sends the necessary control signals to the spray
system to maintain the application rate at that
designated by the operator.
Electromagnetic Interference - Externally generated
electromagnetic fields, such as those from a high
voltage transmission line, a vehicle alternator with a
bad diode, sparkplugs, etc., which can disrupt the
normal operation of an electronic device.
Flow Control System - A system that includes a
Control Console, a rate sensor device, and a servo
control. This system is designed to control product
to a target rate.
Flowmeter - A device which measures volumetric
liquid flow. MID-TECH uses two different basic
types of flowmeter.
Standard Flowmeters - Each standard flowmeter has
a standard range that it caaccurately measure. To
change ranges requires changing flowmeters.
Rapid Check Flowmeters - Similar ro a standard
flowmeter but has several different “ inserts” , each
with a different effective range, that can be
installed. To change the range of the flowmeter
just remove one insert and insert one having the
desired flow range.
GSO - Ground Speed Override is a minimum applica-
tion speed. When the vehicle speed drops below
GSO, the Control Console controls the output to the
GSO speed. Area is accumulated at the actual
ground speed.
Hydraulic Servo Control Valve – The term used to
describe a control valve that is capable of receiving
and acting upon increase and decrease information
from the Control Console and in turn controls the
flow of hydraulic fluid.
Impeller - A metallic device, similar to a propeller, used
in a flowmeter to monitor the liquid flow. Liquid
flowing past the impeller causes it to turn. A magnet
sensor, placed near the flowmeter wall, senses the
impeller blades as they pass and generates pulses
