Example:
Using the above example of 40 l/ha application rate in trees planted at 2 m distance
with two Undavina 400 heads each 0.4 m (0.8 m total) on an area of 5 ha.
The required tank contents for the Undavina spray heads will be:

Setting the Output Flow Rate

Wear Gloves
 Calculate the required flow rate per atomiser or nozzle using the formula or look
up tables provided in section 5 and 5.1 of this document.
 Flow rates should be set first using water only. Recheck the flow rate with the
actual spray mix to be used before spraying.
 Always conduct flow checks in a secure area where there is no risk of run-off of
spray liquid into waterways or drains.
 Ensure any spillage or washings are contained refer to section 8.1.

5.5.1 Output Flow Rate CDA Atomisers

Where an adjustment valve is fitted to the flow gauge
 Open the valves fully on each flow gauge with the pump operating
 Adjust the pressure regulating valve so that each gauge is reading 50% higher
than the required flow rate.
 Adjust each individual flow gauge to the required flow rate.
Where no adjustment valve is fitted to the flow gauge
 Set the flow by adjusting the main pressure relief valve on the return to tank.

Where an orifice restrictor is fitted in line it may be necessary to change the
restrictor size to achieve the required flow rate.
Note: the flow gauges used with CDA rotary atomisers are calibrated in l/hr
