IMPORTANT NOTICE
Use TM Series meters with water and other chemicals compat-
ible with wetted components (see Specifications Section). Do
not use with fuel or incompatible chemicals. TM Series meters
are available with one of the following electronic options: Local
Display, Conditioned Signal Module (Open-Collector), Local
Display with Pulse-Out (GG Model), Local Display with 4-20 mA
(GX Model), 4-20 mA Output Only (GA Model) or Scaled Output
(SC Model). Refer to each 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.

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 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. For Spigot (Pipe) End - Use only primer and solvents ap-
proved 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 com-
puter display area. However, the customer should check all
parts before attempting cut.
For NPT Fittings - Wrap all connections with 3 to 4 wraps
of thread tape. Make sure the tape does not intrude into the
flow path.
3. Attach meter with arrow pointed in the direction of the flow.
4. For NPT Fittings - Hand tighten the meter at the housing
ends. Do not use a wrench or similar tool to tighten. This
can damage the housing.

Power Supply The “X” markers represent the digits of the K-factor. This allows a K-factor range of 0000.1 to 9999.9. The switches are arranged The GPI Scaled Pulse circuit is designed to operate correctly and labeled as follows: when supplied with any DC voltage between about 5-30 volts, referenced to any of the COM terminals. - Page 23 If you need to set a very large K-factor (larger than 9999.9), with a standard unit, you will have to follow the instructions for getting an output pulse every 1/10th unit. That is, multiply the meter’s K-factor by 0.1, and then enter the result on the switches. Remember that you will get an output pulse every 1/10th unit instead of every whole unit.
