Peter Petroff Establishes ADS

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, 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. In that decade, ADS flow-monitoring networks had been established in a number of cities throughout the United States.

ADS Achieves ISO Certification

ADS LLC is dedicated to delivering quality products and services to our customers. To this end, we firmly believe in the importance of a Certified Quality Management System (QMS) that is centered around ensuring the implementation of quality processes through continuous improvement and customer feedback. The commitment to maintain and improve quality is a company-wide objective and is evident at all levels of the organization. ADS solidified this commitment by achieving ISO 9001:2008  certification in 1994 and maintaining this certification today.

Flow Monitor Accuracy Greatly Increased Over a Wide Range of Hydraulic Conditions

ADS develops and incorporates Monitor Level Intelligence (MLI) in their Flow Monitors.

ADS Achieves ATEX Certification

Safety is extremely important to ADS. This includes designing and manufacturing our products to operate safely in their installed application. Our commitment to this safety is embodied in the ATEX certification we received in 2000. The ADS FlowShark Triton is certified intrinsically safe for use in potentially explosive atmospheres.

ADS is Awarded the EPA’s Environmental Technology Verification (ETV)

The U.S. Environmental Protection Agency established the ETV (Environmental Technology Verification) to prove the performance of various environmental technologies under specific, predetermined protocols and stringent  quality assurance procedures. ADS Models 4000 and 3600 flow monitors performed to their published specifications under rigorous, unbiased laboratory and field testing conducted under the U.S. Environmental Protection Agencies ETV program.
