Aanderaa, a Xylem Brand products

The single-point current meter series are a completely new generation of current meters based on the SEAGUARD® datalogger platform and the ZPulse® multi-frequency Doppler Current Sensor (DCS). SEAGUARD® Products are based on modern technology and are the basic modules of our underwater observatory. They may be used as a multi-parameter instrument in the sea and in freshwater and feature a modular plug-and-play architecture. The new single-point, Recording Current Meter(RCM) series featuring the new ZPulse™, multi-frequency Doppler Current Sensor and CANBus based AiCap smart sensor technology.

The SeaGuard DCP (Acoustic Doppler Current Profiler) measures currents and can be extended with wave direction, oxygen, conductivity, turbidity, temperature, and serial sensors.

The optimal solution to measure directional waves, currents and water quality in one instrument. The SeaGuardII DCP Wave is a 600kHz Doppler Current Profiler able to measure directional wave parameters and currents from a bottom mounted installation. The Acoustic Wave software 5759 used by the DCPS implements unique features to improve the wave measurement accuracy by optimizing the signal to noise ratio. Maximum deployment depth is 40m in normal scatter conditions.The SeaGuardII DCP Wave is available as a self-recording instrument. It can be easily integrated into a real-time system offering reliable two-way communication.

A self-recording dedicated current meter with Bluetooth for communications and data retrieval - now with the possibility to integrate a pressure sensor! The RCM Blue is a self-recording Current Meter which also measures water temperature in salt or fresh water, and a battery container with battery capacity up to 70Ah.

The Aanderaa SEAGUARD Sensor String Systems are complete and flexible subsea observatories for measurements of e.g. dissolved oxygen, conductivity, temperature, current, pressure and tide.

The acoustic based wave instrument, SeaGuardII DCP Wave, the swiss army knife of ADCP`s with the possibility to measure Ocean Waves, Ocean Currents, Tide and Water quality all from one single instrument. The acoustic based wave SeaGuardII DCP Wave, the swiss army knife of ADCP`s with the possibility to measure Ocean Waves, Ocean Currents, Tide and Water quality all from one single instrument. For wave measurements it uses an adaptive pulse technology that automatically switches between 3 different acoustic modes (2 broadband and 1 narrowband mode) to give optimize the wave measurement accuracy.

Measure pressure based Waves with the Aanderaa Wave Sensors- compact fully integrated sensors for measuring wave and tide conditions. The 5218 wave sensor is designed to be mounted on the Aanderaa SeaGuard top-end plate or connected to SmartGuard using AiCaP CANbus or in other measurement systems using the RS-232 interface. The 5218R wave sensor sensor is designed for use with long cables by means of RS-422 full duplex interface. Both wave sensors are based on a silicon piezoresistive pressure sensor. The pressure measurements are sampled and temperature compensated by an advanced Digital Signal Processor. The wave 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.

Accurate Ocean Based wave measurements are critical in applications such as offshore wind farm development, navigation, cable laying, breakwater building, and bridge construction. Waves also result in continuous loads on marine structures, including docks, moorings, and offshore platforms. Waves are challenging to measure. Variables to consider when collecting wave data include the depth of the measuring device, proximity to shore, wave types, and available infrastructure from which to measure. Several methods for measuring waves are available, and careful selection of the best approach is needed to get the optimal result.

The MOTUS (movement in Latin) Wave Buoy is a perfect solution for collecting environmental data in coastal areas. Collect reliable environmental data with MOTUS Wave Buoy. The MOTUS (movement in Latin) Buoy is a perfect solution for collecting environmental data in coastal areas. The platform used for collecting data is a robust buoy which has proven to be an excellent platform for providing high accuracy and reliable meteorological and oceanographic data. The wave buoy can effectively combine various Hydrological and Meteorological parameters. Basic parameters as wind, waves and currents can easily be expanded to include sensor packages with different water quality sensors. Data is controlled and synchronized by the data management systems that Xylem Analytics offers which also controls and powers the real-time communication. This provides a low power efficient system offering long-term deployment capabilities.

Turn your buoy into an intelligent data collecting platform with the Aanderaa MOTUS Stand-Alone Sensor. There are numerous ways of measuring Ocean Waves. At Aanderaa we have focused on three different types of measurement. One option is the MOTUS Directional Wave Sensor suitable for integration on different buoy types. It is intended for commercial as well as research use. The sensor processes wave data and is configurable to present parameters and wave spectrum directly. The sensor can be connected to a SmartGuard using the CANbus based AiCaP protocol. It can also be connected to a PC or third party systems through the RS-232 interface.
