1 Product description

1.1 Function

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

Measuring principle:

Piezoceramic high-performance transducers emit focussed ultrasonic pulses reflected from the surface of solids and liquids. The meas. signal prepares a precise picture of the meas. environment out of the running time and signal shape of the reflected ultrasonic pulses. The transducers operate as emitter and receiver. As receiver the transducers are high sensitivity piezomicrophones.

Meas. distance

Product description - Function

Out of the physical sound velocity and the detected actual running time of the emitted sound impulses, the meas. electronics calculates precisely the distance between transducer and product. The distance is converted into a level proportional meas. signal and provided acc. to the sensor parameter adjustment as exact scaled level. The instruments operate with emitting frequencies from 34 kHz to 70 kHz to be prepared for the different distances and requirements.

As the sound velocity is subjected to a temperature influence, the transducer detects continuously the ambient temperature so that the level is provided precisely even with varying ambient temperature.

Product description - Application feature

Output signal

The level proportional meas. signal is either processed in the ultrasonic instrument itself or in the connected signal conditioning instrument and provided as output signal. In digital technology varying line resistances or smallest leakage currents have no influence to the accuracy. The digital signal is always clear.

Individual parameter adjustment of the digital signal is possible and the signal always reflects the adjusted meas. range of the sensor.

Measured value indication

An indicating instrument for direct, local level survey is integrated in the series 50 ultrasonic sensors. The indicating instrument shows with the analogue bargraph immediately the level and with the digital figure value precisely the level. Additionally to the indication in the sensor, the level can be indicated with the external indicating instrument VEGADIS 50 separated up to 25 m from the sensor. The external measured value indication like the integral indication works completely independent from the output signal and individual parameter adjustment is possible.

1.2 Application feature

Applications

1.3 Adjustment

Each measuring distance is different, hence each ultrasonic sensor must be given some basic information on the application and the environment. E.g. you inform the sensor which level means "empty" and which level "full". Beside this "Empty and full adjustment" also a number of other adjustments can be carried out with VEGASON ultrasonic sensors.

The adjustment and parameter adjustment of the ultrasonic sensors are hence carried out with:

- the PC

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

- the detachable adjustment module MINICOM

Product description - Adjustment

Adjustment with PC

The set-up and adjustment of the ultrasonic sensors is generally made on the PC with the adjustment program VVO (VEGA Visual Operating) under Windows®. The program leads quickly through the adjustment and parameter adjustment via pictures, graphics and process visualizations.

Adjustment with PC on the digital signal and supply line between the sensors and the signal conditioning instrument VEGAMET or on the sensor itself (figure: VEGASON 51 V)

The PC can be connected to any individual position of the system or the signal line. It is hence connected with the two-wire PC-interface converter VEGACONNECT 2 to the sensor, the signal line or to the signal conditioning instrument, but also with a standard cable (RS232) directly to the processing system VEGALOG.

The adjustment and parameter adjustment data can be saved with the adjustment software on the PC and protected with passwords. If required the adjustments can be transferred quickly to other sensors.

2.1 Survey

VEGASON series 50 sensors are a newly developed generation of very compact, small ultrasonic sensors. With very narrow space requirements, they are designed for short meas. distances (0 ... 15 m) and for standard applications such as storage tanks, gauge measurement and buffer tanks.

Due to the small housing dimensions and process connections the compact sensors monitor very price favourable your levels. With the integral indication and the many features of the "big brothers" of VEGASON series 80, they open the advantages of an ultrasonic measurement for applications where the special advantages of a non-contact measurement were not applicable due to price reasons.

VEGASON 50 ultrasonic sensors dominate the two-wire technology perfectly. The supply voltage and the digital output signal are transmitted via one two-wire line to the connected signal conditioning instrument VEGAMET or the processing system VEGALOG.

Types and versions - Configuration of measuring systems

2.2 Configuration of measuring systems

A measuring system consists of a sensor and a processing unit. The processing unit (signal conditioning instrument VEGAMET or processing system VEGALOG) processes the level proportional digital meas. signals and evaluates these in a number of processing routines. The levels can then be provided as current, voltage or switching signals and further processed, e.g. in a weir control. On the following pages you see the different instrument configurations called measuring systems which are shown in the following partly with a signal processing.

