ADCP - RDI Streampro

This Acoustic Doppler (water) Current Profiler (ADCP) can measure water velocity and discharge in shallow streams, ranging from 15 to 200 cm deep, in minutes.

This may be mounted on either a wading rod or on a floating platform, such as that used with NIWA's ADCP Traveller. With the floating platform you don't even have to get your legs wet. The floating platform is towed across the stream at constant speed on a tagline.

Streampro's 'bottom tracking'  capability lets it move continuously across the stream to obtain a discharge measurement in two or three minutes, instead of up to an hour using the older point-by-point method.

Streampro collects the data in real-time and transmits it over a wireless link to a handheld computer.
