Microwave wave height meter

Product Code:WM-2

Continuous wave height measurement and recording from vessels at sea, offshore towers, and river mouth weirs

The WM-2 microwave wave height meter can measure and record continuous wave height data from ships, offshore towers, and other offshore platforms. The detector can measure wave heights without direct contact with sea water.

Example wave height meter configuration

The system is composed of a detector (a sensor unit and an accelerometer), a relay component, and a computation component. The data from the detector can be used to calculate various statistical analysis values. For moving platforms such as ships, the accelerometer detects the movement component. This makes it possible to perform continuous actual wave height measurement even while the ship is in motion.
