Mueller Systems Introduces Its Magnetic Flow Meter for the Water Industry
New water meter offering helps municipalities accurately account for water use while reducing operating costs

CLEVELAND, NC (June 12, 2011) - Mueller Systems, a leading provider of innovative water infrastructure products and services and technologically advanced metering systems for water, electric and gas systems, announced HbMAG—the company's magnetic flow meter for the water industry. Mueller Systems is a subsidiary of Mueller Water Products, Inc. (NYSE:MWA), a leading North American provider of water infrastructure products and services, and offers a full line of residential, fire line and commercial meters, automatic meter reading (AMR)/advanced metering infrastructure (AMI) systems and related products that optimize the delivery and use of water and energy.

HbMAG enables municipalities to measure water flow more accurately than with most traditional meters—with virtually no reduction in head pressure, helping municipalities to significantly reduce pumping costs, improve conservation and accurately account for water consumption. Its accurate measurement of water flow and improved operational efficiency for municipalities' potable, wastewater and reclaimed water systems, makes it a viable replacement option for applications that previously utilized a compound or horizontal turbine meter and for use in applications where minimal head pressure loss is vital, such as fire protection systems. HbMAG's compact and highly durable design contains no moving parts—which means virtually no wear and tear or maintenance costs for municipalities—and it can be installed vertically or horizontally for ultimate flexibility in system retrofits and designs.

HbMAG displays detailed usage information on-site. And, it can fully integrate with Mueller Systems' two-way fixed network solution—Mi.Net™ Mueller Infrastructure Network for Utilities—or Hot Rod™—Mueller Systems' advanced AMR system—for intelligent performance, diagnostics, billing accuracy and customer service, as it enables municipalities to remotely collect usage information. HbMAG enhances the many benefits of the Mi.Net System, which include on demand meter readings, e-mail alerts and alarms based upon near real-time information, and the ability for utilities to best manage your water resources through on-going access to custom data and information.

"HbMAG is one of Mueller Systems' latest smart water innovations that helps municipal water service providers to efficiently optimize their measuring capabilities while reducing operating expenses and improving conservation—especially when used as part of an AMI or AMR system," said Hassan Ali, vice president and general manager of Mueller Systems.
