Peter Petroff established American Digital Systems (ADS) in 1975 after a career with NASA as a lunar guidance system engineer under Dr. Von Braun. From his garage in Huntsville, AL, Mr. Petroff applied his space technology expertise to measuring municipal collection system flows. The result was the introduction of Doppler flow monitoring, which Petroff grew into a thriving business by the 1980s. The installation of over 400 monitors networked to a central computer in Sydney, Australia in 1990, was an important milestone in the Company’s history. The industry took note of the expertise required to deploy Sydney’s sophisticated network. ADS continues to establish flow-monitoring networks in numerous cities across the world today.
