to the display at a configurable rate.

The averaging algorithm used is the Simple Moving Average (SMA), which is “the unweighted mean of the previous n data points”. Rather than selecting n, you can configure Flow Rate Averaging to be performed over some number of seconds. All measurements taken during that period are averaged to form each displayed flow reading. The averaging time can be configured by selecting a value of 0.25, 0.5, 1, 2.5, 5 or 10 seconds from the list

The time period at which the flowmeter display updates is configurable in Setup Mode to 0.25, 0.5, 1, 2.5 or 5 seconds. Each time the display is updated, the SMA of the flow measurements is computed and written to the display as described above. Setting the display update period to be much greater than the averaging time may not make sense. For example, averaging over one second and updating the display every five seconds will mean that 80% of the measurements taken will never contribute to a displayed flow value. The flowmeter does not prohibit or warn against such inconsistent settings.

The units of measure for flow rate can be configured in Setup Mode. The units in which both volume and time are expressed can be selected from appropriate options. A custom unit of measure for volume can be selected by specifying the size of one U.S. Gallon in that unit.

You you

may wish to suppress the display of very small flow values. The can configure a Low Flow Cutoff value so that if the flowmeter would display a value smaller than this, it displays zero instead. By symmetry, the user can configure a High Flow Cutoff value. If the flowmeter would display a value larger than this, it displays the cutoff value instead. Note that these values are entered in the Setup Mode as numbers and must be given in the units of measure configured for flow rate display. If at some later time change the units of measure, the cutoff values will upon inspection appear to have changed, but will represent the same flow rate, just in different units of measure.

Should observe that the flowmeter’s readings are consistently in error by a measurable amount, it is possible to correct this situation by configuring a Scaling Offset. The Factory Default for this is 1.00. The flowmeter will accept values from 0.00 to 9.99. Every measurement taken by the flowmeter is multiplied by this number before further processing. Flow rate and flow total will therefore be affected. The Scaling Offset is part of a Configuration Set, so it does not apply to the flowmeter as a whole and should be set as required in each numbered Set.

If flow measurement is restarted (by passing through the Startup State, for whatever reason), then all prior measurements previously stored for the purpose of averaging are discarded. A new average is computed using only new flow measurements and they begin to arrive after the restart. The display area in which the flow rate appears is blanked (made empty) until the first measurement is made and the first average is computed.

7.1.2 Total Flow Measurement

7.2 Measurement Status Areas

7.2.1 Configuration and Mode

As well as averaging measurements to display flow rate, the flowmeter totals all measurements divided by the measurement period to compute a totalized flow. This is written to the display at the same configured intervals as for flow readings.

The units of measure for total flow can be configured independently of flow rate.

Pressing the CLEAR soft button zeros the total accumulated flow if this option has been enabled by the configuration.

Should the flowmeter experience a power loss or be restarted by entry into Setup Mode, it will preserve a recent value of the total flow and restore this when next entering Run Mode. In Run Mode, the Total Flow will be saved to non-volatile memory every ten seconds. Any fluid that flows while the flowmeter is not in Run Mode is not included in the total.

The top line of the Run Mode screen shows the status of the measurement process. On the far left is shown the active Configuration Number, active Measurement Mode and the Transducer Separation Distance. In the center is shown the Goodness of Measurement index. On the right is shown the Speed of Sound in the fluid (if in transit time mode).

The field on the top left displays the active Configuration Set , the measurement method in effect (T for Transit Time or D for Doppler) and the transducer separation distance. The display shown to the right indicates:

! Configuration Set #1 ! Transit Time measure method ! 2.46 inches separation distance.

The measurement method can be changed by the two-position switch on the controller motherboard (the wiring access door must be removed to get at this switch) whereupon the flowmeter will automatically enter Setup Mode.

7.2.2 Goodness of Measurement

Ultrasonic Flowmeter

In Transit Time mode, the transducer separation distance shown is the distance used in Transducer Positioning, see section 2.8 above. In Doppler mode, this display value will always be zero. In both modes, the units of measure will be for the distance selected in the Transducer Setup menu, see section 5.4.2 above. If English (U.S. units) is selected, then the units displayed will be in. for inches. If Metric (SI units) is selected, then the units displayed will be mm for millimeters.

The field in the top center of the display status line displays the “Goodness of Measurement” which indicates the reliability of ultrasonic flow measurement under the present working conditions. This is computed by the algorithms that determine fluid velocity. The average of all samples computed during each display update interval is taken and then displayed as a reliability index of 0 to 4 bars. Zero bars indicate an unreliable measurement and four bars indicate high reliability.

The same goodness of measurement indication appears on the four amber LEDs on the controller motherboard, which can be viewed if the wiring access door is removed.

If flow measurement is restarted (by passing through the Startup State), then prior goodness of measurement information is discarded and the display will show zero until new information is computed.

