1.1 Function

Continuous level measurement with ultrasonic sensors is based on the running time measurement of ultrasonic pulses.

VEGASON series 54 … 56 sensors are a newly developed generation of extremely compact ultrasonic sensors for level measurement. They were especially developed for solids and larger measuring ranges. Preferred areas of application are silos, bunkers or material heaps.

Due to the small housing dimensions and process fittings, the compact sensors are a very reasonable solution for your level measurement applications. With the integrated display and a special sensor intelligence, in conjunction with large measuring ranges, they can be used for applications in which the advantages of a non-contact measurement could never before be realized.

As output or measuring signal, the instruments produce a digital output signal which is further processed in the VEGAMET signal conditioning instrument or in the VEGALOG processing system.

Measuring principle

Piezoceramic high performance transducers emit focused ultrasonic pulses which are reflected by the product surface. The measurement electronics prepares a precise picture of the environment out of the reflected ultrasonic pulses. The transducers work both as transmitter and receiver. As receiver, the transducers are high-sensitivity piezo microphones.

Product description

Meas. distance

emission - reflection - reception

The measurement electronics precisely calculates the distance between transducer and medium from the speed of sound and the measured running time of the emitted sound impulse. The distance is then converted into a level proportional signal, and in conjunction with the sensor parameter settings, made available as precise, calibrated level value.

Since the speed of sound is subjected to a temperature influence, the transducer also continuously detects the ambient temperature, so that the level is precisely measured even in case of varying ambient temperature.

Product description

Output signal

The level-proportional measuring signal is processed and outputted completely digitally. The digital processing of the measuring signal ensures an accuracy which could be never reached by an analogue measuring signal, as the digital signal is always transmitted up to the last decimal point.

Varying line resistances or smallest leakage currents do not influence the accuracy of the digital technology. Even in case of failure, the digital signal is always clear.

The parameter setting of the digital signal is individual and represents the adjusted measuring range of the sensor.

Display of measured values

As an option, the series 50 ultrasonic sensors can be equipped with an indicating instrument for direct, local level survey. The indicating instrument shows the precise level by means of the analogue bar graph and the digital number value. In addition to the indication in the sensor, you can have the level displayed with the VEGADIS 50 external indicating instrument at a distance of up to 25 m from the sensor. The external display of measured values operates, like the integrated display, independently of the output signal, can be modified through individual parameter settings, and is powered by the sensor.

1.3 Adjustment

Each measuring situation is unique. For that reason, every ultrasonic sensor needs some basic information on the application and the environment, e.g. an empty vessel profile is important for a reliable measurement. Beside this, many other settings and adjustments are possible on VEGASON ultrasonic sensors.

The adjustment and parameter setting of ultrasonic sensors are carried out with

- the PC

- the detachable adjustment module MINICOM

- the VEGAMET 514V or VEGAMET 515V signal conditioning instrument

Adjustment with PC

The setup and adjustment of the ultrasonic sensors is generally done on the PC with the adjustment program VEGA Visual Operating (VVO) under Windows®. The program leads quickly through the adjustment and parameter setting by means of pictures, graphics and process visualisations.

Adjustment with the PC to the digital signal and supply cable between the sensors and the VEGAMET signal conditioning instrument or on the sensor itself

The PC can be connected to any individual position of the system or the signal cable. It is connected by means of the two-wire PC interface converter VEGACONNECT 2 to the sensor, the signal cable or to the signal conditioning instrument or directly with a standard cable (RS 232) to the VEGALOG processing system.

The adjustment and parameter data can be saved with the adjustment software on the PC and can be protected by passwords. On request, the adjustments can be quickly transferred to other sensors.

2.1 Type survey

VEGASON series 54 … 56 sensors are a newly developed generation of extremely compact ultrasonic sensors for large measuring ranges. VEGASON 51 … 53 are used for shorter measuring ranges.

