3.2 Principle of operation

The VEGAPULS 62 radar sensor can be used in a wide variety of ap-plications for continuous level measurement of liquids. It is suitable for

applications in storage vessels, reactors and process vessels, evenunder extremely dicult process conditions.

Dependent on the application range, dierent versions are used:

• Antenna – Small tanks and process vessels, measurement of virtually all

products: Horn antenna ø 40 mm – Storage tanks and process vessels, measurement of products

such as solvents, hydrocarbons and fuels under extremely dif-cult process conditions: Horn antenna ø 48 … 95 mm

– Products with low εr value with large measuring distances:

Parabolic antenna

• Electronics – Products with an ε

r value ≥1.8: Standard electronics

– Products with an εr value < 1.8, ≥1.5; applications with very bad

reective properties: Electronics with increased sensitivity

The actual values that can be reached depend on the measurementconditions, the antenna system or the standpipe or bypass.

The antenna of the radar sensor emits short radar pulses with aduration of approx. 1 ns. These pulses are reected by the productand received by the antenna as echoes. The transit time of the radar

pulses from emission to reception is proportional to the distance andhence to the level. The determined level is converted into an appropri-ate output signal and outputted as measured value.

4.1 General instructions

With instruments with threaded process tting, suitable tools must be

applied for tightening the hexagon.Warning:The housing must not be used to screw the instrument in! Applyingtightening force can damage internal parts of the housing.

Use the recommended cables (see chapter "Connecting to powersupply ") and tighten the cable gland.

You can give your instrument additional protection against moisturepenetration by leading the connection cable downward in front of thecable entry. Rain and condensation water can thus drain o. This ap-

plies mainly to outdoor mounting as well as installation in areas wherehigh humidity is expected (e.g. through cleaning processes) or oncooled or heated vessels.

Make sure that all parts of the instrument exposed to the process, inparticular the active measuring component, process seal and processtting, are suitable for the existing process conditions. These includeabove all the process pressure, process temperature as well as thechemical properties of the medium.

You can nd the specications in chapter "Technical data" and on thetype label.

4.2 Mounting preparations - Horn antenna

The instrument is also available in versions with an antenna whosediameter is larger than the process tting (thread, ange). In suchcases the antenna must be disconnected from the process ttingbefore mounting. Proceed as follows:

1. Loosen the hexagon socket screws (3) on the antenna socketwith an Allen wrench (size 3)

2. Remove the antenna (4)

Note:The plastic cone may not be pulled out of the antenna socket.

3. Insert the antenna from below into the vessel socket and secure itagainst falling o

4. Retighten the antenna with hexagon screws to the antennasocket; torque max. 2.5 Nm (1.8 lbf ft)

Note:The radar sensor with rinsing air connection or antenna extensionis provided with a notch on the antenna socket. This notch must bealigned with the marking on the process tting (the marking species

the position of the polarisation plane of the radar signal).

4.4 Instructions for installation

The illustrations with the following mounting instructions show a radarsensor with horn antenna. The mounting instructions apply analo-gously also to the version with parabolic antenna.

The emitted radar impulses of the radar sensor are electromagneticwaves. The polarisation plane is the direction of the electrical wave

component. By turning the instrument in the connection ange ormounting boss, the polarisation can be used to reduce the eects offalse echoes.

The position of the polarisation plane is marked on the process ttingof the instrument.

When mounting the sensor, keep a distance of at least 200 mm(7.874 in) from the vessel wall. If the sensor is installed in the centerof dished or round vessel tops, multiple echoes can arise. However,

these can be suppressed by an appropriate adjustment (see chapter"Setup").

If you cannot keep this distance you should carry out a false echostorage before setup. This applies mainly if buildup on the vessel wall

In vessels with conical bottom it can be advantageous to mount thesensor in the center of the vessel, as measurement is then possibledown to the lowest point of the vessel bottom.