7.2.3 Sound Speed Display

7.2.4 Measuring the Fluid Sound Speed

The field on the top right displays either a speed of sound measurement value (if in Transit Time mode) or a zero (if in Doppler mode).

When operated in the transit time mode, the flowmeter periodically calculates the speed that sound is traveling through the fluid and displays the resulting value in meters per second. This value is useful for determining the reliability of the measurement and also for configuring the meter for unknown Custom Fluids. are available for selection in the meter and their sound speed is shown the end of this manual. Should the displayed value not match, one or more of the following conditions may exist:

! The transducers are not positioned correctly ! The pipe material

Transducer Setup configuration menu The pipe wall thickness is other than specified in the Transducer Setup

configuration menu

! The fluid type does not match the Fluid Type specified in the Transducer Setup

configuration menu

! The fluid’s temperature is different than the temperature of the index values

See section 7.2.4 below for information on Fluids.

The following outlines how to use the flowmeter to determine the speed of sound in a fluid. For the flowmeter to function, the precise speed of sound does not need to be known in advance. However, to place the transducers in the optimal location, knowing the speed of sound in the fluid is important. The following outlines a procedure that you can follow in determining the fluid speed of sound.

The displayed value should closely match the fluid’s sound speed.

! This test can be performed with or without flow. It is recommended that the test be

performed with zero flow.

! The pipe outer diameter and wall thickness should be known precisely. It is

recommended to use a small section of pipe so that the exact dimensions can be measured.

! The speed of sound calculation is also affected by transducer placement. Any error in

the spacing of the transducers will translate to an error in the calculated speed of sound.

1) Enter all the appropriate information for pipe material and dimensions.

2) Select “custom” as the fluid type and enter a custom speed of sound for the fluid in meters/second. Use a best first guess – if it's a water based fluid, start with something close to the speed of sound for water. If it's an oil based fluid, use something close to the speed of sound for oil. See the index for sample fluid sound speeds.

3) Save and activate your configuration. Place the transducers at the spacing specified by the meter. Press DONE. The meter will now calculate and display a speed of sound in the upper right hand corner. If the displayed speed of sound matches that which was entered, then that value should be used. If the displayed speed of sound is different, or a fault occurs, change the fluid speed of sound to the displayed value or try a new estimate and repeat step 3.

When estimating the sound speed, use a systematic approach by increasing or decreasing your estimate by a fixed value, such as 100 meters per second.

During the run mode, the displayed speed of sound should closely match the entered speed of sound (provided proper transducer placement and no change in temperature or properties of the fluid such as density).

7.3 Process Control Status Areas

7.4 Soft Buttons

If the flowmeter is fitted with the Process Control Board, three Process Control Status Areas appear on the display under the secondary display area and above the soft button

labels. The Model 2, Model 3 and the User PC Software display is the same. Each area is labeled with the relay number to which it refers and shows the status of that relay channel. If a relay channel is disabled in configuration, the corresponding status area will be blank.

For channels configured to monitor flow total, the Process Control Status Area shows IDLE, ACTIVE or PAUSE, corresponding to the state of the channel. ACTIVE is displayed in white-on-black. For detailed information on the operation of relay channels monitoring total, see section 8.2 below.

For channels configured to monitor flow rate, the Process Control Status Area shows ALARM or CLEAR. ALARM is displayed in white-on-black and corresponds to the channel states ALARMING, ALARMED and CLEARING (that is, when the flow rate is outside the set limits or an alarm condition has been latched, whether the relay itself is energized or not). CLEAR is displayed in normal black-on-white and corresponds to the CLEAR state of the channel, when the flow is within the limits and no alarm is latched. For more information about channel states, see section 8.3 below.

In addition to the SWAP and CLEAR soft buttons, discussed above, two other soft buttons will be present under certain circumstances. Buttons that are not present appear blank.

The SETUP soft button will be present on Model 3 and also at a User PC Software connection if fitted. Pressing the SETUP soft button causes the flowmeter to enter Setup Mode and the Setup Mode Screen replaces the Run Mode Screen, see section 6 above for details. Operation of the flowmeter is immediately disrupted as flow measurement does not take place in Setup Mode.

7.5 Output Signals

7.5.1 Analog Signal Output

The RELAY soft button will also be present if the conditions above for the SETUP soft button are met and the Process Control board is fitted but not if all relay channels are disabled in configuration. Pressing the RELAY soft button causes the Process Control Screen to replace the Run Mode Screen, see section 8.1 below for details. The flowmeter at first continues to operate normally, although the user can no longer see the information displayed on the Run Mode Screen, but some actions that the user can take on the Process Control Screen will disrupt measurement.

