Introduction
Before starting treatment, some settings are necessary to
inform the BRAVO30X about the characteristics of the vehicle
on which it is installed (by means of the wheel constant), the
characteristics of the liquid distributed (by means of the
density), the type of flow-meter connected and the type of
nozzle fitted.
Calculating the wheel constant
It may be necessary to change the wheel on which the speed
sensor magnets are installed, or the vehicle on which the
sensor itself is installed, meaning that the circumference of the
wheel changes.
In this case the constant on the BRAVO30X has to be changed
to allow it to measure the distance travelled correctly, and thus
make a correct calculation of the quantity of liquid delivered per
unit of surface area.
The wheel constant is the distance the vehicle travels for each
pulse received from the speed sensor.
The following is the procedure for calculating the wheel
constant:
Measuring the distance travelled in 10 turns of the wheel the
speed sensor is installed on (with the tyres inflated at working
pressure).
This is the formula to calculate the wheel constant:
Space travelled (m) x 10
= —————————————
number of magnets
Example:
- space travelled in 10 turns of the wheel = 25.4 m
- number of magnets installed = 10
The wheel constant is:
25.4 x 10
= ————————
= 25.4
