NOTE: For Negative Ground Systems Only
Your MT-9000 Series is equipped with an 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
in use.

Magnets
Illustration 3A
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. The
general rule for tractor or implement wheels is one magnet
for each wheel bolt (minimum of two, and always use an
even number). For drive shafts or small wheels (ATV’s), a
minimum of two magnets are required.
N
Illustration 3B
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 (meters). Divide that measurement
by 20 for English and Turf units, or by .5 for Metric units, and
then round up to the nearest even number (always use an
even number of magnets). That number will be the minimum
number of magnets required for the installation.
North

6
South
If your revolution measurement is 97 inches, dividing that
number by 20 gives you a value of 4.85. Rounding 4.85 up to
the nearest even number is 6. For this example, the minimum
number of magnets required is 6.

Example in Metric units
If your revolution measurement is 2.5 meters, dividing that
number by .5 gives you a value of 5. Rounding 5 up to the
nearest even number is 6. For this example, the minimum
number of magnets required is 6.
The magnets provided by Micro-Trak are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 3A.
NOTE: Refer to Appendix A for optional 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.
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 3B.
English or Turf (inches)
For proper operation, the magnets must be evenly spaced
around the wheel or drive shaft. They must have alternating
polarities, and the magnets must also be at least 1” apart.
See Illustration 3C.

Attaching Magnets
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 MT-9000 Series 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 following requirements.

correct sensor cable and connect it to the correct connector
on the main harness. The speed sensor and flow sensor are
identical, but must be connected to the proper harness
connector. The speed sensor always connects to the main
harness lead with the YELLOW tie and the flow sensor always
connects to the main harness lead with the GREEN tie.

installations in the cab or near the control console, it
may be more practical to use the local access connector
(YELLOW tie) on the control console pigtail exiting the rear
of the console. Using this connection point will disable
the connection point on the end of the main harness. For
speed sensor installations on implements, it may be more
practical to use the speed connector on the end of the
main harness. When using this connection point, make
certain that the local access connector for speed/distance

Calibration
General
In this chapter, we will help you calibrate your system
specifically for your NH3 application needs. Follow these
procedures carefully to make sure you are properly prepared
before you get to the field.
We’ll begin with the Special Calibration section. You will
need to go to Special Calibration anytime your system
uses a modified set-up. Modifications include: Metric or
Turf measurement, Servo type other than a Micro-Trak
servo valve, in-line (except NH3) versus by-pass plumbing,
ball valves versus solenoid valves. If your system does
not use any of these modifications, skip “Special”
Calibration and go to Standard Liquid Calibration on
pages 29-35.
This system is also equipped with a Software Utility package
that includes the “Calibration Wizard” program, that allows
you to calibrate your system electronically. See the Compact
Disc you received with your MT-9000 Series Automatic Rate
Controller and the Software Utility Reference Manual.
“Special” Calibration
Entering “Special” Calibration
The MT-9000 Series has a number of control functions which
are preset at the factory (See Factory Calibration Chart on
page 29). In some cases, however, it may be necessary to
change one or more of these settings to enhance performance
or meet special operational requirements. To make these
changes, you need to enter “Special” Calibration. To enter
“Special” Calibration, do the following:

being affected by any operation. This should be measured to
the nearest inch (thousandth of a meter).

Application Note: In certain situations when applying in
AUTO, your ground speed may be slow enough to result in
an over-application error. In other words, based on ground
speed, the actual flow rate for your application is below
the calibrated minimum. Remember, in AUTo, the system
will not allow the flow rate to drop below the calibrated
minimum.
Entering minimum flow values
Each target rate has a different settings for minimum flow.
Press the RATE 1 button. The lower right portion of the

Determining Wheel Circumference
Illustration 18
For the console to calculate the correct speed and measure
distance accurately, the circumference of the sensor-equipped
wheel must be entered. Determine the circumference of
the sensor-mounted wheel, to the nearest tenth of an inch
(thousandth of a meter), with the following method:
Mark the tire with a piece of chalk and measure distance
travelled on the ground for one complete revolution. See
Illustration 18. For improved accuracy, it is recommended
to perform this function in field conditions, measure several
revolutions, and take the average.
To determine circumference, measure the
distance of one complete wheel revolution
and divide by the number of magnets installed.
Divide the measured revolution by the number of magnets
installed to get your starting wheel circumference calibration
value. Once calibration of the system is complete, this
number should be fine-tuned for optimum accuracy. Please
refer to Fine-Tuning Speed/Distance Calibration Value on
page 33.

Fine Tuning Speed/Distance Calibration Value
3. P
lace the console in MAN when the marker on the vehicle
passes the starting flag to activate the distance counting
function. The console display numbers will increase,
adding to the distance total as you drive. Drive the premeasured course and place the console in HOLD when
the marker on the vehicle passes the ending flag to stop
the distance counting function. Stop the vehicle in a safe
and level area and continue with this procedure.
This procedure is used to verify the calibration of the system.
In order to achieve accurate measurements, each step in this
fine tuning procedure should be performed as precisely as
possible.
Preparation
• O
nce the system is fully installed and calibrated, select a
straight tract of ground that is similar to your actual field
conditions and as level as possible.
4. T oggle the “+/-” switch to adjust the upper display until
it matches the actual distance traveled.
NOTE: Using a course with a different ground surface,
such as a hard-surface road, will result in different
readings than exact field conditions.
5. W
hen the number shown on the display matches (as
closely as possible) the actual distance driven, you have
arrived at the correct calibration value. This will also finetune the Distance Cal factor in the lower right display.
• M
easure a distance of 1000 feet (500 meters). Clearly mark
the beginning and end points with flags or something
highly visible to the user.
To verify proper calibration, repeat the procedure a second
time. Write down the new wheel circumference (CIRC)
number (lower right display) and keep it in a safe place. If
the calibration values are ever accidentally changed, you can
simply re-enter this number.
Procedure
Warning: Turn boom switches OFF to avoid product
application during the following procedure.
1. P
lace the console in HOLD. The display will read HOLD.
Turn the rotary dial to the “Distance” position. Be
sure the display shows “0.” If not, reset the distance
counter by pressing and holding “Reset” until the
display automatically returns to 0 (approximately three
seconds).
MT-9000 SeRIeS
2. You are now ready to drive the measured course. Pick
a location on the vehicle to use as a marker for starting
and stopping the distance counting function (e.g. door
handle, mirror, step). You should begin to drive the
course well ahead of the starting flag and drive past the
ending flag, using the Master switch to start and stop the
counting function. It is not recommended to start from
a dead stop at the starting flag and stop at the ending
flag.

Fine-Tuning Flowmeter Calibration
Note: Total and Flowmeter calibration are inversely
proportional (meaning, as the Flowmeter calibration
value increases, total decreases).
This procedure is used to verify and fine-tune the flowmeter
calibration. Every flowmeter is calibrated with water at the
factory and stamped with a calibration value. Enter the value
as a starting point and use this procedure to fine-tune that
value for your specific installation and NH3 application (refer
to Entering Flowmeter Calibration on page 31. This procedure
should be repeated when the flowmeter installation has
been altered.
7. Y
ou will notice that the flowmeter calibration value has
changed. If the Field Flow value is correct, write down
the new flowmeter calibration value. This is your “fine
tuned” value. Keep this for future reference.
8. F lowmeter calibration is complete. Turn the rotary
selector to any position other than the calibration
positions (RED boxes with white type), and continue
operation.
Procedure
1. S tart with a full nurse tank. Make certain that you have
an accurate scaled weight of the full tank. You will want
to apply a minimum of 1,000 pounds of NH3 for this
procedure. The larger the volume of NH3 used, the more
accurate the calibration will be.
* One way to obtain a scaled weight of the total product
applied is to re-weigh the tank and subtract the current
weight from the previous weight. The difference will be the
total amount applied.
2. W
ith the power switch ON, turn the rotary selector to the
Field Flow position. Press and hold the RESET button
until the display reads 0.0 (about three seconds).
Illustration 19
3. Proceed to the field and perform actual application until
at least 1,000 pounds of NH3 has been applied. The
larger the volume of NH3 applied, the more accurate the
calibration will be. Obtain an accurate scaled weight of
the total product applied.*

