A new technical animation demonstrates the operation of the Hydro-Guard S.M.A.R.T. Water Quality Monitoring & Flushing System, Mueller Co.’s latest cellular communication-based intelligent water technology. The S.M.A.R.T. system can be outfitted with a variety of water quality sensors, allowing the system to flush when disinfectant residuals or other water quality conditions exceed parameters set by the user. The technology conserves water and saves money when compared to conventional flushing and monitoring techniques.
