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.
