SAFETY
All operatio ns described in this instr uction manual have to be carr ied out only by trained personn el
or an accredited person. Warrant y and post warranty service must be exclusively c arried out by
the manufacturer.
Improper use, in stallation or set-up of the leve l meter can result in crashes in the a pplication (overfi 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.
MEASURING PRINCIPLE
®
The ULM
ultrasonic leve l meters are compac t measurement device s including an elec troacoustic
converter and a n electronic modu le. Using the electro acoustic conver ter, the level meters transmit
the sequence of ultrasonic pulses that spread towards the surface level. The converter recuperates refl ected acoustic waves that are subsequently processed in the electronic module. The
intelligent evaluation block fi lters out interfering signals, compares the cleaned received signal
with the false refl e ction map (e.g. from mixers, ladder s, reinforcement etc.) and selects a s uitable
refl 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 surfac e level is calculated. According to the level height, the level meter output is set and
the measured value is displayed on the display.
RANGE OF APPLICATIONS
For continuous no n-contact level measu rement of liquids (water solutions, sewe rage water, etc.),
mash and paste materials (sediments, sticks, resins etc.) in closed or open vessels, sumps,
reservoirs and open channels. In case the level of bulk-solid materials is measured, the measurement range is reduced.
The level meters c an continuously measure level s of bulk-solid materials with a low c oncentration
of dus
t particles. Consult the manufacturer on recommended use of the level meter for bulk-solid
materials.

INSTALLATION INSTRUCTIONS
Install the level meter in the • vertic al positi on into the upper lid of the tank or reservoir using
a welding fl ange, a fastening nut or a fl ange so that the level meter axis can be perpendicular to
the surface level of the measured liquid (Fig. 1).
The min. • dimensional parameters to install the
level meter into a lid or a ceiling of a tank are given
in Fig. 3.
When installing in an • open channel (reservoir, drain
etc.), install the level meter onto a b racket as close as
possible to the expected max. level.
In connection with the measurement principle, no •
signals refl ected in the area immediately under the
level meter can be evaluated (dead zone). The dead
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 "Technical specifi cations" (p. 24).
It is necessary to install the level meter so that the •
bin level cannot inter fere with the dead zone when
fi lled up to the maximum. If the measured level interferes with the dead zone, the level meter will not
work properly.

If the maximum surface level in the tank interferes with the dead zone, the level meter has •
to be mounted into a higher inst allation neck. In this way, the tank can be fi lled nearly up to
the maximum volume. The inner neck surface has to be even and smooth (without edges and
welded joints); the inner edge should be rounded where the ultrasonic wave leaves the pipe.
The neck diameter should be as large as possible but the neck height should be as low as
possible. Recommended dimensions of the input neck are given in Fig. 4.

During fi lling, mixing and other processes, • foam
can arise on the surface level of the measured
liquid. The thick foam considerably absorbs the
ultrasonic signal which might cause malfunction
of the level meter (Fig. 5). For such cases, it is
necessar y to set up "SENSITIVITY " mode (p. 14)
to "high" or contact the manufacturer if need.
If the emitted ac oustic signal of the level meter •
is affected by near objects (roughness on walls
of the tank, various partitions, mixers etc.), it is
necessar y to map false refl ections by activating
the mode "TEACHING" (see p. 14). In case of installed mixers, it is necessary to put the mixers
to position under the level meter (direct the mixer
blade to the ultrasonic signal beam).

The level meter must not be installed in places •
with direct solar radiation and must be protected
against weather effects.
If the installation in places with direct solar ra-•
diation is inevitable, it is necessary to mount
a shieldin g cover above the level meter.
It is suitable to run the cable under a cable bush-•
ing (obliquely down in slack) according to Fig. 10
to prevent penetration of humidity. Then the
rain and condensing water can fl ow off freely.
The cable bushing and connector have to be • suf-
fi ciently tightened to prevent penetration of hu-
midity.
To lower the minimum distance to the measured •
medium, a refl ection board made from solid,
even and smooth material can be installed to the
level meter. Then the tank can be fi lled nearly up
to the maximum height. The solution is suitable
for open tanks and reservoirs.
Scattering or attenuation of the ultrasonic signal •
can result if the surface level has been moder-
ately sti rred or rippled (by a mixer, coming liquid etc.). It can result in reduction of the measurement range or unreliable function of the level
meter (Fig. 12).
Rotating mi xer blades c an cause• that the sur-
face is stirred, which results in false refl ections of
the ultrasonic signal from the surface level and
unreliable operation of the level meter (Fig. 13).

Mapping of false refl ections lasts 5...30 sec.
according to the level meter type.
In case of installed mixers, it is necessary
to position the mixers under the level meter (direct the mixer blade to the ultrasonic
signal beam).
Note: If there are signifi cant obstacles in
the upper half of the tank, multiple false
refl ections can occur especially in closed
tanks. In such cases it is necessary to
reduce the level in the tank as much se
possible to correctly mask these possible
multiple false refl ections.

"MEDIU M TEMPER ATURE" (Temperatu re compen sation)
If the temperature o f the measured substance (li quid) in the tank is differe nt from the temperature whe re
the level meter is installed (see the mode "DIAGNOSTICS", p. 17), it is necessary to compensate the
temperature because of accuracy of the measurement. Af ter the medium temperature is set, the level
meter calculates a n average value (from the medium temper ature and the temperature where th e level
meter is installed) and uses this average temperature for calculation of the level position.
Inactive compensation (initial state), the word
"NO" appears on the display.
"FAILURE MOD E" (Fault condi tions)
It defi nes the output current of the level meter when the measured medium level is in the dead
zone ("DEAD ZONE") or outside the measurement range in case of echo loss ("NO ECHO").
NO ECHO: Current in case of echo loss (3.75mA)
DEAD ZONE: Dead zone current (22mA)
The values can be s et in three steps - 3 .75mA,
