4.9 Volumetric measurement and calibration
4.9.1
General
The actual spraying pressure and nozzle wear are determined with the volumetric
measurement.
A volumetric measurement is always necessary if the output quantity of the
machine deviates from the output quantity in the spraying table of the nozzles
used.
The volumetric measurement must be done during first use, before every spraying
season or in the case of nozzle wear or replacement.
It is recommended to have the equipment checked annually by a specialist.
The pulse values of the speed sensor and the flow meter are determined with the
calibration. - see the operating instructions of the on-board computer or operating
terminal for this.
ATTENTION! The fitting type 1, e.g. 1.99, must be input for the Spraydos on-
board computer.
Only use clean water for the volumetric measurement and calibration.
4.9.2
Checking the nozzle output
Volumetric measurement:
Volumetric measurement of at least 3 nozzles must be carried out in order to
determine a precise value of the nozzle output.
A hose can be pushed over the nozzle for collection or a suitable container can be
held under the respective nozzle by a second person so that nothing can flow past
the container.
Checking the nozzle output is done while stationary (on-board computer or
operating terminal in the “MAN” position.
- Fill the machine with water.
- Operate the pump at the specified speed.
- Put the individual components in the spraying position.
- Adjust the specified spraying pressure using the regulator valve.
- Hold the collecting container under the collection hose or directly under the
nozzle for one minute and pour into the measuring container; repeat the
process for at least
two nozzles.
