Accusonic - History

With over 35 years of experience, Accusonic Technologies is the proven leader in design, development, and production of high-accuracy ultrasonic transit-time flow measurement systems. Thousands of Accusonic flowmeters are in use at hydroelectric, fossil power, water treatment and distribution, and wastewater plants and projects around the world.

Founded by a group of engineers from the Woods Hole Oceanographic Institution and originally incorporated as Ocean Research Equipment (ORE) in 1961, Accusonic Technologies began development of transit-time flowmeter technology in the late 1960’s and delivered their first multiple-path flowmeter systems for both pipeline and open-channel flow monitoring to the California Department of Water Resources (DWR) in the early 1970’s.

 
Grand Coulee, Washington
World's 4th Largest Hydro Plant
10 Accusonic Flowmeters
 
The inherent accuracy and reliability of Accusonic flowmeters led to ever-growing use in critical high-value hydroelectric and water transport projects. By the 1980’s Accusonic had established its position as a premier provider of flow measurement technology and expertise for large pipes and open channels, based on a solid record of proven accomplishments.

These include long-term flowmeter installations at the world’s largest hydroelectric projects:
