Overview

FLUXUS ADM 6725 is a flowmeter that uses ultrasound to measure the flow in closed

pipes or conduits. FLUXUS can measure volume flow, flow velocity or mass flow of liquids within a

temperature range f r om -30 °C up to 130 °C. Wit h specially designed high temperature transducers, the temperature r ange can be extended up to 250 °C, and for short periods up to 300 °C.

FLUXUS works with all commonly used pipe materials such as steel, synthetic material, glass or copper. Pipe diameters may range from 6 up to 6,500 millimetres (depending on transducer type).

FLUXUS utilises two transducers, which are mounted onto the outside of t he pipe (clampon principle). This means that measurem ent s ar e always made non-invasively, without affecting the pipework or t he liquid to be measured. The transducers ar e sm all, lightweight and also very robust.

FLUXUS is a portable, battery operated measuring inst rument suitable for field use. Flow measurements can easily be undertaken at different locations on the pipe system. The unit can also be operated with an external power supply of 9 to 15 V DC. The mains power adapter and battery charging unit, supplied with the standard inst r um ent, can be used as an external power source. FLUXUS features a protect ion degree of IP54 and is, therefore, suitable f or monitoring tasks under difficult environmental conditions. With an optional waterproof and dust tight carr ying case, the ingress protection can be increased to IP 68 for the complete measuring system.

FLUXUS may also be used in specific applications. Our specialist personnel can advise you in finding the most appropriate solution for your measurement problem.

FLUXUS allows the operator dialogue in differ ent languages and guides the user throug h the menus for parameter set - up and m easur em ent. With the keyboard, you can enter data or can select relevant measurement parameters from the choices FLUXUS offers. The backlit display shows your input data and the results of measur em ent s as well as operational errors.

FLUXUS has a serial interface. This allows to transfer the data measured by FLUXUS to a Personal Computer (PC), or to out put t hem as numerical values or graphics via an external printer. The data transferred to a PC can be processed by EXCEL, LOTUS or any other data analysing program.

FLUXUS opens up new avenues for the safe measurement of aggressive or high temperature media flowing in closed conduits.

FLUXUS can be fitted with various process interfaces as required by the cust om er . The FLUXUS ADM 6725 features an integral measuring point multiplexer for two

channels that allows for the connection of up to t wo independent tr ansducer set s with one portable flowmeter. Several calculation funct ions can be per formed with the two flow channels.

Functional Description

1 Functional Description

1.1 Measuring Principle

FLUXUS utilises ultrasound for the measurement of liquid flow, employing the so-called transit time method. The instrument measures the drift of ultrasonic signals resulting from their travel through the flowing liquid. The ultrasonic signals are transmitted alternatively with the direction of flow and against it.

The flowing medium causes diff erent transit times of these t wo sound signals. From the time difference, FLUXUS identifies the average flow velocity along the path of acoustic propagation. Through a flow profile correction, FLUXUS calculates the average flow velocity with reference to the cross sectional area, which is proportional to the volume flow.

This effect can be observed over the complete range of flow velocities found in technical applications. This allows FLUXUS to cover a wide flow measuring range and also to determine the direction of flow within the pipe.

Ultrasonic waves also propagate solid materials. Thus, the transducers (alternatively operating as sound transmitters and receivers) can be mounted onto the outside of pipewalls. FLUXUS makes use of that possibility, so t hat the installation is very easy and can even be performed while the process is in operation. In order to avoid wrong measurements, FLUXUS, with its special electronics, test s the incoming ultrasonic signals for their usef ulness for the measurement and evaluates t he plausibility of the measured values.

The microprocessor integrated in FLUXUS controls the complete measuring cycle, eliminating disturbance signals by statistical sig nal processing techniques.

Flow disturbance sources within the pipe system, e.g. slide valves, elbows, pumps or other flow elements, distort the flow profile and, therefore, m ay influence the measuring result. Thus, certain minimum distances from the selected measuring point to the disturbance source should be observed.

FLUXUS has in-built facilities to help the user to select the correct t ransducer position on the pipe.

