1. Overview of measuring principles

RadarMicropilot works with high-frequencyradar pulses which are emitted byan antenna and reflected from the

product surface. The time of flight ofthe reflected radar pulse is directlyproportional to the dist ance traveled. Ifthe tank geometry is known, the levelcan be calculated from this variable.

Micropilot MNon-contact, maintenance-freemeasurement also under extremeconditions. Unaffected by density,

temperature, conductibility andhumidity. No impairment by vaporpressure.

Process temperatures up to+400°C/+752°FProcess pressures up to160bar/2320psi

Guided radarLevelflex works with high-frequencyradar pulses which are guided alonga probe. As the pulse impacts themedium surface, the characteristicimpedance changes and part of theemitted pulse is reflected. The timebetween pulse launching and receivingis measured and analyzed by theinstrument and constitutes a directmeasure for the distance between theprocess connection and the product

surface.

LevelflexReliable and maintenance-freemeasurement in liquids, also inturbulent media and foam. Unaffectedby density, temperature, conductibil ityand humidity. No impairment by vaporpressure. Measurement of interfaceand level.

Process temperatures up to+450°C/+842°FProcess pressures up to

400bar/5,800psi

UltrasonicsUltrasonic measurement is based onthe time-of-flight principle. A sensoremits ultrasonic pulses, the surface ofthe media reflects the signal and thesensor detects it again.The time of flight of the reflected

ultrasonic signal is directly proportionalto the distance traveled. With theknown tank geometry the level can becalculated.

Prosonic S/M/TNon-contact and maintenance-freemeasurement without impairment byproduct properties, e.g. dielectricconstant, conductivity, density orhumidity.

Process temperatures up to+150°C/+302°FProcess pressures up to3bar/44psi

Hydrostatics (differential pressure)In closed, pressurized tanks, thehydrostatic pressure of the liquidcolumn causes a difference in pressure.The same leads to a deflect ion ofthe measuring element which isproportional to the hydrostaticpressure.

Deltabar SUnaffected by dielectric constant,foam, turbulence and obstacles.High overload resistance.

Process temperatures up to+400°C/+752°FProcess pressures up to420bar/6,090psi

CapacitanceThe principle of capacitive level

measurement is based on the capacitancechange of a capacitor. The probeand the tank wall form a capacitor

whose capacitance is dependent onthe amount of product in the tank: anempty tank has a lower, a filled tank ahigher capacitance.

Liquicap M/TExact measurement from the end of

the probe to the process connect ion without any blocking distance. Veryfast response times. Unaffected bydensity, turbulence and vapor pressure.

Process temperatures up to+200°C/+392°FProcess pressures up to100bar/1,450psi

Hydrostatics (pressure)Hydrostatic level measurement in opentanks is based on the determinationof the hydrostatic pressure which is

generated by the height of the liquidcolumn. The obtained pressure is thusa direct measure for the level.

Cerabar S/M, Deltapilot S/MUnaffected by dielectric constant,foam, turbulence and obstacles.Condensate-proof, watertight and

long-term stable Contite measuringcell with optimized temperature shockbehavior (Deltapilot S).

Process temperatures up to+400°C/+752°F

Radiometry The gamma source, a cesium or cobalt

isotope, emits radiation which isattenuated as it passes through materials.The measuring effect results from theabsorpt ion of radiation by the productto be measured which is caused bylevel changes.The measuring system consists of asource and a compact transmitter as areceiver.

Gammapilot MNon-contact measurement from outside

for all extreme applications, e.g. verycorrosive, aggressive and abrasivemedia.

Unaffected by media Any process temperature Any process pressu reUnaffected by gammagraphy

Dielectric constant (DK)The reflection properties of a mediumare determined by the dielectricconstant (DK).The following table shows the allocationof dif ferent DK values to media groups.If the dielectric constant of a mediumis not known, we recommend to usea DK value of 1.9 for sizing in order to

maintain a safe measurement.

! For reliable measurement:Use a horn antenna whenever possible. In addition,this should have the largest possible diameter.

4. Instrument selection within the measuring principle

Weather protection cover Always recommended for outside insta llat ion to avoid st rongtemperature changes of electronics

InstallationNot in the centerNot above the fillstreamDistance to wall: ~ 1/6 of the tank diameter, at least, however,30cm/12" (6GHz), or 15cm/6" (26GHz)

If these conditions cannot be met: Use stilling wellLateral installation on request

NozzleFMR230/240 horn antenna should prot rude from the nozzle. Pleasenote the max. nozzle length, otherwise use antenna extension

FMR244/245 note the max. nozzle lengthThe inactive part of the rod antenna should be longer than the heightof the nozzle. Please contact our application consultant if this i s notpossiblePlease note the information in the Technical Documentations

Measuring rangeMeasurement is possible up to the t ip of the antenna, on principle,however, the end of the measuring range should not be closer than50mm/2" to the tip of the antenna because of corrosion and build-upformationThe measuring range starts where the radar beam meets the tankbottom. With dish bottoms or conical outlets, the level cannot bedetected below this point

