1. Introduction
This document is intended to assist professional installers with Mueller Systems AMR
transmitters. It provides instructions on how to successfully connect, operate, and
troubleshoot the transmitters. Mueller’s remote meter reading transmitters were
designed with an “easy to install approach” for utilities. The SM6-HOTRODV2LO, SM6-
HOTRODV2MED, and SM6-HOTRODV2HI allow the utility to receive data from any Mueller
water meter equipped with a Translator register. The transmitter collects data from the
register and transmits it via radio frequency (RF) to be collected by a mobile receiver.

The thermoplastic housing design reduces material and helps eliminate air space within
the transmitter, Figure 1. Mounting features include two holes for wall installation and a
1/2 inch female PVC pipe fitting for easy pit installation. The transmitter units are
molded from grey plastic. The high power unit should only be used within a metal meter
box. The medium power unit should only be used within a plastic meter box. The low
power unit should only be used outside a meter box. A quarter wavelength whip antenna
is utilized. A primary lithium battery is utilized to power the device. The device will
transmit readings every three seconds, but that value is configurable at the factory. The
electronic design utilizes the latest in RF microchip technology which reduces cost and
increases reliability when compared to older RF designs. In order to protect the AMR
transmitter from moisture ingress, the design incorporates the use of thermoplastic
injection molded housings, rubber seals, a potting compound that completely encases the
internal electronics and a coated circuit board which provides the final barrier of
protection. Internal wire strain relief has been built into the housing to protect the wire
