The lowest ADV velocity range,
±
3 cm/s, will yield good results for flows down to about
0.1 cm/s. If working in an environment with lower flows, the ADV software can be modified to
use lower velocity ranges that will improve performance in flows less than 0.1 cm/s. For more in-
formation about using the ADV for low flow applications, contact SonTek.