1.2 Operating Conditions for FLUXUS

FLUXUS, in comparison with other well-known principles of flow measurement, offers a range of advantag es. These st em f rom the ultr asonic measuring principle, employing t he transit time method in conjunction with clamp-on transducers.

FLUXUS can always be used where the pipewall and the liquid to be measured are sonically conductive. This is true for pipewalls consisting of homogeneous material, and for liquids, which carry only a certain amount of solid particles or gas bubbles. There is

Functional Description

no dependency on electrical parameters of the fluid such as conductivity or dielectric constant.

With FLUXUS, flow values can be determined immediately, in a non-invasive manner from the outside of pipes, and without inter ruption of the process. Mounting of the transducers is straightforward, so that flow measurements can be made at various locations in the plant and on pipes with different diameters. The installation does not require any alterations to the pipe system, and it does not inf luence the cross-sectional area of the pipe nor the actual flow conditions.

Using FLUXUS, one of the bigg est advantages in comparison with other flow measuring techniques (orifice plates, variable area meters, electromagnetic flowmeters, vortex flowmeters, and others) is when measurements have to be undertaken at various locations at different times, e.g. the maintenance of a pipe system, plant start-up, commissioning of process equipment , or oper ational production checks.

Often, FLUXUS is the only acceptable solution f or the flow measurement on pipes with very large diameters or in situations where, for technical and economical reasons, the use of other flowmeter systems is restricted. This is especially true if the process facility cannot be shut-down for the installation of a flowmeter.

For permanent installations, there are particular advantages where aggressive media (acids, bases, poisonous fluids) would considerably diminish the lifetime of insertion devices or prohibit the use of any type of insertion flowmeter at all.

FLUXUS displays error messages if specific operating conditions are present which prevent measurement. Such conditions might include t he following:

••••

Heavy internal deposits on the inner pipewall

The ultrasound will be too heavily attenuated by these deposits. However, the sensitivity of the FLUXUS electronics is current ly the best available on the m ar ket. FLUXUS will still provide correct measuring results where other clamp-on ultrasonic flowmeters would fail.

••••

Disturbing particles (solid parti cl es, gas bubbles)

Particles scatter and absorb the ultrasound in t he liquid and, therefore, attenuate the signal. If the proportion of solid particles or gas bubbles increases to more than 10 %, measurements might not be possible any more with the transit-time mode. However, the unit can still give meaningf ul results using a secondary measurement mode called NoiseTrek, a measuring mode which actually relies on part icles and/or gas bubbles in the liquid.

••••

Inner-lined pipes

Lined pipes may cause measurement dif ficulties if the lining is not bonded correctly to the pipewall, or consists of a material which has bad acoustic characteristics.

••••

Gases

Gases prevent flow measurements with clamp-on transducers in principle.

••••

Porous pipe materials, e.g. concrete

For such materials, measurements are only possible in certain condit ions, and ar e sometimes impossible.

••••

Liquids with viscosity values of more than 1000 mm2/s

These liquids would restrict the application of FLUXUS. High viscosity values

Unpacking

The transport case is divided into several compartments for the basic instrument and its accessories.

Only unpack the transport case, when it lies flat on its large bottom surface. This will ensure that the unit and accessories cannot fall out.

Make sure that the little red cover f or the serial interface at the rear of the unit will not be lost.

Storage

Always pack the instrument and its accessories into their respective compartments of the transport case after measurements have been performed.

Wipe the transducers clean of traces of acoustic coupling component. Tilt the instrument handle towards the upper front face of FLUXUS and not onto

the topside of the housing. This avoids scratches on the enclosure, caused by the instrument handle, during transport. Avoid excessive cable bends especially when closing the transport case top cover.

2.5.3 Status

SIGNAL

OFF The flowmeter works off-line. LED green on The received signal is sufficient for measurements. LED red on The received signal is insufficient for measurements.

2.6 Power Supply

The chargeable NiCd-batteries guarantee an operating time (continuous measurements at normal measuring rate) of approximately 15 hours.

