Note. Some countries,
such as the UK, have
their own variant
of these mounting
guidelines due to
differences in road
layouts and traffic
profiles. Please
consult with your
local Wavetronix
office to ensure
you are installing
to the correct local
guidelines.
Warning. Choosing
a mounting height
outside that range
could negatively affect
sensor accuracy.

Additional information
If the roadway is frequently used by tall vehicles, consider choosing a
˿
higher mounting height to help avoid occlusion.
Don't use an offset of less than 6 ft. (1.8 m). Also, the sensor can be
˿
up to 230 ft. (70.1 m) from the road, but don't go out that far if you
can avoid it; it could lead to decreased accuracy.
For best results, choose the mounting height in the Height column
˿
in the table. If you can't, just keep it somewhere in the acceptable
range.
