1 . Measuring principle
UltrasoniclevelmeterULM®isacompactmeasuringdeviceconsistingoftwoparts-mainlevelme-
ter(thebodywithmeasuringelectronics)anddisplaymodule.Usingtheelectroacousticconverter,
thelevelmeterstransmitthesequenceofultrasonicpulsesthatspreadtowardsthesurfacelevel.
Theconverterrecuperatesreectedacousticwavesthataresubsequentlyprocessedintheelec-
tronicmodule.Theintelligentevaluationblockltersoutinterferingsignals,comparesthecleaned
receivedsignalwiththefalsereectionmap(e.g.frommixers,ladders,reinforcementetc.)and
selectsasuitablereection(echo).Basedontheperiodduringwhichtheindividualpulsesspread
towardsthesurfacelevelandbackandbasedonthemeasuredtemperatureinthetank,theinstant
distancetothesurfaceleveliscalculated.Accordingtothelevelheight,thelevelmeteroutputisset
andthemeasuredvalueisdisplayedonthedisplay.
2 . range of applicaTions
Forcontinuousnon-contactlevelmeasurementofliquids(watersolutions,seweragewater,etc.),
mashandpastematerials(sediments,sticks,resinsetc.)inclosedoropenvessels,sumps,reser-
voirsandopenchannels.Incasethelevelofbulk-solidmaterialsismeasured,themeasurement
rangeisreduced.Thelevelmeterscancontinuouslymeasurelevelsofbulk-solidmaterialswith
alowconcentrationofdustparticles.Consultthemanufactureronrecommendeduseofthelevel
meterforbulk-solidmaterials.
3 . feaTures of varianTs
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
(overlling 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.

• Wheninstallinginanopen channel(reservoir,drain
etc.),installthelevelmeterontoabracketascloseas
possibletotheexpectedmax.level.
• Inconnectionwiththemeasurementprinciple,nosig-
nalsreectedintheareaimmediatelyunderthelevel
metercanbeevaluated.The zone(Fig.2)determines
the min. distance possible between the level meter
andthehighestsurfacelevel.Themin.distancesto
themediumaregiveninthechapter"Specications".
• Itis necessary to installthe level meter sothat the
binlevelcannotinterferewiththe deadzonewhen
lled up to the maximum. If the measured level in-
terfereswiththedeadzone,thelevelmeterwill not
workproperly.

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 for explosive areas (ULM–70Xi–_ _–I), level meters must be grounded with
ground terminal! It will be done using a screw placed on the head of the level meter under
the cable bushing.
The 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.
6 . elecTrical connecTion
The ultrasonic level meter is designed to be connected to supply unit or to controller through
acablewiththeouterdiameterof6÷8mm (recommendedcross-sectionofcores0.5 ÷0.75
mm2)bymeansofboltedclipsplacedunderdisplaymodule.Connectthepluspole(+U)tothe
terminal(+),theminuspoleto0Vtotheterminal
(-)andtheshieldingtotheterminal( )(onlyfor
shieldedcables).
Procedure to connect the cable to the level
meter:
1. Unscrewthenutoftheuppertransparentlid.
2. Take the upper edge of the display module
andtakeitoutcarefullybymildswingingup.
3. Ifyoucannotgraspthemodule,youcanuse
a small screwdriver. Insert it as far as the
seamandusefromseveralsidestoslightly
liftthemodule.
4. Release the cable bushing and thread the
strippedsupplycablein.
5. Connect the cable into the bolted clips ac-
cordingtothediagraminFig.14.
6. Assemblethelevelmeterandconnectthe
cabletothesequentialunit.

If during the scanning of the tank in the bottom of the display ap-

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.
