The SonTek/YSI FlowTracker Handheld ADV (Acoustic Doppler Velocimeter) uses our proven ADV technology in a compact, hand-held package to make accurate, high-precision water velocity measurements in natural streams, weirs/flumes, and open channels related to irrigation, stormwater, water treatment, and mining. Designed with the field user in mind, the FlowTracker easily attaches to top-setting wading rods and features an automatic discharge computation program that is based on USGS/ISO methods.
SonTek's ADV technology has been well established for many years as the preferred sensor for high-resolution, 3D water velocity measurements. This same technology has been incorporated into the FlowTracker to provide the same ADV functionality from a simple keypad/LCD interface, allowing rapid data collection and analysis in many natural stream and open channel environments.
The FlowTracker collects a burst of data at user-selected measurement locations. The burst length is adjustable, allowing you to record mean velocity over a defined averaging period. A simple, menu-driven interface prompts you to enter your data collection parameters.
The FlowTracker uses acoustic Doppler technology to measure 2D or 3D flow in a small sampling volume located a fixed distance (10 cm) from the probe. Sound generated by the transmitter bounces off suspended particles in the water. This reflected sound returns to the receivers, is averaged together by the processor, and results in water velocity measurements that are recorded at a rate of once per second.