Due to the small housing dimensions and process fittings, the compact sensors do your level monitoring inconspicuously, and above all, at reasonable cost. Swivelling holders allow a quick alignment of the transducer to the product and solid surface. Mounting is simplified by the option of separating the sensor electronics from the transducer. The sensor electronics can be mounted at a distance of 300 m from the transducer. It is then possible to mount the transducer in environments with an ambient temperature up to 150°C.

Common features

• Four versions (A … D).

• Application is solids and liquids.

• Measuring range 0.8 m … 70 m.

• Ex approved in zone 1 (IEC) or zone 1

(ATEX) classification mark EEx ia [ia] IIC T6.

• Integrated display of measured values in the sensor or in the external indicating instrument separated up to 25 m from the sensor.

2.3 Approvals

When using ultrasonic sensors in Ex areas or in marine applications, the instruments must be suitable and approved for the explosion zones and application areas. The suitability is tested by approval authorities and is certified in approval documents.

VEGASON 50 ultrasonic sensors are approved for Ex zone 1, 10, 11, 21 and 22. Please note the attached approval documents when using a sensor in Ex area.

2.4 Configuration of measuring systems

A measuring system consists of a sensor and a processing unit. The processing unit ( the VEGAMET signal conditioning instrument or the VEGALOG processing system) evaluates the level-proportional digital measuring signals in a number of processing routines and outputs the levels as individual current, voltage or switching signals.

Two sensors can be connected via one twowire cable to the VEGAMET 515V signal conditioning instrument. Up to 255 sensors can be connected to the VEGALOG 571 processing system. 15 sensors (loop powered) on one two-wire cable.

Beside the output of the levels in percent, cubicmeters or other physical units, also current, voltage or switching signal (relay or transistor), the levels can be also processed by linked processing algorithms. Scaling, linearisation, calculation of linearisation curves, differential generation, addition or tendency processing are fixed implemented as processing routines in the VEGALOG processing systems and VEGAMET and are easily accessible via the menu.

On the following pages you find examples of two different instrument configurations (measuring systems) consisting of sensor(s) and processing system.

4.1 Mounting

Mounting and installation

Version A

Sensors in version A (flange version) are supplied completely mounted and ready for operation. Immediately after mounting on the vessel and electrical connection, they are ready for operation.

Version B

The sensors in version B are supplied in two parts (transducer and sensor electronics). First of all, mount the transducer on the vessel or above the medium. There is a four-pole jack at the end of the transducer tube. The respective counterpart to the jack protrudes out of the lower side of the sensor electronics housing. Insert the plug of the sensor electronics (only possible in one position), into the jack of the transducer tube. Continue pushing the electronics housing onto the transducer tube, on which there is a wide and a narrow groove.

Groove for locking the headless screw

Mounting groove (must no longer be visible after mounting)

The wide groove is used for locking the headless screws. The narrow groove is a marking for mounting. Move the electronics housing farther down over the transducer tube until the mounting groove is no longer visible. Fasten the housing with the headless screws to the transducer tube. Use a 5 mm hexagon screwdriver (or Allen wrench).

Mounting and installation

Version C and D

The sensors in version C and D are supplied in three parts (transducer, sensor electronics and transducer cable). First mount the transducer (see version B). There is a four-pole jack at the transducer tube end. A respective counterpart to the jack is provided in the connection cylinder of the transducer cable. Insert the connection cylinder plug into the jack of the transducer tube.

Connection cylinder

Mounting bracket

Connection cylinder

Transducer cable

On the end of the transducer tube you find a wide and a narrow groove. The wide groove is used for locking the cylinder with the headless screws. The narrow groove is the mounting mark.

Then push the connection cylinder onto the transducer tube (with a slight swivelling motion) until the mounting mark is no longer visible.

When the mounting mark is covered by the cylinder, fasten the cylinder with the two headless screws. Use a 5 mm hexagon screwdriver (or Allen wrench).

Now mount the sensor electronics in the requested location. The sensor electronics is fastened to a mounting bracket, so that it can be mounted to a plane surface or to the wall. Make sure that the sensor housing is mounted in such a way that there is enough space above the housing to open the cover.

Now insert the plug at the other end of the transducer cable into the jack on the electronics housing.

