Calibrating the flow meter with the nozzle method
 
When calibrating the flow meter using the nozzle method, you determine the average quantity of the liquid applied through a nozzle in a specific time.
 
 
Mode of operation
 
 
When calibrating using this method, you must apply clean water over the entire working width and measure the applied quantity on different nozzles using a measuring cup.
The flow meter measures the pulses during this time.
When you have finished the application, you must enter how much water was applied on average by one nozzle in one minute.
The computer calculates the number of pulses per litre.
 
 
 
Preconditions
 
 
 
þ
You have prepared a measuring cup you can use to measure the quantity sprayed.
þ
You have prepared a stopwatch to be able to count one minute precisely.
þ
All of the sections are open, and the sprayer can apply over the entire working width.
þ
Manual mode is activated (the  Hand icon appears on the work screen).
þ
The tank is filled with clear water.
þ
The set working width is correct.
þ
The number of nozzles per section and the number of sections are entered correctly.
1.
Ensure that all prerequisites have been fulfilled.
2.
Switch to the Flow pulses screen:
 DFM-Impulse Düsenmethode
⇨
The following screen appears:
 
3.
 Ampel - Start calibration.
⇨
The following function icons appear:
 OK - Stop calibration.
 ESC - Abort calibration.
4.
 Teilbreiten-Hauptschalter - Start application.
⇨
During application, the number of litres applied per minute is counted on the Flow pulses screen.
5.
Go to one nozzle and for 60 seconds carefully collect the water sprayed by using the measuring beaker prepared. Write down the quantity.
We recommend that you count the average from multiple nozzles.
6.
 Teilbreiten-Hauptschalter - Stop applying.
⇨
The application will be stopped.
⇨
No further litres are counted on the display.
7.
 OK - Stop calibration.
⇨
The volume line appears on the Flow pulses screen.
8.
 OK - Select the Volume line.
⇨
The Volume screen appears.
9.
Enter the average measured volume in litres.
10.
 OK - Confirm.
11.
 ESC - Exit screen.
⇨
You have calibrated the flow meter with the nozzle method.