The flowmeter provides two output signals that represent the flow rate. An analog output represents the flow rate as a current amplitude. A digital pulse output represents the flow rate as a pulse frequency. These signals will have their values (current and frequency) changed to the same values and at the same period as the flow display. In other words, they are affected in the same way by the configured averaging time, display update period and cutoffs.

The analog signal output has a current range of 4 to 20 mA. The correspondence of current to flow rate can be configured by specifying two (flow rate, current) points. Low and high flow rates, which must not be the same, are specified and the currents corresponding to each are given. Other flow rates are mapped to currents using a straight line through the points specified. The current for the high flow rate may be smaller than the current for the low flow rate, in which case the current will decrease with increasing flow rate. Flow rates mapping to currents outside the available range will cause the signal to saturate at the closest limit.

Ultrasonic Flowmeter

Page 53

7.5.2 Digital Pulse Output

7.6 Data Logging

The digital pulse output has a frequency range of 0 to 1000 Hz. The correspondence of pulse frequency to flow rate can be configured by specifying two (flow rate, frequency) points. Low and high flow rates, which must not be the same, are specified and the frequencies corresponding to each are given. Other flow rates are mapped to pulse frequencies using a straight line through the points specified. The frequency for the high flow rate may be smaller than the frequency for the low flow rate, in which case the frequency will decrease with increasing flow rate. Flow rates mapping to frequencies outside the available range will cause the signal to saturate at the closest limit.

The flowmeter is able to log flow data internally to a memory buffer and to a removable SD Card. If the Communication Board is fitted and connected to a PC running the flowmeter software application, the internal buffer data will automatically download to the user’s PC hard drive. The generation of a log entry can be triggered periodically, by the flow rate passing configurable setpoints and by the total flow passing configurable setpoints. All log entries are identical and do not indicate which of the forgoing mechanisms caused their generation. All log entries look like this:

2006/12/15 13:10:43 Rate: 2396.25 Total: 4345625.38 Code:

The date is ordered year/month/day. The time is military or European time, so no a.m./p.m. field is needed. The flow rate and total flow are recorded as they would appear on the display, u Up to two error codes will be recorded if present.

nits of measure are not included.

7.6.1 Periodic Logging

7.6.2 Logging Rate Setpoints

The internal memory buffer can hold approximately 10,000 log entries. The 32 Mbyte SD card (included) will accommodate about 500,000 entries. At one entry per minute, it will fill up in a little less than a year. If the SD Card is not present, data logging still takes place but only buffered entries can be retrieved by a User PC Software application, see section 7.6.5 below.

The interval between periodic log entries can be configured from 1 to 999999 seconds. If this number is set to zero, periodic logging will not occur. Log entries can only be generated when flow information is produced for display.

Maximum and Minimum Flow Rate Setpoints can be configured in Setup Mode so that the flowmeter records the time at which the flow rate crosses these values. A log entry is generated when the flow rate crosses the Maximum Flow Rate Setpoint value while increasing. A log entry is also generated when the flow rate crosses the Minimum Flow Rate Setpoint value while decreasing. These log entries are not distinguished from other entries and consist, as always, of the timestamp, the flow rate immediately after the setpoint was crossed and also the total flow at that time.

When a log entry has been generated due to the crossing of a Log Rate Setpoint, as described here, no further log entries are generated due to the crossing of the same Log Rate Setpoint for a period of one minute. The intent is to suppress “flicker”, i.e. many log entries due to the flow rate hovering around the setpoint and crossing it repeatedly.

7.6.3 Logging Totalizer Setpoints

Log Rate Setpoints must be specified in the units of measure configured for flow rate.

Five Flow Total Setpoint values can be configured in Setup Mode so that the flowmeter records the time at which the total flow crosses each of these values. When this occurs, a single log entry is generated. It is not distinguished from other entries and consists, as always, of the timestamp, flow rate and the actual total flow value that exceeded the setpoint. Flow Total Setpoint values do not have to be in ascending order. They must be specified in the units of measure configured for flow total.

7.6.4 Local Log Data Storage (SD Data Card Storage)

7.6.4.1 Inserting and Removing the Memory Card

Log entries will be written to the flowmeter’s Flash memory card if one is installed. The flowmeter supports Secure Digital (SD) and MultiMediaCard (MMC) flash memory cards of most common brands and capacities. If a correctly formatted card is not installed appropriately (see below), log entries will not be written but in all other respects the flowmeter will operate normally. The flowmeter is shipped with a 32MB card installed.

To insert or remove a memory card, it is necessary to open the wiring access door of the flowmeter. The card slot is on the bottom of the main PCB, and therefore hard to see, but its position is marked on the top silkscreen. To insert a card, hold it with the label side away from, slide the end with the gold contacts under the PCB into the slot and push gently until it clicks into place. To remove a card, push it inwards until it clicks again and then release the pressure. A spring will push it out slightly. From this position, slide the card fully out.

