FEATURES OF VARIANTS

Ultrasonic level meters ULM®is self contained device that includes electroacoustics transducer and electronic module. The

level meter ULM transmits series of ultrasonic pulses which propagates towards the liquid surface. Reﬂected acoustic wave is

received back in the ULM transducer and processed in electronic module. The distance calculations are based on time of ﬂight

of the acoustic wave to the level and back.

The level meters are suited to level measurement of various liquid materials, sewerage waters, mash and paste materials,

suspensions etc. In case the level of bulk-solid materials is measured, the measurement range is reduced. We recommend to

consult the use with the manufacturer.

All the setting is done by means of two buttons, located in the upper part of the sensor. Level meters are equipped with optimal

state indication "STATE" and the setting process "MENU". The level meters outputs can be current or voltage.

INSTALLATION

Level meter is installed into the upper lid of the tank (vessel), using a ﬁxing nut or a ﬂange.

If installed in an open channel (sumps, reservoirs, etc.), install the level meter as closest as you can to the maximum level

expected.

The front of the level meter must run in parallel to the measured level.

Emitted acoustic signal must not be affected by near objects (stiffeners, ladders, mixers, unevenness, etc.), stream of ﬁlling, air

ﬂow, etc.

Foam on the level absorbs the acoustic wave reﬂection which might cause malfunction of the level meter. If possible select the

location where the foaming is as low as possible.

Protect the level meter against direct sunlight.

In the case of uncertainty we recommend to consult the application with the producer.

LEVEL METER SETTING

The measuring range is setup by means of two buttons "DOWN"

and "UP".The "DOWN" button is used to enter to the setting mode

(setting the 4mA or 0V limit) and to decrease the output current

or voltage. The "UP" button as an opposite function (setting the

20mA or 10V limit and increasing the output current or voltage).

Values are conﬁrmed by simultaneous pressing of both buttons for

about 1sec. The setting process is indicated by yellow "MENU"

LED indicator.

For detailed information please read at the instructions manual.

RANGE OF APPLICATION

For continuous non-contact level measurement of liquids (water solutions, sewerage water, etc.), mash and paste materials (sedi-

ments, 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. We recommend to consult the use with

the manufacturer.

Slow ﬂashing (1–2 sec. depends on the measuring interval) – reception of reﬂected signal (echo) from the measured

level. Correct function.

Fastblinks– the measured value is in "dead zone" of the level meter, or the ultrasonic transm. is polluted.

STATUS AND FAILURE SIGNALIZATION

ELECTRICAL CONNECTION

The ultrasonic level meter is designed to be con-

nected to supply unit or to controller through two or

three-wire cable with outer diameter 6 ÷ 8 mm (rec-

ommended cross section of cores 0,5 to 0,75 mm2)

by means of connector which is included in delivery.

Connection diagram and inner view of the connector

as shown in picture. Always disconnect the power

supply before connecting the level meter electrically!

Note: In case of strong electromagnetic interferences

(EMI), parallel cable ducting with power lines, or when

cable length exceeds 30m we recommended to use

shielded cable.

WARNING:

With regard to possible occurrence of electrostatic

charge on non-conductive parts of the level meter, me-

tallic ﬂanges of the ULM-53Xi-10-I and ULM-53Xi-20-I

(for explosive areas) level meters must be grounded

with ground terminal!