Note:

Avoid bending the transducer cable too sharply when laying it out. This is special cable which could otherwise be damaged.

In addition, make sure that the cable is not damaged during operation. A signal with a voltage of approx. 1 kV is transmitted (which could be a danger in Ex areas if the cable is damaged) is transmitted via the screened cable cones.

Beam angle and false echoes

At greater distances, the energy of the ultra-

sonic impulses distributes over a large area, The ultrasonic impulses are focused by the

transducer. The impulses leave the transducer in conical form similar to the beam pattern of a spotlight. The beam angle is 4°

thus causing weaker echoes from obstruct-

ing surfaces. The interfering signals are

therefore less critical than those at close

range. (VEGASON 54), 5° (VEGASON 55) and 6°

(VEGASON 56) at -3 dB emitted power. Any object, e.g. tubes or struts inside this emission cone will cause a false echo. Especially within the first few meters of the emis-

If possible, orient the sensor axis perpen-

dicularly to the product surface and avoid

vessel installations (e.g. pipes and struts)

within the 100 % area of the emission cone. sion cone, pipes, struts, or other installations

Therefore in practical application, the transducer has to be oriented so that lowest possible false echo signal strength is achieved. Just focussing a large useful echo is therefore not always sufficient. In most cases, a low false echo level enables the sensor to reliably pick up the useful echo. With the adjustment software VVO on the PC you can have a look at the echo image, see chapter "6.2 Adjustment with the PC“ under the subheading "Sensor optimisation/Echo curve“.

On dished tank ceilings, please do not mount the instrument in the centre, but approx. 1/ vessel radius from the centre. Dished tank ceilings can act as paraboloidal reflectors. If the transducer is placed at the focal point of the parabolic ceiling, the transducer receives amplified false echoes. The transducer should be mounted outside the focal point. Amplified echoes caused by parabolic surfaces are thereby avoided.

tube must have smooth walls inside (e.g. PE sewage pipe) and a diameter ³ 100 mm. This arrangement works well as long as the inside of the measuring tube collects no dirt or buildup (cleaning necessary). You might want to consider using hydrostatic pressure transmitters or capacitive measuring probes. Either the measuring tube should never be immersed in the medium, or it must always be immersed, so that the measurement is carried out exclusively in the tube.

The socket axis should point to the product surface. Much better would be the use of a swivelling holder version (type B, C).

4.5 Socket extensions

The ultrasonic sensors require a min. distance to the product or solid. Take the min. distance into account in your planning. In some situations, it is possible to reach the required min. distance, and hence the desired filling height, with a socket extension. However, the socket extension increases the noise level of the ultrasonic signal at the extension outlet and can interfere with the measurement. Only use a socket extension if all other possibilities have to be excluded. Carry out the extension as shown in the following illustration.

Socket extensions in liquids

Chamfer and deburr the socket carefully and make sure it has a smooth inner surface. The socket should not protrude into the measured product, in case buildup can form on the socket through pollution or product residues.

Material heaps

Large material heaps are detected with several instruments, which can be mounted on e.g. traverse cranes. For this type of application, it is best to orient the sensor toward the solid surface.

Socket piece should not be immersed into adhesive products (figure: VEGASON 53)

The socket diameter should be as large and the socket length as small as possible. Make sure that the socket outlet is burr-free to minimise false echoes.

Socket extensions for solids

For solids, use a conical socket extension with a taper of at least 15° … 20°.

4.6 False echoes

The mounting location of the ultrasonic sensor

must be selected such that no installations or

inflowing material are in the path of the ultra-

sonic impulses. The following examples and

instructions show the most frequent measur-

ing problems and how to avoid them.

Vessel protrusions

Vessel forms with flat protrusions can, due to

their strong false echoes, adversely effect

the measurement. Shields above these flat

protrusions scatter the false echoes and

guarantee a reliable measurement.

Correct Wrong

Vessel protrusions (slope)

Intake pipes, e.g. for the mixing of materials -

with a flat surface directed towards the sen-

sor - should be covered with a sloping

shield. This shield will scatter false echoes.

