1 . Measuring principle
UltrasoniclevelmeterULM® is a compact measuring device consisting of two parts - main level me-ter(thebodywithmeasuringelectronics)anddisplaymodule.Usingtheelectroacousticconverter,the level meters transmit the sequence of ultrasonic pulses that spread towards the surface level. Theconverterrecuperatesreflectedacousticwavesthataresubsequentlyprocessedintheelec-tronicmodule.Theintelligentevaluationblockfiltersoutinterferingsignals,comparesthecleanedreceivedsignalwith the false reflectionmap (e.g. frommixers, ladders, reinforcementetc.)andselectsasuitablereflection(echo).Basedontheperiodduringwhichtheindividualpulsesspreadtowardsthesurfacelevelandbackandbasedonthemeasuredtemperatureinthetank,theinstantdistancetothesurfaceleveliscalculated.Accordingtothelevelheight,thelevelmeteroutputissetandthemeasuredvalueisdisplayedonthedisplay.
2 . range of applicaTions
Forcontinuousnon-contactlevelmeasurementofliquids(watersolutions,seweragewater,etc.),mashandpastematerials(sediments,sticks,resinsetc.)inclosedoropenvessels,sumps,reser-voirsandopenchannels.Incasethelevelofbulk-solidmaterialsismeasured,themeasurementrange is reduced.The levelmeterscancontinuouslymeasure levelsofbulk-solidmaterialswitha low concentration of dust particles. Consult the manufacturer on recommended use of the level meterforbulk-solidmaterials.
3 . VarianTs of sensors
All operations described in this instruction manual have to be carried out only by trained personnel or an accredited person. Warranty and post warranty service must be exclusively carried out by the manufacturer.
Improper use, installation or set-up of the level meter can result in crashes in the application (overfilling of the tank or damage of system components).
The manufacturer is not responsible for improper use, losses of work caused by either direct or indirect damage, and for expenses incurred during installation or use of the level meter.

• Incasethelevelofbulksolidsismeasured,themeasurementrangeisreducedDuetoabsorp-tionofacousticwavesbyabulkmedium,short-eningofthemeasuringrangeoccursbyupto50% depending on the grain size. We therefore recommend selecting a level meter with greater range than the maximum range of measuring the medium. It is also appropriate to use a di-rectionalhorn(seeimage8),whichreducestheshorteningofthemeasuringrange,becauseitbetterconcentratesacousticenergywhilepre-serving the same beam angle, and improvesthe sensitivity when receiving the reflectedecho. We recommend to consult the use with the manufacturer.

• Scattering or attenuation of theultrasonic signal can result if the surfacelevelhasbeenmoderate-ly stirred or rippled (byamixer,coming liquid etc.). It can resultin reduction of the measurement rangeorunreliablefunctionofthelevelmeter(Fig.10).
• Rotatingmixer blades can cause thatthesurfaceisstirred,whichre-sultsinfalsereflectionsoftheultra-sonic signal from the surface level and unreliable operation of thelevelmeter(Fig.13).(obr.11).For a rippled or swirling level, you can use the directional horn to elimi-nate scattering of the ultrasonic signal.
• During filling, mixing and other processes, foam can arise on the surface level of the measured liq-uid. The foam considerably absorbs the ultrasonic sig-nal which might cause malfunction of the level meter (Fig.9).Forsuchcases, it isnecessary tosetup"SENSI-TIVITY"modeto"high"orcontactthemanufacturerifneed.

Electrical connection must be done in de-energized state!
With regard to possible occurrence of electrostatic charge on non-conductive parts of the level meter, all level meters for explosive spaces (ULM–70Xi type) must be grounded. It will be done using a screw placed on the head of the level meter under the cable outlet.

The supply voltage source should be preferably realized as a stabilized power supply unit with safe voltage from 18 to 36 V DC (18 ÷ 30 V DC for Xi version), which can be a part of the evaluation or display device.
In case of strong electromagnetic interferences (EMI), parallel cable ducting with power lines, or when cable length exceeds 30 m we recommended to use shielded cable.
It is also necessary to design and take measures to reduce the effects of static electricity to a safe level in the wiring.
Installation in explosive atmospheres needs to be carried out in compliance with CSN EN 60079-14 (Electrical installations for explosive gaseous atmospheres – Part 14: Electrical installations in dangerous areas other than mining) and possibly also in compliance with other standards relating to the area concerned.

"LOW" – Low sensitivity in case of surrounding interferences affecting the measurement. "MEDIUM" – Medium sensitivity (suitable for most applications)."HIGH" – Enhanced sensitivity for measured mediums partly absorbing the ultrasonic signal (bulk solids, foams)

If during the scanning of the tank in the bottom of the display appears the dialog "press OK to stop" (see figure) the level meter already found no further obstacles and "TEACHING" mode may be terminated. If it is not terminated, the level meter is still ready for the possible presence of obstacles (e.g. paddles of the agitator). Once it registers a further obstacle, the dialogue disappears and the obstacle is erased. This process may be repeated up to 1000 cycles. After this the "TEACHING" mode is automatically stopped.

MEDIUM TEMPERATURE
The level meter is equipped with automatic temperature compensation. If for instance in the tank there is a difference of 10°Cbetween the temperature of themeasuredmaterial (me-dium) and the temperature at themounting site of the levelmeter (see themode "DIAGNOS-TICS, page 20), the measuring accuracy will be reduced by around 1% of the set range. Ifthis function is activated, this temperature difference can be compensated. If in the tank (openchannel) isabigdifferencebetweenthetemperatureof themeasuredmedium(liquid)andtem-perature in theplaceof installationof theULM(seemode, "DIAGNOSTICS"page20), it isad-vised to improve the precision of the measurement by the zone temperature compensation.
