Tools Needed to Install Speed-O-Meter
• Screwdrivers and Nutdriver
• Electric Drill and Bits • Pliers
• Tape Measure
Installation
Required Tools
Installation of your SPEEDOMETER is basically a three-step
procedure. Each installation will vary somewhat, depending
on your type of equipment. Allowances for these differences
have been made through the design of flexible mounting
brackets and extra hardware.
Mounting the Display Console
Select a mounting location which seems most workable,
and best fits your needs. It should be convenient to reach
and highly visible to the operator. DO NOT INSTALL IN
A POSITION THAT OBSTRUCTS THE VIEW OF THE ROAD
OR WORK AREA. Whenever possible, avoid locations that
expose the console to direct sunlight, high temperature,
strong chemicals or rain.
Place the mounting bracket in the selected location, mark
holes, drill 1/4” (7mm) holes and mount bracket with bolts,
lockwashers and nuts provided. (Use self-tapping screws if
not practical to use bolts.) See Illustration 1.
Put rubber washers on carriage bolts and put the bolts
through the bracket holes from the inside out. Loosely
attach the mount knobs onto the bolts. Place console over
carriage bolt heads and tighten knobs to secure the console.
See Illustration 2.
Note: Some systems may use two “L” brackets in place of
the “U” bracket for console mounting.

Installation (cont)
Electrical Installation
Illustration 3
The SPEEDOMETER must be connected to a 12-volt DC
electrical system. Using your test light, locate a terminal or
wire connected to your ignition switch which is “hot” when
the ignition is turned on and “dead” when the ignition is off.
Locate the power cable on the main wiring harness. Connect
the RED wire to the contact point you have located. Attach
the BLACK wire (ground) to a screw or bolt on the equipment
frame. See Illustration 3. Be sure there is a good metal-to-
metal contact. The terminal connectors have been supplied
for your convenience. You may wish to substitute other
types of connectors or make direct solder connection. In
routing cable to console, avoid areas where the cable may be
subjected to abrasion or excessive heat.
Locate the single BLUE wire supplied with the kit to make a
ground wire. Crimp a female spade terminal on one end and
a ring terminal on the other end. Attach the spade terminal
end of the BLUE wire to the mating spade terminal on the
back of the console. Attach the ring terminal end of the BLUE
wire to a screw or a bolt on the equipment frame. Be sure
there is good metal-to-metal contact.
Your SPEEDOMETER is equipped with an advanced
electronic memory which does not require a constant supply
of power to retain daily totals or calibration values. The
advantage with this type of memory is that it conserves
battery power and will not discharge the vehicle’s battery
when equipment is not is use.
NOTE: For negative ground systems ONLY.

Speed Sensor Installation
PLEASE NOTE: If you have purchased an Astro GPS Speed
Sensor or a Vansco Radar Speed Sensor, disregard the
following section on magnetic speed sensors and install
the speed sensor as described in the instructions included
with the unit. See Appendix for adapter cables to connect
to some radars.
Locations where the sensor may be installed:
1. Non-driven wheel on tractor, vehicle or implement. This
is less susceptible to error resulting from wheel slip.
2. Tractor, vehicle or planter drive shaft. This type of
mounting is recommended for trucks, four-wheel drive
tractors or other equipment that has poor or no access
to a non-driven wheel.

Please read the following information about magnet spacing
and polarity.
The number of magnets that must be used depends on
the size of your tire and where you mount the sensor. On
tractor or implement wheels the general rule of thumb is one
magnet for each wheel bolt (minimum of two, and always an
even number). For drive shafts or small wheels (ATV’s), two
magnets are usually adequate.
Some installations may require that more than two magnets
be installed. To determine the number of magnets required,
measure the distance traveled of one revolution of the
sensor equipped wheel in inches (centimeters).
See the following tables to find the minimum number of
magnets required (always an even number)
Attaching Magnets to Hub
The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse is
sent to the FlowTrak II console every time a magnet passes
by the tip of the speed sensor. For the speed sensor to
operate properly, the spacing between the magnets and
the tip of the sensor must always remain constant. Before
permanently mounting any parts, be sure that the location
you have selected will meet the requirements shown in
Illustration 6.
NOTE: Observe magnet polarities (see previous section).