Correct Wrong

Measurement in a tube

For nonadhesive measured products, a socket extension in form of a measuring tube can be permanently submerged in the product. The ultrasonic measurement is then made exclusively in the measuring tube and works very well without interference from other vessel installations (see "Pump shaft“).

34 VEGASON 54V … 56V

Vessel protrusions (intake pipe)

Mounting and installation

Vessel installations

Vessel installations such as, for example, a ladder, often cause false echoes. Make sure when planning your measurement loop that the ultrasonic signals have free access to the measured product.

Correct Wrong

Ladder

Vessel installations

Ladder

Struts

Struts, like other vessel installations, can cause strong false echoes that are superimposed over the useful echo signals. Small shields effectively hinder a direct false echo reflection. These false echoes are scattered and diffused in the area and are then filtered out as "echo noise“ by the measuring electronics.

Correct Wrong

Shields

Inflowing material

Do not mount the instrument in or above the filling stream. Ensure that you detect the product surface and not the inflowing material.

Correct

Buildup

If the sensor is mounted too close to the vessel wall, buildup and adhesions of the measured product to the vessel wall can cause false echoes. Position the sensor at a sufficient distance from the vessel wall. Please also note chapter "4.2 General installation instructions“.

Strong product movements

Heavy turbulences in the vessel, e.g. by strong stirrers or strong chemical reactions, seriously interfere with the measurement. A surge or bypass tube of sufficient size (DN 200, DN 250) always allows, provided the product causes no buildup in the tube, a reliable measurement even with strong turbulences in the vessel.

100 %

4.7 Incorrect mounting

Foam generation

Thick foam on the product can cause incor-

rect measurements. Take measures to avoid

foam, carry out the measurement in a bypass

tube, or use a different measuring technol-

ogy, e.g. capacitive measuring probes or

hydrostatic pressure transmitters.

Foam generation

Wrong orientation to the product

Weak measuring signals are the result if the

sensor is not directly pointed at the product

surface. Orient the sensor axis perpendicu-

larly to the product surface to achieve opti-

mum measuring results.

Min. distance to the medium

If the min. distance to the medium is not maintained, the instruments show wrong measured values. Mount the instrument at the required min. distance.

Sensor too close to the vessel wall

Correct Wrong

If the sensor is mounted too close to the vessel wall (dimension A in diagram), strong false echoes can be caused. Buildup, rivets, screws or weld joints on the vessel wall superimpose their echoes to the product or useful echo. Please ensure the sufficient distance of the sensor to the vessel wall, depending on the maximum measuring distance (dimension B in diagram). In case of good reflection conditions (liquids, no vessel installations), we recommend determining the sensor distance according to Diagram curve

1. At a max. meas. distance of e.g. 10 m, the distance of the transducer (according to curve 1) should be approx. 1.5 m. In case of solids with bad reflection properties, determine the distance to the vessel wall according to Diagram curve 2. Under very bad measuring conditions (rough vessel walls, struts), it might be necessary, to increase the distance to the vessel wall, or to filter out the false echoes in addition by storing them in memory, thereby adapting the sensor more precisely to the environment.

Parabolic effects of rounded or arched vessel tops

Round or parabolic tank tops act like a parabolic mirror for the signals. If the sensor is placed at the focal point of such a parabolic tank top, the sensor receives amplified false echoes. The optimum location is generally in the area of half the vessel radius from the centre.

5.1 Connection and connection cable

Safety information

As a rule, do the work in the complete absence of voltage. Always switch off the power supply before you carry out connecting work on the ultrasonic sensors. Protect yourself and the instruments, especially when using sensors which do not operate with low voltage.

Qualified personnel

Instruments which are not operated with protective low voltage or DC voltage must only be connected by qualified personnel.

Connection

A standard two or four-wire cable (sensors with separate supply) with max. 2.5 mm2 can be used for connection. Please note that the connection cables are specified for the expected operating temperatures in your systems. The cable must have an outer diameter of 5 … 9 mm or 3.6 … 8.6 mm, to ensure the seal effect of the cable entry.

