WAvedirection RECeiver, WAREC

This unit together with a personal computer provides data reception and data handling at site.

The unit is equipped with an RS232 communication port.

Control, programming, read out and testing is by means of a personal computer (not included in the price of the WAREC).

With the Warec-PC on-line 3D datahandling software (DOS pc) following information is presented (almost real time) :

- Administration data

- Spectral density	S (f)

- Wavedirection

- Beamwidth spectrum

- Hs	4 M0

- Tz	T02

- Sea surface temperature

- Data quality report

- Battery condition

- Wave statistics, for instance Hmax, Tmax, H1/10, T1/10, H1/3, T1/3, Havg,Tavg,EPS4 etc.

Triangle

The use of a triangle is advisable at places where risk of ships collision exists to prevent spinning of the buoy; excessive spinning may damage the sensor.
