IMPORTANT NOTICE
Use TM Series meters with water only. Do
not use to meter fuel or chemicals. TM Series
meters measure in gallons or litres. Refer to
the Calibration Section for details.
These meters are not legal for trade applica-
tions.
TM Series meters are very sensitive to
electric noise if operated within one to two
inches of some electric motors or other
sources of electronic noise.

INSTALLATION
Install your meter in-line either horizontally or
vertically or at the end of the hose adjacent
to the nozzle. Installation to metal connec-
tions 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
minimum 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. Use only primer and solvents approved
for PVC gluing.
3. Attach meter with arrow pointed in the
direction of flow.
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 the flow using a valve or
nozzle.
2. If desired, hold down DISPLAY for 3
seconds to zero the meter's Batch Total.
When zeros appear, release the button.
3. Meter an exact known volume into an
accurate container. For best results,
meter with one continuous full stream.
4. Check the readout. If the amount
metered is accurate, field calibration is
not necessary. If not, refer to the
Calibration Section for further instruc-
tions.
