SonTek

SonTek - a Xylem brand

SonTek, advancing environmental science in over 100 countries, manufactures affordable, reliable acoustic Doppler instrumentation for water velocity measurement in oceans, rivers, lakes, canals, harbors, estuaries, and laboratories. Our instruments use sound waves to tell you how fast water is moving, where it is moving, and even if it is not moving at all. Our customers are scientists, engineers, hydrologists, research associates, water resource planners and anyone that needs to collect velocity (speed) data in every kind of body of water imaginable.

SonTek Argonaut-ADV

SonTek Argonaut-ADV for Shallow Water Flow Monitoring

Robust velocity measurements in a compact, easy-to-use package

Providing robust velocity measurements in a compact, easy-to-use package, the SonTek Argonaut-ADV is the ultimate instrument for shallow water flow monitoring. Ideal for low-flow applications in shallow streams, marshes, lakes, or water treatment facilities, the 3-axis (3D) Argonaut-ADV's advanced Doppler technology measures single-point velocity away from flow obstructions. All signal processing is done internally, allowing the Argonaut-ADV to be readily integrated with a wide range of additional sensors.

Sontek ADP

SonTek ADP® - Acoustic Doppler Profiler

A high-performance, 3-axis (3D) water current profiler

The SonTek ADP (Acoustic Doppler Profiler) is a proven, capable and versatile, high-performance, 3-axis (3D) water current profiler that is accurate, reliable, and easy to use. 

SonTek-IQ® Series

SonTek-IQ® Series

Ideal for monitoring flows in canals, culverts, pipes, and natural streams

Ideal for monitoring flows in canals, culverts, pipes, and natural streams, the SonTek-IQ starts with a custom flow algorithm derived from hundreds of field measurements. Four velocity beams profile water velocity in 3-D - both vertically and horizontally - ensuring complete coverage of the velocity field. The built-in pressure sensor and vertical acoustic beam work in tandem to measure water level. Simply input the channel geometry using the intuitive SonTek-IQ software and you are outputting flow data in minutes.

10MHz ADV

SonTek 10-MHz ADV®

Proven, accurate solution for high-precision, 3-axis (3D), velocity measurements

The SonTek ADV is a single point, high resolution Doppler current meter which provides 3-D velocity measurements in a remotely sampled volume. The ADV is a bistatic Doppler current meter. The term bistatic refers to the fact that the ADV uses separate acoustic transducers to transmit and receive sound energy. The ADV transmitter generates sound with most of the energy concentrated in a tight cylindrical volume, while the receivers are the most sensitive to sound coming from a slightly broader angular range. The transducers are mounted such that their beams intersect over a volume located some distance away, called sampling volume. This document presents a basic description of the effects of the finite sampling volume on the accuracy of the velocity measurements.