Meas. systems in two-wire technology:

• 2 sensors on one two-wire line

(page 13)

• 2 sensors in Ex on one two-wire line

(page 14)

• 15 sensors on one two-wire line

(page 15)

• 3 sensors in Ex on one two-wire line

(page 16)

Series 50 sensors require for operation in Exareas the Ex-separator VEGATRENN 548 V Ex, providing intrinsically safe Ex-circuits.

Note to page 14 and 16:

Sensor lines should be looped in screened cables. It is suitable to earth the cable screens on both ends. However it must be noted that no earth compensation currents flow via the screens.

Earth compensation currents can be avoided with earthing on both ends by connecting the cable screen on one earth end (e.g. in the switching cabinet) via a capacitor (e.g. 1 µF, 100 V) to the earth potential.

Sensor lines leading to the same separator card, can be looped together in one screened multiple wire cable. Sensor lines leading to other separator cards, must be looped in separate, screened cables.

Technical data - Approvals

3.2 Approvals

When using ultrasonic sensors in Ex-areas the instruments must be suitable and approved for these explosion zones and applications. For the use on ships special type approval certificates are available. In hazardous areas (due to gases, vapours, fog and dusts) only appropriately approved instruments must be used. The suitability is checked by the approval authorities and is certified in approval documents.

VEGASON 51 V Ex and VEGASON 52 V Ex sensors must be powered for the use in Exzone from one intrinsically safe circuit. This is ensured by the separator VEGATRENN 548 V Ex. The separator provides intrinsically (ia) circuits. The resistance of the signal line must not exceed 15 Ω per wire.

VEGASON 51 V Ex and VEGASON 52 V Ex sensors are approved for Ex-zone 1. VEGASON 53 V ExS is approved for Exzone 10 or zone 21. As proof for the Ex-approval appropriate confirmity certificates and type approval certificates of the approval authorities are attached to the sensors.

Beam angle and false echoes

The ultrasonic impulses are focussed by the transducer. The impulses leave the transducer in conical form similar to the beam pattern of a spotlight. The beam angle is 5,5° (type 51/52) or 3° (type 53) at -3 dB emitted power.

Any object in this beam angle causes a false echo. Within the first few metres of the beam angle, tubes, struts or other installations cause strong false echoes. In a distance of 2 m the false echo of a strut has 9-times more amplitude than at a distance of 6 m.

If possible, provide a vertical directing of the sensor axis to the product surface and avoid if possible, struts within the 100%-beam angle, e.g. by tubes and struts.

Dished tank ends

On dished tank ends please do not mount the instrument in the centre but approx. 1/2 vessel radius from the centre. Dished tank ends can act for the ultrasonic pulses as paraboloidal refelctors. If the transducer is placed in the "focus" of the parabolic tank end, the transducer receives amplified false echoes. Hence the transducer should be mounted outside the "focus". Parabolic amplified false echoes are hence avoided.

4.4 Socket extensions

The ultrasonic sensor requires a min. distance to the product or solid. Note this min. distance in your planning. In exceptions it is possible to reach the required min. distance and hence the desired filling height with a socket piece. However the socket piece increases the noise level of the ultrasonic signal and can interfere the measurement. Only provide the socket extension when there is no other possibility and carry out the extension as shown in the following figure.

Socket extensions with liquids

Chamfer the socket carefully and ensure a smooth inner side of the socket. The socket should not protrude into the measured product when pollution or measured product could stick to the socket.

4.6 False echoes

The installation place of the ultrasonic sensor must be selected such that no installations or inflowing material cross the ultrasonic impulses. The following examples and instructions show frequent meas. problems and how they can be avoided.

Shoulders

Vessel forms with flat shoulder can aggravate the measurement due to the strong false echoes. Shields above these flat shoulders spread the false echoes and ensure reliable measurement.

Correct Wrong

Shoulders

Inlets, e.g. for material mixing with flat upper side pointing to the sensor, should be covered by an angle shield. The false echo is hence gated out.

Correct Wrong

Mounting and installation - False echoes

Vessel installations

Vessel installations such as e.g. a ladder often cause false echoes. Note when planning your measurement loop that the ultrasonic signals should reach the product without problems.

Correct Wrong

Ladder

Vessel installations

Ladder

Struts

Struts such as vessel installations can cause strong false echoes which can overlay the useful echo. Small shields avoid a direct false echo reflection. The false echoes are diffused and filtered out by the meas. electronics as "echo noise".

