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 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 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 measurement is not possible (Dead Zone). This distance can be
extended by programming in order to avoid disturbing effects of possible disturbing echoes 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.

3.1 ACCESSORIES
−Certificate of Warranty — 2 x M20x1.5 cable gland
−Installation and Programming Manual — SAP-200 Display Module (option)
−Declaration of Conformity — CD-ROM (EViewLight, DataScope softwares) (option)
3.2 SAFETY REGULATIONS FOR THE EX APPROVED UNITS
The level transmitter must be operated in intrinsically safe circuit only. (see values in Additional data for Ex approved models under Point 3)
For temperatures see values in Additional data for Ex approved models under Point 3
Transducer head of the models SE/SGA, SE/SGB and SE/SGT are made of plastic tending to charge up electrostatically, thus:
•The velocity of the filling and discharging process must be chosen according to the medium.
•During filling the material causing the hazard must be hindered from forming a mist
•It is not permitted to clean the plastic cover in explosion hazardous area
The apparatus is not suitable for flame-proof enclosure towards the external area.
The metal enclosure of the unit must be connected to the EP circuit
3.3 MAINTENANCE AND REPAIR
The EchoTREK SE/SG series do not require maintenance on a regular basis. In some very rare instances, however, the transducer may need a cleaning from
deposited material. This must be carried out gently, without scratching or pressing the surface of the transducer.
Repairs during or after the warranty period are carried out exclusively at the Manufacturers. The equipment sent back for repairs should be cleaned or
neutralised (disinfected) by the User.
3.3.1 SOFTWARE UPGRADE
Based on the observations & needs of our customers NIVELCO constantly improves and revises the operating software of the device. The software can be
upgraded with the help of the IrDA communication port of the SAP-200 or an ELink (USB) communication adapter plugged into the SAP-200 slot. For more
information about software updates please contact Nivelco.

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.

60/14 ♦BKI 03 ATEX 027X ♦sea3802a0600p_03
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 INSTALLATION AND ELECTRICAL CONNECTION
Installation of the (BSP or NPT) threaded models
•Screw the unit in to its place. Use open wrench for
tightening; max torque is 20Nm
•After tightening the enclosure can be rotated to the proper
position. (Safety bolt prevents rotation more than 350°)
•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.

•Ensure that the power supply is turned off at the source.
•With 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. Arrange grounding by the inner or outer grounding screw first.
•Switch on the unit and make necessary programming.
•After programming ensure proper sealing and closing of the cover.

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

60/16 ♦BKI 03 ATEX 027X ♦sea3802a0600p_03
5.1 PROGRAMMING WITHOUT DISPLAY MODULE
Programming is only possible if the EchoTREK is in Level Measuring
Mode and receives valid echo i.e. “VALID” 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)