If required, the flowmeter can operate from an external power supply of 9 to 15 V DC. The mains power adapter and battery charging unit can be used for this purpose.

During battery charging, the battery set must remain in the battery compartment of the instrument. Connect the mains power adapter and battery charging unit and make sure that its plug snaps in correctly. Select the menu function "Charge Battery" within the program branch "SF - Special Function".

2.6.1 Switch-off Automatic

FLUXUS will activate an automatic switch-off whilst the flowmeter waits for an input and there has been no keyboard action for a period of 15 minutes. Before the switch-off automatic operates, a tone signal will sound and the following indication will appear on the display counting down in second intervals:

LOW BATTERY

WHILE POWER OFF

If this error message appears after FLUXUS has been switched ON, it indicates that the unit has switched itself off because of low batteries.

Note:

If the device works from an external power supply, the switch-off automatic does not operate.

2.6.2 Battery Handling

The battery life expectancy depends on the handling of the batteries and certain precautions being taken.

For longer periods of storage, batteries should be kept at low temperatures (0 °C to 10 °C). Storage in cool conditions will lower the self-discharging by a factor of 1/10.

Note:

Store the battery set only in its charged condition. Avoid the so-called Memory Effect, i.e. to charge the batteries in ever shorter times

with a low charging capacity, by discharging the batteries in a smooth and continuous manner before a new charging cycle is being started.

Do not deep-discharge batteries.

Selection of the Measuring Point

3 Selection of the Measuring Point

The correct selection of the measuring point is crucial to success in achieving reliable measurements and a high accuracy. Preconditions for obtaining good measuring results are:

• A pipe that can be acoustically propagated.

• A fully developed axi-symmetrical flow profile.

3.1 Acoustic Propagation

Acoustic propagation can be assumed when pipe and medium do not attenuate the sound so that the signals get completely absorbed. Sound attenuation depends on:

• the kinematic viscosity of the liquid,

• the proportion of gas bubbles and solid particles in the liquid,

• deposits on the inner pipewall,

• the wall material.

When a measuring point selection is being made, make sure that,

• the pipe is always filled completely where

the sensors are positioned,

• no bubbles and deposit material accumu-

late in the pipe at the measuring point.

(Also bubble-free liquids can form gas pockets where the liquid expands, e.g. especially behind pumps and where the crosssectional area of the pipe extends considerably.)

3.2 Undisturbed Flow Profile

Many flow elements cause disturbances of the flow profile in the pipe, e.g. elbows, slide valves, valves, pumps, T-sections, reducers and diffusers. Through these disturbance sources, the flow profile is distorted to something other than an axisymmetrical shape.

Therefore, keep sufficient distance between measuring point and any such disturbance sources.

Only then can we assume that the flow profile in the pipe is fully developed. However, FLUXUS will give you meaningful measuring results even under nonideal measuring conditions, i.e. with a liquid containing a certain proportion of gas bubbles and/or solid particles, and if the recommended distances to flow disturbance sources can not be observed to the book for practical reasons.

With careful selection of the measuring point, you should reduce the impact of disturbances sources.

FLUXUS uses the sound velocity of the medium for the calculation of the transducer distance at the beginning of the measurement. However, the sound velocity does not influence the measuring result directly.

The correct positioning of the transducers is very important and is a pre-condition for error-free measurements. It guarantees that the sound signal will be received under optimum conditions and evaluated correctly. Because of the variety of applications and factors influencing measurement, there can be no standar d solution for the positioning of the transducers. The correct posit ion of the transducers will be influenced by

A:Sound Path

(Letter A = Channel A)

By entering an even number under Sound Path, the reflection transducer mounting method can be chosen.

Transducer 1 Transducer 2

In reflection mode, the transducers must be mounted on the same side of the pipe wall. The sound waves are reflected by the opposite pipewall. Thus, the length of the sound path in the pipe doubles. The accuracy of the measurement increases.

5 - 6

ADM 6725 E10



KAT

Program Branch MEASURING

However, the increased transit distance f or the sound also leads to a higher attenuation of the signal in the flowing medium. Furthermore, the reflection on the opposite pipewall causes additional amplitude losses of the sound signal.

