Seaguard® Water Level Recorder (WLR)

SEAGUARD^® Water Level Recorder (WLR)

The new SEAGUARD^® WLR is a robust instrument based on the SEAGUARD^® Platform.

This self-contained instrument measures:

• Tide level
• Tide pressure
• Pressure
• Temperature

Tide levels are preliminary, internally calculated estimates based on fixed, user selectable values of atmospheric pressure and water salinity.

Compensation for actual atmospheric pressure and salinity can be made during post-processing if such data are available. Tide pressure is an average of hydrostatic pressure over the integration time.

The SEAGUARD^® WLR 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 tide in ports and harbors
• Marine operations
• Weather forecast
• Climate studies.

Three versions of the Tide Sensor are available:
Tide sensor 4647A - Depth range: 0 - 30 meters
Tide sensor 4647B - Depth range: 0 - 60 meters
Tide sensor 4647C - Depth range: 0 - 300 meters
