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.