Note:

It is always advisable to select the reflection mode if the pipe is sufficiently sonically conductive and the pipewall is relatively smooth. However, FLUXUS will respect your decision. Generally, the correct positioning of the transducer in reflection mode is easier than using the diagonal method.

5.2.4 Transducer Installation in Diagonal Mode

If you experience higher sound attenuation and if t here ar e deposits on t he inner pipewall, the transducer should be mounted using the diag onal method. In this inst ance, the sound signal only travels through the pipe once. But under non-ideal conditions in the pipe, the amplitude of the received signal is considerably higher than if t he reflection method had been applied.

In diagonal mode, the second transducer must be mounted on the opposite side of the pipewall.

M6 A bar graph g ives an indication of the quality

of the received signal. Adjust the transducers so that a maximum is

being indicated on the bar gr aph display by moving or turning the transducers slightly:

Attention!

Moving/turning of the transducers will show the local signal maximum on the bar graph display. It is important for the flow measurement that the signal maximum is used with the shortest transducer distance (shortest transit time). However, the signal maximum with the shortest transducer distance should not deviate from the suggested distance by more than ± 0.5 cm. Bigger deviations would mean that parameter inputs should be checked for correctness or that the measurement must be repeated at a different location of the pipework.

Renew the film of acoustic coupling component if necessary.

In practise, the ultrasonic beam does not always go straight through the pipe. This depends on the symmetry of the pipe, the deposits on the inner pipewall, and the reflection of the signals on the opposite inner pipewall. Under such circumstances, the signal maximum could be achieved slightly moving the transducers or turning them sidewards. Larger pipe diameters are especially affected.

Note:

If further measuring channels have been activated, e.g. measuring channel B, FLUXUS would begin the procedure to position the transducers for this particular channel. (Follow the sequence of this chapter 5.2.8 again accordingly.)

For special applications, the knowledge of the uncorrected flow velocity might be of interest. In pr ogram branch SPECIAL FUNCTIONS, you may enable or disable t he flow profile correction for the flow velocity

(see chapter 7.7.4)

Additionally by using HotCode definition, the flow profile correction for the flow velocity can be enabled or disabled and made cold-start resistant.

After entering the HotCode, this display appears.

The profile correction mode can be chang ed:

>NORMAL< means that the flow velocity is always a profile corrected value. >UNCORR.< provides flow velocities for output

and data storage without flow profile correct ion. Confirm your selection by ENTER. The MAIN MENU will appear again.

Note:

The set operational mode will be kept active even if a power failure or a cold start (INIT) occurred.

Further explanations

•

In program branch OUTPUT OPTIONS only 'Flow Velocity' will be available for

selection in any case. W hether the corrected or the uncorrected f low velocity will be provided depends on the set-up being performed by the above procedure at the beginning of the measurem ent .

•

Only if 'Flow Velocity' has been selected as the measuring quantity and the

operational mode was set to >UNCORR.<, will the uncorrected flow velocity be output or stored.

The calculation of the other m easuring quantities (volume flow, mass flow and heat flow) is

always performed with the profile correc t ed flow velocity completely independent of the set operational mode.

•

During measurement, the operat ional mode which is currently set can be identif ied by

the use of capital letters for the designation of the m easuring quantity:

2.60 m/s

FLOW VELOCITY

If ´FLOW VELOCITY´ appears in capital letters, the measuring value in the lower display is without profile correction. FLUXUS operates in >UNCORR.< mode.

2.47 m/s

Flow Velocity

If ´Flow Velocity´ does not completely appear in capital letters, the measuring value in the lower display line is the profile corrected flow velocity.

•

Uncorr ected f low velocities, which are stored in the memor y of the dat a logger , will be

marked 'UNCORR' near the unit of measurement and the generated ASCII files will be marked as follows:

In the ASCII file with the stored measuring values, ´???´ characters will be printed for invalid mean values and the associated quantity of measurement, whilst ´?UNDEF´ will appear for invalid temperatures. T here will not be an indication of how many momentary measuring values a valid mean value consists of.

