Badger Meter does not currently offer a wall mount enclosure for this product . However, Series 3100 flow monitors can be
wall mounted in the field into any appropriate customer-supplied enclosure .
Electrical Power

Before applying power to this unit, check the Model # label: The Series 3100 flow monitor can be ordered as low voltage 12…24V AC/
DC (3100-0x) or as high voltage 120/240V AC (3100-1x).
Low Voltage 12…24V AC/DC Wiring
The Series 3100 flow monitor has a green, three-terminal connector with screw heads, and requires 12…24V AC/DC to
operate . See
for the current DC draw and AC Volt-Amp requirements . Always use a fused circuit .
Connect the positive end of the power supply to the Series 3100 flow monitor terminal marked LV AC/DC (+), and connect
the negative end of the power supply to the Series 3100 flow monitor terminal marked LV AC/DC (–) . Earth ground can be
connected to the terminal marked EARTH .
Ground should be heavy gauge wire and as
short as possible.
If panel mounting in a metal enclosure,
Ground to door and bond the door to the
enclosure across the hinges with a brad
just long enough to allow the door to
open freely.

High Voltage Power Supply Wiring
The Series 3100-1x is designed to accept a standard EL-712 (NEMA 5-15R) plug similar to those used on many laptop
computers . Power can be 120…240V AC 50…60 Hz . When the High Voltage option is ordered (3100-1x), a power cord is
supplied with the unit .
See