Tip:

The instrument is also optionally available with an antenna extension.The antenna length can be selected (either ex works or later) to allowthe antenna to protrude slightly out of the end of the mounting socket.Due to the antenna extension however, disturbing reections aregenerated in the close-up range. This can lead to an increase in therequired minimum distance, especially with poorly reecting mediasuch as plastic powder. In practice, a cleanly constructed mountingsocket, if necessary with rounded edges, introduces fewer disturbinginuences than an antenna extension.

Align the sensor in liquids as vertical as possible to the product sur-face to achieve optimum measurement.

Fig. 16: Alignment in liquids

The mounting location of the radar sensor should be a place where noother equipment or xtures cross the path of the microwave signals.

Vessel installations, such as e.g. ladders, limit switches, heating spi-rals, struts, etc., can cause false echoes and impair the useful echo.Make sure when planning your measuring site that the radar sensorhas a "clear view" to the measured product.

In case of existing vessel installations, a false echo storage should be

carried out during setup.If large vessel installations such as struts or supports cause falseechoes, these can be attenuated through supplementary measures.

Small, inclined sheet metal baes above the installations scatter theradar signals and prevent direct interfering reections.

Fig. 17: Cover smooth proles with deectors

If there are agitators in the vessel, a false signal suppression shouldbe carried out with the agitators in motion. This ensures that theinterfering reections from the agitators are saved with the blades indierent positions.

Fig. 18: Agitators

Through the action of lling, stirring and other processes in the vessel,compact foams that considerably damp the emitted signals may formon the product surface.

If foams are causing measurement errors, the biggest possible radarantennas, the electronics with increased sensitivity or low frequencyradar sensors (C band) should be used.

As an alternative, sensors with guided microwave can be used. Theseare unaected by foam generation and are best suited for such ap-plications.

When using a surge pipe in a vessel, inuences from vessel installa-tions and turbulences can be excluded. Under these prerequisites,the measurement of products with low dielectric values (ε

r value

≥ 1.6) is possible. In very adhesive products, measurement in a surgepipe is not recommended.

Constructional requirements on the surge pipe:

• Material metal, smoother inner tube• Preferably pultruded or straight beaded stainless steel tube• Welded joint should be straight and lie in one axis with the holes• Flanges are welded to the tube according to the orientation of the

polarisation level• In case of a extension with a welding neck ange or pipe collar

as well as when a ball valve is used, the inner surfaces should bealigned and accurately joined together

• Gap size with junctions ≤ 0.1 mm• Do not weld through the pipe wall. The surge pipe must remain

smooth inside. Roughness and beads on the inside caused byunintentional penetration should be removed since they causestrong false echoes and encourage buildup

• Surge pipes must extend all the way down to the requested min.level, as measurement is only possible within the tube

• Diameter of holes ≤ 5 mm, any number OK, on one side or com-pletely through• The antenna diameter of the sensor should correspond to the

inner diameter of the tube

• Diameter should be constant over the complete length

An alternative to measurement in a surge pipe is measurement in abypass tube outside of the vessel.

5.1 Preparing the connection

Always keep in mind the following safety instructions:

• Connect only in the complete absence of line voltage• If overvoltage surges are expected, overvoltage arresters shouldbe installed

Power supply and current signal are carried on the same two-wirecable. The voltage supply range can dier depending on the instru-ment version.

The data for power supply are specied in chapter "Technical data".

Provide a reliable separation between the supply circuit and themains circuits according to DIN VDE 0106 part 101.

Keep in mind the following additional factors that inuence the operat-ing voltage:

• Output voltage of the power supply unit can be lower under nomi-nal load (with a sensor current of 20.5 mA or 22 mA in case of faultmessage)

• Inuence of additional instruments in the circuit (see load values inchapter "Technical data")

The instrument is connected with standard two-wire cable withoutscreen. If electromagnetic interference is expected which is above the

test values of EN 61326-1 for industrial areas, screened cable shouldbe used.

