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.