Mounting and installation - Installation error

Sensor too close to the vessel wall

Correct Wrong

Sensor too close to the vessel wall

If the sensor is mounted too close to the vessel wall (dimension A in diagram) strong false echoes can be caused. Build-up, rivets, screws and weld joints superimpose their echoes to the product echo or useful echo. Hence note a sufficient distance of the sensor to the vessel wall dependent on the max. meas. distance (dimension B in diagram). In case of good reflection conditions (liquids, no vessel installation) we recommend to provide 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 would be approx. 1 m.

In case of solids with bad reflection conditions provide a distance to the vessel wall according to diagram curve 2. With very bad meas. conditions it can be necessary to increase the distance to the vessel wall or to gate out the false echoes additionally by a false echo storage and hence to adapt the sensor more precisely to the environment.

5 Electrical connection

5.1 Connection and connection cable

Safety information

Ensure that the instrument is unpressurized before you start work. Always switch off the power supply before you carry out clamping work on the ultrasonic sensors. Protect yourself and the instruments.

Electrical connection

Ex-protection

If an instrument is used in hazardous areas the appropriate regulations, conformity certificates and type approvals of the sensors and separators or safety barriers must be noted (e.g. DIN VDE 0165).

Skilled staff

Instruments which are operated in Ex-areas must only be connected by skilled staff. The skilled staff must know the installation conditions and note the attached type approval and conformity certificates.

Connection

A standard two-wire cable with max. 2,5 mm can be used for connection. Very often the "electromagnetic pollution" by electronic actuators, energy lines and transmitting stations is so considerable that the two-wire line should be screened.

We recommend to use a screening. This screening prevents against future interferences. It is suitable to earth the cable screens on both ends. However it must be noted that no earth compensation currents flow via the screens.

Sensors which are used in Ex-areas must only be operated on intrinsically safe circuits. The permissible electrical values are stated in the conformity certificate or the type approval.

Connection cable

Note that the connection cable must be speci-

fied for the expected operating temperatures in your systems. The cable must have an outer diameter of 5 … 9 mm otherwise the seal effect of the cable entry will not be ensured.

Cables for intrinsically safe circuits must be marked blue and must not be used for other circuits.

Earth conductor terminal

On VEGASON 51/52 sensors the earth conductor terminal is galvanically isolated. On VEGASON 53 sensor the earth conductor terminal is galvanically connected to the metal transducer diaphragm.

Note: In Ex-applications the cable screen of the connection cable must only be earthed at one end.

38 VEGASON 51 V … 53 V

Electrical connection - Connection of the sensor

5.2 Connection of the sensor

After having mounted the sensor in the meas. position according to the instructions in chapter "4 Mounting and installation", loosen the closing screw on the top of the sensor. The sensor cover with the optional indication display can then be opened. Unscrew the compression screw and shift the screw over the approx. 10 cm dismantled connection cable. The compression screw of the cable entry is protected with a safety lock-in position against automatic loosening.

Supply voltage and digital meas. signal

Now loop the cable through the cable entry into the sensor. Screw the compression screw to the cable entry and clamp the dismantled wires of the cable to the appropriate terminal positions. The terminals operate without terminal screw. Press the white opening buckets with a small screwdriver and insert the copper core of the connection line into the terminal opening. Check the position of the lines in the terminal position by slightly pulling on the connection lines.

Set-up - Adjustment structure

6 Set-up

6.1 Adjustment structure

Series 50 ultrasonic sensors can be adjusted with

- PC (adjustment program VVO)

- detachable adjustment module MINICOM

- signal conditioning instrument VEGAMET.

Signal conditioning instrument VEGAMET

The signal conditioning instrument VEGAMET allows with the 6-key adjustment field with text display the parameter adjustment in the same functional spectrum than the adjustment program VVO on the PC.

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

Adjustment program VVO

With the adjustment program VVO (VEGA Visual Operating) on the PC you adjust the ultrasonic sensors very comfortably. The PC communicates via the interface adapter VEGACONNECT 2 or the standard RS232 interface cable digitally with the sensor. The adjustment can be carried out hence directly on the sensor, at any position of the signal line or on the processing system VEGAMET/ VEGALOG.

