2 INSTALLATION
The NRV radar sensor is mounted directly using the hanger provided (or using the optional angle bracket).
Positioning and fastening are carried out using two M4 screws (3mm hex key).
To be able to perform measurement, the radome (radar antenna) must be parallel with the water level to be
measured (horizontal).
As the measurement cone is oval, the zone where the measurement is made and the potential presence of
obstacles in the cone are directly dependent on the sensor orientation (see diagram below).
As the angle of aperture is +/- 4° by +/- 6° with respect to the vertical, it is necessary to envisage offsetting the walls
by at least 10 cm (20 cm recommended) per metre of clearance.
To avoid any interference when it is sought to run 2 radars simultaneously, it is recommended not to install them in
the immediate proximity of one another. The minimum distance is dependent on the eddy currents of the water area
and the reflective surfaces located above it (the underside of a bridge, for example, the station ceiling, etc.), which
may require tests. In any case, the distance separating 2 radars should be at least equivalent to the clearance value.
