ZPulse® Doppler Current Sensor
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.
