Since 1992, SonTek has been making water velocity measurement practical, reliable, and accessible. As a Xylem brand in the Analytics division, we have the backing of a Fortune 500 company to design and produce the most reliable products in the water industry. This includes a broad range of acoustic Doppler instruments (ADCPs) that use sound waves to measure how fast and where water is moving—or if it’s moving at all. Trusted by hydrologists, scientists, engineers, and water resource professionals around the world, our technology is used in rivers, lakes, estuaries, coastal zones, and deep oceans alike.
Backed by a dedicated team of global experts, SonTek offers the support, training, and guidance you've come to rely on—wherever and whenever you need it. From the Amazon to your local creek, our instruments and people are here to help you measure with confidence.
