844E Sprayer Control
Flow Meter
To ensure accurate readings, the
fl
ow meter (if used) must be
mounted 10
″
to 12
″
(25-35 cm) from other pipe
fi
ttings, preferably
in a vertical position with the
fl
ow going up. It should also be
mounted with the direction of
fl
ow arrow pointing toward the boom
control valves. Refer to Figures 1-2 and 1-3.
Be sure the
fl
ow meter is plumbed so that all liquid passing
through it is routed to the booms and not back to the tank. When
using three-way boom control valves, refer to page 25 of this
manual for programming guidelines.
Boom Control Valves
The Boom Control Valves are connected in tandem and centered
in front of the boom sections. See the Control Valve Instruction
Manual for mounting instructions. If using three-way valves, refer
to the instruction manual of the valves you are using for valve
calibration instructions.
Pressure Transducer
The pressure transducer (if used) should be installed as close to
the spray tips as possible. Normally this is at the boom control
valve assembly. Refer to Figures 1-1 through 1-3. Mount the unit
vertically on a short stand pipe to help protect the sensor.
NOTE: Pressure drop, to some degree, is found in most plumbing
systems. Pressure drop is created when there is any kind
of restriction in the spray line that reduces flow rate and
is quite often produced between the boom control valve
assembly and the spray tips. If one of the boom sections
on the sprayer is always used, the pressure transducer
can be installed on that particular boom section,
minimizing any potential pressure drops between the
sensor and spray tips. If the pressure drop in your system
is greater than 5 psi (0.3 bar), you should consider this as
an alternative location for the pressure transducer.
Check all components to make sure they are mounted securely to
avoid excessive vibration.
