The sensors can also detect movement if doors, gates and other moving parts are in their range. The below
drawing show a circle which indicate a perimeter not to install any movement parts closer than 2*m that
can disturb the count sensors. (m) is the distance between the sensors and we recommend a perimeter
from center of the circle on 2*m.
In some installations, a delineator to separate the lanes must be used to increase the performance of the
counting system.
Example:
If a car is driving in the middle of the lane, the counting system is at risk of not counting correctly because
the sensors may fail detect it. To increase counting accuracy, it might be advantageous to place a delineator
between the two lanes to avoid cars driving in the middle of the lane.
Bumper-to-Bumper
If cars are driving bumper-to-bumper, the sensors are not able to distinguish the cars from each other, and
the counting becomes incorrect.
The mounting height of the count sensor influences how close the cars can drive before the sensor can no
longer distinguish one from the other.
If the sensor is mounted at 2.5 m, the distance between the cars must be at least 1.10 m to make each car
distinguishable to the sensor.
If the sensor is mounted at 2.0 m, the distance between the cars must be at least 0.90 m to make each car
distinguishable to the sensor.
