In complex flow velocity areas such as estuaries, it is possible to measure flow velocity at each vertical layer.
The Aqua Doppler Profiler is a flow velocity measurement device that uses next-generation ultrasonic Doppler technology, suitable for seabed, mooring systems, and buoy observations. Its compact and lightweight body is equipped with compass, tilt, pressure, and temperature sensors, which are recorded in the built-in memory. The sensor head features three transducers arranged at a 25-degree angle, utilizing three ultrasonic beams to obtain flow velocity profiles at any layer thickness (minimum 30 cm) and up to 128 layers. With the standard 9MB memory and internal battery, it can conduct observations for 2 to 4 months. Additionally, by adding batteries, the observation period can be further extended. 【Features】 - No calibration required - Adjusts ultrasonic transmission intensity to reduce battery consumption in shallow waters - Automatically detects installation orientation - No electrical corrosion - No protruding parts, resulting in fewer failures and accidents For more details, please contact us or download the catalog.
