Thank you for choosing a 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 Nivelco’s
SenSonic transducers ensuring a reliable measurement in narrow silos with
uneven side walls as well as in process tanks with various protruding
ob
j
ects. 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 EchoTREK compact ultrasonic level transmitters from NIVELCO are an
excellent tool for the 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.
Such reasons may include corrosive attack by the process medium against
the measuring device material (acids), possible contamination (sewage) or
particles of the process medium adhering to the measuring device
(adhesive materials).
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 EchoTREK
Dead Band is a feature common to all ultrasonic level meters.
It is specified as “Minimum measuring distance” in the Technical Data
Table. Measurement within this range can not be interpreted.
Minimum measuring distance (Xm) is determined by the design of the unit within which the measuremnt is not possible (Dead Zone). This distance can be
extended by programming in order to avoid disturbing effects of possible disturbing echos coming from fixed objects. (Close-end Blocking).
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. The maximum measuring distance of the actual application (H) must not be greater than XM.

4. INSTALLATION
4.1 Liquid Level Measurement
POSITION
The optimal position of the EchoTREK 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 will
be protected against overheating by
direct sunshine.
Sunshade
8SE/SG-300 series two-wire compact ultrasonic level transmitters
STAND-OFF PIPE
The structure of the stand off pipe should be rigid; the inner rim where the ultrasonic beam
leaves the pipe should be rounded.

OBSTACLES
Make sure that no in-flow path or objects
(e.g. cooling pipes, ladders, bracing
members, thermometers, etc.) or no tank
wall of the ragged surface protrude into
the sensing cone of the ultrasonic beam.
One fix object in the tank / silo that
disturb the measurement can be blocked
out by the appropriate programming of
the EchoTREK

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 creats 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 units.
SE/SG-300 series two-wire compact ultrasonic level transmitters 9
4.2 Open Channel Flow Measurement
•For ultimate accuracy, install the sensor as close as possible above the expected maximum water level (see minimum measuring range).
•Install the device in a place defined by the characteristics of the metering channel along the longitudinal axis of the flume or weir. In case of Parshall
flumes supplied by NIVELCO the location of the sensor is marked.
•In some cases foam may develop on the surface. Make sure that the surface, opposite to the sensor remain free of foam for proper sound reflection.
•From the point of view of measurement accuracy the length of the channel sections preceding and following the measuring flume and their method of
joining to the measuring channel section are of critical importance.
•Despite of the most careful installation, the accuracy of flow metering will be lower than that of specified for the distance measurement. It will be
determined by the features of the flume or weir applied.
4.3 Electrical Connection
•After removal of the cover of the housing and taking out the
display module (if any), the screw terminals can be accessed.
Suggested cable core cross section 0.5 ... 1.5 mm2
•The unit has to be grounded by the inner or outer grounding
screw. For practical purposes units with plastic housing has to
be grounded by the outer grounding screw.
•The unit may be damaged by electrostatic discharge (EDS),
via its terminal, thus apply the precautions commonly used to
avoid electrostatic discharge e.g. by touching a properly
grounded point before removing the cover of the enclosure.
•
After connecting the cable and unit programmed proper
sealing and closing should be ensured.

4.4 Loop Curent Checking
After removing the cover (and the Display Module if there is any) the actual loop current can be measured with an accuracy of 0.5% by connecting an
ampermeter (in the range of 200 mV) to the points indicated on the drawing above
10 SE/SG-300 series two-wire compact ultrasonic level transmitters
5. PROGRAMMING
The EchoTrek can be programmed by the following two ways:
•Programming without Display Module see 5.1.
Assignment of the levels to the 4 and 20 mA current output, error indication by the analogue signal and damping can be set.
•With the SAP-200 Display Module, see 5.2.
All features of the unit can be set, such as measurement configuration and optimisation, 32-point linearisation, dimensions
for 11 tanks with different shape and for 21 different open channels (flume, weir, etc).
Devices with the type number EchoTREK SG... are already equipped with the SAP-200.
The EchoTREK is fully operational without the SAP-200. The SAP-200 is only needed for programming and/or displaying measurement values.
The unit will measure during programming in accordance with the previous parameters. The new, modified parameters will only be effective after
returning to the Measurement Mode
If the transmitter is left in Programming Mode by mistake, it will automatically return to Measurement Mode after 30 minutes and will operate with the parameters
entered during the last completed programming.
The EchoTREK will be delivered with the following Factory Default:
⇒Current output, display and bargraph: LEVEL
⇒Current output and bargraph proportional to the level
⇒4 mA: assigned to the minimum level 0%
⇒20 mA: assigned to the maximum level 100%
⇒Error indication by the current output: hold last value
⇒Damping: 60 sec
SE/SG-300 series two-wire compact ultrasonic level transmitters 11
5.1 Programming without Display Module
Programming is only possible if the EchoTREK is in Level Measuring
Mode and receives valid echo i.e. “ECHO” LED is lit !
The following can be programmed without display module
•Assignment of the 4 mA to a required e.g. min. level / max. distance
•Assignment of the 20 mA to a required e.g. max. level / min. distance
•Error indication by the current output (Hold, 3.6 mA or 22 mA)
•Damping (10, 30 or 60 sec)
•Reset to the factory default
Note: Current output can also be assigned in inverted mode:
4 mA = 100% (Full), 20 mA = 0% (Empty)
Procedure of programming: press button in the relevant sequence and check the state of the LED-s. Symbols for the states of the LED-s:
= LED is off, = LED is blinking, = LED is on, = LEDs are blinking alternatively = Dont care