5.4.3 Total Quantity Storage

FLUXUS can either stor e one value for the currently displayed total quantity counter or values for both flow directions. In prog ram branch SPECIAL FUNCTIONS, you may setup or change the Total Quantity Stor age mode

(see chapter 7.7.6)

Additionally by using HotCode definition, the Total Quantity Storage can be set-up or changed and made cold-start resistant.

(See also chapter 2.4.4)

Immediately after pushing the BRK key, enter

this key sequence from the MAIN MENU.

>ONE< both

Quantity Sto rage

The display will request the selection for the

storage mode of the tot al count er s:

>ONE< means, FLUXUS will only store the displayed total value. >BOTH< will enable storage of both total quantity counts.

Confirm by pressing ENTER.

The MAIN MENU will appear

again.

Note:

The set storage mode for the totalisers will remain active even after a power failure or a cold start (INIT) has occurred.

Further explanations

•

FLUXUS stores total quantity counts when, during measurement, the totalisers are activated

and when, in program branch OUTPUT OPTIONS, the function for data logging is enabled.

•

Should FLUXUS work in >AVERAG E< mode and heat flow has been selected as the

measuring quantity, the mode >BOTH< will remain ineffective. Then, FLUXUS will only store the

displayed total count.

•

The storag e of every totaliser value reduces the t otal number of measuring values which

can be internally logged by 2, i.e. the storage of both total quantity counts reduces the total number of measuring values which can be saved in the internal memory by 4 measuring values.

Example: In program branch SPECIAL FUNCTIONS FLUXUS shows that 10,000 measuring values can s till be stored. If the totalisers are activ ated and only one total value is logged, 3,333 data fields are available for storage. If both total values are saved, 2,000 data s torage operations can be made.

6.6 Output of Measured Values via Serial Interface

no >YES<

Serial Outpu t

O10 The output of measured values may also be re-

alised ONLINE via serial interface. The Storage Interval must be set when YES was selected.

(See

chapter 6.7)

FLUXUS transfers the measured data via serial interface with the same protocol structure as described for the storage of measured data in internal data logger. (See chapter 6.5)

To ensure easy import by PC programs (e.g. EXCEL), the for m at of the data transmitted via the serial interface (Online and Of fline) has the following structure:

• The measured data will always be output in table form. This means, that all measur ed values of different quantities belonging to a sample interval will be output in one line. For each quantity of measurement a colum n exists ( e.g. flow value, forward total, temperature T1). The columns are separated by a semicolon (;) or a tabulator character (ASCII #9).

• Each data set being transmitted contains at the beginning of the text a line with the respective quantities of measurement st ar ting with the characters ‘\*’.

Set-up of the format for the serial output

The format of the serial output can be adjusted depending on whether the data are being sent to a PC or transmitted to a serial pr int er . In program branch SPECIAL FUNCTI O NS, you may adjust the settings of the serial output

(see chapter 7.7.7)

Additionally by using HotCode definition, you can adjust the f o r m at and make it cold-start resistant.

Other available temperature inputs or process inputs

Columns with ONLINE serial out put ( during measurement)

In ONLINE mode, columns will be generated for all quantities which may be output during measurement.

(The columns Q_POS and Q_NEG c an remain empty, in case the totaliser function has not been

activated.)

Since for the measuring q uantity ‘flow velocity’ no total counting can be enabled,

no columns for total values will be generated.

Columns with OFFLINE seri al out put ( st ored measured values)

In OFFLINE mode, columns will only be generated if at least one measured value was stored in the respective data set.

(The columns Q_POS and Q_NEG are not generated if the totaliser function was not enabled.)

6.7 Set-up of the Storage Interval

A storage interval or rate must be set for:

•

the internal data logger of the instrument,

•

serial output ONLINE,

The set storage rate will be active for t he above-m ent ioned opt ions.

Note:

•

If none of these options are activated, FLUXUS will omit the display group

'Storage Rate'.

