Flow Meter
The flow meter on your unit is the green device inline with the plumbing on the pressure
side of the pump. This vital instrument tracks the flowrate and volume going to your
spray boom sections and your hose reel if so equipped. This realtime reading is what
tells your GPS rate control system to increase or decrease the flow rate to your boom
based on your speed by opening or closing your proportioning valve (see next item).
The image below shows your flow meter as viewed from the back of your spray unit.
These magnetic flow meters never require re-calibration due to the use of different brine
blends like a conventional turbine flow meter would.
Proportioning Valve:
The proportioning valve is what regulates the flow to your spray boom based on GPS
speed inputs when spraying in “auto” mode or user inputs for desired gallons per minute
by the user when using “manual” mode. The proportioning valve is pictured below as
viewed from the back of the sprayer and clearly indicates full flow (all the way counter
clockwise, 9 o clock) or closed (all the way clockwise, 12 o clock).