Tank installations Avoid any installations li ke limit switches, temperature sensors, etc. within the signal beam (see table below)Symmetrical installations, e.g. vacuum rings, heating coils, flowbreakers, etc. may impair measurement

Optimization optionsSize of antenna: The larger the antenna diameter the smaller thebeam angle (see table below, the less interference echoes)

A sti ll ing wel l or a Levelflex M can a lways be used to avoidinterference

Foam of formationRadar pulses may be absorbed by foamThe surface of foam can ref lect. Solution: Trial measurement with26GHz or e.g. Levelflex or hydrostatic measurement

Blocking distance top*:- Coax probe: 0mm/0"

Rope or rod probe >8m/26ft: 0.025 x probe length

Minimal distance from tank bottom: >10mm/0.4"

* The blocking dista nce (BD) is preset from the factory.Depending from the application these settings can beadjusted.

If the DK value in rope probes is < 7, measurement is not possible in thetensioning weight area (0…250mm/10" from t he end of the probe - lowerblocking distance). Less accurate measurement is possible in the lower areaof the probe.

Closed tanks with FMD78

(capillary diaphragm seal)Level measurement is only safeguarded betweenthe upper edge of the lower and the lower edge ofthe upper diaphragm sealIn vacuum applications, it is recommended toinstall the pressure transmitter below the lowerdiaphragm seal. This will avoid a vacuum load ofthe diaphragm seal caused by the presence of fillingoil in the capillaries

Optimizing measuresIn order to avoid additional pressure fluctuationsand a defective instrument, the capillaries should

be installed free of vibrationsThe capillaries may not be installed in the vicinityof heating or cooling pipes which would impairexact measuring resultsIt is recommended to insulate the capil laries in acolder or warmer environment In case of two-sided diaphragm seal systems, theambient temperature and the length of bothcapillaries should be identicalTwo identical diaphragm seals (e.g. d iameter,material, etc.) should always be used for the minusand plus side

Installation of the pressure transmitter abovethe lower diaphragm seal

If the pressure transmitter is installed above thelower diaphragm seal, the maximum height (seeTechnical Informat ion) may not be exceededThe maximum difference in height depends on thedensity of the filling oil and the lowest pressure

A Electromechanical level system

A weight is lowered on a measuringtape. As it meets the surface of the bulksolids, the tensi le force of the weight

is reduced. This change is recognized,the inst rument reverses the sense ofrotation of the motor and rewinds thetape. A pulse generator counts therotations in a non-contact manner asthe weight is lowered. Each countedpulse corresponds to an exactly defineddistance. If this distance is deductedfrom the overall dist ance (height of the

vessel), the level results.

Silopilot M/TRobust system for safe measurementsalso in extremely dusty environmentsand low density media. Unaffected by

product properties and DK value.

Radiometry The gamma source, a cesium orcobalt isotope, emits radiation whichis attenuated as it passes throughmaterials. The measuring effect resultsfrom the absorption of radiation by theproduct as the level changes.The measuring system consists of asource and a compact transmitter as a

receiver.

Gammapilot MCompact transmitter in differentmeasuring lengths, adaptable to themeasuring range.Non-contact measurement fromoutside, for all extreme applications,e.g. very abrasive, corrosive andaggressive media:Typical applications: Level measurement

in pulp digesters, wood chip silos andfluidized bed reactors or in density andmass flow measurement.

Unaffected by media Any process temperature Any process pressu reUnaffected by gammagraphy(FHG65)

Installation instructions – radar

InstallationNot centered [3]Not above filling curtain [4]Distance to the wall [1]: ~ 1/6 of vessel diameter, at least however20cm/7.9"

Weather protection cover [2] Always recommended for insta llat ion outside (solar rad iation andrain)

Connection for purge air or plating Connection for purge air:FMR250, already integrated. In case of strong dust generation,

clogging of the antenna is avoided. Not possible for FMR244Horn plating:FMR250, FMR240, see accessoriesFMR244, already integrated PP plating of the horn, avoids clogging

Baffles in vesselsMake sure that baf fles [1] like limit switches, struts, etc. arenot within the beam cone (see also the beam angle table in th isrespect (next page))Symmetrically arranged baffles [2], e.g. discharge aids etc. mayimpair measurements

Optimizing measures

Size of antenna: The larger the antenna the smaller the beam angleand the lower the interfering echoesInterference echo suppression: Electronic suppression of interferingechoes optimizes the measurement Inclined installed metallic plates [3] disperse the radar signals andreduce interfering echoes

Alignment Serves the avoidance of interfering ref lection and improvedmeasurement since the measurement can be aligned to the angleof repose

An a lignment of the instrument is recommendedFMR250, with optional alignment deviceFMR244, FMR240 with optional alignment seal or assemblebracket

Measurement in plastic vesselsIf the external wal l of the vessel consists of a non-conductive material (e.g. GFK), microwaves may alsobe reflected by external interfering sources, e.g.

Metal lines/pipesConductorsGrids

Ensure during installation that the beam cone ofthe radar inst rument for bulk solids is free of anyinterfering sources.