•

In multi-channel measurement mode, the storage interval can be set for each

channel independently. The storage interval in seconds for any measuring channel should be at least equal to the number of activated measuring channels.

(When 2 measuring channels are activated, the storage rate for a channel should be at least 2 seconds, not less.)

This is the display for setting the st orage interval:

7.2 Wo rking with Parameter Records

Parameter records are data that contain all necessary information to perform a certain measurement task. These data are:

• Pipe parameters • (Transducer parameters)

• Medium parameters • Output options

Parameter records can be created before each measurement and then be stored via SPECIAL FUNCTIONS. FLUXUS can store up to 14 different parameter records. If you wish to work with a stored parameter record, you need to select that record as "Current Record". This way, repeat measurement tasks can be performed with previously entered parameters much more easily and quickly.

7.2.1 Save Current Parameter Record

The parameters need to be entered first as previously described in chapters "Program Branch PARAMETER" and "Program Branch OUTPUT OPTIONS". If this has been done, the parameters can be stored as the current parameter record.

7.5 Selection of the Measuring Rate

Here, you need to decide, through selection of the measuring rate, upon the power consumption of the instrument.

• If you select the measuring rate MAX, measurements are carried out

continuously.

• If you select the measuring rate NORMAL, the measuring rate is equivalent to

about 20 % of the maximum rate. This means, that in this mode the power consumption of the instrument is 80 % less than with the device set for the maximum measuring rate. This set-up would be an essential aspect when FLUXUS is operated in battery mode and needs to measure over long periods.

Measuring Data Transfer to PC

8 Measuring Data Transfer to Personal

Computer

By connecting FLUXUS to an IBM-compatible PC, measuring data can be transferred from FLUXUS to a PC. The data transfer may either take place ONLINE (during measurement) or OFFLINE (after on-line measurements have been perfor m ed) .

The 3.5 " disk, which is part of the standard supply for the instrument, contains the current version of the utility programs MOVEFAST.EXE, MOVEDATA.EXE and FLXtoTXT.EXE for the data transf er to a PC.

• Copy program files to a newly created directory on your hard disk drive. Alternatively, you can use the program INSTALL.EXE which can be found on the 3.5 " disk. The installation program INSTALL.EXE creates a directory on your hard disk (C:\FLUXUS on default ) and copies all programs and associated files from the floppy disk onto it.

• Switch FLUXUS ON. Connect the COM-port (RS-232) of the PC and the 9-pin D-type connector at the r ear side of FLUX US with the supplied serial interface cable.

The utility program MOVEFAST.EXE copies the internal memory content of FLUX US to the memory of the Personal Computer via serial interface connection (FLUXUS works in slave mode). Then, the program creates a readable text file (an ASCII file which can easily be imported by PC programs like Excel) and a compressed binary file of the measured values (*.FLX). Both f iles are stored in the directory previously created. The file content can be visualised with any PC standard text or measur ement progr am (Excel, Lotus 1-2-3, DaDisp, etc.). T he program MOVEFAST.EXE is, therefore, being used for the OFFLINE data transfer of data already stored in FLUXUS.

MOVEDATA.EXE is a terminal program which allows the user to capture the data transmitted by FLUXUS with a PC and the store the inf ormation in a file. In this mode, FLUXUS generates the readable format and transfers the information to the PC. MOVEDATA.EXE is a utility program which makes the PC perform like an external printer. The data transfer is slower than it is when using MOVEFAST. But only a small proportion of the PC’s RAM capacity is being used. W ith the program MOVEDATA.EXE, the transfer of m easured data can either be performed ONLINE during measurement via the function

Measuring Data Transfer to PC

Print Meas.Val .

Special Funct.

S6 in program branch SPECIAL FUNCTIONS

(see chapter 7.)

Both programs (MOVEFAST.EXE and MOVEDATA.EXE) create ASCII-files of the measured values stored by FLUXUS. The format of the files is in both cases exactly the same. With any text processing program, the files can be visualised. This way, the information which the files contain can easily be displayed, processed and printed. Use a spreadsheet or other suitable program (Excel, Lotus 1-2-3, DaDisp, etc.) for further processing of the created ASCII - files.

