Aquadopp - 3000 m

The 3000m Aquadopp is designed for deployments down to 3000m and it has all the capabilities of the standard Aquadopp. It is a modern, yet well-proven instrument and it undoubtedly the most versatile single-point current meter on the market. Relative to the standard system, it has a larger diameter (about 84mm vs. 75mm) but it is still made of all plastic parts. As a result, the 3000m model is lighter than the pure-titanium 6000m model and it represents an affordable alternative for the deployment in intermediate waters.

The transducer sensor head is made from machined Delrin materials and the orientation of the beams is either symmetrical or the same as in the standard "moring head" configuration.

In the deep ocean, there are fewer particles than in the upper 500m of the water column. Considerable work has been done with the Aquadopp to understand the factors that affect the acoustic signal strength and to improve the magnitude of the returned echo. This work is reflected in current electronics and transducer design. Verified performance in the deep ocean is documented here.

The most common application for the 3000m Aquadopp is deep-water moorings, where one or more instruments are mounted on a cable that stretches from the bottom to a subsurface float. The instruments can either be clamped directly to the cable or a fin can be used to make sure the instrument is always oriented into the flow.
