Q =
Spraying volumes may be obtained using
the formula.
Where:
Q: Spraying volume (L/ha)
q: Nozzle flow rate (L/min)
f: Nozzle spacing (m)
v: Tractor speed (km/h)
495: Conversion unit

Calibrating the sprayer
1. Mark off 50 meters or 164.04 ft on the
ground to be sprayer.
2. Fill up the sprayer.
3. Choose the working gear.
4. Engage the PTO.
5.
Accelerate until reaching 540 rpm at the PTO.
6. Start moving at least 5 meters before the
initial mark.
7. Note the time it takes the tractor to move
50 meters or 164.04 ft.
Ex.: Nozzle flow rate: 1,0 liter at 150 PSI² (JA
- 2 Nozzle)
Nozzle spacing : 0,5 m
Before calibrating the sprayer be sure:
• Suction filter is clean.
• Hoses are not twisted or bored.
• Pressure regulator components (valve seat,
valve and spring) are not worn or dirty.
• Pump is properly lubricated (oil level and
grease) and has no leakage.
• Nozzles are of the same model, not worn,
with correct flow rate and with clean
strainers.
After checking, proceed to calibrate as follows
