The Aanderaa Tide sensors are compact fully integrated sensor for measuring the tide conditions.

Tide Sensors 5217/5217R are compact fully integrated
sensors for measuring the tide conditions. The sensor is designed to be
mounted on the Aanderaa multiparameter SeaGuard® Platform or via cable
connected to SmartGuard datalogger. The standard version has AiCaP
CANbus and RS-232 output. R-version has RS-422 output for longer cable
length.    

The sensor is also available in a vented version. This means that the
sensor is automatically compensated for air pressure. This is done by
use of a compensating unit placed in air and an air-pipe in the cable
between the sensor and compensating unit.

The sensor 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, and climate studies.
