4. Installation and use
4.1. Correct positioning of the AMR SENSORS transceivers
There are two key rules for optimising radio ranges.
•
The first one consists of positioning your product as high as possible.
•
The second one consists of limiting the number of obstacles in order to avoid excessive attenuation of the radio wave.
Position:
To the extent possible, install the transmitter at a minimum height of 1.50 m and do not attach it to the wall.
Obstacles
: Ideally, the product must be 20 cm away from any obstacle and, if possible, near an opening (the closer the obstacle is, the more
the emitted power will be absorbed). All the materials encountered by a radio wave will attenuate it. Bear in mind that metal (metal cabinets,
beams, etc.) and concrete (reinforced concrete, partitions, walls, etc.) are the most critical materials for the propagation of radio waves.

The AMR Sensors unit offers 3 fastening methods that enable numerous ways of positioning it depending on the environment where it has to be
deployed.

4.2.1 Tube or mast fastenings
As explained in section 4.1, the best radio
performance is achieved by positioning the
AMR Sensors unit as high as possible.
The fastening collar fastenings enable the
AMR Sensors unit to be fastened on a mast
or tube under completely safe conditions