The first time a memory card is installed, the meter must be power cycled while the card is in place. After the initial installation, the memory card should only be inserted or removed when the flowmeter is in the Setup Mode or if the meter is powered off. Before inserting or removing the card, use any of the methods described in section 4 above to enter Setup Mode. Flow measurement will be disrupted. After inserting or removing the card, the flowmeter can be returned to Startup and then to Run Mode, see section 4.3 above for details. If a card is inserted when the flowmeter is not in Setup Mode or powered off, no harm will be done but log entries will not be written to it. To remedy this situation, enter and then leave Setup Mode. If the card is removed when the flowmeter is not in Setup Mode, data on the card may be corrupt. After retrieving undamaged log files, the card should be reformatted. Additionally, the flowmeter should be power-cycled.

7.6.4.2 Format of Data on the Memory Card

7.6.4.3 Rotation and Purging of Log Files

SD/MMC cards for use in the flowmeter should be formatted according to the FAT32 standard. Files can then be written to and read from the card by any computer that understands this file system (when fitted with the appropriate adapter) including PCs running Windows or Linux .

Log entries are stored in files with names of the format lognnnnn.txt, where nnnnn is a decimal number from 00000 to 99999. Each log entry is written to a separate line in the file and is terminated with the newline character. Some older Windows-based text editors may not recognize newline as a line break (without a carriage return following it), but most modern software is compatible with this format. Log files are placed in the sub directory logs of the root directory of the memory card. Any files on the memory card that are not in the logs sub-directory or do not have names in the above format will be ignored by the flowmeter. Although they will reduce the space available for log files, they will not be deleted. Any files in the logs sub-directory with names that do look like log file names are at risk of being deleted to free up space on the card.

The log file currently in use is closed and a new one is opened in these situations:

! The flowmeter enters Setup Mode and then subsequently passes to Run Mode ! The log file reaches a size of approximately 1 MB (about 16,000 entries)

The five-digit number in the names of log files progresses by one each time this happens, so it is trivial to reconstruct the sequence of log entries over different files. In this sequence, 00000 follows 99999.

Ultrasonic Flowmeter

If the memory card has less than 1 MB of free space when a new file is opened, the oldest log files are deleted until this much free space exists. Thus, if log files are not moved off of the card before it fills up, new entries are preserved at the expense of old entries.

Page 55

7.6.4.3 Rotation and Purging of Log Files (continued)

7.6.4.4 Power Loss

The five-digit numbers of the next log file and the oldest log file on the card are held in a file in the logs sub-directory with the name logindex.txt. If this file does not exist, the flowmeter will create it and start both numbers at 00001. Thus, the first log file will be log00001.txt and as further files (log00002.txt etc.) are created and filled the flowmeter will remember that log00001.txt is the oldest. If the space on the card is reduced below 1 MB, then log00001.txt will be deleted. The next file to be deleted to make space will be log00002.txt and so on.

When reading a card that has been removed from a flowmeter, care should be taken when deleting files before re-inserting it into the same or a different flowmeter. It is safe to delete all files on the card, in which case new log files will start with log00001.txt as described above. It is also safe to delete any or all log files if the file logindex.txt is left on the card. If the flowmeter tries to delete a file that does not exist, it will simply keep increasing the five-digit number in the filename until it finds enough files to delete that free up the space it is looking for. However, if the logindex.txt file is deleted

but log files are left on the card, the flowmeter may overwrite them if and when it counts up again to their numbers.

In the event of a power loss, the flowmeter will not be able to properly close the open log file and it may as a result be corrupt. When power is restored and the flowmeter resumes operation, it will open a new log file with the next sequential number. Should the power loss have occurred when the flowmeter was updating file system management information on the memory card, it may not be able to mount the card when power resumes. In this case, no further log entries will be written to the card. As a result, care should be taken that the flowmeter is placed in Setup Mode before disconnecting it from a power source.

7.6.5 Remote Access to Log Data

A user PC that is running the Software and that is connected via the Communications Board will automatically acquire and store log entries from the flowmeter.

The flowmeter records in a buffer the most recently generated 10,000 log entries. If the buffer fills, entries are replaced in a first-in, first-out manner. At ten second intervals, the PC will request that the flowmeter send to it the latest 100 available entries, also in a first-in, first-out manner, until all entries are downloaded. The entries sent are removed from the flowmeter buffer and transferred to a file folder that t Application will create and place on the C: drive. Since all meters must have a unique IP Address to connect to the user PC Software, the Software will automatically use the IP Address as the name of this file folder.

