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.
Features
Simple hand-held interface with real-time velocity display
Automatic discharge computation program based on USGS/ISO methods
Shallow-water 2-axis (2D) probe measures in depths as little as 2 cm (~1 in.); optional 2D/3D probe is available.
2-m probe cable (3-m cable optional)
Remote sampling volume of 0.25 cm3 located 10 cm from the transducer
FlowTracker software package
Internal memory for 80,000 measurements (non-volatile)
Temperature sensor
Built-in recorder, battery power, and RS232 interface
Mounting pin on ADV probe (Note: Complete mounting brackets for top-setting wading rods are available.)
