SEAGUARD® WTR
Wave and Tide Recorder

The new AADI SEAGUARD® WTR is a robust instrument based on the SEAGUARD® Platform. It is a self
contained instrument for measuring wave parameters,
water level and temperature. The instrument can be
used as a platform for additional measurements (e.g.
CTD, current, dissolved oxygen and turbidity).
Features of the SEAGUARD® WTR:
•tHigh Resolution and low drift
•tLow maintenance needs
•tSelectable interval from 2 seconds to 2 hours
•tSEAGUARD® Studio vizualisation software
•tSmart sensor topology based on a reliable CANbus
interface (AiCaP)
•tOutput parameters: Pressure, Temperature, Tide,
Significant wave height, Maximum wave height,
Mean period, Peak period, Energy wave period,
Mean zerocrossing period, Wave steepness, and
Irregularity of sea-state. The WTR also provides raw
data of the Pressure and Temperature measurements.
•tReal-Time XML Output on RS-422(optional)
•tFor use in sea and fresh water
•tWindows CE based datalogger with TFT based
colour touch panel for configuration
•tMeasurement range: 0 - 400 kPa / ~30m depth

The SEAGUARD® Wave and Tide Recorder measures wave
and tide conditions based on a silicon pressure sensor
4648. The pressure measurements are sampled and
temperature compensated by an advanced Digital Signal
Processor.
The SEAGUARD® WTR application areas are in fixed
installations, either deployed in a seabed installation in
shallow waters, or mounted onto a fixed structure in the
upper water column.
Typical applications for the sensor are measurements of
wave and tide in Ports and Harbors, Marine operations,
Weather forecast, and Climate studies.
The recommended deployment depth for wave
measurements is in the range 6 - 15 meters. The maximum
deployment depth for tide measurements is 30m.
The tide measurement is an average of the hydrostatic
pressure measured over a time period of 10 seconds to
8 minutes (configured by the user). The update interval is
between 2 seconds and 255 minutes.

AADI is a trademark of Xylem Inc. or one of its subsidiaries.

The wave measurements are based on the pressure time
series measured over a time period of 64 seconds to 17
minutes (configured by the user). The update interval is
between 2 seconds and 255 minutes.
The output parameters from the SEAGUARD® WTR are
easily presented in SEAGUARD Studio.
The SEAGUARD® WTR and the AADI smart sensors are
interfaced by means of a reliable CANbus protocol (AiCaP)
using XML for plug and play capabilities. The smart sensors
can be mounted directly on the top end plate of an AADI
SEAGUARD® and are automatically detected and recognized.
The SEAGUARD® WTR can be used with AADI Real-Time
Collector for Real-Time data.
The SEAGUARD® WTR has 2 battery compartments for
long deployment time.
The SEAGUARD® WTR can be equipped with a Conductivity sensor for calculation of Salinity, Density and Sound
of speed.
