Product details

Instrument Overview

The handheld acoustic Doppler velocimeter (ADV) is primarily used in laboratory flumes, water treatment facilities, natural streams, surface runoff, lakes, hydraulic models, and can also be applied to river measurements and marine surveys for the rapid measurement of fluctuating flow velocities.

Product Features

(1) Measurement in shallow-water environments with low flow rates that require wading.

(2) Higher sampling frequency and smaller standard error

(3) Standard wading-side rods and brackets

(4) Measure the component flow velocities Vx and Vy, as well as the resultant flow velocity V.
