3. Sensor Installation
3.1 Installation Location
When installing EM500-UDL, please take in mind:
Ensure the location of EM500-UDL is within the communication range of LoRaWAN gateway.
Device must sit in a vertical position on top of the object and be fitted such that it has a
clear path to the object.
Place device where it is not close to side-wall and without internal obstructions that block
the ultrasonic signal. (Position 1)
Position 2 is the ideal location to install EM500-UDL.
Do not place device in the center of arched or circular container tops since it will cause
multiple echos. (Position 3)
Do not place the device above the container inlet orifice.(Position 4)