Transducer cable

When wiring the transducer cable, avoid strong bending of the cable. This is a special cable which will otherwise be damaged.

Make sure that the cable will not be damaged during operation. The screened transducer cables transmit a signal with a voltage of approx. 1 kV. In Ex areas, a cable damage can be dangerous.

Earth conductor terminal

The electronics housing of the sensors has a protective insulation. The earth conductor terminal and the earth terminal in the electronics housing are galvanically connected with the metallic transducer diaphragm. On sensors in version B, the earth conductor terminal is galvanically connected to the transducer diaphragm via the transducer tube when the sensor is completely mounted. On version C and D, the connection is made via the cable screen of the transducer cable and the transducer tube.

> 0,1µF 250 V AC

Shielding of the sensor cables

The "Electromagnetic pollution“ from electronic actuators, power lines and transmitting stations is often so considerable that the sensor cable should be shielded.

We recommend a screening on both ends. Screening is a good preventative measure against future sources of interference. However, you must make sure that no ground potential currents flow through the sensor cable shields. Ground potential currents can

VEGAMET

515V

be avoided by potential equalisation cables. When grounding at both ends, it is possible to connect the cable shield on one side (e.g. in the switching cabinet) via a capacitor (e.g.

0.1 µF; 250 V) to the ground potential. Use a low-resistance ground connection (foundation, plate or mains earth).

Note Ex protection!

In Ex applications, grounding on both ends is not allowed due to potential losses. If an instrument is used in hazardous areas, the respective regulations, conformity certificates and type approvals for systems in Ex areas must be noted (e.g. DIN 0165).

Please note the approval documents with the safety data sheet attached to the Ex sensors.

The sensor lid with the optional indication display can then be opened. Unscrew the sleeve nut and slip it over the connection cable (after removing about 10 cm of insulation). The sleeve nut of the cable entry has a self-locking ratchet that prevents it from opening on its own.

6.1 Adjustment methods

VEGASON 51V … 56V ultrasonic sensors can be adjusted with

- PC (adjustment program VVO)

- detachable adjustment module

MINICOM or

- VEGAMET signal conditioning instrument.

The adjustment must only be carried out with one adjustment device.

With the PC

The PC with the adjustment program VVO (VEGA Visual Operating) can be connected to:

- the sensor

- the signal cable

- the VEGAMET 514V, 515V signal

conditioning instrument

- the VEGALOG 571 processing system

With the adjustment program VVO (VEGA Visual Operating System) on the PC you can adjust the ultrasonic sensors very comfortably. The PC communicates via the interface adapter VEGACONNECT 2 with the sensor and the signal conditioning instrument or with the standard RS 232 interface cable to the VEGALOG processing system and all connected sensors. A digital adjustment signal is superimposed on the signal and supply cable. The adjustment can be carried out directly on the sensor or at any desired location along the signal cable or on the processing system VEGAMET or VEGALOG.

In the following chapter "6.2 Adjustment with the PC on VEGAMET“, the adjustment is described when connecting the PC via the VEGACONNECT on VEGAMET. When connecting the PC via VEGACONNECT to the sensor signal cable (see "2.4 Configuration of measuring systems“), all sensors connected to the affected signal cable are available for adjustment. However, the configuration and measured data processing functions of VEGAMET are not available.

When inserting VEGACONNECT into the communication socket of an individual sensor, only sensor-relevant adjustment options such as e.g. sensor optimisation on the affected sensor are adjustable. Other sensors and VEGAMET are then not adjustable. This is due to an adjustment hierarchy beginning with VEGAMET or VEGALOG and ending with the sensor.

With the VEGAMET signal conditioning instrument

Sensor and VEGAMET signal conditioning instrument can be operated as with the adjustment program VVO with the 6 key adjustment field on the signal conditioning instrument. The adjustment is possible in the same function volume as with the adjustment program VVO on the PC.

