Flow Calibration for Balanced (Hardi) Valves
Because the Balanced valve system is used on Hardi Sprayers, the normal calibration procedure cannot be used. The following procedure is required for Balanced valve systems but it can also be used on "normal" valve systems.
1.Select Manual on the Sprayer Switchbox
2.Turn the pump and all Boom Sections on
3.Turn the Master ON
The Sprayer should start spraying
4.Adjust the pressure to the normal spraying pressure around the middle of the nozzle range
5.Ensure Display Volume/Nozzle is selected on the Flow window (page
The Flow Readout units will be volume (L or Gal)/noz.
The value displayed in the Flow readout window will be volume/nozzle/minute.
For this test to be accurate all nozzles on the boom spray must be the same type and the nozzles must be in good condition (not worn). The Flow Meter should also be in good condition for this test to be accurate.
6.Place a jug under a nozzle and time for 1 minute
7.Measure the volume of liquid coming out of the nozzle, this is the "Actual" amount
8.Write the "Actual" value down
