Microwave Type Wave Height Meter WM-2

PDF Catalog DOWNLOAD

WM-2 measures and records consecutive wave height data from the sea platform in a ship or an oceanic tower, etc.

 ・ The structure of sensor is strong enough to withstand the impact of sea water.

 ・ The signal processor can output the real value(real wave height value)

 ・ The observation accuracy is less than ±10%

 ・ Since wave height measurement is done without any direct contact of sensor with sea water , this system is almost maintenance free.

 ・ This system can be installed not only in a vessel but on an transonic tower, on a pier and on an estuary weir.

The accurate value of sea wave height is obtained by removing effect of hull agitation (that is value received from accelerometer).

 

It is a value when measured wave height was between 0.2~8.0m and wave period was between 3~15 seconds.

 

We supply our WM-2 for Research Vessel 'Sagar Nidhi' of INCOIS (Indian National Centre for Ocean Information Services).

User's voice "The real time data for wave height will be used by INCOIS for validation of sea state forecast."