With the adjustment module MINICOM

With the adjustment module MINICOM you adjust the individual sensor directly in the sensor or in the external indicating instrument VEGADIS 50. The adjustment module MINICOM with the 6 key adjustment field with text display enables the parameter adjustment of the sensor with an array of functions comparable to the adjustment program VVO or the VEGAMET signal conditioning instrument, however not the configuration of the measuring system.

The adjustment with the signal conditioning instrument is only possible with the adjustment program VVO or the 6 key adjustment field on the signal conditioning instrument.

VEGASON 54V … 56V 45

Setup

6.2 Adjustment with the PC on VEGAMET

For connection of the PC to the signal conditioning instrument, the interface converter VEGACONNECT 2 is required. The PC communicates via the interface converter with the signal conditioning instrument and the connected sensor(s).

In the following setup and adjustment instructions you will find information on the following topics and adjustment points:

• Configuration

- create new measurement loop

- configuration info

• Parameter adjustment 1

- adjustment

- scaling

• Sensor optimisation

- meas. environment

- sound velocity

- echo curve

- false echo storage

- measurement loop data

• Parameter adjustment 2 (optional)

- linearisation

- parameter adjustment outputs

• Display of measured value

• Simulation

• Backup

Note:

Keep in mind that you first have to log in a sensor in the configuration menu before you can continue with the parameter setting, and if necessary, carry out adjustments in the menu “Sensor optimisation”.

Beside the measured values, the adjustments signals are also transmitted digitally via the signal supply cable between sensor and VEGAMET. The adjustment program VVO can then communicate with VEGAMET and all connected sensors. In chapter "2.4 Configuration of measuring systems“ the connection of the PC to the different sensor arrangements is shown.

Before starting the setup:

Do not be confused by the many pictures, adjustment steps and menus on the following pages. Just carry out the setup with the PC step-by-step and you will soon no longer need the following pages. Whenever you should adjust or choose something, this is indicated in the following by a large black dot, like this:

• Choose …

• Start …

• Click to …

• Connect the standard output of your PC by

the standard RS 232 interlink cable (9pole) to VEGALOG.

• Now switch on the power supply of the processing system.

By this means, the actions to be carried out are clearly separated from supplementary information in the following adjustment instructions.

Start now:

• Connect the standard plug of VEGACONNECT 2 (9-pole) to the interface COM 1 or COM 2 of your PC.

• Insert the two small pin plugs of VEGACONNECT 2 into the CONNECT sockets on the front of the signal conditioning instrument.

• Now switch on the power supply of the signal conditioning instrument.

After approx. 1 … 2 minutes (self-test) the measuring system generally show the operating condition and the measured value.

• Now start the adjustment software VVO on your PC.

Configuration

During the setup of the measuring system you are confronted with two terms: "Configuration“ and "Parameter adjustment“. The meas. system is first set up with a configuration and then with a parameter adjustment.

Configuration

The term "Configuration“ means the basic adjustments of VEGAMET. You inform VEGAMET about the application (level measurement, gauge, distance …), the measurement loop name and the input channel. The configuration corresponds to an electronic wiring and labelling of your VEGAMET or just which sensor for what application and where.

Parameter adjustment

After the configuration, you carry out the parameter adjustment for each individual sensor. This means, to adjust the sensors to the respective operating range and to adjust to the actual application. You inform the sensor which product distance (which level) is "empty“ and which "full“. This is called adjustment. Here you choose in which physical unit (volume, mass) and unit of measurement (m3, gal, liters …) the adjusted measured value should be outputted. In the submenu "Sensor optimisation“ you inform the sensor electronics about the actual environment, such as e.g. quick changes of the measured value, foam generation, gas stratification, solid or liquid.

there are 576 liters in the vessel (in our example). Index marker 3 is at a filling level of 60 %. At this filling level there are 646 liters in the vessel. Index marker 4 is at a filling level of 100 % (product distance 1.270 m), where 1200 liters are in the vessel.

6.3 Adjustment with the adjustment module MINICOM

Beside the PC, the ultrasonic sensors VEGASON 54V … 56V can also be adjusted with

- the signal conditioning instrument

- or detachable adjustment module MINI-

COM.

