In hazardousareas you should take note of the appropriate regulations, conformity and type ap-proval certi?cates of the sensors and power supply units. The sensors must only beoperated on intrinsically safe circuits. The permissible electrical values are stated inthe certi?cate.30600-EN-0508161 Description of the measuring principleMeasuring principleShort ultrasonic pulses in the range of 35 kHz to 70 kHz are emitted by the transducerto the product surface, re?ected there and received by the transducer. The pulsestravel at the speed of sound - the elapsed time from emission to reception of thesignals depends on the level in the vessel.The latest microcomputer technology and the proven processing software select thelevel echo fromamonganynumberof falseechoesandcalculate theexact distance tothe product surface.An integrated temperature sensor detects the temperature in thevessel and compensates the in?uence of temperature on the signal running time.By simply entering the vessel dimensions, a level-proportional signal is generatedfrom the distance. It is not necessary to ?ll the vessel for adjustment.Wide application rangeOPTISOUND 3010 C, 3020 C and 3030 C ultrasonic sensors are especially suitablefor levelmeasurement of liquids, but are also good for solids.The instruments di?er inthe measuring range, the transducer version and the process ?tting. Through di?e-rent, adapted emitting frequencies, levels in a measuring range of 5 … 15 m(16.4 … 49.2 ft) can be measured. Resistant materialsfor transducers and process?ttings also allow applications in corrosive products (depending on the model). Apractical mounting strap (option) enables easy orientation of OPTISOUND 3030 C.Una?ected by product propertiesFluctuations in product composition or even complete product changes do not in?u-ence the measuring result. A fresh adjustment is not necessary.Service and maintenance friendlyThanks to thenon-contactmeasuring principle,OPTISOUND sensors are particularlyeasy to service and maintain.Description of the measuring principleUltrasonic – Level measurement in liquids 330600-EN-0508161.1 Application examplesOpen basinsFig. 1: Level measurement in an open basin withOPTISOUND 3010CA typical application forOPTISOUND 3010C sensors is level measurement on openbasins. Products such as rain water or sewage water, i.e. with impurities. Here iswhere the advantages of non-contact measurement with OPTISOUND come intotheir own: simple and maintenance-free. The degree of pollution of the water or anaccumulation of mud in the basin is not important, because OPTISOUNDmeasuresthe surface.Sludge containerFig. 2: Level measurement in a container with OPTISOUND 3030 CInsewage treatmentplants, theaccumulatedsludge is dewateredand transportedviaconveyor belts to containers.TheOPTISOUND 3030C sensormeasures the ?lling ofthe container. An empty container can thus be readied in good time before the max.level is reached. Thanks to the metal transducer diaphragm, measurement functio-nality is also ensured even under conditions of ?uctuating temperatures and steamgeneration.Description of the measuring principle4 Ultrasonic – Level measurement in liquids30600-EN-0508162 Type overviewOPTISOUND 3010 C OPTISOUND 3020 CApplications: liquids and solids in virtually allindustries, particularly in water andwaste water managementas OPTISOUND 3010 CMeasuring range: Liquids: 0.25 ... 5 m (0.8 ... 16.4 ft)Solids: 0.25 ... 2 m (0.8 ... 6.6 ft)Liquids: 0.4 ... 8 m (1.3 ... 26.2 ft)Solids: 0.4 ... 3.5 m (1.3 ... 11.5 ft)Process ?tting: G1½A of PVDF G2A of PVDFProcess temperature: -40 ... 80°C (-40 … +176°F) -40 ... 80°C (-40 … +176°F)Process pressure: -0.2 ... 2 bar (-20 ... 200 kPa) -0.2 ... 2 bar (-20 ... 200 kPa)(-2.9 ... 29 psi) (-2.9 ... 29 psi)Signal output two-wire/four-wire 4 … 20mA/HART two-wire/four-wire 4 … 20mA/HARTOPTISOUND 3030 CType overviewUltrasonic – Level measurement in liquids 530600-EN-050816OPTISOUND 3030 CApplications: liquidsandsolids in virtuallyall industriesMeasuring range: liquids: 0.6 ... 15m (2 ... 49.2 ft)solids: 0.6 ... 7 m (2 ... 23 ft)Process ?tting: compression ?angeDN 100 ormountingstrapProcess temperature: -40 ... 80°C (-40 … +176°F)Process pressure: -0.2 ... 1.0 bar (-20 ... 100 kPa)(-2.9 ... 