For instruments with housing and cable gland, use cable with roundcross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)ensures the seal eect of the cable gland. If you are using cable witha dierent diameter, exchange the seal or use a suitable cable gland.

We generally recommend the use of screened cable for HART multi-drop mode.

With plastic housing, the NPT cable gland or the Conduit steel tube

must be screwed without grease into the threaded insert.Max. torque for all housings see chapter "Technical data"

If screened cable is necessary, connect the cable screen on bothends to ground potential. In the sensor, the screen must be connecteddirectly to the internal ground terminal. The ground terminal on theoutside of the housing must be connected to the potential equalisa-tion (low impedance).

If potential equalisation currents are expected, the connection on theprocessing side must be made via a ceramic capacitor (e. g. 1 nF,1500 V). The low frequency potential equalisation currents are thussuppressed, but the protective eect against high frequency interfer-ence signals remains.

Warning:Signicant potential dierences exist inside galvanization plants aswell as on vessels with cathodic corrosion protection. Considerableequalisation currents can ow over the cable screen if the screen isgrounded on both ends.

To avoid this in such applications, the cable screen must be connect-ed to ground potential only at one end (in the switching cabinet). Thecable screen must not be connected to the internal ground terminal inthe sensor and the outer ground terminal on the housing must not beconnected to the potential equalisation!

Information:The metal parts of the instrument (process tting, transmitter, concen-tric tube, etc.) are conductively connected with the inner and outerground terminal on the housing. This connection exists either directlyvia connecting metallic parts or, in case of instruments with external

electronics, via the screen of the special connection cable.You can nd specications on the potential connections inside theinstrument in chapter "Technical data".

5.2 Connecting

The voltage supply and signal output are connected via the spring-loaded terminals in the housing.

The connection to the indicating and adjustment module or to theinterface adapter is carried out via contact pins in the housing.

Information:The terminal block is pluggable and can be removed from the elec-tronics. To do this, lift the terminal block with a small screwdriver andpull it out. When inserting the terminal block again, you should hear itsnap in.

Proceed as follows:

1. Unscrew the housing cover

2. If an indicating and adjustment module is installed, remove it byturning it slightly to the left.

3. Loosen compression nut of the cable entry4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.

1 cm (0.4 in) of insulation from the ends of the individual wires

5. Insert the cable into the sensor through the cable entry

You can nd in the operating instructions manual "Indicating and adjustment module" also the description of the menu sections "Display "and "Info".

In the main menu point "Setup", the individual submenu points shouldbe selected subsequently and provided with the correct parameters

to ensure the optimum adjustment of the measurement. The proce-dure is described in the following.

Each medium has dierent reection properties. With liquids, furtherinterfering factors are uctuation product surface and foam genera-tion. With bulk solids, these are dust generation, material cone andadditional echoes from the vessel wall.

To adapt the sensor to these dierent measuring conditions, theselection "Liquid " or "Bulk solid " should be made in this menu item.

Through this selection, the sensor is adapted perfectly to the productand measurement reliability, particularly in products with poor reec-tive properties, is considerably increased.

Enter the requested parameters via the appropriate keys, save yoursettings with [OK] and jump to the next menu item with the [ESC] andthe [->] key.

In addition to the medium, also the application, i.e. the measuring site,can inuence the measurement.

With this menu item, the sensor can be adapted to the applications.The adjustment possibilities depend on the selection "Liquid " or "Bulksolid " under "Medium".

The following options are available when "Liquid " is selected:

The "Echo curve" shows the signal strength of the echoes over themeasuring range in dB. The signal strength enables an evaluation ofthe quality of the measurement.

The "False signal suppression" displays the saved false echoes (seemenu " Additional settings") of the empty vessel with signal strength in"dB" over the measuring range.