For the adjustment with VEGAMET signal conditioning instrument all adjustment options as with the PC are available. The adjustment, however, is different in the appearance, but not in the functions.

With the adjustment module MINICOM only the sensor-relevant adjustment are possible, such as e.g. adjustment, operating range, measuring conditions, sensor scaling or false echo memory. However, all adjustment steps relating to the configuration of the VEGAMET signal conditioning instrument and their signal processing (configuration of the inputs and outputs, linearisation curves, simulation …) are not possible.

The adjustment of VEGAMET and MINICOM is identical. Adjustment is made with six keys. A small display shows you, apart from the measured value, a short message on the menu item or on the value of a menu adjustment.

The information volume of the small display, however, cannot be compared with that of the adjustment program VVO, but in conjunction with the following menu schematic of VEGAMET 515V and MINICOM the adjustment will not be a problem. Perhaps the adjustments can be carried out more quickly and directly with the small adjustment field than with the PC.

Adjustment steps

On page 72 … 79 you can find the complete menu schematic of the VEGAMET 515V signal conditioning instrument as well as of the adjustment module MINICOM. The menu schematic of the VEGAMET 514V signal conditioning instrument is nearly identical. Set up the sensor in the numbered sequence. The respective numbers are stated in the menu schematics. The items in brackets can be adjusted beside the VEGAMET signal conditioning instrument also with the adjustment module MINICOM.

Short explanations to the setup steps 1 … 11 follow.

1. Configuration of the input

First of all, you have to inform the signal conditioning instrument (only VEGAMET 515V) to which input (input 1 or 2) the sensor is connected.

2. Configuration of the measurement loop

(see menu schematic page 74)

3. Measurement in gases

Adjustment is only necessary when the measurement is made in gases (Co2, He, etc.) deviating from air. In case of measurement in gases, sound the distance of the sensor to the product surface and enter it in the menu item "Measurement in gases“. The sensor can then take the modified sonic velocity in gases (as opposed to air) and output correct levels.

4. Operating range

Without special adjustment, the operating range corresponds to the measuring range. The measuring range has already been adjusted with the min./max. adjustment. Generally it is useful to choose a slightly bigger (approx. 5 %) operating range than the measuring range.

Example: Min./max. adjustment: 0.500 … 3.500 m; adjust operating range to approx.

0.400 … 3.600 m.

5. Meas. conditions

(max. adjustment)

The max. adjustment (upper product distance) is made in the same way (example: 100 % and 1.270 m).

Note:

The difference between the adjustment values of the lower product distance and the upper product distance should be as big as possible, preferably at 0 % and 100 %. If the values are very close together, e.g. lower product distance indication at 40 % (3,102 m) and upper product distance adjustment at 45 % (3.331 m), the measurement will be inaccurate. A characteristics curve is generated from the two points. Even the smallest deviations between actual product distance and entered product distance will considerably influence the slope of the characteristic curve. When the adjustment points are too close together, small errors multiply to considerably larger errors at the output of the 0 % or the 100 % value.

Fill the vessel e.g. to 10 % and enter 10 % in the menu "

The creation of one’s own linearisation curve is only possible with the PC and the adjustment program VVO.

9. Useful and noise level

In the menu

you get important information on the signal quality of the product echo. The higher the "S-N“ value, the more reliable the measurement (menu diagram MINICOM).

Ampl.: means amplitude of the level echo in

dB (useful level)

S-N: means Signal-Noise, i.e. the useful

level minus the level of the background noise

The bigger the "S-N“ value (difference between the amplitude useful level and the noise level), the better the measurement: > 50 dB Measurement excellent 40 … 50 dB Measurement very good 20 … 40 dB Measurement good 10 … 20 dB Measurement satisfactory 5 … 10 dB Measurement sufficient < 5 dB Measurement poor

Example::

Ampl. = 68 dB S-N = 53 dB

68 dB – 53 dB = 15 dB noise level

53 dB signal level difference indicates very high measurement reliability.