Simply by making this request every ten seconds, the PC obtains a complete record of the data being logged in the flowmeter. There is no configuration item to turn on or off remote logging or to set up what is logged differently from internal logging to the SD card. The flowmeter is passive other than buffering and supplying on request its recent log entries. The user PC can do whatever it sees fit with the log entries, including, but not limited to, displaying them graphically, saving them to disk, comparing them to information from other flowmeters, etc. Remote logging is not influenced by the presence

or absence of the SD Card.

To facilitate faster downloading, a button on the user PC software application may be pressed to immediately begin downloading all available logs in the buffer.

8.0 Process Control

Process Control functions are configured from the Setup Mode as described in section

5.4.4 above. In addition, you can interact with Process Control functions in Run Mode using Process Control Screens for each of the three relay channels. On these screens, you can inspect alarm status, clear alarms, dispense fluid batches, etc. Use of the Setup

Mode has been discussed above. This section covers the use of the Process Control Screens.

To access Process Control Screens from the Run Mode Screen, press the RELAY soft button. This button does not appear (the soft button label is blank) if the Process Control option is not fitted to the flowmeter. None of the functions discussed in this section are available without the Process Control option. Additionally, either the Model 3 display option or the Communications Board and a connected User PC Software Application are necessary to perform the operations described. You must have at least one of these if they have a Process Control Board, otherwise it will be useless.

8.1 Process Control Screen

In Run Mode, Process Control functions are accessible in from the Process Control Screens. Pressing the RELAY soft button moves in a circular fashion from relay to relay

and then back to the Run Mode Screen. Only those relay channels are visited that are configured to monitor Rate or Total in the active configuration. Relay channels that are disabled are skipped. If all relays are disabled, the RELAY soft button does not appear on the Run Mode Screen. This soft button is in the same location on the Run Mode

Screen and the Process Control Screens.

The Process Control Screen displays:

the selected relay number and whether the relay channel is monitoring Rate or

Total if monitoring Rate, the current Flow Rate as it would appear on the Run Mode

screen either the alarm trigger, release and delay time settings, if it is monitoring Flow

Rate or the batch settings, count and totals, if it is monitoring Flow Total

the state of the relay channel (described below)

For relay channels monitoring Flow Rate, a CLEAR soft button allows you to de-activate a relay that has been energized due to the rate reaching the trigger settings (see section

8.3.2 below for details).

For relay channels monitoring Flow Total, a START soft button allows you to start the dispensing of a batch (see section 8.2.1 below for details). Also for channels configured for Flow Total, and soft buttons allow you to select certain of the settings and status values. According to which is selected, a CLEAR or EDIT soft button appears.

Ultrasonic Flowmeter

Pressing the CLEAR soft button zeros the selected total. Pressing the EDIT soft button allows the Batch Amount to be changed. (See section 8.2 below for details and restrictions.) When the Process Control Screens are displayed, the flowmeter continues to operate normally in Run Mode. Flow is measured and totalized and all logging, monitoring and output signal functions continue uninterrupted. The SETUP soft button is not available. To leave Run Mode, first return to the Run Mode Screen using the RELAY soft button.

8.2 Batch Dispensing

When a process control relay channel is configured to monitor Flow Total, it can be used to dispense fluid in batches. A Process Control Screen for a channel configured in this way is shown at right. The RELAY soft button is used to visit each channel in turn and go back to the Run Mode screen. The START soft button is used to initiate a batch. The left-most three soft button may be used to change the Batch Amount or clear the batch counter and the volume totals.

Manual Batch Start

Start Type

If the Batch Start type is configured as MANUAL, then operation is as follows:

! Press the START soft button to begin the dispensing of a batch. ! The START soft button is replaced by the STOP soft button. ! The Total this Batch: value clears to zero. ! The Current Batch #: value increases by one. ! The relay is energized and the display changes accordingly. ! As the flowmeter measures and totals up fluid flow, the Total this Batch: and Total

all Batches: values advance.

! When the Total this Batch: value reaches the Batch Amount: value, the relay is de-

energized and the display changes accordingly.

! The STOP soft button disappears and the START soft button returns.

A batch can be interrupted and resumed as follows:

! Press the STOP soft button. The relay

is de-energized and the RESUM (resume) soft button appears in place of this soft button.

! Although the display changes to show

that the relay is de-energized, it alternates between black-on white and white-on-black to indicate that a batch has been interrupted.

! The flowmeter is still measuring flow,

although the intent is clearly for the flow to stop, and the operation of all status displays continues.

! Press the RESUM soft button. The

relay is energized again, the STOP soft button reappears and everything is as it was before the interruption.

Ultrasonic Flowmeter

Page 58

A batch can be canceled (aborted) as follows:

! Interrupt the batch as described above. ! While the batch is stopped (the relay is de-energized), use the or

soft buttons to navigate to and highlight the Total this Batch: status line. The CLEAR soft button replaces the RESUM soft button.

