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:
