ImpOrTANT NOTICE
Use TM Series meters with water and other
chemicals compatible with wetted components
(see Specifications Section). Do not use to meter
fuel or incompatible chemicals. TM Series meters
are available with either a computer for local
electronic display, or a conditioned signal output
module to provide a digital signal to customer
interfacing equipment. TM Series meters with
computer display measure in gallons or litres.
Refer to the Calibration Section for details.
These meters are not legal for trade applications.
TM Series meters are very sensitive to electric
noise if operated within 1 to 2 inches of some
electric motors or other sources of electronic
noise.

INSTALLATION
Connections
Install your meter in-line either horizontally or
vertically or at the end of the hose adjacent to
the nozzle. Installation to metal connections is
not recommended. Install as follows:
1. Plan to install turbine with a minimum straight
pipe length as follows:
• Upstreamfromtheturbine,allowamini-
mum straight pipe length of 10 times the
internal diameter of the turbine.
• Downstream from the turbine, allow a
minimum straight pipe length of 5 times
the internal diameter of the turbine.
2. For Spigot (Pipe) End use only primer and
solvents approved for PVC gluing.
Cut to Length The meter housing can be
shortened by the customer. Each meter has
a “dotted” line feature molded on the top
surface of the housing tube. The housing
can be cut up to this line without harming
any internals.
Most glue on fittings will fit without interfering
with the computer display area. However,
the customer should check all parts before
attempting cut.

the appropriate screws. Reconnect the wires
in the proper positions and tighten the screws.
3. Install the batteries. Make sure the positive
post is in the correct position.
4. Position the module on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the front of the module.
Ten feet (3 m) of cable is provided with the module. Trim the cable to desired length or extend
it as necessary.
Verify Meter Accuracy
Before using, check the meter’s accuracy and
verify calibration.
1. Make sure there is no air in the system by
starting the flow until it runs steadily. Then,
stop or divert the flow using a valve or nozzle.
2. Meter an exact known volume into an accurate container. For best results, meter with
one continuous full stream.
3. Check the volume against the display or
recording equipment. If the amount metered
is accurate, further calibration is not necessary. If not, refer to the Calibration Section
for further instructions.
OpErATION
Computer Display –
Batch and Cumulative Totals
The computer maintains two totals. The Cumulative Total provides continuous measurement and
cannot be manually reset. The Batch Total can
be reset to measure flow during a single use. The
Cumulative Total is labeled with TOTAL 1, Batch
Total is labeled TOTAL 2 BATCH.
When the Cumulative Total reaches a display
reading of 999,999 the computer will highlight
an X10 icon. This indicates to the operator that
a zero must be added to the 6 digits shown.
When the next rollover occurs, the computer
will highlight an X100 icon. This indicates to the
operator that two zeroes must be added to the
6 digits shown.
Press the DISPLAY button briefly to switch
between the TOTAL 1, TOTAL 2 BATCH and
FLOWRATE. Press DISPLAY briefly to display
the TOTAL 2 BATCH. Hold the DISPLAY button
for 3 seconds to reset the Batch Total to zero.
When fluid is flowing through the meter, a small
propeller icon is highlighted.
NOTE: Totalization counts total units without
differentiating between gallons, litres or field
calibrated units.
Flowrate Feature
To use this feature, press and release DISPLAY
until FLOWRATE icon appears. The factory
set time base will be highlighted to the right of
FLOWRATE (M = minutes, H = hours, D = days).
When FLOWRATE is invoked, the display will be
indicating rate of flow.
Activate the Meter
Computer is on continuously and always ready
to perform. The computer is powered by field
replaceable batteries. When display becomes
dim, faded or the low battery message appears
(see below), the batteries need to be replaced.
Reference the Maintenance Section for details.
Factory and Field Calibration
All calibration information is visible to the user
as icons on the top line of the display, above the
numeric digits.
All units are configured with a “factory” calibra-
tion.Bothgallonsandlitresareavailable(“GL”
or “LT” will be displayed). While holding the
CALIBRATE button, briefly press DISPLAY to
toggle between gallons and litres. This factory
calibration (indicated with FAC) is permanently
programmed into the computer and is not user
adjustable.
NOTE: Your computer may have other units of
measure programmed into it. If so, holding the
CALIBRATE button and momentarily pressing
the DISPLAY button will toggle through all
factory set units. Other possible units are:
IGL(imperial gallon), QT (quart),CF (cubic
feet), CM (cubic meter), BL (42 gal. barrel),
CC (cubic centimeter) or OZ (ounce).

Switching between different units will not corrupt
theTotal’scontents.Forexample,inGLmode,
the computer totalizes 10.00 gallons, if the user
switches to LT mode, the display will read 37.85
litres (the same volume, different unit).
The “field” calibration may be set by the user, and
can be changed or modified at any time using
the calibration procedure described below in the
Calibration Section. Totals or flowrate derived
from the field calibration are invoked when the
FAC icon is no longer visible on the top line of
the display.
CALIBrATION
Verify Accuracy Before
Beginning Field Calibration
For the most accurate results, dispense at a
flowrate which best simulates your actual operating conditions. Avoid “dribbling” more fluid or
repeatedly starting and stopping the flow. This
can result in less accurate calibrations.
Make sure you meet the meter’s minimum flowrate
requirements:
TM Series Meters
3inchmeter 30GPM(113.6LPM)
4inchmeter 40GPM(151.4LPM)
The use of a uniformly dependable, accurate
calibration container is recommended for the
most accurate results. Due to high flowrate, it
is strongly recommended that calibration be
completed with a combination of volume and
weight using fine resolution scales.
For best results, the meter should be installed
and purged of air before field calibration.
Field Calibration with
Computer Display
Field Calibration and Factory Calibration are defined in the Operation Section. Factory calibration
settings are programmed into each computer
during manufacturing, using water at 70° F (21°
C). Readings using the Factory Calibration (FAC)
may not be accurate in some situations, for example, under extreme temperature conditions,
non-standard plumbing configurations or with
fluids other than water.
Field Calibration Procedures
(Correction Factor Method)
1. To calibrate, press and hold the CALIBRATE
and DISPLAY buttons for about 3 seconds
until you see FLdCAL. Release both buttons
and you will see CF - 00.0. You are now in
the field calibration mode and values from
-99.9% to +99.9% can be entered.

and hold both CALIBRATE and DISPLAY
buttons for about 3 seconds until FAcCAL is
displayed. Then release buttons. Unit should
return to normal operation and FAC icon is
visible.
Calibration with Conditioned
Signal Output Module
The K-factor of your meter appears on the
calibration report as the number of pulses per
gallon. The factor is determined during production using water at 70° F (21° C). This K-factor
may be used for “single point” calibration and
provide acceptable accuracy. However, readings
may not be accurate when using this calibration
method in some situations. For example, extreme
temperature conditions, non-standard plumbing
configurations or with fluids other than water.

mAINTENANCE
Proper handling and care will extend the life and
service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. However, it is important the rotor moves freely. Keep
the meter clean and free of contaminants.
The rotor can be removed for cleaning and inspection. Begin by unscrewing the nose cone from
the outlet end of the meter. A 1/4" square socket
extension can be used. Remove the lock and
flat thrust washers. Rotor can then be removed
from shaft. Note orientation because rotor is
not bi-directional. Remove debris or deposits
using soft brush or small probe. Reassemble in
reverse order.
CAUTION
Blowing compressed air through the turbine
assembly could damage the rotor.
CAUTION
Do not allow liquids to dry inside the turbine.
CAUTION
Batteries should ONLY be replaced with
P/N 113520-1 Kit (Includes two each P/N
902004-2 Batteries). Do not mix old with new.
Do not use other brands or technologies.
Open battery cells should be disposed
of in accordance with local regulations.
Lithium batteries are best disposed of as a
non-hazardous waste when fully or mostly
discharged. EPA does not list or exempt
Lithium as a hazardous waste. If waste
lithium batteries are still fully charged
or only partially discharged, they can be
considered a reactive hazardous waste
because of unconsumed lithium remaining
in the battery. Such batteries may qualify
as “Universal Waste” in many jurisdictions
within the U.S. and thus can be shipped for
disposal or recycling in accordance with
Universal Waste requirements.
If the display becomes dim, blank or the low
battery message appears (see below), replace
the batteries as follows:
CAUTION
Handle the rotor carefully. Small scratches
or nicks can affect accuracy.
NOTE: Make sure the arrow on the turbine outlet
is pointed in the direction of fluid flow.
Battery Replacement
The computer display is powered by two 3-volt
lithium batteries which may be replaced while the
meter is installed. When batteries are removed or
lose power, the batch and cumula tive totals and
the field and factory calibrations are re tained.
WARNING
(Battery) – Avoid mechanical or electrical
abuse. Batteries may explode or cause
burns, if disassembled, crushed or exposed
to fire or temperatures in excess of 212°F
(100°C). Do not short circuit or install with
incorrect polarity. DO NOT INCINERATE.
