X20 Sprayer Reference Manual

Min. Flow

The Min. Flow allows a value to be entered which represents the minimum flow rate of the nozzles fitted on the Sprayer. This value can be found on the nozzle chart that came with the Sprayer.

When this value is entered the Spray Rate Controller will not allow the nozzle minimum flow to fall below the value set. The Spray Controller will hold the regulator at that position until the flow increases above the Min. Flow.

The Spray Controller knows what the total flow is, because of the feedback from the Flow Meter; it knows how many sections are switched ON and how many nozzles are on each section. Therefore, it can determine the flow per nozzle. When the flow per nozzle falls below the Min. Flow Value a red indicator will appear on the Flow readout, on the Working Screen (Figure 6-7 on page 6-7).

An explanation of the red indicator can be seen by selecting the Flow readout (button).