A comparison of echo curve and false signal suppression allows amore accurate conclusion on measurement reliability. The selected

curve is continuously updated. With the [OK] key, a submenu withzoom functions is opened:

• "X-Zoom": Zoom function for the meas. distance• "Y-Zoom": 1, 2, 5 and 10x signal magnication in "dB"• "Unzoom": Reset the presentation to the nominal measuring range

with single magnication

With the function "Echo curve memory " the echo curve can be savedat the time of setup. This is generally recommended; for using the As-set Management functions it is absolutely necessary. If possible, the

curve should be saved with a low level in the vessel.With the adjustment software PACTware and the PC, the high resolu-tion echo curve can be displayed and used to recognize signalchanges over the operating time. In addition, the echo curve of thesetup can be also displayed in the echo curve window and comparedwith the actual echo curve.

• Vessel installations such as struts• Agitators• Buildup or welded joints on vessel walls

Note:

A false signal suppression detects, marks and saves these false sig-nals so that they are no longer taken into account for level measure-ment.

This should be done with the low level so that all potential interferingreections can be detected.

Proceed as follows:

1. Select the menu item " Additional settins" with [->] and conrmwith [OK] . With [->] you have to select the menu item "Falsesignal suppression" and conrm with [OK] .

2. Conrm again with [OK] .

3. Conrm again with [OK] .

4. Conrm again with [OK] and enter the actual distance from thesensor to the product surface.

5. All interfering signals in this section are detected by the sensorand stored after conrming with [OK] .

Note:

Check the distance to the product surface, because if an incorrect(too large) value is entered, the existing level will be saved as falsesignal. The lling level would then no longer be detectable in this area.

If a false signal suppression has already been created in the sensor,the following menu window appears when selecting "False signalsuppression":

The menu item "Delete" is used to completely delete an already cre-ated false signal suppression. This is useful if the saved false signalsuppression no longer matches the metrological conditions in thevessel.

The menu item "Extend " is used to extend an already created false

signal suppression. This is useful if a false signal suppression wascarried out with a too high level and not all false signals could be de-tected. When selecting "Extend ", the distance to the product surfaceof the created false signal suppression is displayed. This value cannow be changed and the false signal suppression can be extended tothis range.

A linearization is necessary for all vessels in which the vessel volumedoes not increase linearly with the level - e.g. in a horizontal cylindri-cal or spherical tank - and the indication or output of the volume isrequired. Corresponding linearization curves are preprogrammed

for these vessels. They represent the correlation between the levelpercentage and vessel volume.

By activating the appropriate curve, the volume percentage of thevessel is displayed correctly. If the volume should not be displayed inpercent but e.g. in l or kg, a scaling can be also set in the menu item"Display ".

Enter the requested parameters via the appropriate keys, save yoursettings and jump to the next menu item with the [ESC] and [->] key.

Caution:Note the following if the instrument with corresponding approval isused as part of an overll protection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longerlinearly proportional to the level. This must be taken into considerationby the user, particularly when setting the switching point on the levelswitch.

With a reset, certain parameter adjustments carried out by the userare reset.

The following reset functions are available:

Delivery status: Restoring the parameter settings at the time of ship-ment from the factory incl. the order-specic settings. A created false

6.4 Saving the parameter adjustment data

We recommended noting the adjusted data, e.g. in this operatinginstructions manual, and archiving them afterwards. They are thusavailable for multiple use or service purposes.

If the instrument is equipped with an indicating and adjustmentmodule, the data in the sensor can be saved in the indicating andadjustment module. The procedure is described in the operatinginstructions manual "Indicating and adjustment module" in the menuitem "Copy sensor data". The data remain there permanently even ifthe sensor power supply fails.

The following data or settings for adjustment of the indicating andadjustment module are saved:

• All data of the menu "Setup" and "Display "• In the menu " Additional adjustments" the items "Sensor-specic

units, temperature unit and linearization"

• The values of the user programmable linearisation curveThe function can also be used to transfer settings from one instru-ment to another instrument of the same type. If it is necessary toexchange a sensor, the indicating and adjustment module is insertedinto the replacement instrument and the data are likewise written intothe sensor via the menu item "Copy sensor data".
