TEKELEK LoRaWAN Installation Manual

LoRaWAN Ultrasonic Sensor
Installation Guide
Thank you for purchasing the Tekelek LoRaWAN Ultrasonic sensor which is
an ATEX certified LoRaWAN flexible and configurable battery-operated
level sensor with an integrated LoRaWAN radio.
Safety Information:
The LoRaWAN Ultrasonic sensor is ATEX compliant, but if installing in a
harsh environment first check local applicable regulatory and safety
guideline to ensure installer security. Please refer to the Short Instruction
Manual for more information on the warnings and hazards.
STEP 1: Installation
Note: For the LoRaWAN sensor, warnings detailed in the Short Instruction
Manual must be considered.
When possible, install the LoRaWAN sensor as high as possible off the
ground (>2meters is ideal).
The LoRaWAN sensor can be easily mounted in these different ways:
(screws & cable ties not provided)
•
Wall mounting with M6 screws
•
Vertical tube mounting with polyamide cable ties
•
Horizontal tube mounting with polyamide cable ties
•
Sensor may also be glued in place if required
These different configurations are detailed in the following steps.
1
1.1 Wall Mounting
The LoRaWAN sensor has a wall mount system for M6 screws. When
mounting, ensure that the antenna is vertical and avoid having the
antenna too close to another wall, or any obstacle.
Figure 1: Example of wall mounting
1.2 Vertical tube mounting
Mounting and installation of the LoRaWAN sensor on a vertical tube:
•
Use 1 weather resistant polyamide cable tie (width < 5mm and
length > 250mm)
Follow these steps:
•
Position the LoRaWAN sensor on the vertical tube
•
Insert cable ties through holes on underside of the sensor
•
Tighten the cable ties so that the sensor is held securely in place.

1.3 Horizontal tube mounting
Mounting and installation of the LoRaWAN sensor on a horizontal tube:
•
Use 2 weather resistant polyamide cable ties (width < 5mm and
length > 250mm)
Follow these steps:
•
Position the LoRaWAN sensor on the horizontal tube
•
Tighten the cable ties so that the sensor is held securely in place.

STEP 2: Antenna considerations
The position of the LoRaWAN sensor and its antenna is key in the
performance of the LoRa network. The position and the orientation of the
LoRaWAN sensor must be chosen carefully to offer the best performance.
Some recommendations are provided below.
•
Orientation:
The antenna must be kept vertical, in the nominal position of the LoRaWAN
sensor.
•
Metal plate, metallic parts:
Performance of the antenna may be degraded by metal parts within 20cm
above or beside the antenna
•
Height / ground effect:
The ground has a significant impact on the radio signal attenuation. The
closer to the ground the LoRaWAN sensor is, the higher the attenuation will
be.
•
Sensor interface:
The cable between the Rochester gauge and the LoRaWAN sensor should
be guided such that it is not close to the antenna. Also avoid creating any
loop with the cable, close to the LoRaWAN sensor enclosure.
