Canopy width

Fig. 6

Depending on how the ultrasound sensors are moun-
ted to the tank or tractor, they will detect either the
trunk of the tree or its canopy.

The value to be entered in the computer is the
“CANOPY WIDTH”.

If the sensors are oriented towards the canopy,
set it to “0”;
if the sensors are oriented towards the trunk, the com-
puter must be told how wide the canopy is to open the
valves at the correct point for effective spraying.
This is done with the following calculation:

width of the canopy in meters (CW) less the dia-
meter of the trunk in meters (DT), divided by two:

LC – DT

—————

Therefore, in case of trees with an average width of 40 cm by the trunk and 3 m by the canopy, the
value to be entered is 1,3 m (Fig. 6):

3 - 0,4

= 1,3 m

If, on the other hand, the sensors are detecting the canopy and not the trunk, the value to enter will
be 0 so that when the canopy is detected, the computer will immediately begin treatment.
It is possible to program this function with up to 5 different types of canopy.
