MTU Instruction
for Metron-Farnier Water Meters
Purpose & Scope
This instruction provides wiring information for connecting a STAR MTU to a Metron-
Farnier Water Meter equipped with an OER register.
Metron OER Register
MTU Cable OER Cable
Red R (Red)
Black B (Black)
White G (Green)
Supplies and Tools Required
See Publication 471-2000, General
Installation and Wiring Guidelines for a
complete list of recommended tools and
supplies for MTU Installation.
Application Notes
• The 5-digit Metron OER register must
be configured for an additional trailing
zero for proper operation with STAR
MTUs.
Installation Procedure
Step 1 - Select a mounting location for
the MTU that will allow optimum signal
transmission, and install any needed
wiring. Be sure to follow all General
Installation and Wiring Guidelines as
outlined in Publication 471-2000.
Step 2 – Select the wiring diagram that
applies to the meter you are connecting
and make the appropriate wiring
connections.
a. Direct Wiring to Meter - MTU
wiring is supplied stripped to a
standard length that fits water
meters with screw terminals.
Simply wrap the wires around the
screw terminal and tighten the
screw. It is recommended that the
screws be tightened to no more
than 4 – 5 in-lbs. Overtightening
the screw can stress and possibly
fracture the wire.
b. Water Meter with Integral Cable -
If the water meter is supplied with
an integral cable and a cable-to-
cable splice is necessary, use a
gel-filled wire splice designed for
outdoor (moisture applications) to
seal the individual connections.
Note: When connecting a dual port MTU
to a compound meter, connect port 1
(black jacket) to the primary, or high-flow
register and port 2 (grey jacket) to the
secondary or low-flow register.
Step 3 – Make a final visual check of the
wiring from the MTU to the meter register.
Verify that the cable routing is neat,
secure and professional.
Step 4 – Once installation and wiring are
complete, program the MTU using the
STAR Programmer Software and your
MTU Programmer.
