2.2 Installation
To ensure correct operation and reliable and consistent level measurements, install the EGK-LW20L00
sensor in front of the target whose distance need to be measured. Screws are provided. Mounting
could be vertical or horizontal, depending on the application.
The device measures the distance to the closest target on its field of view. It works with different
materials, for example water level in rivers or flooded streets, snow height, waste or grains level in
bins or silos.
The measure is performed periodically according to parameter Period [min].
Custom brackets available on request.
2.2.1 Wall mount
For mounting onto wall, use the provided plate:

2.3 Power ON/OFF
The sensor is shipped completely off to prevent battery consumption during storage. It is therefore
necessary to carry out a first power-on prior to commissioning.
To power on the sensor: lay the magnet at the bottom of the provided tool into the area shown in the
figure:

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Successful power on is signaled by the flashing of the 3 LEDs.
In case of long period of inactivity, if necessary, is possible to shut-off again the sensor to prevent
battery consumption, via downlink or with LoRa Tool App:

2.5.1 Battery replacement
remove the front panel of the sensor with a small screwdriver:
remve the PCB batteries pack from the main board (PCB board is secured with two small
screws):

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Place the front panel and fix it with the 4 screws.
After the batteries replacement, internal counters need to be resetted.
To perform the operation, you need a unique reset code that must be requested to enginko (please
provide the DevEUI of the sensor when you ask for that code):

At the end of the procedure the battery level displays 100%.
2.6 Firmware update
Save the firmware file (.FW) on the smartphone, and upload it with LoraTool App:
3. Measures
On each reading of the sensor by LoraTool, the measured distance is shown on the main page:
2022/12/08 23:13 13/27 manual_egk-lw20l00
e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Once provisioned on a LoRaWAN® network, the device sends the distance & timestamp to the server
via uplink.
3.1 Level settings
Level measurements are carried out according to few parameter settings. A target over the defined
range cannot be detected. Read and write of parameters can be done using LoRaTool App. They have
a default value and can be modified to be tailored on the specific use case.
Meaning of parameters is related to following diagram. The “REFERENCE” (distance=0mm) is the top
surface of the sensor:

3.1.1 Start [mm]
Starting point of the measurement (in mm from “REFERENCE” point).
Values can be set from 350 to 6650:

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Default: 350
A target within the “Start [mm]” distance will result at a “Start” distance.
The “Start [mm]” value is also related to other level parameters. Contact enginko in case of
assistance.