With the utility program FLXtoTXT.EXE, the binary files (*.FLX), created by MOVEFAST.EXE, can be translated into ASCII -files with different form ats. For this, the PC, not FLUXUS, is used.

8.1 Utility Program MOVEFAST

Start the program MOVEFAST.EXE from the MS-DOS prompt using the following format :

SYNTAX:

movefast <OutputName> [/Cx] [<FormatO pt i ons> ]

PARAMETERS :

<OutputName> File name of the ASCII-file to be created. A file name must be

specified. The binary file being created will have the same name but with file extension ‘.FLX’.

/Cx

Specifies the serial port. Without specifying this parameter, COM2 will be used.

/C1=COM1 ... /C4=COM4

[<FormatOptions>] Specifies the format of the ASCII-file.

The available options are listed in chapter 8.3. If an option is not specified, the respective default value will be used. /xx+- means: /xx+ = option is on, /xx- = option is off.

Example:

movefast.exe data1.txt /C1 /SS+

The stored measured values are transmitted via serial interface COM1. The binary file ‘data1.flx’ and ASCII-file ‘data1.txt’ are created. Measured values will be separated with a semicolon character.

8.2 Utility Program FLXtoTXT

Use the program FLXtoTXT to generate an ASCII-file from the binary file, created by MOVEFAST:

SYNTAX:

flxtotxt <InputName> [<O ut put Name> ] [ < Format Options>]

PARAMETER :

<InputName> File name of the FLUXUS binary file. A file name must be

specified.

[<OutputName>] File name of the ASCII-file to be generated. If this parameter is

not specified, FLUXUS will use the file name of the binary file, but with the file extension ‘.TXT’.

[<FormatOptions>] Specifies the format of the ASCII-file.

The same formatting options are used as for MOVEFAST.

Example:

flxtotxt data1.flx data1b.txt /TRIM

The binary file ‘data1.flx’ will be converted to ASCII-file ‘data1b.txt’, which can be read by, e.g., text processing programs. The rows of measured data will be formatted without any space characters.

/C1=COM1 ... /C4=COM4 /N An existing file will be overwritten without asking for confirmation. /ONLY=n Output of measuring data set number n only. In case n is negative, the counting

starts from the end.

Without this parameter, all measuring data sets will be output.

/ONLY=3 output of measuring data set No. 3

/ONLY=

2 output of measuring data set which was stored before the last

one

/FP=n Every numerical value will be represented by n characters. (Default=9)

/FP=9 results in -1,00E+05 for -100380,37

/FP=10 results in t -100380,37 for -100380,37

The flow velocity, which the measured value was calculated f rom, will be additionally

output in the first column ('VELOC') in [m/s].

0,421;7,13;+3,22;-0,44; Flow Velocity=0,421 m/s

/M2+

Even when only one total count value is being stored in mem ory, 2 columns will be

generated in the output file ('Q_POS','Q_NEG'). (Default) /M2-

If during measurem ent the forward and r eturn total quantities have never been stored

simultaneously, only one column will be generated ('QUANT '). Positive values belong

to the forward total quantity, negative values belong to the return total quantity. /MM+

Always generates two columns for forward and return total quantities ('Q_POS',

'Q_NEG'). If no total quantity counts were stored in the row of measured values, the

columns are kept empty. /M2+- is ineffective. /MM-

Columns for forward and return total quantities are always omitted. /M2+- is

ineffective. /2T+

Even when only one temperature was stored, two columns ('T1','T2') will be

generated. /2T-

When only one temperature was stored, only one column will be generated. (Default) /D"+

Limits every line of the parameter record with quotation marks.

Super User Mode

9 Super User Mode

The Super User Mode gives you the opportunity for experimental work. In this operational mode,

YOU

, not FLUXUS, will be responsible and must decide:

•

upon the observance of the parameter ranges, characterised by physical and

specification limits;

•

upon the correctness of data inputs;

•

upon the meaningf ulness of measured values for measurements performed under

conditions which are outside the specification.

