Current, Wave and Tide Recorder
A device for measuring the parameters: recorded wave direction, wave height, flow rate, tide, and seawater temperature. Application: deploy measurement at a fixed point on the sea, collecting equipment after a certain period of time to collect and analyze data. The device is available with the ability to expand the installation of more sensors for measuring hydrological and environmental parameters, adding accessories and options for transmitting all real-time measurement data.
