The Aanderaa Current Sensors are based on the backscatter acoustic Doppler principle.

Doppler Current Sensor (DCS)

The Aanderaa Doppler Current Sensor is a rugged, true vector averaging sensor for measuring current speed and direction in the sea. The sensor has built-in compass and tilt sensor and may also output sea temperature. The speed range is 0 to 300 cm/s. Low current drain and flexible sampling schemes. New multi-frequency Doppler Current Sensor (DCS) with ZPulse technology achieves better performance using only half the power than previous models. The new, fast response compass and tilt circuitry has no moving parts achieving excellent performance in unstable areas such as in the wave zone close to surface.

In-line  ZPulse DCS Doppler Current Sensor 5800 / 5810

The inline ZPulse DCS has been designed in order to easily integrate into systems offering a compact and elegant solution.  It is based on a modified version of the ZPulse Doppler Current Sensor 4520. The unit connects to a combined mooring and signal cable in one end and allow for connection of a continuation cable at the opposite end. It can hold a load of up to 1300 kg. It has been developed to replace the previous Aanderaa DCS 4100 using newer technology and extending capabilities.

DCPS 5400/5400R/5402/5402R/5403/5403R - Doppler Current Profiler Sensor

The Doppler Current Profiler Sensor (DCPS) is a medium range, 600kHz current profiler smart sensor. If features innovative development of the acoustic profiling ability to collect high quality current information also on moving and tilting platforms. The 5400/5400R version is 300m depth rated, the 5402/5402R version is 4500m depth rated and the 5403/5403R version is 6000m depth rated and is intended for commercial as well as research use. It comes with an integrated temperature sensor that can be calibrated on request.