Note: The adjustment with the PC via the interface adapter VEGACONNECT 2 directly on the sensor or on the signal line only allows the "

Configuration

" and corresponds to

" are not possible with

Adjustment module MINICOM

With the adjustment module MINICOM you adjust in the sensor or in the external indicating instrument VEGADIS 50. The adjustment module ensures with the 6-key adjustment field with text display the parameter adjustment in the same functional spectrum like the adjustment program VVO or the 6-key adjustment field with text display on the signal conditioning instrument VEGAMET.

The configuration adjustments however are only possible with the adjustment program VVO or the 6-key adjustment field with text display on the signal conditioning instrument VEGAMET.

Independent whether you carry out the setup of a meas. system (consisting of sensor and signal conditioning instrument VEGAMET or sensor and processing system VEGALOG) with the adjustment software VVO, with the signal conditioning instrument or with the adjustment module MINICOM, the way is always the same:

- Configure first a meas. system in the menu "

Configuration

- carry out the parameter adjustment of the sensors in the menu "

" and

Instrument data

VEGASON 51 V … 53 V 41

Configuration means to coordinate or deter mine once. In the menu Configuration the signal conditioning instrument is informed about the general configuration:

- which kind of sensor is connected (radar, ultrasonic, process pressure…),

- what kind of parameter or application is concerned (level, gauge, distance…)

- to which input the sensor is connected

- which outputs (current, voltage, relay, fault signals, indication…) should be coordinated to which input in which way (inverted, threshold value controlled…).

After these adjustments (configuration) had been carried out, the meas. system goes to operating condition and the signal conditioning instrument will display a measured value. Now the sensor parameter adjustment (adjustment, unit, linearisation curve, sensor adaption…) can be carried out.

Parameter adjustment means to enter values. Parameters are entered in the signal conditioning instrument as well as in the connected sensors. For example:

- Min. and max. adjustment

- Meas. range limits

- Physical unit, decimal point

- Linearisation curves

- Integration time

- Meas. environment (solid, liquid, foam generation, operating range…)

- False echo memory

- Inversion of the measured value etc.

Now all required adjustments for a precisely adapted sensor are carried out for a reliable measurement.

Set-up - Adjustment with PC on VEGAMET

6.2 Adjustment with PC on VEGAMET

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

- to the sensor

- to the signal line

- to the signal conditioning instrument

VEGAMET 514V/515V

- to the processing system VEGALOG 571

For connection of a PC to a signal conditioning instrument you require the interface adapter VEGACONNECT 2. The PC communicates via the interface adapter VEGACONNECT 2 with the signal conditioning instrument and the sensor. Hence a digital adjustment signal is superimposed to the signal and supply line between sensor and signal conditioning instrument. In chapter "2.2 Configuration of measuring systems" the connection of the PC in different coordinations is shown.

Before starting the set-up:

Take some time to carry out the set-up stepby-step with the PC and soon you will no more require the following pages.

Hence the sensor electronics has two characteristics points (MIN and MAX), out of which a linear proportionality between product distance and the percentage filling of a vessel is generated. However the characteristics points must not be at 0 % and 100 % but the difference should be as large as possible (e.g. at 20 % and at 80 %). The min. product distance of the characteristics point for min./max. adjustment should be 50 mm. When the characteristics points are too close together, the possible meas. error increases. It is hence suitable to carry out the adjustment at 0 % and at 100 %.

Linearisation point 2 is at a filling level of 40 %. At this filling level there are 250 litres in the vessel. Linearisation point 3 is at a filling level of 80 %, where 1000 litres are in the vessel. Linearisation point 4 is at a filling level of 100 % (level distance 0,500 m), where 1200 litres are in the vessel.

- with signal conditioning instrument

- or with the small, detachable adjustment module MINICOM.

All adjustment options are available for the adjustment with signal conditioning instru- ment VEGAMET like with PC. The adjustment just differs in the demonstration however not in the function.

With the adjustment module MINICOM all sensor relevant adjustments (adjustment, meas. range, meas. conditionins, sensorindication-scaling or false echo memory) are available. However not possible are the adjustment steps relating to the configuration of the signal conditioning instrument VEGAMET or the processing system VEGALOG and their signal processing (configuraton of inputs and outputs, linearisation curves, simulation…).