14.5 psi)Signal output two-wire/four-wire 4 … 20mA/HARTType overview6 Ultrasonic – Level measurement in liquids30600-EN-050816Indicating andadjustment moduleHousingPlastic Stainless steel Aluminium Aluminium(double cham-ber)Electronics4 … 20mA/HART4 … 20mA/HART – four-wireSensorsTransducer1½'Transducer 2' Transducer 4'ApprovalsGas explosionprotectionType overviewUltrasonic – Level measurement in liquids 730600-EN-0508163 Mounting informationThe reference plane for the measurement is the lower edge of the transducer. Allstatements concerning themeasuring range as well as the internal signal processingrefer to this.With all instruments, a min. distance from the lower edge of the ?ange - the so-calleddead zone, in which measurement is not possible - must be maintained. The exactvalue of the dead zone, depending on the instrument version, is stated in the Techni-cal data.12Fig. 3: Min. distance to the max. level1 Dead zone2 Reference plane for the measurementNote:If the product reaches the transducer, buildup can form on it over a period of time andlater cause measurement errors.1 32100%0%Fig. 4: Measuring range and max. measuring distance1 full2 empty (max. measuring distance)3 max. measuring rangeGauge pressure in the vessel does not in?uence OPTISOUND. Low pressure orvacuum, however damp the ultrasonic pulses. This in?uences the measuring result,particularly if the level is very low. With pressures under -0,2 bar (-20 kPa) use adi?erent measuring principle, e.g. radar or guided radar (TDR).WhenmountingOPTISOUND, keepadistanceof at least200mmto the vessel wall. Ifthe sensor is installed in the center of dishedor spherical vessel tops,multiple echoescan arise. These can, however, be faded out by an appropriate adjustment.Mounting information8 Ultrasonic – Level measurement in liquidsMeasuring rangePressure/VacuumInstallation position30600-EN-050816If you cannot keep this distance, a false echo storage should be carried out duringsetup. This applies particularly if buildup on the vessel wall is expected. In this case,we recommend repeating the false echo storage later on with existing buildup.12> 200 mmFig. 5: Mounting on dished vessel tops1 Reference plane2 Vessel center or symmetry axisIn vessels with conical bottom it can be advantageous to mount the sensor in thecenter of the vessel, asmeasurement is then possible down to the lowest point of thevessel bottom.Fig. 6: Vessel with conical bottomThemounting socket should preferably be dimensioned to allow the lower edge of thetransducer to protrude at least 10mm out of the socket.Mounting informationUltrasonic – Level measurement in liquids 9Socket30600-EN-050816ca. 10 mmFig. 7: Recommended socket mountingIf the re?ective properties of the medium are good, you can mount OPTISOUND onsockets longer than the transducer.

By doing this, it is possible to ?ll thevessel nearly tomaximum.Suchanarrangement is suitable primarily for openvesselssuch as e.g. over?ow basins.~200~400x40045°Fig. 12: Beam de?ectorTheultrasonic sensor should be installed at a locationwhere no installations cross theultrasonic beam.Vessel installations such as, for example, ladders, limit switches, heating spirals,struts, etc. can cause false echoes superimposed on the wanted echo. Make surewhen planning your measuring location that the ultrasonic signals have 'free access'to the measured product.If there are existing vessel installations, a false echo storage should be carried outduring setup.Mounting informationUltrasonic – Level measurement in liquids 11Sensor orientationVessel installations30600-EN-050816If large vessel installations such as struts or supports cause false echoes, these canbe attenuated through supplementary measures.Small, inclined sheet metal or plas-tic ba?es above the installations scatter the ultrasonic signals and avoid direct falseechoes.Fig. 13: Cover smooth pro?les with de?ectorsThe instrumentsmust not bemounted inor above the?llingstream.Make sure that theproduct surface and not the in?owing material is detected.Fig. 14: In?owing liquidThrough the action of ?lling, stirring and other processes in the vessel, dense foamswhich considerably damp the emitted signals may form on the product surface.If foams are causing measurement errors, the sensor should be used in a standpipeor, alternatively, the more suitable sensors with guided radar (TDR) should be used.Guided radar is not in?uenced by foamgeneration and is particularly suitable for suchapplications.If there are strong air currents in the vessel, e.g. due to strong winds in outdoorinstallations, or because of air turbulence, you shouldmountOPTISOUND in a stand-pipe or use a di?erent measuring principle, e.g. radar or guided radar (TDR).By using a standpipe (surge or bypass tube), the in?uence of vessel installations,foam generation and turbulence is excluded.Mounting information12 Ultrasonic – Level measurement in liquidsIn?owing materialFoamAir ?owStandpipe measurement30600-EN-050816max.min.1Fig. 15: Standpipe in a tank1 Vent hole ø 5 … 10mmA standpipe measurement withOPTISOUND is possible with the following tube dia-meters:l OPTISOUND 3010 C from 40mml OPTISOUND 3020 C from 50mml OPTISOUND 3030 C from 100mm.Avoid large gaps and thick welding joints when connecting the tubes. A false echostorage should always be carried out.Measurement in a standpipe is not recommended for very adhesive products.Mounting informationUltrasonic – Level measurement in liquids 1330600-EN-0508164 Electrical connection4.1 General requirementsThe power supply range can di?er depending on the instrument version. The exactrange is stated in the Technical data.Take note of