Aquadopp profiler hypersonic wave velocity
An aqua Doppler profiler is a new generation of ultrasonic Doppler velocimetry. Mooring system? Suitable for buoy observation. Small size? Lightweight body compass? Inclination? Pressure? The temperature sensor is equipped, and it is recorded in the internal memory. The sensor head has three transducers that are tilted at 25 degrees and uses three ultrasonic beams to provide any layer thickness (Zui 10 cm). Get the velocity profile at the number of layers. It is possible to observe for half a year (one hour interval) with a 9-mb memory and an alkaline battery with the target. And zui Additional 4gbps and battery can also extend the observation period.
Small size? Light weight
Calibration required
Ultrasonic emission intensity adjustment reduces battery depletion in shallow water
Automatic detection of vertical direction
Electroless
Because there is no projection, there are few failures / accidents
