History of Innovation
Mueller Systems has a rich heritage in providing innovative water infrastructure products and services and offers technologically advanced metering systems for electric, gas and water systems. For more than 150 years, municipalities have relied on Mueller Water Products to lead the industry, and that tradition continues with Mueller Systems.

Mueller Water Products, through Mueller Systems, was a pioneer in Automated Meter Reading (AMR) technology, which allows utilities to automatically collect data from water or energy meters. As the needs of municipal utilities evolve, Mueller Systems is introducing more robust solutions. Mueller Systems has developed true two-way capabilities for AMI, which gives utilities the ability to manage their systems remotely. Additionally, the Mi.Net® Mueller Infrastructure Network for Utilities goes beyond conventional AMI systems, enabling utilities to deploy newer technology in stages rather than replacing all systems at one time.

Take a closer look below at the history of innovative products and services offered by Mueller Systems to municipalities to help them optimize their operations.
