Thank you for choosing a HiTECH/NIVELCO instrument.
We are sure that you will be satisfied throughout its use.
1. INTRODUCTION
A Total beam angle of 5°-7°at –3 dB as is featured by most of
HiTECH/Nivelco’s SenSonic transducers ensuring a reliable measurement
in narrow silos with uneven side walls as well as in process tanks with
various protruding objects. Furthermore, as a result of the narrow beam
angle - the emitted ultrasonic signals have an outstanding focusing - deep
penetration through gases, vapour and foam is ensured.

Application
The EasyTREK compact ultrasonic level transmitters from HITECH/NIVELCO
are excellent tools for level measurement of liquids.
Level measurement technology based on the non-contacting ultrasonic
principle is especially suited for applications where, for any reason, no
physical contact can be established to the surface of the material to be
measured.
Principle of Operation
The ultrasonic level metering technology is based on the principle of
measuring the time required for the ultrasound pulses to make a round trip
from the sensor to the level to be measured and back. The sensor emits an
ultrasonic pulse train and receives the echoes reflected. The intelligent
electronic device processes the received signal by selecting the echo
reflected by the surface and calculates from the time of flight the distance
between the sensor and the surface which constitutes the basis of all output
signals of the EasyTREK.
Minimum measuring distance (Xm) is determined by the design of the unit within which the measurement is not possible (Dead Zone) its value is according
with P05 on page 26. Since measurement is impossible within this range material should not get into this zone.
Maximum measuring distance (XM) is the greatest distance (determined by the design of the unit) which can be measured by the unit under ideal conditions.
(See parameter P04 on page 25). Maximum measuring distance of the actual application (H) must not be greater than XM.

3. INSTALLATION
3.1 LIQUID LEVEL MEASUREMENT
POSITION
The ideal position of the EasyTREK is on the radius
r = (0.3 … 0.5) R of the (cylindrical) tank / silo.
(Take also sonic cone on page 1 into consideration.)
SENSOR ALIGNMENT
The sensor face has to be parallel to the
surface of the liquid within ±2-3°.
TEMPERATURE
Make sure that the transmitter is
protected against overheating by
direct sunshine.

10 / 38 ♦BKI 03 ATEX 027X ♦ spa3804a0600p_02
OBSTACLES
Make sure that no objects (cooling pipes, bracing members,
thermometers etc.) protrude into the sensing cone of the ultrasonic
beam.
Remark: EasyTREK programming allows one fixed object that would
otherwise disturb the measurement to be blocked out. (see P29 of
programming).
FOAM
Foaming of the liquid surface may render ultrasonic level metering
impossible. If possible, a location should be found, where foaming is
the least (device should be located as far as possible from liquid
inflow) or a stilling pipe or well should be used.
WIND
Intensive air (gas) movements in the vicinity of the ultrasonic
cone is to be avoided. A strong draft of wind may "blow away"
the ultrasound. Devices with lower measuring frequency (40,
20 kHz) are recommended.
FUMES / VAPOURS
For closed tanks containing chemicals or other liquids, which
creates fume/gases above the liquid surface especially for
outdoor tanks exposed to the sun, a strong reduction of the
nominal measuring range of the ultrasonic device is to be
considered during device selection. Devices with lower
measuring frequency (40, 20 kHz) are recommended in these
cases.
STAND-OFF
The structure of the stand off pipe should be rigid; the inner rim where the ultrasonic beam leaves the pipe should be rounded.