! Press the CLEAR soft button. ! The value of Total this Batch: is cleared to zero. ! All lines are de-selected and the START soft button returns. ! When the START soft button is next pressed, will dispense and the

Current Batch #: value increases by one. The cancelled batch is not re-dispensed. The flow measured before it was cancelled is not backed out of Total all Batches:.

Because flow information is only computed by the flowmeter at the configured display update interval, the volume dispensed in a batch will typically overshoot the configured Batch Amount. The relay is de-energized when the measured total equals or exceeds the batch volume. The degree of overshoot depends on the batch size, the flow rate and the update interval. You should not configure long update intervals when dispensing small batches from a high flow rate, as in this situation the overshoot could be a significant fraction of the batch size.

the next batch

8.2.2 Auto Batch Start Type

If the Batch Start type is configured as AUTO, then operation is as follows:

Immediately upon entering Run Mode, the flowmeter accumulates the volume of fluid flowing in two totalizers associated with the specific Relay Channel. If the relay channel is brought onto the display (using the RELAY soft button), the totals are displayed to the right of the labels Total this Batch: and Total all Batches: and the values will be seen to advance. However, the channel will operate in the manner described

here whether it is on the display or not.

! The relay channel Status: is indicated

as ACTIVE.

! When the Total this Batch: value

reaches the Batch Amount: value, the Current Batch #: value increases by one, the Total this Batch: value clears to zero and the relay is energized. Flow is expected to continue (in this mode, flow is not controlled by the relay), so Total this Batch: immediately starts increasing again and Total all Batches: continues to increase without a break.

! After the relay has been energized for

the number of seconds shown in the Relay Timer: field, it de-energizes (again, this is not expected to influence

the fluid flow).

Ultrasonic Flowmeter

This continues indefinitely (unless the STOP soft button is pressed). Each time the Total this Batch: totalizer reaches Batch Amount:, it is cleared, Current Batch #: advances and

the relay is energized for the time Relay Timer:.

In this mode of Process Control, the flowmeter is partitioning the flow in the pipe into batches of a defined amount. Within each batch, it displays the total flow so far for that batch. It counts the batches. At the end of each batch, the relay energizes for a defined time period and then de-energizes. An example of what the energized relay might do is to switch power to a pump or open a valve that results in some other fluid being injected into the measured fluid stream.

Page 59

Ensure that the flow rate, batch amount and relay timer are set up so that the relay will de-energize before the end of each batch. Should the relay still be energized when the end of a batch is detected, then the time at which the relay will de-energize will be extended to the Relay Timer time from the new batch ending. If this repeats, the relay could remain continuously energized.

If the STOP soft button is pressed:

! The relay channel Status: is indicated

as PAUSED.

! If the relay is energized, it will

immediately de-energize.

! The RESUM (resume) soft button

appears, replacing the STOP soft button.

! The flowmeter will no longer advance

Total this Batch: nor energize the relay and increment Current Batch #: as batches of fluid pass by in the pipe.

! Total all Batches: continues to advance

if there is flow in the pipe.

If the RESUM soft button is pressed:

8.2.3 Batch Clear

8.2.4 Batch Edit

! The relay channel Status: returns to ACTIVE. ! The RESUM soft button is replaced by the STOP soft button. ! The Total this Batch: value clears to zero. ! The Current Batch #: value increases by one, indicating a new batch in progress. ! Operation is as before STOP was pressed (Total this Batch: advances and, at the

end of each batch, clears, energizing the relay for a specified time and advancing Current Batch #:).

To start counting batches from zero again or clear the value of Total all Batches:, use the

and and CLEAR soft buttons.

The Current Batch #, Total this Batch and Total all Batches values can be cleared. To do this, press the and soft buttons until the desired value is highlighted. The CLEAR soft button then appears in the left-most position. Pressing this soft button zeros the value.

The clearing of counts and totals can be blocked by configuring the Total Display Function to Clear Total Disabled. If this is done, the CLEAR soft button does not appear. Note that this configuration item is in the Metering Setup branch, but even so affects Process Control functions.

If the relay channel is configured for Batch Start type MANUAL, the Batch Amount: value can be changed. To do this, press the and soft buttons until the present value is highlighted. The EDIT soft button then appears in the left-most position. Pressing this soft button allows the value to be edited.

It is not possible to change the Batch Start: type or the Relay Timer: value. It is also not possible to change the Batch Amount: value if the Batch Start type is AUTO.

8.3 Flow Rate Alarms

8.3.1 Basic operation

When a process control relay channel is configured to monitor Flow Rate, it can be used to indicate that the rate of fluid flow has reached or passed configured trigger values. A Process Control Screen for a channel configured in this way is shown at right. The RELAY soft button is used to visit each relay channel in turn and go back to the Run Mode screen. The CLEAR soft button can be used to clear an alarm condition while the problem causing the alarm is being rectified.