8. False echo storage

10. Conditioning/Scaling of the sensor display

A false echo storage is always useful when unavoidable false echo sources (e.g. struts) must be minimised. By creating a false echo storage, you authorise the sensor electronics to note the false echoes and save them in an internal database. The sensor electronics treats these (false) echoes differently from the useful echoes and filters them out.

Beside the measured values, also adjustment signals are transmitted digitally between sensor and processing system via the signal and supply cable. The adjustment program VVO can then communicate with the processing system and all connected sensors. In chapter „2.4 Configuration of measuring systems“ the connection of the PC to the different configurations is shown.

The individual adjustment steps are marked in the following with a dot. Example:

• Choose …

• Start …

• Click to …

After approx. 1 … 2 minutes (selftest) the measuring system consisting of processing system and sensors is in operating condition and the sensors display measured values. i

• Now start the adjustment software VVO on your PC.

• Choose with the arrow keys or the mouse the item "

Planning

“ on the entrance screen

and click to „OK“.

In the next window, you are asked for the user identification.

• Enter under name "VEGA.

• Also enter "VEGA under password.

The first steps of the setup wit the PC in conjunction with the VEGALOG processing system correspond to the adjustment in chapter „6.3 Adjustment with VEGAMET or MINICOM“.

• Connect the standard interface of your PC by the standard RS 232 interlink cable (9pole) to the VEGALOG processing system.

• Now switch on the power supply of the processing system.

Setup - Adjustment with the PC on VEGALOG

The adjustment program VEGA Visual Operating (VVO), called in the following VVO, gets into contact with the connected sensor and indicates after a few seconds if and with which sensor a connection exists.

Note:

If you make no connection with the sensor, check the following:

Configu-

Independent whether you set up a measuring system (unit consisting of sensor and VEGAMET signal conditioning instrument or VEGALOG processing system) with the adjustment software VVO or with the signal conditioning instrument, the adjustment procedure is always the same:

- first of all crease a measurement loop and configure a measuring system in the menu

„

Configuration

“ and then

- carry out the parameter adjustment of the sensor in the menu „

Instrument data

“.

Configuration

The adjustment of an ultrasonic sensor with the PC on a VEGALOG generally corresponds to the adjustment of an ultrasonic sensor on the signal conditioning instrument, as in chapter „6.2 Adjustment with the PC on VEGAMET“.

The only difference is the increased configuration requirement of VEGALOG. A number of possible sensor inputs and signal output as well as different processing routines must be assigned. First of all it must be defined where and what processing which sensor (input) does.

Now the sensor electronics has two characteristics points, one for min. and one for max., out of which a linear correlation between product distance and the percentage filling of a vessel is generated. Naturally the characteristics point must not be at 0 % and 100 %, however the distance should be as big as possible (e.g. at 20 % and at 80 %). The difference between the characteristics points for the min./max. adjustment should be at least 50 mm product distance.

0 % and 100 % values of the parameter and their unit. You thereby inform the sensor, e.g. that at 0 % filling there are still 45 liters and at 100 % filling 1200 liters in the vessel. The sensor display then shows with empty vessel (0 %) 45 liters and with full vessel (100 %) 1200 liters.

Diagnostics

7 Diagnostics

7.1 Simulation

For simulation of a certain filling, you can call up the function "Simulation“ on the adjustment module MINICOM, in the software program VVO or on the signal conditioning instrument.

You simulate a vessel filling and thereby a certain sensor current. Please note that connected instruments, such as e.g. a PLC react according to their adjustments and will probably activate alarms or system functions.

Simulation with VVO

If you start the simulation mode with the adjustment program VVO on the PC, the simulated level is outputted until you quit the simulation mode.

Simulation with VEGAMET

If you call up the simulation mode with the adjustment keys on the signal conditioning instrument, 15 minutes after the last adjustment, the signal conditioning instrument returns again to standard operating condition.

Simulation with MINICOM

If you start the simulation mode on the adjustment module MINICOM, the sensor returns to standard operating mode after one hour.
