Mueller® Meter Xchanger™ System - Mueller Gas Products Division

Mueller ®
Meter Xchanger
System
Enhance customer service and
save time changing gas meters.

Change-out gas meters when you want…
without interrupting service.
Even though most gas
meters can operate reliably
for decades, at some point
meter replacement becomes
necessary. And to date, the
only way to successfully
change a meter has been
to first shut off the gas. Of
course, that can cause a
host of other problems that
can complicate the process.
There’s no doubt that meter replacement is a hassle… that is,
until now.
The intelligent solution
Shutting off the gas is a thing of the past! The Mueller ®
Meter Xchanger
System now lets you work on your own schedule without affecting
the customer’s service. The property owner will probably not even
realize that your crews have been on the scene. And since gas
service is maintained and pilots remain lit, there is no reason for the
customer to be present… and no need for crews to enter buildings.
No more missed appointments or rescheduling problems either–
setting appointments is now a matter of courtesy, not necessity. This
new system truly changes the ground rules!
How the system works
The Mueller Meter Xchanger System is a portable gas meter changeout
system. Within the Mueller Meter Xchanger System are two
nearly identical tools that fit around the meter connections at the
swivels. These tools are easily adjustable to fit 20LT meter bars with
straight or offset swivels. A lightweight aluminum platform, which
clamps to the meter bar, is an integral part of the unit, providing
support for the meter during disconnection– and as a new meter is
positioned and installed. As the tools are attached to the swivels, a
uniquely designed bypass component connects the two tools and
allows safe, uninterrupted gas flow through the service line, until the
replacement meter is installed.
Once the tools are secured, the old connection is mechanically
opened, by manipulating the knobs, levers and slides of the tools.
Gas flow is automatically activated and maintained during the
change-out. The old meter is then dropped down and removed, as
the swivel ends are automatically sealed to prevent gas leakage.
To install a new meter and
gaskets, the whole process
is essentially reversed. After
the new meter is in place, the
tools can purge excess natural
gas through bleed-off valves.
A battery-powered electronic
monitor is also part of the
system. It monitors high/
low pressure to the property
owner’s service. In the event
service pressure fluctuates outside operator set limits, patterns of
LEDs are illuminated to indicate what occurred and remain lighted to
alert the service technician.
Designed for long service
Mueller has designed the tools for durability and easy access to
seals during routine maintenance. The primary parts of the tools
are also constructed of lightweight aluminum. Critical moving parts
on the unit are made of either stainless steel or bronze for superior
durability, low maintenance and long life. All system components
including monitor are nested into a form-fitted, padded, heavy-duty
carrying case that is both compact and lightweight for easy transport
from location to location.