YOU

will need to take care that the measuring r esults are free f rom contradictions. In other words: FLUXUS operates in Super User Mode without observing pre-set standard parameters and limit values which normally guide you through the complexity of ultrasonic flow measurement.

9.1 Activation/Deactivation of the Super User

After entering the a. m. HotCode, this message appears which indicates that the Super User Mode is now passive. Confirm by pressing ENTER.

(The MAIN MENU will appear in standard mode.)

9.2 Super User Mode - Things worth mentioning

•

There are no plausibility checks when parameters are being enter ed.

•

There are no limit checks, and there is no control over the parameters so that they

are kept within the limits of physical laws and the specification.

•

The cut-off flow velocity is not active.

•

T he choice on how, during measurem ent, the sound path should go through the

pipe, is extended. The display M2 'Reflection Meas.' of program branch MEASURING changes accordingly

However, if the transducer type 'Special Version' is selected, the transducer parameters can be edited.

(See chapter 4.3.5)

9.5 Malfunctions during Super User Mode

Since the Super User Mode operates without any plausibility checks, malfunctions can occur under certain circumstances, which may result in an automatic switching-off of the instrument or in a crash of t he int ernal software.

For example, if you entered 0 (zero) as the number of sound paths in display M2 'Reflection Meas.', or if you specif ied an out side diameter of 0.1 mm.

Virtual Calculation Channels

10 Virtual Calculation Channels

10.1 Overview

In addition to the physically existing ultrasonic measuring channels (channels A and B) the FLUXUS ADM has two virtual calculation channels (channels Y and Z). These two ‘virtual’ channels mean that it is possible to perf or m simple operational calculations based on the two ultrasonic measuring channels, whilst the unit is in operation, e.g. channel A minus channel B. The results of this calculation are the measuring values of the virtual channel and can be treated in the same way as those readings produced from the standard channels, for example, totalisation, online output, storing, process outputs. The ability to perfor m these calculations is based on having input from two pairs of transducers via channels A and B.

10.2 Characteristics of the Calculation Channels

• The parameterisation of the virtual channels (program br anch >PARAMETER<) differs fr om the parameterisation of a physical channel. Instead of entering the parameters of the measuring point (i.e. pipe, medium), you simply have to decide on the type of calculation that you would like to perf or m.

• The calculation channels on the FLUXUS ADM are not automatically filtered. It is therefore necessary to set up the req uired damping separately for each of t he t wo measuring channels, (program br anch >OUTPUT OPTIONS<).

• It is possible to set up two sign-marked cut-off flows for each calculation channel. These cut-off flows are not based on the flow velocity (as physical channels do), but they are defined in the unit of measur em ent of that quantity of measurement, which was selected for the respective calculation channel (program br anch OUTPUT OPTIONS).

• A calculation value is compared with the set cut-off flows (and is set to 0.00 if necessary) before it is totalised.

• Process inputs, such as temperature inputs cannot be allocated to a calculation channel.

• It is not necessary to go through the transducer positioning sequence in order to configure the calculation channel, (p r ogram branch MEASURING).

• A virtual channel only gives valid results if valid measurements can be obtained from both physical channels.

• The stored measuring values of a calculation channel can be displayed or filed within the WINDOWS program FLUXDATA, (from version V1.1 onwards only). Older program versions display neither the stored measuring value nor the stored totalised values.

10.3 Parameterisation of the Calculatio n Channels

... FLUXUS firstly displays the actual calculation settings.

If required, it is possible to alter this by pressing any key.

Ch1>FUNCT<ch2 | |A| (+)/2 |B|

CH1

<: Select the first physical input channel.

CH2

<: Select the second physical input channel. >

FUNCT

< Select the calculation preferred.

The calculation function operates always sign-marked. Thus, you can select either the sign-marked measuring value of an input channel (A) or the absolute amount of t he measuring value (|A|) in each case >CH1< and >CH2<. All physical channels of the flowmeter are ready to be selected.

The following calculations can be set up:

Y:= CH1 - CH2

+ sum

Y:= CH1 + CH2

(+)/2 mean