•••

4. Instrument selection within the measuring principle

Installation instructions – guided radar

Probe selection

Use rope probes for bulk solids in normal circumstances. Rod probes are only suited to short measuring rangesup to approx. 2m/6.5ft in bulk solids. This is part icularly true for applications in which the probe is installedlaterally and inclined and only for light and free-flowing bulk solidsIn case of large si los, the lateral load on the rope may be so high t hat a rope with a plast ic jacket must be used.

We recommend a PA-coated rope for milled products l ike cereal, wheat and f lour

Installation in concrete silosIn concrete silos, the largest possible distance [B] of the probe tothe concrete wall - min. 0.5m/19.7" - is to be observed.

The installation into a concrete ceiling must be flush with itsbottom edge

Expansion of rope probes by tension and temperature6mm/0.23" rope probe- Elongation by tension: At max. permissible tensile load (30kN)

= 13mm (0.5")/m rope length- Elongation by temperature increase from 30°C/86°F

to 150°C/302°F = 2mm (0.08")/m (ft) rope length4mm/0.16" rope probe- Elongation by tension: At max. permissible tensile load (12kN)

= 11mm (0.4")/m rope length- Elongation by temperature increase from 30°C/86°F

to 150°C/302°F = 2mm (0.08")/m rope length

InstallationDo not install rod and rope probes in the filling curtain [2]Insta ll rod and rope probes at a distance to the wall [B], so thatin case of build-up on the wal l a distance to the probe of at least100mm/4" remainsInstall rod and rope probes with the largest possible distance tobaff les. In case of distances < 300mm/12", an interference echosuppression must be included in commissioning

When rod and rope probes are insta lled in plast ic vessels, theminimum distance of 300mm/12" is also applicable to metallicparts outside of the vesselRod and rope probes may not contact metal vessel walls or bottoms.The minimum distance of the probe end to the bottom of the

vessel i s applicable [C]: > 10mm/0.4".For exceptions see the section “Fixation of rope probes”

Avoid bending the rope probe sharply dur ing insta llat ion oroperation (e.g. by product movements against the wall of the si lo)by the selection of a suitable point of instal lation

Weather protection cover [1] Always recommended for insta llat ion outside (solar rad iation andrain)

Fixation of rope probes

The fixat ion of the probe end may be required ifotherwise the probe contacts the silo wall, thecone, the baff les/struts or other parts at t imes orif the probe converges closer than 0.5m/19.7" toa concrete wall. The probe weight provides aninternal thread for this purpose:– 4mm/0.16" rope:

M 14– 6mm/0.23" rope:

M 20

Tensile loadBulk solids exert tensi le forces on rope probes. Theirintensity increases with:– The length of the probe or max. cover– The density of the product– The diameter of the silo and– The diameter of the probe ropeThe following diagrams show typical loads infrequently occurring bulk solids as reference values.The calculations take the following conditions intoaccount:– Freely suspended probe (end of probe not fixed)– Freely flowing bulk solids (mass flow).

The core flow cannot be calculated.In case of collapsing product accumulationon walls higher loads may occur

The tensile force values contain a safety factor of2 (compensation of the fluctuation range in freelyflowing bulk solids)Since the tensile forces largely depend on the flowproperties of the product, a higher safety factoris required for sluggishly flowing products andif a risk of product accumulation on walls exists.Use rather a 6mm/0.23" rope than 4mm/0.16" incritical casesThe same forces also act on the ceiling of silos. Thetensile forces are larger on fixed ropes, but theycannot be calculated. Please observe the tensile-loaded capacity of the probes or ensure that thiscapacity is not exceededIf the max. tensile load is exceeded, please verify

whether a non-contact ult rason ic or level radarinst rument should be used for the application

Please use preferably the 6mm/0.23" rope probe

because of its higher tensile-loaded capacity whenfixing a rope probeThe point of fixation must either be reliablygrounded or reliably insulated. If a fixation withreliable grounding is not possible, the insulated lugoffered as an accessory may be usedThe rope must be loose to avoid extremely hightensile loads and the risk of breakage. Adjust therope to a length which exceeds the requiredmeasuring range so that the rope slackens in the

NozzleThe sensor diaphragm should protrude from the nozzle. If this isnot possible, please compare the dimensions of the nozzle with thetable: Nozzle length (next page)

Measuring rangeMeasurement is possible up to the blocking distance (BD) on principleThe measuring range starts where the ultrasonic lobe meets thebottom of the silo. In dished or torispherical heads or conicaloutlets, levels below this point cannot be detected

Silo bafflesMake sure that baf fles [1] like limit switches, struts, etc. arenot within the beam cone (see also the beam angle table in th isrespect [ )Symmetrically arranged baffles [2], e.g. discharge aids etc. mayimpair measurements

Optimizing measuresUse a sensor with a smaller beam ang le. The smaller the beamangle the lower the occurrence of interfering echoesInterference echo suppression: Electronic suppression of interferingechoes optimizes the measurement Plates installed in an inclined manner [3] disperse the signal andcan avoid interfering echoes