NOTE: Magnets may be attached mechanically or adhered
with epoxy or other high quality adhesive. When using
adhesive, thoroughly clean the area of dirt and oil.
The magnets provided by Micro-Trak are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 4.
Always use an even number of magnets, and always alternate
the polarities of the magnets as you go around the wheel
hub or drive shaft.
To install, mount the first magnet with the SOUTH pole side
(dashed line) facing toward the hub or shaft. Mount the
second magnet with the NORTH pole side facing toward the
hub or shaft. See Illustration 5.
For proper operation, the magnets must be evenly spaced
around the wheel or drive shaft. The magnets must be at
least 1” apart. See Illustration 5A.

adhesive such as epoxy.
2. Mount the speed sensor bracket to a part of the wheel
assembly that does not change position to the hub when
the wheels are turned. If the “L” bracket provided cannot
be bent and mounted to properly position the sensor,
make a bracket similar to the one shown at right.
3. Install sensor, adjust to correct spacing (1/4” to 1/2 “
or 6 to 13 mm is recommended), and secure with 3/8”
locking nuts.

Refer to the following diagrams for specific mounting
instructions. Magnets may be attached mechanically as
shown or adhered with epoxy or other high quality adhesive.
When using adhesive, thoroughly clean the area of dirt
and oil. With either method of attachment, wrapping the
magnets with a layer of electrical tape is recommended to
provide additional protection from field debris.
Two mounting examples are illustrated.
1. Using one cable tie (ribbed side down) secure two
magnets to the wheel hub so they are exactly opposite
each other. Alternate the magnets’ polarities. See page 8
for proper procedure.
2. Cut and bend sensor mounting bracket as needed and
rigidly mount. See Illustration 7.
3. Insert sensor, adjust spacing and secure with 3/8” locking
nuts.
NOTE: Observe magnet polarities (see page 8).
CAUTION: Make sure valve stem cannot make contact with
cable, sensor or bracket.

or 6 to 13 mm is recommended), and secure with 3/8”

Speed Sensor Mounting on Drive Shaft
Determine the best location for the magnets on drive shaft
according to which is the most practical spot to attach sensor
mounting bracket. This position should be no more than 12”
(.30 meters) behind the front U-joint. For best results, mount
“L” bracket to transmission and mount magnets on drive
shaft as close to transmission as possible. This will ensure
proper alignment if drive train shifts under heavy loading.
Two magnets are required for proper Hall-effect speed
sensor operation. Position them exactly opposite each other
(180 degrees apart). The polarity (north and south poles)
detected by the Hall-effect speed sensor must alternate as
the shaft is turned. The magnets provided by Micro-Trak are
marked with a punched dashed line on the SOUTH pole side
of the magnet.
• Attach magnets onto drive shaft, one NORTH pole side
out and the other SOUTH (dashed) pole side out, by
wrapping cable tie around shaft and magnets. Position
each magnet so that its longest dimension moves in
the direction of rotation. Pull cable tie tight and trim
off excess. An adjustable, non-magnetic (stainless steel)
band clamp may also be substituted.
• Attach sensor bracket to vehicle transmission. See
Illustration below. Use either the short or long end of
the bracket as a base.
• Turn one locking nut onto threaded sensor and insert
sensor into large hole selected on mounting bracket.
Turn on remaining locking nut. Set sensor to proper
distance from magnets (1/4” to 1/2”, or 6mm to 13mm).
When distance is set, tighten nuts to lock sensor in
place.
• Secure sensor cable to frame with cable ties. Place first
tie as close to sensor assembly as possible.
