1. Introduction
The Mueller Systems Mueller Cellular Node is intended for indoor and outdoor use
as an unattended Automatic Metering Infrastructure (AMI) and control device. The
Mueller Cellular Node is fully self-contained and battery powered device with no user
accessible controls.
The Mueller Cellular Node for Residential Metering (“Mueller
Cellular Node”) is a device that incorporates a microcontroller, a
LTE MODEM , and battery (DC power supply) for the purpose of
logging and forwarding water meter readings to the Mueller
Systems servers. The Mueller Cellular Node comprises 2
primary communication and processing modules, the SIERRA
HL7800 LTE MODEM, and the Silicon Labs BlueGecko
EFR32BG12. The Mueller Cellular Node provides a direct
connection to all Mueller water meters equipped with a
Mueller encoder register. The primary function of the Mueller
Cellular Node is to provide full, two way reliable and secure data
communications via the existing cellular networks. The Mueller Cellular Node will also
autonomously send messages to the server when various events or alert conditions are
detected, such as potential leak or theft of service.
Meter reading interval is remotely settable. Information retrieved from a water meter is
stored temporarily within the Mueller Cellular Node unit's internal memory. As a default,
the Mueller Cellular Node will transmit hourly meter data at a predetermined time once
per day, via the cellular network to the Sentryx system host server for analysis and
storage. On demand reads to the Mueller Cellular Node can be requested at any point in
time.
The contents of this installation manual are intended for technically qualified personnel
of water and energy distribution utilities who have been trained and are technically
qualified in local safety procedures for installation of the device.
2. Construction
The Mueller Cellular Node product consists of a printed circuit board which is encapsulated
to provide complete protection against shock and water intrusion. The enclosure is made of
UV stable, high- density thermoplastic and is completely waterproof. The UV stable,
thermoplastic housing design provides a compact, waterproof enclosure that is lightweight
and easy to handle and install. The Mueller Cellular Node has integral mounting brackets
for both pit and wall installations. One D size lithium battery provides plenty of power
for reading the register and sending RF data.
• To protect the AMI device electronics from moisture ingress the design
incorporates the use of thermoplastic injection molded housings, rubber seals,
a potting compound that completely incases the internal electronics and a
coated circuit board which combine to provide a formidable barrier of
protection against water intrusion.
• Internal wire strain relief has been built into the housing to protect the wire
connections against damage. Please note that meters or registers should never
be carried while supported only by the Mueller Cellular Node transmitter or wiring.

• A LTE PCB antenna is located in the upper housing to provide RF communication.
• A single D cell long life Lithium battery is located in the lower housing which
provides power for register interrogation and data transmission for a calculated
battery life of up to 10 years.
• There are no customer serviceable parts inside the Mueller Cellular Node housing.
Batteries are not replaceable.
• The electronic design utilizes the latest RF microchip technology which
increases reliability when compared to older RF designs.
3. Installation
Mueller Cellular Node modules support two mounting options, either mounting to a ½”
PVC pipe for pit set installations or affixed to the side of a building. Pit set
installations require no drilled holes through the lid and are mounted beneath the
polymer meter box lid for security and ease of installation on PVC pipe. Surface
mounts are easily accomplished with the integral mounting brackets and two screws
(not included).
3.1 Pit Set Installation
Please note that meters or registers should never be carried while supported only
by the AMR transmitter or wiring.
Tools Required: Length of ½” PVC pipe for pit depth, hammer
1. PVC pipe should be cut to the proper length and installed deep
enough in the floor of each meter box that subsequent flooding
will not allow the stake and Mueller Cellular Node to change
position. The Mueller Cellular Node includes a ½” female PVC
pipe fitting for easy pit installation.
2. For maximum radio performance, once installed, the top
of the transmitter should be located approximately ½” inch
below the pit lid in the center of the meter box to maximize RF
performance.
3. Once the PVC stake is installed, the Mueller Cellular Node
should be pushed down onto the stake by hand until the
interference fit engages securely. Two solid stops are molded
into the PVC Installation Slot to prevent the wire from
being pinched when installed.
Never hammer Mueller Cellular Node onto the stake since this may result
in damage to the electronic components inside the unit.
4. Always mount the Mueller Cellular Node in a vertical orientation, with the
antenna compartment on top and the battery compartment on the bottom.