country-speci?c installation standards (e.g. the VDE regulations inGer-many) as well as prevailing safety regulations and accident prevention rules.In hazardous areas you should take note of the appropriate regulations, conformityand type approval certi?cates of the sensors and power supply units.4.2 Supply voltagePower supply andcurrent signal are carriedover thesame two-wire connectioncable.The requirements on the power supply are stated in theTechnical data of thisProductInformation manual.Power supply and current output are carried on two separate connection cables.The standard version can be operated with an earth-connected current output, theExd version must be operated with a ?oating output.The instrument is designed in protection class I. Tomaintain this protection class, it isabsolutely necessary that the ground conductor be connected to the internal groundconductor terminal.4.3 Connection cable and installationThe sensors are connected with standard cable without screen. An outer cable dia-meter of 5 … 9 mm ensures the seal e?ect of the cable entry.As an option, OPTISOUND are also available with standard plug connectors (seeTechnical data).If strongelectromagnetic interference is expected, screenedcable shouldbe used forthe signal lines.In Ex applications, the corresponding installation regulations must be noted for theconnection cable.4.4 Cable screening and groundingIf screened cable is required, the cable screen must be connected on both ends toground potential. If potential equalisation currents are expected, the connection onthe evaluation side must be made via a ceramic capacitor (e.g. 1 nF, 1500 V).Electrical connection14 Ultrasonic – Level measurement in liquids4… 20mA/HART two-wire4… 20mA/HART four-wire30600-EN-0508164.5 Wiring plansI2CDisplay11 2 5 6 7 8Fig. 16: Connection HART two-wire1 Power supply and signal outputI2C11 2Fig. 17: Connection HART two-wire1 Power supply and signal output4 ... 20 mAPE/ L/ NL1 N GND1 21 2 3 44...20mA ISFig. 18: Connection 4 … 20 mA/HART four-wire1 Supply voltage2 Signal outputElectrical connectionUltrasonic – Level measurement in liquids 15Single chamber housingDouble chamber hou-sing – two-wireDouble chamber hou-sing – 4 … 20 mA/HARTfour-wire30600-EN-050816Adjustment16 Ultrasonic – Level measurement in liquids5 Adjustment5.1 Adjustment, generalOPTISOUND can be adjusted with the following adjustment media:l the indicating and adjustment modulel a HART handheld (4 … 20mA/HART)The entered parameters are generally saved in OPTISOUND, optionally also in theindicating/adjustment module.5.2 Compatibility acc. to NAMUR NE 53OPTISOUND meet NAMUR recommendation NE 53.The parameter adjustment of the basic sensor functions is independent of the soft-ware version. The range of available functions depends on the respective softwareversion of the individual components.30600-EN-050816AdjustmentUltrasonic – Level measurement in liquids 175.3 Adjustment with the indicating/adjustment moduleThe indication and adjustment module can be plugged intoOPTISOUND sensors. Itcan be placed in four di?erent positions on the instrument (each displaced by 90°).Indication and adjustment are made via four keys and a clear, graphic-capable dotmatrix indication. The adjustment menu with language selection is clearly structuredand enables easy setup. After setup, the indicating/adjustment module serves asindicating instrument: through the screwed cover with glass insert, measured valuescan be read directly in the requested unit and presentation.1.1231Fig. 19: Indicating and adjustment elements1 LC display2 Indication of the menu item number3 Adjustment keysl [OK] key:- move to the menu overview- con?rm selected menu- edit parameter- save valuel [–>] key to select:- menu change- list entry- editing positionl [+] key:- modify value of a parameterl [ESC] key:- interrupt input- jump to the next higher menuSetup and indicationAdjustmentKey functions30600-EN-050816Technical data18 Ultrasonic – Level measurement in liquids6 Technical dataGeneral dataMaterials, wetted parts- Process ?tting PVDF- Transducer PVDF- Seal transducer/process ?tting EPDMMaterials, wetted parts- Mounting strap 1.4301- Process ?tting UP- transducer diaphragm 1.4571- Seal transducer/process ?tting EPDMMaterials, non-wetted parts- Compression ?ange (OPTISOUND3010 C)PPH, 1.4435- Housing plastic PBT (Polyester), Alu-die castingpowder-coated, 316L (stainless steel1.4435)- Seal ring between housing and hou-sing coverNBR (stainless steel housing), silicone(Alu/plastic housing)- Inspection window in housing coverfor indicating/adjustment modulePolycarbonate- Ground terminal stainless steel 1.4571/1.4435Weight- OPTISOUND 3010 C and 3020 C 1.8… 4.0 kg (4.0… 8.8 lbs), dependingon process ?tting and housing- OPTISOUND 3030 C 2.7 … 5.7 kg (6 … 12.6 lbs), dependingon process ?tting and housingOutput variableOutput signal 4 … 20mA/HARTResolution 1.6 µAFault signal current output unchanged;
