USING THE FLOW METER TO CALIBRATE THE
TANK:
1. Enter in the Meter Cal value as given on the white
Calibration sticker on the Flow meter.
2. Enter all the other calibration information needed
to enable the console to work.
3. Fill the tank to the top mark with water (i.e. 2500
or 3000 etc.). Make sure the tank is level.
4. Make sure the Total Volume reads "0"
Press [TOTAL VOLUME] then [ENTER] Enter "0"
then [ENTER]
5. Perform a self-test. (Choose a relatively high speed
and high rate so that the tank will empty relatively
quickly but make sure the pressure does not
exceed 60 psi).
6. When the tank is empty press [TOTAL VOLUME]
to read what the Raven Flow meter has output to
the booms.
7. If there is a large discrepancy (i.e. the difference
between theoretical tank volume and Flow meter
volume is greater than 100 litres), alter the Meter
Cal value accordingly. For example: If volume
reads 3100 litres instead of 3000 litres and the
original Meter Cal value is 185.

min) have to be entered into the console. The
console automatically starts on the first tier when
the boom master switch is turned "on" but it needs
reference points entered to be able to determine
when it should change to the second and third tiers.
Thus to achieve the three tiers two flow rate value
have to be entered.

8. Enter in new Meter Cal value and repeat
procedure (Step 3 to Step 6). Continue to
re-iterate the Meter Cal value until the desired
volume accuracy is achieved
9. Write down the appropriate Speed Cal value for
future reference.
1 . Re fill the tank to the top mark and perform the
self test again. Stop the self test after every 200
litres has been pumped out (read by pressing
[TOTAL VOLUME] and check how the water level
compares with the appropriate tank calibration
mark.
(i.e. After 200 litres has been pumped out there is
2800 left in a 3000 litre tank).
There may need to be extra marks put on tank to
indicate where the actual tank calibration levels are.

sing a no le chart determine the flow rates for
a single nozzle) at which point you wish the console
to change tiers. These points are best determined
by ascertaining the minimum pressure and thus the
corresponding flow rates at which point you wish
the next nozzle to cut in. Care must be taken to
ensure these minimum pressure flow rate settings
do not exceed the maximum recommended
operating pressure of the preceding nozzle.
For example: If you had XR110015 and XR110025
no les fitted to the sprayer the minimum pressure
that the R11 25's can cut in at is 1. bar. The flow
rate for an XR110025 nozzle at 1.0 bar is 0.57 L/min.