The adjustment of VEGAMET and MINICOM is identical. They are adjusted with 6 keys. A small display shows you beside the measured value, in short words a message on the menu point or on a figure of a menu adjustment. The information quantity of the small display however cannot be compared with the adjustment program VVO, however in conjunction with the following menu plan of MINICOM and VEGAMET 515 V you will have no problems with the adjustment. Some users however will find the work with the small adjustment field quicker and more direct to make than with the PC. The menu plan to VEGAMET 514 V is provided in the operating instruction of VEGAMET 514 V.

Set-up - Adjustment with VEGAMET or MINICOM

Following short explanations to the set-up steps 1 … 9.

1. Configuration of the input

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

2.) Operating range

Without special adjustment, the operating range corresponds to the meas. range. The meas. range has already been adjusted with the min./max. adjustment. Generally it is useful to choose the operating range slightly bigger (approx. 5 %) than the meas. range. Example: Min./max. adjustment: 0,500 … 3,400 m; adjust operating range to approx. 0,400 … 3,500 m.

68 dB – 53 dB = 15 dB

With 15 dB signal distance there is a high reliability.

7.) False echo storage

A false echo storage is always useful when false echo sources such as e.g. struts must be reduced. With the creation of a false echo storage you cause the sensor electronics to note the false echoes and to save them in an internal database. The sensor electronics treats these (false) echoes differently than the useful echo and gates them out.

9. Conditioning / Scaling of the sensor display

The menu point "Conditioning" in the MINICOM-menu only relates to the SENSOR-display and will be overwritten by the adjustments in the signal condi tioning instrument.

6.4 Adjustment with PC on VEGALOG

For connection of the PC to the processing system VEGALOG you require a standard interface RS232 DTE-DTE (Data Terminal Equipment) interface cable. With this cable you connect the PC with the processing system.

Via the signal and supply lines between sensor and processing system also adjustment signals are transmitted digitally beside the measured values. The adjustment program VVO can then communicate with the processing system and all connected sensors. In chapter "2.2 Configuration of measuring systems" the connection of the PC to the various meas. systems is shown.

Set-up - Adjustment with PC on VEGALOG

The first set-up steps with the PC in conjunction with the processing system VEGALOG correspond to the adjustment in chapter "

Adjustment with VEGAMET or MINICOM

6.2

• Connect the standard output of your PC with the standard RS232-interlink cable (9pole) with the processing system VEGALOG.

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

After approx. 1…2 minutes (selfcheck) the meas. system consisting out of processing system and sensors is normally ready for operation and the sensors indicate measured values.

• Now start the adjustment software VVO on your PC.

Before starting with the set-up:

The many pictures, adjustment steps and menus may be confusing but just carry out the set-up with the PC step-by-step and you will soon no more require the following pages.

When you want to enter or enquire something this is marked in the following with a dot, e.g.

• Choose …

• Start …

• Click to …

72 VEGASON 51 V … 53 V

• Choose in the initial screen with the arrow keys or the mouse the point "

Planning

" and

click to "OK".

In the next window you are asked for the identification.

Set-up - Adjustment with PC on VEGALOG

When you connect VVO to a VEGALOG where data have been already saved, a message is displayed whether you want to transfer the saved data from the PC to VEGALOG or whether the data of VEGALOG should be transferred to the PC.

• Enter under name "

• Also enter under password

VEGA

The adjustment program, called in the following VVO, contacts the connected Meas. system/sensor …… and shows after a few seconds if and with which Meas. system/ Sensors a connection exists.

Note:

If you do not get a sensor connection, check the following:

- is the processing system powered with supply voltage?

- do you erroneously use a wrong RS232cable instead of the VEGA RS-232-connection cable?

If VVO (adjustment software) contacts the processing system for the first time, you are asked if the data should be transferred from the processing system to the PC.

• Click to "

Yes

• Click to "OK", and you are in the main menu window.

The preadjusted identification can be modified later in the menu "

Configuration

The adjustment of an ultrasonic sensor on a VEGALOG with the PC generally correponds to the adjustment of an ultrasonic sensor on the signal conditioning instrument, like in chapter "

VEGAMET

The difference is just in the higher configuration requirement of VEGALOG. A number of possible sensor inputs and signal outputs as well as various processing routines must be coordinated. First of all it must be defined which sensor (input) should be processed where and how.