Operation of Flow Rate Alarms will be described with reference to the state diagram below.

The relay channel starts in the CLEAR state. It will remain in this state so long as the displayed flow rate remains both less than the High Trigger value and greater than the Low Trigger value. Note that the displayed flow rate is subject to the configured averaging, high and low flow cutoff and any scaling offset value.

If the flow rate rises to or above the High

Trigger value or falls to or below the Low Trigger value, then the relay channel

changes to the ALARMING state (arrow a in the diagram at right). If the Alarm Delay Time has not been configured or it has been configured to zero, the relay channel immediately changes to the ALARMED state (arrow b). Otherwise, it remains in the ALARMING state while the Alarm Delay Time is counted down. In this state, the relay is not energized. The status displays as Status: ALARMING in alternating black-on white and white-on-black and the CLEAR soft button is present. If the CLEAR soft button is pressed, counting down the Alarm Delay Time restarts. This state gives an operator time to correct the condition causing the alarm or for the condition to correct itself if it is transient.

Ultrasonic Flowmeter

When the Alarm Delay Time expires in the ALARMING state (which may be immediate, see above) the relay channel changes to the ALARMED state (arrow b). The relay is energized. The status displays as Status: ALARMED in white-on-black. The CLEAR soft button is present. If the CLEAR soft button is pressed in the ALARMED state and a non-zero Alarm Delay Time is configured, the relay channel changes to the

CLEARING state (arrow c). The relay is now de-energized. The status displays as Status: CLEARING in white-on-black and the CLEAR soft button is not present. The

purpose of this state is similar to the ALARMING state, but it is available after the alarm has occurred if the operator did not act early enough. The flowmeter counts down the Alarm Delay Time. If this time expires and the condition causing the alarm has not been removed (arrow e, see below), the relay channel returns to the ALARMED state (arrow d). If the CLEAR soft button is pressed in the ALARMED state but Alarm

Delay Time is zero or has not been configured, then nothing will happen unless a Release value has not been configured and the flow rate has returned to normal (more

on this below). In this case, the relay channel changes to the CLEAR state (arrow e).

In the ALARMING, ALARMED and CLEARING states, the relay channel may change to the CLEAR state (arrow e) without user action if a Release value has been configured for the Trigger value that has been passed to cause the alarm and the flow changes to be equal to or inside that release value. For example, if the alarm occurred because the flow rose above the High Trigger value and a High Release value has

Page 61

been configured, then at any time the flow falls to or below that value the alarm is automatically cleared and the relay channel returns to the CLEAR state. (This is what the operator is going to be striving for in the ALARMING and CLEARING states.) If a Release value has not been configured for the Trigger value that caused the alarm, then the relay channel will only follow arrow e back to the CLEAR state if the flow falls back inside the Trigger value and the operator presses the CLEAR soft button (as first stated above). A Release value that is identical to its corresponding Trigger value has the same effect as if it were not configured (it prevents automatic recovery from that direction).

The Alarm Delay Time cannot be configured to a value greater than 3600 (one hour). If the Alarm Delay Time is configured to zero, it is effectively disabled and displays as

NONE.

Any Trigger or Release value that is set to zero is effectively disabled and displays as NONE. This includes the Low Trigger, so if the user wishes to alarm on zero flow, he

must set the Low Trigger to a very small, but non-zero, flow value. Disabling a Trigger value causes the corresponding release value to be also disabled. If a Release value is disabled, or set to the same value as the corresponding Trigger, then the flowmeter will not automatically release an alarm caused by that trigger (the CLEAR soft button must be pressed to release the alarm).

8.3.2 Clearing Alarms

The CLEAR soft button appears on the screen in the ALARMING state and also in the ALARMED state if an Alarm Delay Time has been set or if no Release value has been

set for the Trigger that caused the alarm.

If the CLEAR soft button in the ALARMING state, the countdown of the Alarm Delay Time will re-start, providing extra time to correct the problem.

If the CLEAR soft button is pressed when in the

Delay Time has been set, then the relay will de-activate, the Status: display will read CLEARING in white-on-black and the CLEAR soft button will disappear. The intent is

that the operator now goes and fixes whatever caused the flow to go out of bounds. If the flow falls within the Release limits before the alarm delay time expires, then the Status: display will read CLEAR and the relay will remain de-activated. If the number of seconds set in the Alarm Delay Time: pressed and the flow rate is still outside of the Release limits, then the relay reactivates, the Status: display will read ALARMED and everything will be as it was before the soft button was pressed.

If the CLEAR soft button is pressed when in the Delay Time has been set and no Release value has been set for the Trigger that caused the alarm, then what happens depends on whether the flow has fallen back inside the Trigger value. If it has, the alarm will be cleared. If it hasn’t then nothing will happen.

