4.9.7.2 Impulses per litre
Hint!
x The requires the calibration value "Im-
pulses per litre" for the flow meter / return flow meter
x for determination and control of the spray rate [l/ha].
x for the determination of the daily and total amount of
the sprayed spray cocktail [l].
x In case the calibration figure is not known you have to de-
termine the calibration value "Impulses per litre" via a cali-
bration of the flow meter /return flow meter.
x If the calibration figure is exactly known you can manually
enter the calibration value "Impulses per litre" for the flow
meter / return flow meter into the
.
Important!
x For the accurate conversion of the spray rate in [l/ha] you
would have to determine the calibration value "Impulses per
litre" of the flow meter at least one a year.
x As a matter of principle determine the calibration value "Im-
pulses per litre" of the flow meter:
x after removal of the flow meter.
x after a prolonged period of operation as there may be
deposits of spray agent residue may in the flow meter.
x in case of deviations between the required and the ac-
tually applicated spray rate [l/ha].
x For the accurate conversion of the applicated spray cocktail
amount in [l] align the return flow meter with the flow meter
at least once a year.
x Align the return flow meter with the flow meter:
x after the determination of the calibration value "Im-
pulses per litre" of the flow meter.
x after removal of the flow meter.
x Take down the indicated value "Impulses" when you drive
the field sprayer away from its position for the determina-
tion of the sprayed amount of water.