Operation
Console Operation
display area
During normal operation, when the Auto/ man/hold
switch is in MAN and the Boom One switch is on, the
application rate will not be maintained by the console
automatically. For example, the MAN position may be used
by the user to do things such as spot applications.
During normal operation, the console will always display
application rate in the upper half of the display, and will
always display pressure in the lower left corner of the display
(when pressure sensor is installed). The lower right corner of
the display is used to show the data that corresponds with
the position selected on the rotary dial (top six positions are
operational positions).
Using the “+/-” switch while in MAN allows the user to control
the increase or decrease of flow or pressure as needed.
During normal operation, when the Boom One switch is
OFF, the console will turn the applicator off, application will
stop and acre, gallon and distance counters will stop. For
example, when turning on end rows, place the BOOM ONE
switch to the OFF position. This disables area and distance
counters.
For example, in the following illustration, the top half of
the display tells the user that Rate 1 is selected and the
application rate is 120.0 pounds of “N” per acre. The lower
left portion of the display tells the user that the operating
pressure is at 54 PSI. And with the rotary dial set to Speed,
the lower right portion of the display tells the user that the
current ground speed is 4.5 MPH.
“+/-” switch
The “+/-” switch serves many functions within the system,
and can be used within Calibration and Operation (Auto
and MAN).
Power switch
This switch controls 12-volt power to the entire system.
In the OFF position, there will be no drain to the vehicle’s
electrical system.
During normal operation, when automatic (AUTO) control
mode is active, Boom One is on, and the rotary dial is not in
a calibration position, each toggle of the switch will increase
or decrease the target application rate by the amount of the
calibrated adjust rate (“Delta”).

test button
The Rate buttons serve many functions within the system,
and can be used within Calibration and Operation (Auto
and MAN). The rate buttons allow you to quickly select
an alternative pre-programmed rate. They can be used in
several different ways.
This button is used during normal operation to check the
pounds of NH3 (Kg/NH3) remaining in the tank. With the
rotary dial in any of the six operational positions (BLUE and
GREEN), pressing and holding this button will enable the
upper half of the display to readout the pounds (Kg/NH3)
remaining in the tank. By releasing the TANK button, the
display will revert back to the application rate.
This button is used to enter the Test Speed mode when
calibrating the system. This button is NOT for use with
anhydrous ammonia application.
While in operation, the Rate buttons are used to select which
pre-programmed rate you will use during application. For
example, Rate 1 could be set at a low-end rate (e.g. 50 lbs.
“N”/acre), Rate 2 at a mid-range rate (Target, e.g. 100 lbs.
“N”/acre), and Rate 3 a high-end rate (e.g. 150 lbs. “N”/acre).

NOTE: FIELD FLOW and FLOWMETER are cleared together.
Field Operation
In hilly or rough conditions the nurse tank dip tube will not
remain submerged, allowing extra vapor in the system. This
vapor is too much for the heat exchanger to condense and the
system will exhibit erratic operation. If the dip tube remains
out of liquid, operation may appear to be normal, but the
system is simply metering vapor. If this occurs, you will notice
extremely low manifold pressure. Change tanks before the
NH3 level is low enough to cause these problems.
Always follow accepted safety precautions. Make sure that
equipment is in good operating order. Before connecting
the tank to the applicator, check the electric shut-off valve
for proper operation.
After changing tanks or after other periods of long shutdown, operate the system in MAN until the application rate
stabilizes. This allows the heat exchanger to reach operating
temperature before selecting AUTO. Erratic operation
may be experienced if AUTO is selected before operating
temperature is reached.
In NH3 control systems, location of the frost build-up is
an indication of system performance. The MT-9000 Series
system will normally have frost on the output side of the
servo valve and in some cases, a small amount on the bottom
portion of the heat exchanger. Frost before the servo valve
indicates excessive pressure drop in the delivery system or
restricted vapor lines.
Manifold pressure is very important for good distribution
of NH3. Use barbed fittings with properly sized orifices
or an adjustable manifold to maintain adequate pressure.
If manifold back pressure is too low, proper cooling will
not be achieved, vapor bubbles will be allowed to enter
flowmeter, and readings will be inaccurate. Typical manifold
pressure ranges from 15 to 60 PSI/1 to 4.1 bar depending
on application rates and ambient temperature. If manifold
pressure stops climbing but FLOW RATE continues to climb,
vapor bubbles are present.
The strainer is a common source of excessive pressure
drop and should be cleaned regularly. After completely
bleeding the system, remove the large plug and carefully
clean the strainer’s screen. Also, periodically check the vapor
tubes for obstructions.
32
Troubleshooting
General
Total NH3 Used is Inaccurate
All MT-9000 Series consoles, flowmeters and servo valves are
tested prior to packaging, so unless there has been damage
in shipment, everything will be operational when you receive
it.
Note: APP RATE refers to “N” (units of Nitrogen).
FLOW RATE, TOTAL and FIELD FLOW refer to NH3 (total
product).
However, if you do encounter a problem that appears to
be related to equipment failure, Please do not open
the console. Your system is protected by a warranty, and
Micro-Trak will gladly correct any defect.
This may result from an incorrectly entered Flow Cal value.
Check the number stamped on the flowmeter tag, and be
sure this is entered in the console’s Flowmeter position. If the
meter has been used frequently, wear may have changed the
Flow Cal value. See Fine-Tuning Flowmeter Calibration on
page 32.
Many problems are the result of mistakes in installation or
operation. Before returning any parts for service, carefully
check your installation and review the operating instructions.
For easy-to-follow guidelines, refer to the troubleshooting
section which follows.
Check to see that the flow sensor is screwed all the way into
the flowmeter.
Other causes may be a flow rate that is too low to register, or
foreign material lodged in the flowmeter.
Console Appears Dead
Using your MT-101 or homemade test light, check for 12
volts at the power source. Also check for damaged power
cable or reversed terminals. (Console requires 12 volts for
proper operation). Check for blown fuses.
6553.5 Message Displayed in Rate Mode
If this number appears when your equipment is standing still,
it indicates that the boom valve is open or not completely
closed and liquid is passing through the system.
Speed is Always Zero or Erratic
NOTE: 6553.5 may also temporarily appear when valves
are closed if liquid is sloshing back and forth through the
flowmeter, or if a portion of the line drains out. In this case,
no corrective action is required.
Check for properly calibrated wheel circumference.
Review speed sensor installation. Check for proper mounting,
alignment and spacing of speed sensor in relationship to
magnets. Make sure magnet polarities are alternated. Also
check cable for breaks or incomplete connection.
If this message appears when you are in motion with the
NH3 kit on, it indicates that speed sensor impulses have been
lost.
For more suggestions/solutions to speed problems, see Halleffect inputs and console inputs on pages 43-44.
Console is Erratic in Operation
Area Count is Inaccurate
If you have a two-way radio, it may be mounted too close to
the console. Keep all MT-9000 Series cables away from the
radio, its antenna and power cable.
Implement width or wheel circumference was measured
incorrectly or programmed incorrectly. Go back through
the original procedures, make changes, and test for acre
(hectare) count again. Verify accuracy with this formula:
Ignition wires may be causing the console to malfunction.
Keep MT-9000 Series cables away from ignition wires, or
install ignition suppressor.
Acres = Distance x Width (in feet) / 43560
Distance Count is Inaccurate
Wheel circumference was incorrectly measured or entered.
Review calibration, readjust and test.
Reroute all cables away from electric solenoids, air
conditioning clutches and similar equipment.
No Readout of Pounds, or Pounds per Minute
Displayed Measurements Do Not Make Sense
The console may be in the incorrect measurement mode
(English, Metric or Turf Units). See page 23 for details.
Check to see that all valves and related equipment are
operating properly. If material is flowing through the line,
check the flow sensor to be sure it is screwed all the way into
the flowmeter.
Display Reads “OFL”
Distance, Total Area, Sub Area, Field Flow and Total
Flow will read “OFL” when they have exceeded their
maximum count. Reset to zero to resume counting.
Check to see that a FLOW CAL number has been entered.
Also check cables for breaks or incomplete connections.
If the flowmeter is new or has not been used for a long period
of time, the turbine may be sticky. Flushing the system out
with water should make the turbine spin freely.
Flow rate may be too low to register a reading, or foreign
material may be lodged in the flowmeter.
33
Troubleshooting (cont)
Checking Individual Components
Console
Trak-Star Ultrasonic Speed Sensor
The only way to field test a console is to connect it to a
harness on a vehicle with a known working console or install
it on an E-POP (Electronic Point-of-Purchase) display stand.
Make certain that the Trak-Star is emitting a “crackling”
sound. If not, check for power at pins A (white) and B (blue)
of the adapter cable’s 6-pin connector. Also make certain
that the BLUE wire is securely connected to chassis (frame)
ground. Check connection for good metal-to-metal contact.
Harness
The harness can be checked using an ohmmeter or the
MT-101 (continuity tester). The main wiring diagram shows
the pin-out of all connectors. See page 19.
If the ground surface that you are traveling over is too
smooth (some blacktop and concrete surfaces, especially
wet, icy or snow covered), the speed reading may go to zero,
be erratic or be slow to respond. If the Trak-Star is making a
“crackling” sound and the ground doesn’t appear to be too
smooth, try mounting the Trak-Star pointing forward and as
far to the front of the vehicle as possible. (Echo interference
problem: See Trak-Star Installation and Operator’s Manual
for details.)
Electrical Interference
Erratic operation of the system may be the result of electrical
interference from ignition wires or inductive loads (electrical
clutch, fan, solenoid, etc). Always try to route wires as far
away from suspect areas as possible. If problems occur, you
may need to relocate the console and/or wiring harness, or
install a noise suppressor and/or spark plugs.
Power
The power cable has a three-pin connector labeled A, B, and
C. Check between A-C with a volt meter or test light. If there
is no power, trace cable toward battery looking for breaks.
Also check any fuses or circuit breakers that supply power to
the console.
Accessory Power
The speed, flow and run/hold cables all have an accessory
power wire. Check for 12 volts between B (usually white) and
C (usually black) of these connectors. If power is not present,
make sure the accessory power wire is not open or shorted
to ground or to another wire. If this wire has a problem, the
console may exhibit erratic behavior or not function at all.
Magnetic Hall-Effect Speed and Flow Sensors
Caution: Improper connection or voltage could damage
the Hall-effect sensor.
The Hall-effect sensor works similar to a reed switch, but
requires power in order to function. Also, this particular type
of Hall-effect sensor requires alternating magnetic polarities
in order to switch. This means that the north pole of a
magnet will “open” the Hall-effect and the south pole of a
magnet will “close” the Hall-effect. The Hall-effect will remain
“latched” without the presence of a magnet.
Ground pin C (black) and connect clean 12 volts to pin B
(white) of the Hall-effect sensor cable. Connect the positive
lead (red) of an ohmmeter or continuity tester to pin A (red)
and the negative lead (black) of the ohmmeter or continuity
tester to pin C (black) of the Hall-effect sensor cable.
Holding the tip of the sensor to the north pole of a magnet
should result in a very high resistance (infinite), while holding
the sensor up to the south pole of a magnet should result in
a very low resistance (near zero).
34
Checking Individual Components (cont)
Console Inputs
Ball Valves
If there is no response from any of the following tests, refer
to the main wiring diagram on the page 18 to locate the next
connector in line toward the console and repeat the test at
that connector. If there is a response at that connector, the
problem may be in the cable between the two connectors
(or the connectors themselves).
If the voltage reverses when switch is thrown, but valve
does not run, valve may be defective. Consult your valve
manufacturer.
Servo Valve Control Signal
The servo valve control signal cannot be checked without a
load. Connect a known working servo valve or other suitable
load (12-volt test light or 100-ohm resistor).
Speed Input: Turn the rotary dial to the speed position
and disconnect the speed sensor (yellow tie) from the
main harness. Check for 12 volts between pins B (white)
and C (black) of the main harness speed cable (yellow
tie). Using a clip lead or other jumper wire (such as a
paper clip bent in a “U”), rapidly short together pins A
(red) and C (black) of the 3-pin connector several times
(See Illustration 21). The console should respond with
some speed reading. If not, harness may be defective.
Check for cut or pinched wires. Make sure that the local
access is connected.
Turn console power switch to ON, place the console in “MAN”
mode and turn the boom one switch ON. Using a volt meter,
check from a good frame ground to each servo wire (red
and black on 3-pin, violet and gray on 10-pin). There should
be about six volts on each wire. Holding the “+/-” switch up
(“+”) should cause one wire (black or gray) to pulse from six
toward four volts and the other wire (red or violet) to pulse
from six toward eight volts. Holding the “+/-” switch down
(“-”) should cause the opposite results.
Servo Valve
Flow Input: Turn the rotary dial to the flow rate
position and disconnect the flow sensor (green tie)
from the main harness. Check for 12 volts between pins
B (white) and C (black) of the main harness flow cable
(green tie). Using a clip lead or other jumper wire (such
as a paper clip bent in a “U”), rapidly short together pins
A (red) and C (black) of the 3-pin connector several times
(See Illustration 21). The console should respond with
some flow rate reading. If not, harness may be defective.
Check for cut or pinched wires. Make sure that the local
access is connected.
The best way to test the servo valve is with a known working
console. Flip the power switch to ON, place the console in
“MAN” and turn all the boom switches ON. With the servo
valve connected to the servo valve lead on the main harness,
holding the “+/-” switch up (“+”) should open the servo
valve. Holding the “+/-” switch down (“-”) should close the
servo valve (provided the console has passed the Servo
Valve Control Signal Test). The servo valve should operate
smoothly from fully open to fully closed, in both directions. If
a known working servo valve will not run at all or takes more
than 20 seconds to run from fully open to fully closed, check

You may also use a 9-volt transistor battery. Connecting the
battery to each terminal on the servo valve should cause it
to run in one direction. Reversing the battery connections
should cause the servo valve to run the other direction. The
servo valve should operate smoothly from fully open to fully
closed, in both directions. Do Not connect 12 volts directly
to the servo valve. Damage may result.

Pressure Sensor
PRESSURE SENSOR Input: The only way to field test
The only way to field test the pressure sensor is to connect
it to a known working console, apply pressure and verify the
correct pressure reading on the console display.
the pressure sensor input is to connect it to a known
working pressure sensor, apply pressure and verify the
correct pressure reading on the console display.
Flowmeter
-------- Warning --------
Shaking the flowmeter end to end should produce a “rattling”
sound (shaft end play). Blowing in the meter from either end
should spin the turbine freely. If the turbine spins freely but
the meter will not register flow with a known working sensor,
the turbine may be defective. See Flowmeter Assembly and
Cleaning on page 41 for details.
To prevent serious injury, do the following:
1.Always wear gloves, goggles and other necessary
equipment when handling NH3 apparatus.
2.Do not cross thread. Use anti-seize lead base
thread compound.
Solenoid Valves
3.Thoroughly bleed hoses before disconnecting
NH3 apparatus.
If 12 volts are present between the two harness wires to
solenoid, but valves will not activate, consult the solenoid
valve manufacturer.

4.Completely evacuate NH3 apparatus before
servicing.
Plumbing Panel Harness
The MT-9000 Series NH3 plumbing panel harness is installed
on the plumbing panel at the factory. It connects the
flowmeter, servo, shut-off valve and remote access speed to
the main harness. This harness also contains the hold/cut-out
Hall-effect adapter, which disables flow pulses from reaching
the console when the shut-off valve is off.

Flowmeter Cleaning and Assembly
Important: Opening the flowmeter will void the Flow
Calibration value assigned to your unit. However, you may
need to take the flowmeter apart for periodic cleaning or
to remove an obstruction.
NOTE: The turbines have magnets built into the fins. There
are no visible magnets on the inside of the cavity.
On a flat surface, place each housing half on end. Set and
spin the turbine in each half. It should spin freely. If it does
not spin freely, remove the turbine, wipe the shaft and try
again. If is still does not spin freely, the shaft or bearings may
have excessive wear. (Service may be necessary).
If you can shake the flowmeter from end-to-end to produce
a “rattling” sound (shaft-end play), or if you can blow into the
meter from either end and cause the turbine to spin freely,
your flowmeter does not need cleaning. If you cannot hear
the “rattling” sound or get the turbine to spin freely, your
flowmeter needs to be cleaned. See Illustration 22B below for
reassembly instructions.
Assembling Flowmeter
Place turbine in non-sensor housing. Position Teflon gasket
on housing. (Teflon gasket may be reused, but will eventually
need to be replaced). Carefully set other housing in place.
Drop all screws into holes. Hold nuts in place and fingertighten screws. Making sure Teflon gasket is still properly
aligned, evenly tighten all screws. Attach tag.
Opening flowmeter
Cut the calibration tag retaining wire. Remove the screws
and disassemble the flowmeter. Do not attempt to remove
the sleeve bearings from the flowmeter housing.
After assembly, shaking flowmeter end-to-end should
produce a “rattling” sound (shaft-end play). Blowing into
the meter from either end should cause the turbine to spin
freely. If the turbine only spins from one direction, install the
flowmeter so that the liquid flows in that direction.
Use warm water and if necessary, a mild detergent and a soft
bristle brush to clean all parts. Do not use solvents or
diesel fuel to clean the flowmeter. A magnet works
well for removing fine metallic particles from the turbine.
Inspect all parts. Check for excessive bearing or shaft wear.
The shaft will wear shorter until the turbine drags on the
housing. Illustration 22A shows you what a new shaft looks
like. When both ends of the shaft are worn to the point of
drag, the turbine must be replaced.
Accuracy of flowmeter readings cannot be guaranteed for
flow rates below the meters’ ‘minimum pounds per minute’
rating. Recalibration is required before field operation.

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
with bolts, lockwashers and nuts provided. See Illustration
below. (Use self-tapping screws if bolts are not practi
cal.) Use either the short or long end of the bracket as
a base. (Allow enough room between the bracket and
the magnets so that when properly spaced, the tip of
the sensor will extend 1/4” [7mm] or more beyond the
locking nut.)
•
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 6 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.
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
NOTE: If you are using more than two magnets, please
follow the directions on page 9.