Page 62

8.3.4 More on Alarm Conditions

This section contains additional explanation of the conditions under which an alarm condition is cleared.

The flowmeter will clear an alarm condition automatically if and only if a Release value has been set for the Trigger value that caused the alarm. For example, if the alarm was caused by the flow rate falling below the Low Trigger, then the alarm will be automatically cleared if a Low Release has been set. Whether or not a High Release is set in this case is of no consequence. If a Release value has not been set, the alarm is said to be “latched”. A latched alarm can only be cleared if the user presses the CLEAR soft button and the flow rate has fallen back inside the Trigger values.

The effect of setting an Alarm Delay Time is to add states in which an alarm condition exists but the relay is temporarily not energized. During these states, the alarm condition may clear and the relay will then remain de-energized. These states end when the Alarm Delay Time elapses and if at that time the alarm condition has not cleared then the relay will energize.

The four combinations of a set Release value (for the alarming Trigger value) and an Alarm Delay Time are as follows:

?No Release value, no Alarm Delay Time - the alarm is latched and can only be

cleared by the user pressing the CLEAR soft button when the flow rate has fallen inside the Trigger value.

! Release value, but no Alarm Delay Time - alarm clears automatically as soon as

the flow rate falls inside the Trigger value (the CLEAR soft button serves no purpose).

! No Release value, an Alarm Delay Time is set - the alarm is latched (will never

clear automatically) and must be cleared by the user pressing the CLEAR soft button, however, as well as clearing on the press if the flow is inside the Trigger value, it will also clear if the flow falls inside the Trigger value while the Alarm Delay Time is being counted down (the channel is in the CLEARING state).

! Release value and an Alarm Delay Time - the alarm clears whenever the flow

rate falls inside the Trigger value and the purpose of the CLEAR soft button is only to temporarily de-energize the relay.

9.0 User PC Software

This section describes the Sonic-Pro User PC Software application.

Any flowmeter model can be equipped with a Communications Package that includes circuitry, connector panel and custom User PC Software. When connected to a computer running the software, any model can perform the Model 3 functions described in this

manual including program editing and data logging downloads directly into the PC.

The Software user interface mimics the 5button touch pad so learning to use the software application is simple. Simply clicking on the buttons is the same as pressing the buttons on the SPU touch pad. Pressing and holding shift while clicking on a button simulates pressing and holding a button on the touch pad.

9.1 Software Installation

9.2 Making connections

9.2.1 Ethernet Connection

The Software installation files are located on the CD that was shipped in the flowmeter. Open the CD and double click SETUP. Follow the instructions to install the Sonic-Pro software onto your PC.

When opening the software, a connection type must be selected. Chose ETHERNET, RS-232 or USB.

If connecting via ETHERNET, select a meter from the pull-down menu and press DONE to activate the selected meter. If the display does not activate of if some of the data is not displayed, disconnect the meter by clicking on OPERATION in the upper left corner pull down menu and click DISCONNECT. Re-select the meter and press DONE.

To ADD a new meter to the pull-down menu, press ADD, input a name for the new

meter, input the meter IP ADDRESS and IP PORT number (usually 26000). Press SAVE EDITS. The IP ADDRESS must match the IP address configured in the meter SPU. See section 5.2.1 of this manual. If the meter is installed on a network, the IP address must be an address that is available to the network. Contact your IT department for assistance with network configurations. The new meter can now be selected and activated.

An unlimited number of meters may be added to the pull-down menu but only one meter at a time may be selected.

Ultrasonic Flowmeter

9.2.2 Serial & USB Connection

9.3 Retrieving Log Data

If connecting via RS-232, you must select a SERIAL COM PORT number.

If connecting via USB, you must select also select a COM PORT number. This is because the USB connection utilizes a USB/SERIAL conversion method.

First connect the USB cable to the SPU. Once connected, the new COM PORT number should automatically appear in the pull-down menu and can now be selected. (It

will most likely be the largest number port shown.)

NOTE: On some computers, an adjustment will be need to be made to the “latency timer” setting on the USB COM port to enable proper communications. Go to Control Panel /

Systems and maintenance / Device Manager. Select PORTS. Double click USB CONVERTER. Select the PORT SETTINGS tab. Click ADVANCED. Set LATENCY TIMER to a value of 1. Save the settings.

When the software is connected to the SPU and activated, ALL log data that is stored in the SPU buffer is automatically downloaded to a folder and placed

on the computer’s C: drive. Log data is stored in a .TXT file.

named “Ultrasonic Flowmeter”

The SPU can store approximately 10,000 logs. New logs will replace old logs on a first in first out protocol.

Each individual log file consists of Date, Time, Flow Rate value, and Flow Total value.

2008/07/15 07:18:27 Rate: 3.241483 Total: 147.137275 Code:
