IMPORTANT NOTICE

Use TM Series meters with water and other
chemicals compatible with wetted compo­nents. 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.

SAVE THESE INSTRUCTIONS

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:

•

Upstream from the turbine, allow a mini-

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.

For NPT and BSP Fittings wrap all connec-

tions with 3 to 4 wraps of thread tape (optional
to use pipe thread sealant). Make sure the
tape does not intrude into the flow path.

3. Attach meter with arrow pointed in the direc­tion of fluid flow.

4. For NPT and BSP Fittings - Hand tighten
the meter at the housing ends. Do not use
a wrench or similar tool to tighten. This can
damage the housing.

Resistor

To protect against leakage, seal all pipe
threads with an appropriate sealing com­pound. Make sure the sealing compound
does not intrude into the flow path.

NOTE: If connecting to new male pipe threads,

burrs and curls can adversely affect accu­racy. Correct the problem prior to turbine
installation.

NOTE: Do not over tighten the flange bolts. This

may cause the gasket to be compressed
into the flow stream and may decrease the
accuracy of the meter.

Compatibility of this product’s material
and the process fluid and/or environment
should be considered prior to putting into
service.

WARNING

Product should never be operated outside
its published specifications for temperature
or pressure. See specifications for your
model.

WARNING

Make sure flow and pressure have been
eliminated from process pipe prior to
installing or removing product.

WARNING

Always use appropriate thread sealant or
flange gaskets when connecting product
to

process piping.

WARNING

Installation near high electromagnetic fields
and high current fields is not recommended
and may result in inaccurate readings.

Conditioned Signal Output
Module Wiring

This conditioned signal output module can be
wired to provide an open collector signal output
or 6-volt square wave output.

Open Collector Signal Output

To achieve an open collector signal output,
reference Wiring Diagram 1. The terminal block
is located on the back side of the module. The
module is factory assembled for open collec­tor signal output. Please provide the (820 ohm
minimum) resistor.

Ten feet (3 m) of cable is provided with the
module. Trim it to desired length or extend it as
necessary. Distances up to 5,000 feet (1,524 m)
can be achieved for open collector signal output.

Square Wave Output

To achieve square wave output, reference Wir­ing Diagram 2 and use an Electronic Digital
Meter Battery Kit (sold separately) for battery
power. The terminal block and battery location
are located on the back side of the module.
Access as follows:

1. Remove the four Phillips-head screws from
the front of the module and lift the module
from the turbine.

2. To change terminal block connections,
loosen 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.
